InfraOptimization EBS R12.2 Architecture
A Tier is a logical grouping of services, potentially spread across more than one physical machine. The three-tier architecture that comprises an Oracle E-Business Suite installation is made up of the database tier, which supports and manages the Oracle database; the application tier, which supports and manages the various Oracle E-Business Suite components, and is sometimes known as the middle tier; and the desktop tier, which provides the user interface via an add-on component to a standard web browser. Application Tier Services Root services, Web Entry Point services, Web Application services, Batch Processing services, Other services A Node is a logical set of processes running on one hardware machine. Sometimes a node is also referred to as a "server" or an "instance". In a single-node installation of Oracle E-Business Suite, all the Applications processes (including the database processes) run on one node, whereas in a multi-node installation, the processes are distributed across multiple nodes. For example, Node 1 : DB 11.2.0.3, Node 2: Web and forms, Node 3 : concurrent manager. A multi-node installation of Release 12 supports both shared and non-shared application tier file systems. A Service is a functional set of Oracle E-Business Suite application processes running on one or more nodes. Where applicable, the term 'service' is replacing the more traditional term of 'server'. For example, Web services process HTTP requests, and Forms services process requests for activities related to Oracle Forms. The Concurrent Processing server supports data-intensive programs that run in the background.

Understanding Three‐tier Technical Architecture: EBS R12.2 Three-Tier Architecture Perspective EBS R12.2 Technology Architecture Desktop or Client Tier - provides the user interface using a web browser to access the applications. Application Tier - The application tier, sometimes referred to as the middle tier, hosts the various services and servers that implement and execute the business logic, and mediates communications between the desktop tier and the database tier. Database Tier - supports the Oracle RDBMS and is the main data storage area. The database server does not communicate directly with desktop clients

Oracle Applications Manager. OAM & AutoConfig HTTP Configuration. Most HTTP configuration is managed via native Oracle WebLogic Server tools, Fusion Middleware Control, or manually editing of the configuration files. Only a limited set of HTTP configuration files are maintained via AutoConfig. Fusion Middleware Control Configuration of oacore, oafm, forms and forms-c4ws services Properties for the oacore, oafm, forms and forms- c4ws services, including the classpath and JVM arguments, need to be updated through native WebLogic tools such as WebLogic Administration Console. The context variable values are used only to set the initial values during managed server creation. WebLogic Server Admin Console Managing JVM instances of the oacore, oafm, forms and forms-c4ws services. Each JVM instance of a service corresponds to a managed server of that service type. The number of instances needs to be controlled by explicitly creating or deleting managed servers for the service.

InfraOptimization Oracle Applications Technology Layer The Oracle Applications technology layer is an integrated collection of components whose functionality is applicable to all Oracle Applications modules, i.e. CRM, HRMS, Financials, Manufacturing. Components in the Oracle Applications technology layer include: Applications DBA (AD) Set of tools for administration Application Object Library (FND)  Consists of a collection of reusable code, programs, and database objects that provides common functionality across all products. Applications Utilities (AU)  To maintain the Oracle Applications system. Workflow (WF)  To Model and maintain your business processes using a graphical workflow builder. Alert (ALR)  To email system notifications to users when an exception or event occurs. OA Framework (OAF/FWK)  A Java and XML-based development method to develop HTML-based applications Oracle XML Publisher (XDO)  To produce output reports in the desired format.
InfraOptimization Oracle Applications Database Objects • Data objects - Used for storing and accessing business data. These objects include tables, indexes, sequences, and index-organized tables. • Code objects - Used to process the data. These objects include triggers, PL/SQL packages, Java stored procedures, synonyms, and views. • Hybrid objects - Used to both store and process data. Materialized views are an example of hybrid objects.
InfraOptimization Oracle Applications Schemas Product Schema and its own objects Code Objects Schemas Used During Signon When you sign on to Oracle Applications, you initially connect to the public schema, APPLSYSPUB. Once your user name and password have been verified, Oracle Applications connects you to the APPS schema and allows you to choose a responsibility. You can then use the Forms interface or HTML interface to access data that resides in a product schema. (Global Schema) a better name for APPLSYS would or could be FND

EBS R12.2 Login Process Reference Doc ID 1984710.1  When a HTTP request is made for EBS, the request is received by the Oracle HTTP Server (OHS). ($FMW_Home/webtier/instances/EBS_web_<instance_name>_OHS1/config/OHS/E BS_web_<instance_name>/httpd.conf)  When the configuration of OHS is for a resource that needs to be processed by Java, such as logging into EBS, the OHS configuration will redirect the request to the Web Logic Server (WLS) Java process (OACore in this case).  WLS determines the J2EE application that should deal with the request, which is called "oacore".  This J2EE application needs to be deployed and available for processing requests in order for the request to succeed. The J2EE application needs to access a database and does this via a datasource which is configured within WLS. All code must access the data model via the APPS synonym!

InfraOptimization AutoConfig Instantiation Mechanism AutoConfig Operation • AutoConfig template files are used as the starting point for creating site-specific configuration files. AutoConfig evaluates the context variables in a template file, determines the actual values required, and creates a configuration file with these values substituted. This process, described in more detail later in this chapter, is called instantiation. There is one template file for each configuration file. Template files are located in the various <PROD>_TOP/admin/template directories on the application tier, and in the <RDBMS_ORACLE_HOME>/appsutil/template directory on the database tier. • AutoConfig driver files are used to list the corresponding template files and locations, and specify the commands to be executed. For example, the commands might update profile options. Driver files are located in each <PROD>_TOP/admin/driver directory on the application tier, and in the <RDBMS_ORACLE_HOME>/appsutil/template directory on the database tier. • AutoConfig configuration files, such as httpd.conf, are created as a result of AutoConfig instantiating the corresponding template files. Configuration files contain values corresponding to the settings specified for a particular site. After AutoConfig has been run, numerous configuration files will have been created in various directories. • AutoConfig creates configuration files by reading several different types of file from various locations.

InfraOptimization Net Services Topology Data Model The Net Services Topology Data Model stores the entire topological information about a single Oracle Application instance. The data model stores information about each node in the Oracle Applications instance which is then used to generate the Net Service configuration files (for example tnsnames.ora). AutoConfig seeds the data model with relevant data. The Net Services Topology Data Model stores the following information: On the database tier: Hostname, Database SID, Database Name, Instance Name, TNS Descriptors..... On the application tier: Hostname, FNDFS and FNDSM alias descriptors......... The Net Services Topology Data Model is seeded every time you run AutoConfig on the respective tier. Every time you run AutoConfig on the database tier, the relevant data is seeded/updated for the database tier. Respectively, every time you run AutoConfig on the application tier, the relevant data is seeded/updated for the application tier. To deregister the current application tier from the Net Services Topology Data Model, invoke the following command: $ perl <AD_TOP>/bin/adgentns.pl appspass=<APPSpwd> contextfile=<CONTEXT> -removeserver To deregister the current database tier from the Net Services Topology Data Model, invoke the following command: $ perl <RDBMS ORACLE_HOME>/appsutil/bin/adgentns.pl appspass=< APPSpwd> contextfile=<CONTEXT> - removeserver
Context Files XML based Context Files, uses by Autoconfig, is a Repository of all the installed Configuration Parameters with value: Application Context File and Database Context File, i.e. hundreds of config and env files present in EBS. Run the following script to determine if all context files have been registered in the database. The script should return a run and patch context file for each application server and one for the database server. select path,status,serial_number,version from fnd_oam_context_files where name not in ('TEMPLATE','METADATA') and (status is null or status !='VALID'); If the run file system data is missing from the database simply source the run file system environment and run autoconfig. If the patch file system data (managed servers or context file) is missing from the database then run the following after sourcing the run file system environment.

InfraOptimization Oracle EBS R12.2: Concurrent Processing Server
Concurrent Processing Server Most user interactions with Oracle Applications data are conducted via the HTML interface or the Forms interface. However, some reporting and updating programs may need to be run either periodically or on an ad hoc basis. As these programs may require a large number of computations, they are run in the background at a time, and with a priority, such that the work of interactive users is not impeded. Such programs are run on the Concurrent Processing server. You submit a request to run a concurrent program through an Oracle Applications form. The request inserts a row into a database table, specifying the program to be run. Concurrent managers read the applicable requests in the table and start the relevant concurrent programs. Note: Log and output files from concurrent programs are generated on the Concurrent Processing server. These should be monitored for errors, and archived or deleted when no longer needed. Failure to do so will eventually result in a shortage of disk space. InfraOptimization
Concurrent Manager: Introduction  Batch Processing Sub-System  Programs are run as operating system background processes.  These programs may be written using variety of Oracle tools, programming languages for executables, or OS scripts. The Internal Concurrent Manager (ICM), which functions as the "boss" of all the other managers, i.e. controls all other concurrent managers. It administers the startup and shutdown of managers as defined by their work shift, monitors for process failure, and cleans up if a failure occurs. Warning: You cannot alter the definition of the Internal Concurrent Manager. The Conflict Resolution Manager (CRM) enforces rules designed to ensure that incompatible concurrent requests do not run in the same conflict domain. The Standard Manager as shipped with Oracle Applications will accept and run any concurrent requests. It has no specialization. The Standard manager is active all the time; it works 365 days a year, 24 hours a day. Warning: You should not alter the definition of the Standard concurrent manager. If you do, and you have not defined additional managers to accept your requests, some programs may not run. Use the Standard manager as a safety net, a manager who is always available to run any request. Define additional managers to handle your installation site's specific needs.

Concurrent Request – Lifecycle High Level Phase Activity Pending / Normal The request is waiting to be run Pending / Standby The request is waiting at CRM Running / Normal The request is running Completed / Normal The request has finished Inactive / No Manager The request cannot be run. No manager available to process it.
Concurrent Request – Lifecycle Phase Status Description Pending Normal Request is waiting for the next available manager. Standby Program to run request is incompatible with other program(s) currently running Scheduled Request is scheduled to start at a future time or date Waiting A child request is waiting for its Parent request to mark it ready to run. For example, a report in a report set that runs sequentially must wait for a prior report to complete. Running Normal Request is running normally Paused Parent request pauses for all its child requests to complete. For example, a report set pauses for all reports in the set to complete. Resuming All requests submitted by the same parent request have completed running. The Parent request is waiting to be restarted. Terminating Running request is terminated, by selecting Terminate in the Status field of the Request Details zone. Completed Normal Request completes normally. Error Request failed to complete successfully Warning Request completes with warnings. For example, a report is generated successfully but fails to print. Cancelled Pending or Inactive request is cancelled, by selecting Cancel in the Status field of the Request Details zone. Terminated Running request is terminated, by selecting Terminate in the Status field of the Request Details zone. Inactive Disabled Program to run request is not enabled. Contact your system administrator. On Hold Pending request is placed on hold, by selecting Hold in the Status field of the Request Details zone. No Manager No manager is defined to run the request. Check with your system administrator.

Service Management InfraOptimization With Service Management, the Internal Concurrent Manager (ICM) manages the various service processes across multiple hosts. On each host, a Service Manager acts on behalf of the ICM, allowing the ICM to monitor and control service processes on that host. System administrators can then configure, monitor, and control services though a management console which communicates with the ICM. Service Management provides a fault tolerant system. If a service process exits unexpectedly, the ICM will automatically attempt to restart the process. If a host fails, the ICM may start the affected service processes on a secondary host. The ICM itself is monitored and kept alive by Internal Monitor processes located on various hosts.
InfraOptimization Concurrent Manager: Tuning Consideration • 50%of performance tuning is in the business! – Review long-running auto resubmitted jobs – Review short/long-running jobs – selective parameters? – Don’t purge jobs that the users then have to run again • Points to note – More managers/workers != more throughput (More workers = More accesses) – Avoid enabling an excessive number of managers/workers • New systems: a start point is 1-2 target process per CPU – Balance with resources required by online activity – managers/workers • Carefully consider reducing the CRM sleep time to 5 ~ 10 secs • Set Concurrent: Force Local Output File Mode" to "Yes“ • Set CONC_PMON_METHOD=LOCK
InfraOptimization Concurrent Manager: Enhancing Performance – Best Practice  Tuning Concurrent Queue Parameters • Sleep Seconds  is the number of seconds your Concurrent manager waits between checking the list of pending concurrent requests (concurrent requests waiting to be started). Tips: High number, e.g. 120s avoids constant polls to check for new requests. Low number , e.g. 20s is good enough when number of submitted requests is very high. Note: Concurrent Manager will not sleep at all if there are pending requests. • Cache Size  at least twice the number of target processes. • Process  Increase it if the pending/normal requests are high based on physical server capacity • Purging & Defragmentation associated tables • Gather Schema Statistics  Workload Management • Specialized Concurrent managers  Output Post Processor – OPP • Java Heap Size  Transaction Managers Backend queue concurrent manager details Select rpad(user_concurrent_queue_name ,50,'-') "Queue Name",TARGET_NODE, MAX_PROCESSES,running_processes, nvl(to_char(SLEEP_SECONDS), 'Not Set') Sleep_Second, nvl(to_char(cache_size),'Not Set')Cache_size from FND_CONCURRENT_QUEUES_VL fcq order by 1;
InfraOptimization Concurrent Manager: Tuning Generic Guideline  Throughput To maximize throughput consider reducing the sleep time of the Conflict Resolution Manager (CRM). The default value is 60 seconds. You can consider setting to 5 or 10 seconds. Avoid enabling an excessive number of standard or specialized managers. It can degrade the performance due polling on queue tables (FND_CONCURRENT_REQUESTS...). You need to create specialized managers only if there is a real need.  Avoid enabling an excessive number of standard or specialized managers.

Troubleshooting Concurrent Manager: Enable Tracing Enable Tracing On Program Level System Administrator Responsibility • • Navigation: Concurrent -> Program -> Define Click the “Enable Trace” button Note:- It is not suggested as this generates trace for all the request submitted by all end- users. Hence this could generate lots of trace files which is an additional overhead and degrade performance. Enable Tracing On Request Level (Recommended ) Responsibility: System Administrator Navigate: Profiles > System Query Profile Option “Concurrent: Allow Debugging” Set profile to Yes Logon to the Responsibility that runs the Concurrent Program In the Submit Request Screen click on Debug Options (B) Select the Checkbox for SQL Trace and select desired Trace level. Submit the Request.
InfraOptimization Concurrent Manager: Tuning Options Sleep Seconds • Sleep Seconds - is the number of seconds your Concurrent manager waits between checking the list of pending concurrent requests (concurrent requests waiting to be started). A manager only sleeps if there are no runnable jobs in the queue. Tip: During peak time, when the number of requests submitted is expected to be high, Set the sleep time to a reasonable wait time(e.g. 30 seconds) dependent on the average run time and to prevent backlog. Otherwise set the sleep time to a high number (e.g. 2 minutes) . This avoids constant polls to check for new requests. • If you have multiple manager processes, sleep time is the max time to wait until the new request is picked up from the queue. • e.g. 5 Standard managers, sleep time 60 saeconds = average time to pick up the new request from the queue if all managers are idle: 60/5 = ~12 seconds. • Guideline for tuning: • Set «sleep seconds» = avg requirement * processes * (1 - utilization) • Example 1: Req = 20s, util =20%, proc = 3 – 20 * 3 * (1 - 0.2) = 20 * 3 * .8 = 48 seconds • Example 2: Req = 20s, util =90%, proc = 3 – 20 * 3 * (1 - 0.9) = 20 * 3 * .1 = 6 seconds , less then requirement? The problem is somewhere else!
InfraOptimization Concurrent Manager: Tuning Options Cache size • Cache size = The number of pending requests being fetched for execution from the requests queue • What cache size to choose? • Small cache sizes are better for managers executing long running requests • Small cache sizes are better for managers with lots of processes • Larger cache size is good for managers with few processes executing quick (or both quick and slow) requests • Larger cache size is good if you have a lot of new requests incoming all the time • If at least one request was fetched, the queue will be checked again right after all the cached requests have been processed • This reduces the significance of the cache size • Guideline for tuning: • Increase the cache size (number of requests cached) to at least twice the number of target processes. For example, if a manager's work shift has 1 target process and a cache value of 3, it will read three requests, and try to run those three requests before reading any new requests. Tip: Enter a value of 1 when defining a manager that runs long, time-consuming jobs, and a value of 3 or 4 for managers that run small, quick jobs. This is only guidance and a balance needs to struck in tuning the cache, so with fast jobs you need to cache to get enough work for a few minutes. With slow jobs, a small queue helps should you need to reprioritize requests.

RRA - Report Review Agent (FNDFS ) 1. The Concurrent Processing server communicates with the data server using Oracle Net. 2. The resultant concurrent program log or output file from a request is passed back as a report to the Report Review Agent. 3. The Report Review Agent passes a file containing the entire report to the forms server. 4. The Forms Services component passes the report back to the user’s browser one page at time. Profile options can be used to control the size of the files and pages passed, to suit report volume and available network capacity. InfraOptimization  Online viewing of report log and output files  Viewing of reports one page at a time  Storage of report output on the concurrent processing node The log or output file that results from a concurrent request is sent to a utility known as the Report Review Agent, which passes a file containing the entire report to the Forms services, which passes the report back to the user’s browser one page at a time.
Output Post Processor - OPP Increase Number of OPP processes Increase the number of Threads OR Concurrent Processing uses the Output Post Processor (OPP) to enforce Post Processing actions for concurrent requests. Tip : It is suggested to increase the number of "threads" as far as you can until you start hitting the memory limit. If you still need more throughput, then you can increase "Processes". If you run lots of "Huge Reports" and running into OutOfMemoryError then you can increase the "Processes". The limiting factor with increasing "threads" is memory, if you set the max heap size of a JVM to 2GB, then all "threads" will share this memory. Concurrent -> Manager -> Define > "Output Post Processor" oracle.apps.fnd.cp.opp.OPPServiceThread:2:0:max_threads=5
Output Post Processor - OPP Heap Size To prevent the error "java.lang.OutOfMemoryError: Java heap space“ check the current value : SELECT service_id, service_handle, developer_parameters FROM fnd_cp_services WHERE service_id = (SELECT manager_type FROM fnd_concurrent_queues WHERE concurrent_queue_name = 'FNDCPOPP'); Increase the maximum Java heap size for the OPP to 1024MB ( Max 2GB): UPDATE fnd_cp_services SET developer_parameters = 'J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx1024m' WHERE service_id = (SELECT manager_type FROM fnd_concurrent_queues WHERE concurrent_queue_name = 'FNDCPOPP');
Output Post Processor - OPP InfraOptimization Error The Output Post-processor is running but has not picked up this request. No further attempts will be made to post-process this request, and the request will be marked with Warning status. Action Setting the Profile Option ‘Concurrent: OPP Response Timeout’ to a higher value may be necessary. If the value of the Profile Option ‘Concurrent:OPP Response Timeout’ is 120 then increase it to 240. (Value * 2). Increase the number of processes or threads (or both) .
Output Post Processor - OPP InfraOptimization Error The Concurrent Manager has timed out waiting for the Output Post Processor to finish this Request. Check that there are enough Output Post Processor Service Processes running. More information may be found in the Service Process logfile. Action  Check the Profile Option "Concurrent:OPP Process Timeout".  Increase Increase the setting to a higher value. For example: Set the value to 10800 sec (3 hours).

Database Features Schema product code objects (Packages, Procedures, Functions, Triggers, Views, Materialized views, Java classes, Queues) are stored in the APPS schema, whereas product data objects (Tables, Sequences, Indexes, Constraints, Queues) are stored in the relevant base product schemas, i.e. GL, INV, AP etc. Relationship Between APPS Schema and Base Product Schemas Schemas and Data Access Some views access packages or functions, where the value returned by the package or function may depend on the environment having been set up properly. The environment is initialized automatically when accessing Oracle E-Business Suite through the Sign-On screen, or when using concurrent processing with Oracle Reports or SQL scripts. Consequently, if you connect directly to a schema, the rows returned by the view may be different from those returned when you are running in an Oracle E-Business Suite environment. For example, a view may reference a profile option: when accessed from SQL*Plus, the site value of the profile option will be used, rather than the setting for a particular Oracle E-Business Suite user.
Space Management: Oracle Applications Tablespace Model (OATM) Oracle E-Business Suite Release 12.2 utilizes as standard a modern infrastructure for tablespace management, the Oracle Applications Tablespace Model (OATM). The Oracle Applications Tablespace Model is similar to the traditional model in retaining the system, undo, and temporary tablespaces. The key difference is that Oracle E- Business Suite products in an OATM environment share a much smaller number of tablespaces, rather than having their own dedicated tablespaces. Oracle E-Business Suite schema objects are allocated to the shared tablespaces based on two main factors: the type of data they contain, and I/O characteristics such as size, life span, access methods, and locking granularity. For example, tables that contain seed data are allocated to a different tablespace from the tables that contain transactional data. In addition, while most indexes are held in the same tablespace as the base table, indexes on transaction tables are held in a single tablespace dedicated to such indexes. The Oracle Applications Tablespace Model provides a variety of benefits, which are summarized in the list below:  Simplifies maintenance and recovery by using far fewer tablespaces than the older model.  Uses locally managed tablespaces, whose choice of extent management types (autoallocate or uniform) allows more precise control over unused space and hence can help reduce fragmentation.  Takes advantage of automatic segment space management, eliminating the need for manual space management tasks.  Increases block-packing compared to the older model, reducing the overall number of buffer gets and thereby improving runtime performance.  Makes best use of the restricted number of raw devices available in Oracle Real Applications Cluster (Oracle RAC) and other environments, where every tablespace requires its own raw device.  Maximizes usefulness of wide disk stripe configurations. Oracle E-Business Suite Release 12.2 requires an Oracle database block size of 8K. No other block size may be used.
Oracle Applications Tablespace Model (OATM): Types & Contents Tablespace Type Tablespace Name Contents Transaction Tables APPS_TS_TX_DATA Tables that contain transaction data. Transaction Indexes APPS_TS_TX_IDX Indexes on transaction tables. Reference APPS_TS_SEED Reference and set-up data and indexes. Interface APPS_TS_INTERFACE Interface and temporary data and indexes.

• In 12.2 all patching operations are online by adop utility – EBS will remain available to users during patching operations. In another word, critical business operations were not interrupted by maintenance operations – Downtime Redefined as "Cutover“, which is predictable: The time taken to bounce the Middle Tiers • Online patching uses – EBS Edition Based Redefinition (EBR) – Web Logic Server Online Patching: Copy the Code, NOT the Data • Copy the production code • Apply patches to the copy • EBS uses both the file system and the database to store the code and data that make up the application – Code • Stored both on the File system & In the Database • Any code object changed in a patch is copied – Data • Stored both on the File system & In the Database • Application data is NOT copied by a patch
InfraOptimization Edition-Based Redefinition: The key to Online Application Upgrade and Maintenance The revolutionary new capability is edition-based redefinition:  Code changes are installed in the privacy of a new edition  Data changes are made safely by writing only to new columns or new tables not seen by the old edition. An editioning view exposes a different projection of a table into each edition to allow each to see just its own columns.  A cross-edition trigger propagates data changes made by the old edition into the new edition’s columns, or (in hot-rollover) vice-versa. • Used by Online Users • Never changed by a Patch • Used by the Patching Tools • Changes do no affect the running Application
InfraOptimization AD Online Patching: ADOP Patching Procedures
Adop Phase Scope Prepare Gets patching filesystem ready to apply a patch. Checks that ETCC has been run against the database Oracle Home and that all required patches are applied. synchronize filesystems - If any configuration changes have been made, this will cause the prepare phase to initiate a fs_clone of the current run filesystem to the patch filesystem. run autoconfig if necessary. check tablespaces for sufficient free space before starting. check APPS_FNDFS listener to make sure concurrent requests will launch. launch concurrent request - "Online Patching In Progress" (ADZDPATCH). synchronize snapshots between run and patch filesystems. Apply merging patches - ADOP determines correct options automatically. patch repository location. ADOP log directories. how to run ADOP unattended by passing the required passwords into the ADOP command. how to use adctrl with ADOP. viewing the ADOP patch log file while ADOP is running. Finalize compiles invalids objects in the patch edition. determines DDL statements to execute at cutover. validates that the system is ready for a cutover. gathers statistics for performance. Cutover once started, the abort phase can not be issued. runs the finalize phase if it was missed. cancels concurrent request - "Online Patching In Progress" (ADZDPATCH). shuts down the internal concurrent manager. stops any processes that may have been started on the patch filesystem. stops the RUNNING applications tiers. executes the DDL statements prepared during the finalize phase. loads jar files into the database. synchronizes snapshots between run and patch filesystems. broadcasts a message to local users that a cutover is taking place and to re-source their working environment. Cleanup cleans up old editions explains the three methods of cleanup. QUICK cleanup performs removal of obsolete crossedition triggers and seed data. STANDARD cleanup performs removal of obsolete crossedition triggers and seed data, drops (removes) obsolete editioned code objects (covered objects). (DEFAULT MODE) FULL cleanup performs maximum cleanup, which drops all obsolete code and data from earlier editions

Monitoring: Online Patching Session InfraOptimization
1. Way of knowing history of online patching select adop_session_id,prepare_status,apply_status,finalize_status,cutover_status,cleanup_status,abort_status,status,abandon_flag,node_name from ad_adop_sessions order by adop_session_id; Note: Y denotes that the phase is done N denotes that the phase has not been completed X denotes that the phase is not applicable R denotes that the phase is running (in progress) F denotes that the phase has failed P (is applicable only to APPLY phase) denotes at least one patch is already applied for the session id C denotes that the status of this ADOP session has completed Note: Numerical statuses are only relevant for the cutover phase... These status values are updated when a step has completed, and are as follows: N denotes that the phase has not been completed 0 denotes that cutover/force_shutdown has started 1 denotes the "force_shutdown" step has successfully executed 3 denotes the "db_cutover" step has successfully executed 4 denotes the "fs_cutover" step has successfully executed 6 denotes the "force_startup" step has successfully executed Y denotes that the phase is done cutover statuses cutover_status='Y' 'COMPLETED' cutover_status not in ('N','Y','X') and status='F' 'FAILED' cutover_status='0' 'CUTOVER STARTED' cutover_status='1' 'SERVICES SHUTDOWN COMPLETED' cutover_status='3' 'DB CUTOVER COMPLETED' cutover_status='D' 'FLIP SNAPSHOTS COMPLETED' cutover_status='4' 'FS CUTOVER COMPLETED' cutover_status='5' 'ADMIN STARTUP COMPLETED' cutover_status='6' 'SERVICES STARTUP COMPLETED' cutover_status='N' 'NOT STARTED' cutover_status='X' 'NOT APPLICABLE'
2. Check the current status of the adop cycle adop –status usage adop -status generates a summary report adop -status <sessionID> generates a summary report for that session ID adop -status -detail generates a detailed report 3. Way of finding issues on different adop phases sqlplus <apps_schema_name>/<apps_Schema_password> @$AD_TOP/sql/ADZDSHOWLOG.sql  adzdshowlog.out file generated select * from ad_zd_logs order by log_sequence desc; 4. Way of knowing the enabling problem @$AD_TOP/sql/ADZDSHOWDDLS.sql select count(1) from ad_zd_logs;  If the count is increasing then enablement is progressing.
5. Way of knowing which patches were applied in each ADOP_SESSION_ID (patching cycle) select * from ad_adop_session_patches order by end_date desc; or set pagesize 200; set linesize 160; column adop_session_id format 999999999999; column bug_number format a15; column status format a15; column applied_file_system_base format a23; column patch_file_system_base format a23; column adpatch_options format a15; column node_name format a15; column end_date format a15; column clone_status format a15; select adop_session_id, bug_number, status, applied_file_system_base, patch_file_system_base, adpatch_options, node_name, end_date, clone_status from ad_adop_session_patches order by end_date desc; Note: STATUS N - Not Applied In the current node but applied in other nodes R - Patch Application is going on. H - Patch failed in the middle. (Hard Failure) F - Patch failed in the middle but user tried to skip some failures. S - Patch Application succeeded after skipping the failed jobs. Y - Patch Application succeeded. C - Reserved for clone and config_clone. Indicates clone completed select ADOP_SESSION_ID,BUG_NUMBER,CLONE_STATUS,STATUS,NODE_NAME from AD_ADOP_SESSION_PATCHES order by ADOP_SESSION_ID;
6. Log File for Errors $COMMON_TOP/clone/FMW/logs/CLONE<timestamp>.error $COMMON_TOP/clone/FMW/logs/CLONE<timestamp>.log $INST_TOP/admin/log/clone directory $APPLRGF/TXK/ohsCloneLog ( this captures cloning failures for OHS ) 7. Ensure the following RUN and PATCH file system ORACLE_HOME(s) are registered in the inventory.xml - 10.1.2 Oracle Home - Oracle_EBS-app1 Oracle Home - webtier Oracle Home - oracle_common Oracle Home more …/ContentsXML/inventory.xml |grep LOC 8. Confirm that the FND_OAM_CONTEXT_FILES table now holds the correct data Run the following script to determine if all context files have been registered in the database. The script should return a run and patch context file for each application server and one for the database server. select path,status,serial_number,version from fnd_oam_context_files where name not in ('TEMPLATE','METADATA') and (status is null or status !='VALID'); InfraOptimization
Run the following script to determine the number/types of managed servers registered in the run and patch file systems. The script should return an equal number of managed servers between the run and patch file systems SELECT extractValue(XMLType(TEXT),'//host[@oa_var="s_hostname"]'), extractValue(XMLType(TEXT),'//oacore_server_ports'), extractValue(XMLType(TEXT),'//forms_server_ports'), extractValue(XMLType(TEXT),'//oafm_server_ports'), extractValue(XMLType(TEXT),'//forms-c4ws_server_ports'), extractValue(XMLType(TEXT),'//oaea_server_ports') from fnd_oam_context_files where name not in ('TEMPLATE','METADATA') and (status is null or status !='H') and EXTRACTVALUE(XMLType(TEXT),'//file_edition_type')='run' and CTX_TYPE = 'A'; SELECT extractValue(XMLType(TEXT),'//host[@oa_var="s_hostname"]'), extractValue(XMLType(TEXT),'//oacore_server_ports'), extractValue(XMLType(TEXT),'//forms_server_ports'), extractValue(XMLType(TEXT),'//oafm_server_ports'), extractValue(XMLType(TEXT),'//forms-c4ws_server_ports'), extractValue(XMLType(TEXT),'//oaea_server_ports') from fnd_oam_context_files where name not in ('TEMPLATE','METADATA') and (status is null or status !='H') and EXTRACTVALUE(XMLType(TEXT),'//file_edition_type')='patch' and CTX_TYPE = 'A'; InfraOptimization

    A Tier isa logical grouping of services, potentially spread across more than one physical machine. The three-tier architecture that comprises an Oracle E-Business Suite installation is made up of the database tier, which supports and manages the Oracle database; the application tier, which supports and manages the various Oracle E-Business Suite components, and is sometimes known as the middle tier; and the desktop tier, which provides the user interface via an add-on component to a standard web browser. Application Tier Services Root services, Web Entry Point services, Web Application services, Batch Processing services, Other services A Node is a logical set of processes running on one hardware machine. Sometimes a node is also referred to as a "server" or an "instance". In a single-node installation of Oracle E-Business Suite, all the Applications processes (including the database processes) run on one node, whereas in a multi-node installation, the processes are distributed across multiple nodes. For example, Node 1 : DB 11.2.0.3, Node 2: Web and forms, Node 3 : concurrent manager. A multi-node installation of Release 12 supports both shared and non-shared application tier file systems. A Service is a functional set of Oracle E-Business Suite application processes running on one or more nodes. Where applicable, the term 'service' is replacing the more traditional term of 'server'. For example, Web services process HTTP requests, and Forms services process requests for activities related to Oracle Forms. The Concurrent Processing server supports data-intensive programs that run in the background.

    Understanding Three‐tier TechnicalArchitecture: EBS R12.2 Three-Tier Architecture Perspective EBS R12.2 Technology Architecture Desktop or Client Tier - provides the user interface using a web browser to access the applications. Application Tier - The application tier, sometimes referred to as the middle tier, hosts the various services and servers that implement and execute the business logic, and mediates communications between the desktop tier and the database tier. Database Tier - supports the Oracle RDBMS and is the main data storage area. The database server does not communicate directly with desktop clients

Most HTTP configuration is managed via native Oracle WebLogic Server tools, Fusion Middleware Control, or manually editing of the configuration files. Only a limited set of HTTP configuration files are maintained via AutoConfig. Fusion Middleware Control Configuration of oacore, oafm, forms and forms-c4ws services Properties for the oacore, oafm, forms and forms- c4ws services, including the classpath and JVM arguments, need to be updated through native WebLogic tools such as WebLogic Administration Console.

WebLogic Server Admin Console Managing JVM instances of the oacore, oafm, forms and forms-c4ws services. Each JVM instance of a service corresponds to a managed server of that service type. The number of instances needs to be controlled by explicitly creating or deleting managed servers for the service.

($FMW_Home/webtier/instances/EBS_web_<instance_name>_OHS1/config/OHS/E BS_web_<instance_name>/httpd.conf)  When the configuration of OHS is for a resource that needs to be processed by Java, such as logging into EBS, the OHS configuration will redirect the request to the Web Logic Server (WLS) Java process (OACore in this case).  WLS determines the J2EE application that should deal with the request, which is called "oacore".  This J2EE application needs to be deployed and available for processing requests in order for the request to succeed. The J2EE application needs to access a database and does this via a datasource which is configured within WLS. All code must access the data model via the APPS synonym!

    InfraOptimization AutoConfig Instantiation Mechanism AutoConfigOperation • AutoConfig template files are used as the starting point for creating site-specific configuration files. AutoConfig evaluates the context variables in a template file, determines the actual values required, and creates a configuration file with these values substituted. This process, described in more detail later in this chapter, is called instantiation. There is one template file for each configuration file. Template files are located in the various <PROD>_TOP/admin/template directories on the application tier, and in the <RDBMS_ORACLE_HOME>/appsutil/template directory on the database tier. • AutoConfig driver files are used to list the corresponding template files and locations, and specify the commands to be executed. For example, the commands might update profile options. Driver files are located in each <PROD>_TOP/admin/driver directory on the application tier, and in the <RDBMS_ORACLE_HOME>/appsutil/template directory on the database tier. • AutoConfig configuration files, such as httpd.conf, are created as a result of AutoConfig instantiating the corresponding template files. Configuration files contain values corresponding to the settings specified for a particular site. After AutoConfig has been run, numerous configuration files will have been created in various directories. • AutoConfig creates configuration files by reading several different types of file from various locations.

    InfraOptimization Net Services TopologyData Model The Net Services Topology Data Model stores the entire topological information about a single Oracle Application instance. The data model stores information about each node in the Oracle Applications instance which is then used to generate the Net Service configuration files (for example tnsnames.ora). AutoConfig seeds the data model with relevant data. The Net Services Topology Data Model stores the following information: On the database tier: Hostname, Database SID, Database Name, Instance Name, TNS Descriptors..... On the application tier: Hostname, FNDFS and FNDSM alias descriptors......... The Net Services Topology Data Model is seeded every time you run AutoConfig on the respective tier. Every time you run AutoConfig on the database tier, the relevant data is seeded/updated for the database tier. Respectively, every time you run AutoConfig on the application tier, the relevant data is seeded/updated for the application tier. To deregister the current application tier from the Net Services Topology Data Model, invoke the following command: $ perl <AD_TOP>/bin/adgentns.pl appspass=<APPSpwd> contextfile=<CONTEXT> -removeserver To deregister the current database tier from the Net Services Topology Data Model, invoke the following command: $ perl <RDBMS ORACLE_HOME>/appsutil/bin/adgentns.pl appspass=< APPSpwd> contextfile=<CONTEXT> - removeserver

    Concurrent Processing Server Mostuser interactions with Oracle Applications data are conducted via the HTML interface or the Forms interface. However, some reporting and updating programs may need to be run either periodically or on an ad hoc basis. As these programs may require a large number of computations, they are run in the background at a time, and with a priority, such that the work of interactive users is not impeded. Such programs are run on the Concurrent Processing server. You submit a request to run a concurrent program through an Oracle Applications form. The request inserts a row into a database table, specifying the program to be run. Concurrent managers read the applicable requests in the table and start the relevant concurrent programs. Note: Log and output files from concurrent programs are generated on the Concurrent Processing server. These should be monitored for errors, and archived or deleted when no longer needed. Failure to do so will eventually result in a shortage of disk space. InfraOptimization

    Concurrent Manager: Introduction  BatchProcessing Sub-System  Programs are run as operating system background processes.  These programs may be written using variety of Oracle tools, programming languages for executables, or OS scripts. The Internal Concurrent Manager (ICM), which functions as the "boss" of all the other managers, i.e. controls all other concurrent managers. It administers the startup and shutdown of managers as defined by their work shift, monitors for process failure, and cleans up if a failure occurs. Warning: You cannot alter the definition of the Internal Concurrent Manager. The Conflict Resolution Manager (CRM) enforces rules designed to ensure that incompatible concurrent requests do not run in the same conflict domain. The Standard Manager as shipped with Oracle Applications will accept and run any concurrent requests. It has no specialization. The Standard manager is active all the time; it works 365 days a year, 24 hours a day. Warning: You should not alter the definition of the Standard concurrent manager. If you do, and you have not defined additional managers to accept your requests, some programs may not run. Use the Standard manager as a safety net, a manager who is always available to run any request. Define additional managers to handle your installation site's specific needs.

    Service Management InfraOptimization With ServiceManagement, the Internal Concurrent Manager (ICM) manages the various service processes across multiple hosts. On each host, a Service Manager acts on behalf of the ICM, allowing the ICM to monitor and control service processes on that host. System administrators can then configure, monitor, and control services though a management console which communicates with the ICM. Service Management provides a fault tolerant system. If a service process exits unexpectedly, the ICM will automatically attempt to restart the process. If a host fails, the ICM may start the affected service processes on a secondary host. The ICM itself is monitored and kept alive by Internal Monitor processes located on various hosts.

    InfraOptimization Concurrent Manager: Tuning Options SleepSeconds • Sleep Seconds - is the number of seconds your Concurrent manager waits between checking the list of pending concurrent requests (concurrent requests waiting to be started). A manager only sleeps if there are no runnable jobs in the queue. Tip: During peak time, when the number of requests submitted is expected to be high, Set the sleep time to a reasonable wait time(e.g. 30 seconds) dependent on the average run time and to prevent backlog. Otherwise set the sleep time to a high number (e.g. 2 minutes) . This avoids constant polls to check for new requests. • If you have multiple manager processes, sleep time is the max time to wait until the new request is picked up from the queue. • e.g. 5 Standard managers, sleep time 60 saeconds = average time to pick up the new request from the queue if all managers are idle: 60/5 = ~12 seconds. • Guideline for tuning: • Set «sleep seconds» = avg requirement * processes * (1 - utilization) • Example 1: Req = 20s, util =20%, proc = 3 – 20 * 3 * (1 - 0.2) = 20 * 3 * .8 = 48 seconds • Example 2: Req = 20s, util =90%, proc = 3 – 20 * 3 * (1 - 0.9) = 20 * 3 * .1 = 6 seconds , less then requirement? The problem is somewhere else!
  • 95.
    InfraOptimization Concurrent Manager: Tuning Options Cachesize • Cache size = The number of pending requests being fetched for execution from the requests queue • What cache size to choose? • Small cache sizes are better for managers executing long running requests • Small cache sizes are better for managers with lots of processes • Larger cache size is good for managers with few processes executing quick (or both quick and slow) requests • Larger cache size is good if you have a lot of new requests incoming all the time • If at least one request was fetched, the queue will be checked again right after all the cached requests have been processed • This reduces the significance of the cache size • Guideline for tuning: • Increase the cache size (number of requests cached) to at least twice the number of target processes. For example, if a manager's work shift has 1 target process and a cache value of 3, it will read three requests, and try to run those three requests before reading any new requests. Tip: Enter a value of 1 when defining a manager that runs long, time-consuming jobs, and a value of 3 or 4 for managers that run small, quick jobs. This is only guidance and a balance needs to struck in tuning the cache, so with fast jobs you need to cache to get enough work for a few minutes. With slow jobs, a small queue helps should you need to reprioritize requests.

    RRA - ReportReview Agent (FNDFS ) 1. The Concurrent Processing server communicates with the data server using Oracle Net. 2. The resultant concurrent program log or output file from a request is passed back as a report to the Report Review Agent. 3. The Report Review Agent passes a file containing the entire report to the forms server. 4. The Forms Services component passes the report back to the user’s browser one page at time. Profile options can be used to control the size of the files and pages passed, to suit report volume and available network capacity. InfraOptimization  Online viewing of report log and output files  Viewing of reports one page at a time  Storage of report output on the concurrent processing node The log or output file that results from a concurrent request is sent to a utility known as the Report Review Agent, which passes a file containing the entire report to the Forms services, which passes the report back to the user’s browser one page at a time.

    Output Post Processor- OPP Increase Number of OPP processes Increase the number of Threads OR Concurrent Processing uses the Output Post Processor (OPP) to enforce Post Processing actions for concurrent requests. Tip : It is suggested to increase the number of "threads" as far as you can until you start hitting the memory limit. If you still need more throughput, then you can increase "Processes". If you run lots of "Huge Reports" and running into OutOfMemoryError then you can increase the "Processes". The limiting factor with increasing "threads" is memory, if you set the max heap size of a JVM to 2GB, then all "threads" will share this memory.

    Database Features Schema product codeobjects (Packages, Procedures, Functions, Triggers, Views, Materialized views, Java classes, Queues) are stored in the APPS schema, whereas product data objects (Tables, Sequences, Indexes, Constraints, Queues) are stored in the relevant base product schemas, i.e. GL, INV, AP etc. Relationship Between APPS Schema and Base Product Schemas Schemas and Data Access Some views access packages or functions, where the value returned by the package or function may depend on the environment having been set up properly. The environment is initialized automatically when accessing Oracle E-Business Suite through the Sign-On screen, or when using concurrent processing with Oracle Reports or SQL scripts. Consequently, if you connect directly to a schema, the rows returned by the view may be different from those returned when you are running in an Oracle E-Business Suite environment. For example, a view may reference a profile option: when accessed from SQL*Plus, the site value of the profile option will be used, rather than the setting for a particular Oracle E-Business Suite user.

    Space Management: Oracle ApplicationsTablespace Model (OATM) Oracle E-Business Suite Release 12.2 utilizes as standard a modern infrastructure for tablespace management, the Oracle Applications Tablespace Model (OATM). The Oracle Applications Tablespace Model is similar to the traditional model in retaining the system, undo, and temporary tablespaces. The key difference is that Oracle E- Business Suite products in an OATM environment share a much smaller number of tablespaces, rather than having their own dedicated tablespaces. Oracle E-Business Suite schema objects are allocated to the shared tablespaces based on two main factors: the type of data they contain, and I/O characteristics such as size, life span, access methods, and locking granularity. For example, tables that contain seed data are allocated to a different tablespace from the tables that contain transactional data. In addition, while most indexes are held in the same tablespace as the base table, indexes on transaction tables are held in a single tablespace dedicated to such indexes. The Oracle Applications Tablespace Model provides a variety of benefits, which are summarized in the list below:  Simplifies maintenance and recovery by using far fewer tablespaces than the older model.  Uses locally managed tablespaces, whose choice of extent management types (autoallocate or uniform) allows more precise control over unused space and hence can help reduce fragmentation.  Takes advantage of automatic segment space management, eliminating the need for manual space management tasks.  Increases block-packing compared to the older model, reducing the overall number of buffer gets and thereby improving runtime performance.  Makes best use of the restricted number of raw devices available in Oracle Real Applications Cluster (Oracle RAC) and other environments, where every tablespace requires its own raw device.  Maximizes usefulness of wide disk stripe configurations. Oracle E-Business Suite Release 12.2 requires an Oracle database block size of 8K. No other block size may be used.

    InfraOptimization Edition-Based Redefinition: The keyto Online Application Upgrade and Maintenance The revolutionary new capability is edition-based redefinition:  Code changes are installed in the privacy of a new edition  Data changes are made safely by writing only to new columns or new tables not seen by the old edition. An editioning view exposes a different projection of a table into each edition to allow each to see just its own columns.  A cross-edition trigger propagates data changes made by the old edition into the new edition’s columns, or (in hot-rollover) vice-versa. • Used by Online Users • Never changed by a Patch • Used by the Patching Tools • Changes do no affect the running Application

    Adop Phase Scope Prepare Getspatching filesystem ready to apply a patch. Checks that ETCC has been run against the database Oracle Home and that all required patches are applied. synchronize filesystems - If any configuration changes have been made, this will cause the prepare phase to initiate a fs_clone of the current run filesystem to the patch filesystem. run autoconfig if necessary. check tablespaces for sufficient free space before starting. check APPS_FNDFS listener to make sure concurrent requests will launch. launch concurrent request - "Online Patching In Progress" (ADZDPATCH). synchronize snapshots between run and patch filesystems. Apply merging patches - ADOP determines correct options automatically. patch repository location. ADOP log directories. how to run ADOP unattended by passing the required passwords into the ADOP command. how to use adctrl with ADOP. viewing the ADOP patch log file while ADOP is running. Finalize compiles invalids objects in the patch edition. determines DDL statements to execute at cutover. validates that the system is ready for a cutover. gathers statistics for performance. Cutover once started, the abort phase can not be issued. runs the finalize phase if it was missed. cancels concurrent request - "Online Patching In Progress" (ADZDPATCH). shuts down the internal concurrent manager. stops any processes that may have been started on the patch filesystem. stops the RUNNING applications tiers. executes the DDL statements prepared during the finalize phase. loads jar files into the database. synchronizes snapshots between run and patch filesystems. broadcasts a message to local users that a cutover is taking place and to re-source their working environment. Cleanup cleans up old editions explains the three methods of cleanup. QUICK cleanup performs removal of obsolete crossedition triggers and seed data. STANDARD cleanup performs removal of obsolete crossedition triggers and seed data, drops (removes) obsolete editioned code objects (covered objects). (DEFAULT MODE) FULL cleanup performs maximum cleanup, which drops all obsolete code and data from earlier editions
