What are we going to discuss today?

• Practical Tips…- Installation and configuration- LDAP integration- High Availability- Disaster Recovery- Data Extracts

6


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


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

Installation and configuration

• Run through the GUI once, then script…script…and script!

10

Tip: Script it!


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


Why run the GUI installer first?

• Work through the parameters, order of steps, etc

• Generate a response file or build a script

12


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


Configuration

14

Tip: Boost performance


Configure the ODI Agent JVM

15


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


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


LDAP configuration

• WebLogic Server embedded LDAP - setup out of the box

• External LDAP can then be integrated during configuration

18

Tip: External LDAP gotchas


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


LDAP configuration

• Amazingly, the ODI Agent can still connect using either an embedded LDAP or external LDAP user

20


External Authentication with Oracle Data Integrator

21


If ODI Supervisor user is…

• …an embedded LDAP account (as is default), you must add external user via the ODI repository DB

22


If ODI Supervisor user is…

• …an external LDAP account, you must change credential mapping in WebLogic

23


High Availability

24

Tip: Do it


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


Data Extract

Three ways to extract source data

• JDBC mode• Database link mode• SDS mode

26

Tip: Choose wisely


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


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

Disaster Recovery

If the reporting and analytics generated by BI Apps is critical to your business, make sure it’s available!

31

Tip: DR can be simple


Disaster Recovery Architecture

32


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


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
