ORA-01618: redo thread string is not enabled - cannot mount
Cause: The INIT.ORA parameter "thread" requests a thread that is not enabled. A
thread must be enabled before it can be mounted.
Action: Shutdown the instance, change the INIT.ORA parameter and startup
mounting a different thread. If the database is open in another instance then the
thread may be enabled.
