Re: dbshut script - shutdown or shutdown immediate

Well said. This topic has been circulating in many DBA forums for a long time. Shutdown immediate does rollback and will take time if no.of users is high. On the otherside, shutdown abort simply takes the db down and does not bother about anything else. As per manual, if you do a shutdown abort then you WILL need the online redo logs for recovery just in case. Think twice if your db is in NOARCHIVELOG mode. If your db is in ARCHIVE mode make sure the logs are multiplexed. Though Oracle's recovery seems to be sturdy, double check your backup & recovery strategies. Also, which option to use is influenced by how much downtime/shutdown time you can afford.
