Oracle Error ORA-32012: SPFILE format is inconsistent with value of COMPATIBLE parameter

Oracle Error Message

ORA-32012: SPFILE format is inconsistent with value of COMPATIBLE parameter

Reason for the Error

The SPFILE was in H.A.R.D. (Hardware Assisted Resilient Data) compliant format but the value of the COMPATIBLE parameter was set to pre-11.0. This is not allowed since Oracle has a policy of irreversible compatibility advance.

Solution

Change the value of the COMPATIBLE parameter to be 11.0 or higher.
