ODI PERFORMANCE

ODI is a metadata driven (SQL) code generator using code templates (knowledge modules). It uses a Java

agent to communicate and send data between source and target systems and the repository over

the network.


SQL

- > 80%: ODI performance issues = SQL issues => SQL main ODI skill

- Perfect your SQL. Advanced SQL. Analytic Functions

- Know your database(s) inside out. In particular the target

- Understand, write, and modify Knowledge Modules


AGENT

- Light weight Java based application- Tied to host OS- Generates code based on ODI metadata.- Communicates source, target, repository.- JDBC data transport- XML- Jetty- Interpreters: Jython, JBS, JavaScript, Groovy- HSQLDB in memory database- Scheduler- Sizing


AGENT

Target- Least amount of roundtrips. Network (JDBC, XML)- One target database server only (DW)Another Server- ODBC drivers- JEE agent on Weblogic- No support for target OS- Resources on target- DBA


INTERFACES

- No!! KM using row by row processing- Use ODI functions rather than DB functions- Don’t overuse CKM (especially for large data

volumes)- temp indexes (I$)- Gather statistics (C$, I$, TGT when applicable)- Rule of thumb: Use loader KMs or db link

KMs rather than JDBC KMs


SOURCE/TARGET

- Schemas on same database server. Physical schema and not data server.

- Have sources physically close to target- Minimize impact on source- Chunking

DEPENDENCY DRIVEN SCHEDULING

• Simplifies orchestrating the flow– only immediate upstream definition required– execution timings not relevant– self-adapts in the most effective way

• Improves overall E-LT performance– Less idle resources – better utilization– Independency– unveils its full potential in complex Enterprise class

DWHs (Inmon)


DEPENDENCY DRIVEN SCHEDULING

• Notifications– errors (+auto-restartability)– finish summary– logging

• Multiple/overlapping E-LT streams– load with different frequencies

• Parameterization– improved system stress control– process prioritization
