Try this: From a command prompt - type
ps -ef&#124grep oracle (show all processes running under the oracle username)

Look for ora_pmon_instance-name for each database - if you show no "pmon" (process monitor) processes running, then your DB's might be down

Hope that helps !

Thanx Daniel,
You are right .
But my question was that i want to check all of my database is OPEN or not,becasue i have 10 database and there is automated script which run at evrey friday for backup, which shut down all the database and take full offline backup of all databases and then open all the database.
But for the last one month it happen 2-3 times that some of my database started up to MOUNT stage but does not get OPEN.
So is there any way to know which database is not OPEN so than means hangs up to nomount or mount stage .

Thanx and Regards
