What to do when shutdown immediate appears to hang:
Sometimes, the message 'Waiting for smon to disable tx recovery' is posted in the alert log.
This note only addresses situations when the apparent hang occurs when the database is going from OPEN to DISMOUNT, which is actually the most common situation.
If the apparent hang occurs at a different step, then this note does not apply.
