Oracle Access Manager - Version and later
Information in this document applies to any platform.


We had OAM 11gR2PS1 ( and then upgraded to OAM11gR2PS2 BP01 ( While performing the PS2 schema upgrade, we experienced the below error and we had resolved it by reducing the CPU count on the database from 80 to 2. After completing the PS2 upgrade, we reverted the CPU count back to 80.

Now, while creating Application Domains on oamconsole, we are experiencing the following error - ' The policy store is not available; please see the log file for more details.' As per this, we checked the logs and found the same error (mentioned below) that we observed while performing the PS2 schema upgrade. After changing the CPU count value on the database from 80 to 2, we could successfully create application domains without seeing this error. Anyhow, CUstomer need to keep CPU count to 80.
