11.2.0.4 same query - slower response than 11.2.0.2 (using CBQT and optimizer_join_factorization)
Hi experts
We upgraded our eBS database from 11.2.0.2 to 11.2.0.4.
We have the same query , but now we get a worse execution plan with a higher cost. Obviously, the response time is worse when we use the OFE of 11.2.0.4
When we force OFE of 11.1.0.7 we get a good execution plan .
I will attach 2 files :
- Good execution plan :XAS_11107.TXT
- Bad execution plan : XAS
Please advise
