Performance Tuning Techniques in OBIEE 11g

Steps to improve the performance.

1. implement caching mechanism
2. use aggregates
3. use aggregate navigation
4. limit the number of initialisation blocks
5. turn off logging
6. carry out calculations in database
7. use materialized views if possible
8. use database hints
9. alter the NQSONFIG.ini parameters

Note:calculate all the aggregates in the Repository it self and Create a Fast Refresh for MV(Materialized views).
and you can also do one thing you can schedule an IBOT to run the report every 1 hour or some thing so that the report data will be cached and when the user runs the report the BI Server extracts the data from Cache
