ORA-00396: error [string] required fallback to single-pass recovery
Cause: The indicated error caused two-pass instance or crash recovery to fail. Recovery was retried with an alternate (slower) method to avoid the error.
Action: Correct the cause of the indicated error (also recorded) so that future instance or crash recovery can succeed with the two-pass algorithm. This usually requires making more main memory available to the recovery process.
Error Type: ORA
