Hello All,
Just curious to know if the below issue can be resolved or does it has any oracle bug which rectifies the below situation.


1.Database details --  Oracle RAC 11.2.0.3 ( two node on AIX)

11.2.0.3.2  PSU applied for July ( Upgraded from 11.2.0.1 to 11.2.0.3 and applied the PSU)

Issue -- SQL_ID & HASH PLAN changes for every execution which increases the response time and violates the SLA time for a single query which we came across still now.

Please let me know if anyone of you have faced a similar situation and got a solution for this issue. Thanks in advance!!


Thanks
Bhaskar
