2 likes994 views
The document provides practical tips for Oracle Business Intelligence Applications 11g implementations. It discusses scripting installations and configurations, LDAP integration challenges, implementing high availability, different methods for data extracts, and simplifying disaster recovery. Specific tips include scripting all processes, configuring the ODI agent JVM and connection pools for performance, understanding external LDAP authentication in ODI, implementing active-active high availability for ODI agents, choosing the right data extract method based on latency and volume, and using DataGuard and CNAMEs to simplify failover for disaster recovery.

- 6. [email protected] www.rittmanmead.com @rittmanmead What are we going to discuss today? • Practical Tips… - Installation and configuration - LDAP integration - High Availability - Disaster Recovery - Data Extracts 6
- 7. [email protected] www.rittmanmead.com @rittmanmead Why? • Oracle BI Applications 11.1.1.7+ - Still “new” on the market for BI Apps customers - Oracle Data Integrator (and GoldenGate) integration introduces new concepts - The 7.9.6.xx version will no longer be enhanced • We can all learn from past experiences 7
- 8. [email protected] www.rittmanmead.com @rittmanmead Oracle Business Intelligence Applications 11g • Complete, prebuilt BI solutions - Pre-packaged data models, ETL, reports and dashboards, built using OBIEE and Oracle Data Integrator 11g - Data sources include Oracle EBS, PeopleSoft, JD Edwards, Siebel, and SAP - Modules such as Human Resources Analytics, Financial Analytics, Project Analytics, and Student Information Analytics can be purchased • Conformed dimensions allow the use of data across modules 8

- 13. [email protected] www.rittmanmead.com @rittmanmead Installation and configuration • Run through the GUI once, then script…script…and script! 10 Tip: Script it!
- 14. [email protected] www.rittmanmead.com @rittmanmead Why script? • Create a repeatable process - Simplifies subsequent environment builds - Sandbox, Development, Test, Production, etc will follow the same build process - Build upon previous scripts as patches are installed or new requirements are discovered • Documentation writes itself… well, sort of 11
- 15. [email protected] www.rittmanmead.com @rittmanmead Why run the GUI installer first? • Work through the parameters, order of steps, etc • Generate a response file or build a script 12
- 16. [email protected] www.rittmanmead.com @rittmanmead Response file • Pre-filled parameters in a text (.rsp) file • Standard approach to “silent” installations • Can be created for most install or configuration processes 13
- 17. [email protected] www.rittmanmead.com @rittmanmead Configuration 14 Tip: Boost performance
- 18. [email protected] www.rittmanmead.com @rittmanmead Configure the ODI Agent JVM 15
- 19. [email protected] www.rittmanmead.com @rittmanmead Increase Connection Pools & Database Processes • Each session in ODI is a new connection to the repository and data warehouse - Ensure the concurrent database processes are set to allow plenty of connections - Up the connection pool max capacity 16
- 20. [email protected] www.rittmanmead.com @rittmanmead ODI Agent Sessions • Default is 10! That’s not gonna fly… • Update in ODI Studio or Console and set to a value that will meet performance needs 17
- 21. [email protected] www.rittmanmead.com @rittmanmead LDAP configuration • WebLogic Server embedded LDAP - setup out of the box • External LDAP can then be integrated during configuration 18 Tip: External LDAP gotchas
- 22. [email protected] www.rittmanmead.com @rittmanmead LDAP configuration • OBIEE - Uses Oracle Virtual Directory - Embedded LDAP users (“biadmin”) and external LDAP users can both access the same resources • ODI - Only one “type” of external authentication can be used at a time - Creates challenges when using the embedded LDAP users 19
- 23. [email protected] www.rittmanmead.com @rittmanmead LDAP configuration • Amazingly, the ODI Agent can still connect using either an embedded LDAP or external LDAP user 20
- 24. [email protected] www.rittmanmead.com @rittmanmead External Authentication with Oracle Data Integrator 21
- 25. [email protected] www.rittmanmead.com @rittmanmead If ODI Supervisor user is… • …an embedded LDAP account (as is default), you must add external user via the ODI repository DB 22
- 26. [email protected] www.rittmanmead.com @rittmanmead If ODI Supervisor user is… • …an embedded LDAP account (as is default), you must add external user via the ODI repository DB 22
- 27. [email protected] www.rittmanmead.com @rittmanmead If ODI Supervisor user is… • …an external LDAP account, you must change credential mapping in WebLogic 23
- 28. [email protected] www.rittmanmead.com @rittmanmead High Availability 24 Tip: Do it
- 29. [email protected] www.rittmanmead.com @rittmanmead High Availability - ODI Agents • Active-active High Availability - Load balancer handles HTTP web request to the agent • One node acts as scheduler - Coherence handles schedule failover - New sessions begin on new node, but previous in-process iterations will not continue 25
- 30. [email protected] www.rittmanmead.com @rittmanmead Data Extract Three ways to extract source data • JDBC mode • Database link mode • SDS mode 26 Tip: Choose wisely
- 31. [email protected] www.rittmanmead.com @rittmanmead Data Extract • JDBC mode - Default method for data extraction - Streams records through the ODI agent for datatype conversion - Useful for heterogeneous source/target • Database link mode - Use the database link native functionality in Oracle database • SDS mode - GoldenGate data replication extracts transactions and loads into target Source Dependent Data Store (SDS) schema - Useful if network latency is high or volume of transactions high 27
- 32. [email protected] www.rittmanmead.com @rittmanmead GoldenGate - Data Replication - SDS Mode • Oracle GoldenGate - High-performance data replication - Minimal impact on source and target systems • Why use GoldenGate? - High transaction rate - Network latency an issue - Need ability to delete from target 28

- 39. [email protected] www.rittmanmead.com @rittmanmead Disaster Recovery Failover and Switchover Simplified • Update Global CNAMEs • Switch primary database via DataGuard • Update the Web Catalog and Application Role assignments • Start NodeManager, OHS, WebLogic AdminServer • Update Embedded LDAP User GUID in ODI (if necessary) • Start BI and ODI Managed Servers • Update and Deploy the RPD • Start the BI Services 33
- 40. [email protected] www.rittmanmead.com @rittmanmead Reviewing the Tips • Practical Tips… - Installation and configuration ‣ Script everything! ‣ Increase sessions and JVM settings for performance improvements - LDAP integration ‣ Watch out for those “gotchas” around the ODI agent user - High Availability ‣ Just do it…but also, understand how it works - Data Extracts ‣ Pick your type based on source-to-target latency and volume of transactions - Disaster Recovery ‣ Simplify with DataGuard and CNAMEs 34
