Dear team,

In QA DB server , Today I got ORA-00020

Check and found too many active sessions from v$session.

The question is that the username column is blank.

Program - JDBC Thin Client

OSUSER - pqadmn

Since our sys and system users are in locked state.

Hence I am unable to find the real culprit.

Audit trail is not showing any login information and only filled with ora-01017

Attaching some logs

1) You should post the contents of your text file in line in [code] tags. Lots of people won't/can't download attachments.
2) What exact queries did you run to get that output?
3) Given that you've got a 120 sessions with program JDBC Thin Client, osuser pqaadm and no username the obiovus thing to do is look on the server to see what pqaadm is actually running. There's a good chance it's just the one program.
In fact, given all the other sessions are either toad, sqlplus, sql Developer or oracle internal, isn't the JDBC thin client your application front end?

I suspect the root cause is a rogue application code in the middle tier.
Post excerpt from listener.log showing the login requests which consumed all the sessions allowed.
ORA-01017 indicates failed login attempts due to incorrect USERNAME/PASSWORD combination

SYS is never locked even of its state is LOCKED.

I concur with this hypothesis.

All those active sessions with no username hanging on library cache locks looks to me as though your middle tier is trying to establish a connection pool a bit too quickly. If you really are killing the processes, it will probably keep retrying and make the problem worse until you hit your PROCESSES limit and get the ora-20 errors.

We don't need to thousands of records and only need to a couple of dozen of representative records/rows which can be COPY & PASTED into new entry here

A session is created before being authenticated. How else could the session determine that the password is wrong?

It is pretty obvious that your middle tier is bombarding the database with connection requests that have the wrong password.
You need to fix that before anything else.

But as per wait event , It is showing library cache lock, that's show session is created and query is in parsing process in shared pool.

Well, yes. It takes quite a few queries to authenticate a user.

Have you looked at the middle tier yet? That is likely where the problem is. As you have been told. Repeatedly.
