  1. 1. SAP HANA SPS 08 - What’s New? Administration & Monitoring SAP HANA Product Management May, 2014 (Delta from SPS 07 to SPS 08)
  2. 2. © 2014 SAP AG. All rights reserved. 2Public Content This presentation provides an overview of the changes regarding administration, monitoring and supportability of the SAP HANA database between the SPS 07 version and the SPS 08 version. It covers changes to the SAP HANA studio administration perspective and changes to the SAP HANA database. Functionality of other SAP HANA studio perspectives (like the SAP HANA Modeler) is not covered in this presentation.
  3. 3. © 2014 SAP AG. All rights reserved. 3Public Agenda Improved Monitoring and Supportability  New monitoring overview: SAPUI5 based dashboard  Improved diagnosis information for blocking situations  New options to collect diagnosis information  Improved resource monitoring  Improved statement analysis  More safety for production systems: warnings are displayed, when data is to be changed  Improved usability  Statistics service enhancements  SLD extension
  4. 4. © 2014 SAP AG. All rights reserved. 4Public Agenda Additional Features  Support for planning engine views/models  Import of geospatial information (shapefiles)  Extended system replication configuration  New/enhanced monitoring views
  5. 5. Improved Monitoring and Supportability
  6. 6. © 2014 SAP AG. All rights reserved. 6Public Improved Monitoring and Supportability New Monitoring Dashboard New SAPUI5 Based Monitoring Dashboard  Web-browser-based dashboard that visualizes key aspects of system health and configuration, for example: – Current high and medium priority alerts – Memory and CPU usage – Availability of data backups  Drill down to views containing more detailed information  Role sap.hana.admin.roles::Monitoring is required, which is not granted by default to the standard MONITORING role
  7. 7. © 2014 SAP AG. All rights reserved. 7Public HANA Improved Monitoring and Supportability Improved Diagnosis Information for Blocking Situations Emergency Support Mode  SAP HANA studio collects information about systems using SQL  When a system cannot be reached by SQL or it is experiencing major performance issues due to high load or blocking situations, information can instead be collected using the connection of the SAP start service (sapstartsrv).  The Administration editor diagnosis mode provides access to: – The operational status of all services in the system – Log and trace files – The collection of diagnosis information into a zip file – All connections, transactions, blocked transactions, and threads in the system  If necessary, you can cancel individual connections and transactions, or even cancel all transactions. sapstartsrv python Indexserver hdbcons
  8. 8. © 2014 SAP AG. All rights reserved. 8Public Improved Monitoring and Supportability Improved Diagnosis Information for Blocking Situations Improved Information for Cancel Status  System view M_CONNECTIONS, column CONNECTION_STATUS shows if the cancellation of a connection has been requested and if the cancellation is already ongoing.  The following values are possible: – IDLE (CANCEL REQUESTED) The connection is idle, a cancellation has been requested, but the connection is not yet canceling – RUNNING (CANCEL REQUESTED) The connection is working on a request, a cancellation has been requested, but the connection is not yet canceling (meaning not in rollback yet) – RUNNING (CANCELING) The connection is working on a request, a cancellation has been requested, and the connection is already canceling (meaning already in rollback)
  9. 9. © 2014 SAP AG. All rights reserved. 9Public Improved Monitoring and Supportability Improved Diagnosis Information for Blocking Situations Runtime Environment Dump File Collection  To analyze issues e.g. if the system is unresponsive, RTE dump files can be created  On the Diagnosis Files tab, choose Diagnosis Information -> Collect…  You can specify: – From which index server(s) RTE dump files are to be collected – The number of RTE dump file sets to be collected – The interval (in minutes) at which RTE dump files are to be collected  For each specified index server, an RTE dump file containing information about threads, stack contexts, and so on is created and stored in the file indexserver_<SAPLOCALHOST>_<PORT>_runtimedump.trc.
  10. 10. © 2014 SAP AG. All rights reserved. 10Public Improved Monitoring and Supportability Enhanced Diagnosis Information Collection New Options to Collect Diagnosis Information  For the collection of all diagnosis information, it is now possible to enter a specific time period, by default the last 7 days.  Information from system views can be included when the database is online (this option is not available in diagnosis mode). Monitoring views for the planning engine are then included as well.
  11. 11. © 2014 SAP AG. All rights reserved. 11Public Improved Monitoring and Supportability Improved Resource Monitoring Redesigned Memory Allocation Statistics  Components shown in Memory Allocation Statistics now have more comprehensible names  Allocator section has been renamed to Subcomponents and now also includes row store information  Subcomponents are now grouped and displayed in a collapsible tree view
  12. 12. © 2014 SAP AG. All rights reserved. 12Public Improved Monitoring and Supportability Improved Resource Monitoring Statement Memory Tracking and Statement Memory Limitation: Avoid Uncontrolled Statement Memory Allocation  The peak memory consumption of a statement can be tracked und displayed in Expensive Statements.  Resource consumption collection has to be enabled manually: – Configuration file global.ini, parameters enable_tracking and memory_tracking  Additionally the HANA administrator is able to define a global statement memory limit in the database: – Configuration file global.ini, parameter statement_memory_limit  If a statement exceeds the memory limit, it will be cancelled
  13. 13. © 2014 SAP AG. All rights reserved. 13Public Improved Monitoring and Supportability Improved Resource Monitoring Enhanced Lock Classification  Locks are classified by component  Monitoring views M_SERVICE_THREADS and M_SERVICE_THREAD_SAMPLES contain this component in column LOCK_WAIT_COMPONENT to provide a hint on the purpose of the lock blocking the current thread.  Column Lock Wait Component can also be displayed on Performance tab -> Threads  Examples are: – Network IO – File IO – Basis System – Calculation Engine – Join Engine
  14. 14. © 2014 SAP AG. All rights reserved. 14Public Improved Monitoring and Supportability Improved Statement Analysis Extended Content of Plan Visualizer  For column store queries, the visualization of physical table access plan is now completed  This includes the display of inverted index access and predicate evaluation
  15. 15. © 2014 SAP AG. All rights reserved. 15Public Improved Monitoring and Supportability Improved Statement Analysis Operator List for Plan Visualizer  The Operator List lists detailed characteristics of all operators within a current plan (visualized + executed).  It can be used to dynamically explore the operator set along user defined filters in order to pinpoint specific operators of interest.  For example you might: – Filter all operators consuming a certain minimal CPU time – Then order those operators along the number of input rows – Further restrict the filter to a specific operator type (e.g. "Column Search”) – And then double-click on an operator of interest in order to check its positioning within a visualized plan
  16. 16. © 2014 SAP AG. All rights reserved. 16Public Improved Monitoring and Supportability Improved Statement Analysis Plan Cache: Keep Set of Parameters  The parameter set of a prepared statement is stored in monitoring view M_SQL_PLAN_CACHE_PARAMETERS to allow for the easy re-execution of a specific query: – First parameter set is stored when the total execution time of the statement is greater than parameter plan_cache_parameter_sum_threshold (default 1000ms). – Afterwards, the parameter values will be updated if the statement’s single execution time is greater than parameter plan_cache_parameter_threshold (default 100ms) and its last captured execution time.  Parameters to enable this feature: – plan_cache_parameter_enabled: Activate/deactivate capture of parameter values of prepared statements – plan_cache_parameter_for_lob_enabled: Activate/ deactivate capture of BLOB/CLOB/NCLOB parameter values.  In the Admin editor of SAP HANA Studio on tab Performance -> SQL Plan Cache the stored parameter set is used when you choose “Visualize Plan” or “Prepare in SQL Console”
  17. 17. © 2014 SAP AG. All rights reserved. 17Public Improved Monitoring and Supportability Improved Statement Analysis Direct Access to Plan Visualizer  It is now possible to display the visualized plan for a specific statement in the Expensive Statements Trace or SQL Plan Cache view
  18. 18. © 2014 SAP AG. All rights reserved. 18Public Improved Monitoring and Supportability Improved Statement Analysis Link Between SQL Plan Cache and Expensive Statements Trace  Navigation between the Expensive Statements Trace and the SQL Plan Cache view has been improved  You can display a specific statement in the other view using the context menu option Navigate To
  19. 19. © 2014 SAP AG. All rights reserved. 19Public Improved Monitoring and Supportability System Usage Type Display of System Usage Type  You can configure the usage type of an SAP HANA system (for example, production, development) during installation with the system_usage parameter or later by changing the system properties.  SAP HANA studio evaluates this parameter to warn users when they are about to perform critical operations on systems with usage type production (for example, execute SQL statements, stop or restart the system, perform a data backup, and so on)  This does not prevent data manipulation in productive systems, however it keeps reminding you to be careful
  20. 20. © 2014 SAP AG. All rights reserved. 20Public Improved Monitoring and Supportability Improved Usability User-Defined SQL Statements for System Monitoring  For customized monitoring, it is possible to save your own SQL statements on the System Information tab of the Administration editor for convenient repeated execution.  You can create and save individual statements directly on the System Information tab.  Alternatively, you can import multiple statements as text or ZIP archive files  To organize large numbers of statements meaningfully, you can define a folder structure. Predefined statements are stored in the System folder.  When you save the Administration editor, all statements, together with the defined folder structure, are saved to a single XML file and are available on the System Information tab of the Administration editor for all systems registered in the SAP HANA studio.
  21. 21. © 2014 SAP AG. All rights reserved. 21Public Improved Monitoring and Supportability Improved Usability Reworked Systems View Context Menu  The Systems View context menu has been re-structured by categories to provide a better overview and easy access to all actions for the user.  Old structure: New structure:
  22. 22. © 2014 SAP AG. All rights reserved. 22Public Improved Monitoring and Supportability Improved Usability Command Line Parameters for SAP HANA Studio  The SAP HANA studio program accepts command line parameters that allow you to specify the system to be connected to immediately on startup.  Call the SAP HANA studio executable with parameters for host, instance number and user: dbstudio.exe -h <host> -n <instance number> -u <username>  This can be useful to system administrators, as well as to other programs that call the SAP HANA studio, as this allows such programs to pass connection information to the studio.
  23. 23. © 2014 SAP AG. All rights reserved. 23Public Improved Monitoring and Supportability Statistics Service Improved Documentation  All statistics service views are now commented in the catalog, check the view definition to see the comments New Alerts  Expiration of database user passwords: checks if any password expires soon  Total memory usage of row store: determines the current memory size of the row store per host  Table growth of row store tables: determines the growth rate of row store tables  Row store fragmentation: check for fragmentation of row store  Inconsistencies in schemas: check for schema inconsistencies  Runtime of log backups currently running: determines if the most recent log backup terminates in the given time.  Enablement of automatic log backups: determines whether automatic log backup is enabled.  Storage snapshot is prepared: determines if the period, during which the database is prepared for a storage snapshot, exceeds a given threshold.  Total memory usage of table-based audit log: determines which percentage of the effective allocation limit is being consumed by the database table used for table-based audit logging.  Granting of SAP_INTERNAL_HANA_SUPPORT_ROLE: determines if the internal support role (SAP_INTERNAL_HANA_SUPPORT) is currently granted to any database users. The administrator should check if the corresponding users still need the role.
  24. 24. © 2014 SAP AG. All rights reserved. 24Public Improved Monitoring and Supportability Solution Manager Integration SLD Extension  A new (optional) software component can now be registered to SLD using the SAP HANA SLD Data Supplier: SAP HANA Smart Data Access.  The AFL package has been split into several packages. Therefore the AFL reporting for SLD has been adapted as well.
  25. 25. Additional Features
  26. 26. © 2014 SAP AG. All rights reserved. 26Public Improved Monitoring and Supportability Additional Features Support for Planning Engine  EPM models and EPM query sources are shown in the Systems view in the catalog tree.  If needed for support reasons, a planning engine trace can be activated. If parameter enable_export_wizard in section planningengine of file indexserver.ini is set to true, the Planning Engine Trace section is available on the Trace Configuration tab.  Monitoring views for planning engine are contained in the diagnosis information collection.
  27. 27. © 2014 SAP AG. All rights reserved. 27Public Improved Monitoring and Supportability Additional Features Import of Geospatial Information (shapefiles)  SAP HANA supports the ESRI shapefile format. ESRI shapefiles are used to store geometry data and attribute information for the spatial features in a data set.  You can import ESRI shapefiles into dedicated column- store tables using the import feature of SAP HANA studio: – From the main menu, choose File -> Import. – Select import source SAP HANA -> ESRI Shapefiles.  The shapefiles are imported into column-store tables in the specified schema.  Each shapefile corresponds to one table.
  28. 28. © 2014 SAP AG. All rights reserved. 28Public Improved Monitoring and Supportability Additional Features Extended system replication configuration  To offer higher levels of availability you can link together multiple systems in a multitier system replication landscape.  After setting up a basic system replication scenario you add a third system to provide another level of redundancy.  In a multitier setup the primary system is always on tier 1, a tier 2 secondary has a primary system as its replication source and a tier 3 secondary has the tier 2 secondary as its replication source.  The tier 3 secondary can now also be added using SAP HANA studio.  On each node only those actions are provided, which are currently possible – depending on the system status.
  29. 29. © 2014 SAP AG. All rights reserved. 29Public Improved Monitoring and Supportability Additional Features Enhancements regarding monitoring views  New monitoring view M_CS_LOADS shows when which column of a column store table has been loaded into memory  New monitoring view M_MVCC_OVERVIEW provides information about the row store multi-version concurrency control (MVCC) manager  New monitoring view M_TABLE_SNAPSHOTS provides information about tables which are blocked by table-wise garbage collection  Monitoring view M_TRANSACTIONS column ACQUIRED_LOCK_COUNT now also contains statistics for column store  System views can now be exported in CSV format
