Try "shutdown abort", takes about 2 seconds...works for me (ROFLOL)

If you are doing a "shutdown" or "shutdown normal" (same things) then Oracle waits for all sessions to disconnect, flushes everything, and checkpoints the database, could be a long wait.

If you are doing a "shutdown immediate" then all sessions will be terminated, uncommitted transactions rolled back, the buffer cache needs to be flushed, and the database will be checkpointed. Can take awhile if your checkpoints are spaced far apart.

If you do a "shutdown abort" be aware that cache recovery must be done on instance startup so startup may take a few minutes, again depending how long your checkpoints are spaced.

(Trying to remember all of the above from memory, and I'm getting old. So
if any of it is incorrect, remember, the consulting fee cost $0.00)

                    to ORACLE-L

Does any know why it takes too long (about 40 minutes) to shutdown oracle database? I am running oracle8.0.5 on solari5.6. It usually just takes me few minutes to shutdown.

Thanks,
David
