There is no problem Oracle is just "waiting for active calls to complete".

Something is still "alive" in the database and keeping it busy.
Seems your tool trying to do a clean shutdown.
Try again when there is no activity. It is not a problem. Just expected behavior.

If you made a "normal" shutdown, Oracle waits everyone disconnects.
If you made an "immediate" shutdown, Oracle waits all transactions end (possibly currently rolling them back).

Hi,

Check
1/ v$session, only sessions with status='ACTIVE' if shutdown immediate
2/ v$transaction, all of them

Hello Mr Michel,

Padhu already executed "shutdown" command; I think now there is no way to connect database (using sys also).

Only option need to wait or asking to close all session or need to fire abort command.

Please correct me.

You're right if he wants to follow the shutting down, he has to open 2 SYS sessions, one to execute shutdown and the other one to follow the process (if shutdown normal, in case of shutdown immediate the second session will be killed soon).

Hi All,

Is there any other way to find session or process or transaction performed at that time of scheduled backup, which didnt allow shutdown of database.

your reply would be helpful in preparing the Root cause analysis.

padhu

You may rephrase the same question any number of times you want.
Did you read any of previous responses?
Root cause is your application is trying to shutdown it down cleanly.
Any active user / process will hold the shutdown until the job is done.
Instead of worrying what to do after the shutdown was issued, You have to check for active sessions before you shutdown.
The methods are hinted by Michel.

thanks.

Ok, i had read the previous responses. last question which i asked is to find the exact session or process. It is an unattended backup, scheduled by another DBA(Diff vendor).

Finally Here i just asked to prepare the Root cause analysis alone.

I am happy to receive the quick responses from you all.thanks a lot.

regards,
padhu
