Hi,

We have a oracle 10g database accessed by many application.

because of error

ORA-00054: resource busy and acquire with NOWAIT specified

no one is able to login to the application.

while checking the lock history, it has more lock in all the table. we manually killed some of the session who locked on these tables.

But still as new session starts again its not going to be a solution.

What are the other ways that we can fix the solution for this error?

DB: ORACLE 10G
OS: Sunsolaris

Pls advice

Thanks and Regards,
Prashanth

SELECT DECODE(request,0,'Holder: ','Waiter: ')||sid sess, 
id1, id2, lmode, request, type
FROM V$LOCK
WHERE (id1, id2, type) IN
(SELECT id1, id2, type FROM V$LOCK WHERE request>0)
ORDER BY id1, request
/


Does the SQL above return any rows?

You now know which session are the cause of the bottleneck (the holders) & know which objects are being contended for.

You need to decide what is best course of action to eliminate the logjam & execute appropriately.

Hello prashanthgs,

This is NOT backup related question. You should be read

http://www.orafaq.com/forum/t/88153/0/

ORA-00054: resource busy and acquire with NOWAIT specified


As per Mr.Anacedent, Object busy with some other session. You can re-try your operation later or you can kill blocked session.
