RE: shutdown abort / startup restrict / shutdown vs. shutdown imm

The differences are
1. shutdown abort - is more drastic, no new users are allowed to log in, disconnects current sessions without rollback, recovery however would have to be done when restarted.
2. shutdown immediate - no new users are allowed to log in, terminating current connections, transactions terminated are rollbacked, recovery would not happen at restart
3. shutdown normal - no new users are allowed to log in, transactions in progress are rollbacked, but would wait for all existing transactions to finish and users to log off, so if a user is logged in when shutdown normal is executed, it would wait forever.  

So shutdown immediate is much quicker and safer. ...Ishrat

This might be a naive question, but why is -> shutdown immediate
better than
-> shutdown abort / startup restrict / shutdown normal ?

(That is assuming of course that no user / job will try to sneak in after you do the startup restrict)
