ORA-01216: thread [string] is expected to be disabled after CREATE CONTROLFILE
Cause: A thread that was given during CREATE CONTROLFILE is enabled, but the datafiles indicate that it should be disabled. This is probably because the logs supplied to the CREATE CONTROLFILE are old (from before the disabling of the thread).
Action: This thread is not required to run the database. The CREATE CONTROLFILE statement can be reissued without the problem thread, and, if desired, the thread can be recreated after the database is open.
