OCI-38857

cannot mark redo thread string as enabled

Cause

The standby switchover or failover operation failed because it needs to mark a redo thread as enabled. However, the control file was recreated with a MAXINSTANCES value smaller than the thread number of the redo thread.


Action

Recreate the control file with a larger MAXINSTANCES value.
