• Dual File System (Run Edition File System and Patch Edition File System).
• Patches are applied to Patch Edition File System (copy of Production
System)
• Downtime limited to short ‘Cutover’.
– Cutover is the time taken to switch users from the production system to the newly
patched copy.
– Measured in minutes not in hours/days.
• Changing the Patching Paradigm (downtime patching vs online patching).

R12.2 Environment Overview
• New script to setup the environment: EBSapps.env RUN | PATCH
• New environment variables for R12.2 to help you navigate the system
$FILE_EDITION - Current fs edition type sourced, values: run or patch
$RUN_BASE - RUN file system base directory
$PATCH_BASE - PATCH file system base directory
$NE_BASE - Non-edition file system base directory
$APPL_TOP_NE - Application top that stores product files considered data
$PATCH_TOP – Directory where the patch files are unzipped
– On a multi-node system with non-shared file systems, you must copy the patch files to each
separate $PATCH_TOP directory, so that the patch files are available from the same location on all
nodes
Working with the 12.2 Environment

File Systems Patching Cycle
• Two complete file systems are always present
– Run Edition - Used by the running Application
– Patch Edition - Either:
• Currently being patched
or
• Waiting for the next patching cycle
– The two files systems are rotated between Run and
Patch during every patch cycle

File System Synchronization
• Two file synchronization options
– Patch (driver files from previous patching cycle are reapplied )
– File (only files changed in previous patching cycle are synchronized)
• File based provides a significant performance improvement in adop Prepare phase
– Configurable callout to file system synchronization logic
– Example implementation provided using unix rsync command
– Customer can replace command with smart/advanced disk utility of their choice
• Automatic support for customizations (with ‘sync_mode=delta’)
– All files in the Applications file system are synchronized
– Customizations no longer need to be registered in the custom synchronization driver (adop_sync.drv)
15
Efficient File Based Synchronization*
* Available in AD/TXK Delta 8 and above

File System Synchronization
• New prepare phase parameter (sync_mode) to control synchronization
behaviour
– adop phase=prepare sync_mode=patch (default)
– adop phase=prepare sync_mode=delta (new file based)
• Delta style synchronization uses the file system synchronization command
specified in:
$AD_TOP/patch/115/etc/delta_sync_drv.txt
• Only files changed in the previous patching cycle are synchronized
16

Database Edition-Based Redefinition
17

11gR2 Edition-Based Redefinition (EBR)
• Key enabling technology for Online Patching
– Enables the online upgrade of the application definition
– Allows an application to efficiently store multiple copies of its code and schema in the
same database
• Provides an isolation mechanism that allows pre-upgrade and post-upgrade
schemas to co-exist
– Changes to database objects are made in the isolation of an “Edition”
– Changes to database objects do not affect the running application
18

Online Patching is Enabled by 11gR2 Edition-Based
Redefinition
• Client code connects to an “edition”
of the database
– Run Edition
• Used by online users
• Never changed by a patch
– Patch Edition
• Used by patching tools
• Changes do not affect the running application
• Patch Edition becomes the
Run Edition at Cutover
19

Seed Data Management
20

Seed Data Management
• Seed data is data stored in database tables that affects the behavior of the
application and is patched by EBS development
• In order to patch seed data without disturbing the running application, we
enhance seed data tables to support Editioned Data Storage
– The ability to store multiple editions (copies) of seed data in the same table
• AD/TXK Delta 7
– Full synchronization and cleanup of all rows in seed data table
• AD/TXK Delta 8 and above
– Only rows changed in the last patching cycle are synchronized
21

Incremental Seed Data Synchronization*
• Significant performance improvement in adop Apply phase
– Only rows changed since the last synchronization are updated
– The time taken to synchronize seed data is proportional to the number of rows changed
since the last synchronization
– Minor changes no longer incur the cost of full data replication
• Dual rowset seed data synchronization
– Two permanent sets of seed data
– Only rows changed by a patch are synchronized on prepare
– No cleanup required
22
* Available in AD/TXK Delta.8 and above

12.2 Online Patching Cycle
23

Understanding the Online Patching Cycle
24
• Online Patching is used to apply all patches in 12.2
• Online Patching cycle includes 5 major phases
• New patching tool “adop” orchestrates the patching cycle

Online Patching Cycle – Prepare Phase
• The Basics CleanupCutoverFinalizeApply
• Copy the
production
application code
• Create a new
Patch Edition in
the database
Prepare
Users Online Users OnlineUsers Offline
Prepare
• Synchronizes Patch Edition and Run Edition on the file system
• Create a new Patch Edition in the database

Copyright © 2017, Oracle and/or its affiliates. All rights reserved. | Confidential – Oracle Internal 26
Preparing the File System
• Patch Edition & Run Edition of the file systems
are synchronized
• All files on the Patch Edition are an exact copy
of the files on the Run Edition
• Incremental synchronization is the default
– File based
• All changed files are synchronized
– Patch based
• Patches applied on last cycle are reapplied
• Full synchronization available if necessary

Copyright © 2017, Oracle and/or its affiliates. All rights reserved. | Confidential – Oracle Internal 27
Preparing the Database
• Patch Edition is created in the database
• All code objects in the Patch Edition begin as
pointers to code objects in the Run Edition
• Efficient use of space
– Objects are only “Actualized” into the Patch Edition when a
new revision of the code is applied
• Storage objects such as tables are not copied
– New patching standards are followed for upgrading
storage objects

28
adop phase=prepare
• Validates system configuration to ensure
that the system is ready to start an Online
Patching cycle.
• Check whether to perform cleanup;
execute if needed.
• Prepare is run on all nodes in a muti-node
configuration
• Synchronizes the Run and Patch File System
• Creates the Database Patch Edition
What to Know
• Creates Patch Service and Checks the
integrity of the database data dictionary.
• Checks and submits "Online Patching In
Progress" (ADZDPATCH) concurrent
program.
• Check to see if Oracle E-Business Suite
Technology Codelevel Checker (ETCC) has
has been run.

Cutover

• During cutover a brief downtime is taken
–Middle tier services are stopped and users are logged off the system
–The Patch file system is promoted to be the Run file system
–The Patch database edition is promoted to be the Run database edition
–Perform final maintenance operations
–Middle tier services are restarted
–Users are brought back online on the patched system
• The database does NOT need to be and should not be bounced
during cutover
35

Cutover Automatically Manages all Services on all Nodes
• Middle-tier processes stopped
– Manages all nodes in the configuration
via remote execution
– End Users are disconnected
• File system roles swapped
– Patched (FS-2) promoted to Run
– FS-1 available for next patching cycle
• Database Patch Edition promoted to
Run Edition
• Middle-tier processes restarted
– Manages all nodes in the configuration
via remote execution
– Users reconnect

37
• Brief Downtime
– Application tier services are automatically shut down and
restarted on all nodes
• You must ensure that no users remain on the system
during cutover
– Any third-party processes connected to the old run edition of
the database should be shut down, otherwise they will be
terminated automatically
• Cutover will take longer if it has to wait for long-running
concurrent processes to complete
– If you do not want to wait for in-progress concurrent
requests to finish normally, you can terminate the internal
concurrent manager by executing the ‘adcmctl.sh abort’
command from a different shell.
What to Know
• Before running the cutover command, ensure you are
ready to commit to application of the selected patches.
Once cutover is complete, it is not possible to revert to
the previous edition.
• Execute adop cutover on the primary node
$ adop phase=cutover
What to do

38
Deferring Application Tier Restart
• In some cases, you may need to perform
additional manual steps after cutover but
before restarting the application tier
services
– Apply customizations
– Patch the database tier
• You must start the application tier services
manually after performing additional steps
What to Know
without starting the application services

– Code objects patched in the latest patching cycle are
deleted from Old Editions
– Once all code objects are deleted from an Old Edition it is
also deleted (if cleanup run post actualize_all).

41
• Users are online during the cleanup process
• Removes obsolete objects from the system to
recover space
• If you fail to run the cleanup phase explicitly, it will
be run automatically on the next prepare cycle
– This will cause a delay in starting your next online patching
cycle
• Three cleanup_mode are available
– quick - Performs only essential cleanup tasks
– standard (default) - Removes obsolete code objects

Online Patching Cycle – Special Operations
43

Online Patching Cycle - fs_clone
44
Re-Cloning the Patch Edition File System
• Patch file system is normally incrementally synchronized with
the run edition file system during prepare
• In some special cases a full re-clone of Patch Edition FS is
required when
– The previous Online Patching cycle was aborted
– Manual changes were made to the run edition file system
– Middle-tier technology components were patched
• A full re-clone of Patch Edition FS is recommended
– After applying a large EBS RUP; EBS upgrade to 12.2 RUP.
• Re-cloning the patch edition file system
– Ensures that the files systems are correctly synchronized
– Minimizes any synchronization delay that would normally occur on the
next prepare
• Cannot be executed when there is an active Online Patching
cycle
What to Know
• Must be invoked from the run file system, before the next
prepare phase is run.
• Execute re-clone on the primary node
$ adop phase=fs_clone
What to Do

Online Patching Cycle - Abort
• The Online Patching Cycle can be aborted at any time prior to
Cutover

adop phase=abort
46
• The abort phase is used to terminate a patching cycle
before it is complete and rollback any changes that
have been made.
• Aborts the online patching cycle by dropping the
database patch edition.
• Confirms that there is an in-progress online patching
cycle, so the abort call is therefore valid.
• Cancels the ADZDPATCH concurrent program, if it is
running.

Online Patching Cycle - Abort
47
• Useful when an Online Patching cycle encounters
problems that cannot be fixed immediately
• Returns the system to normal runtime operation
• Online Patching cycle cannot be aborted after
cutover
• Requires a full cleanup and fs_clone before the
next patching cycle to remove the effects of the
failed cycle
• If a full cleanup & fs_clone are not run explicitly,
they will be run automatically by the next prepare
– This will cause a delay during the prepare phase of the next
online patching cycle
What to Know
• Execute adop abort on the primary node
$ adop phase=abort
What to Do

Online Patching Cycle – actualize_all
Confidential – Oracle Internal 48
Full Cleanup as a Periodic Maintenance Operation
• As each Online Patching cycle is completed, the
database will accumulate an additional old
database edition.
• When the number of database editions reaches 25
or more, you should consider running a special
maintenance operation to remove old database
editions
• Actualize all is a special adop phase that ensures
every database editioned object has a version in the
PATCH edition
– This allows all copies in OLD editions to be removed by
full cleanup
What to Know
• Before starting, you should ensure that the system has
the recommended database patches and latest AD-TXK
code level installed.
• Execute adop on the primary node to actualize all
objects and perform a full cleanup
$ adop phase=prepare
$ adop phase=actualize_all
What to do

Online Patching Cycle - Actualize All
49
Full Cleanup Combined with a Scheduled Online Patching Cycle
• The actualize all and full cleanup can also be
executed in conjunction with an Online Patching
cycle
• This maintenance operations will take much longer
than a typical Online Patching cycle and should only
be performed when there is no immediate need to
start or complete a patching cycle
What to Know
• Execute adop on the primary node to actualize all
objects and perform a full cleanup
$ adop phase=apply patches=12345,67890
$ adop phase=actualize_all
What to do

Single File System and Downtime Patching Mode
• Designed for building & testing custom code
– Patches should always be tested on a standard dual file system test instance
before being applied to production.
• Single file system
– Patch file system is not present
– All patches must be applied to the RUN edition using adop apply in downtime mode
• Limited adop phases and modes supported
– Apply phase in downtime mode: Applies patches directly to the RUN edition of the instance.
• Downtime mode should not be used unless directed in the README of the patch.
– Cleanup phase.
50
Designed for Development Instances Only

Applying Downtime Mode Patches on a Single File System
51
Designed for Development Instances Only
• Only supported on development systems
to test custom code
– The code should then always be tested in a standard dual file system
test environment before being applied to production.
• Patches are applied to the RUN edition
of the file system and database
• Oracle does not test patches in Downtime
mode unless explicitly stated in README.
• All application tier services must be down
before applying a patch in Downtime
mode.
What to Know
• Single file system environment must have a
single-node application tier: multi-node
application tiers are not supported.
• Single file system environment can only be
created by conversion from an existing dual
file system environment.
• You cannot convert a single file system
environment back to a dual file system.
• You cannot clone from a single file system
environment.
