Oracle Solution for Error ora-00396

ORA-00396: error string required fallback to single-pass recovery

What triggered the Error:

The indicated error caused two-pass instance or crash recovery to fail. Recovery was retried with an alternate (slower) method to avoid the error.

What should we do to fix it:

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.
