Hello @Sasanka ,

We can identify with the server logs at below location.
New logs gets created everytime you restart.
IFS_Home/wls_domain/servers

Within server you can choose folders as
AdminServer/logs

MainServer1/logs

IntServer1/logs etc…

Hope this helps!

Hello @Sasanka 

You can look for below blocks under weblogic server logs:-

1> JAVA Memory arguments:
2> CLASSPATH=

3>***************************************************
*  To start WebLogic Server, use a username and   *
*  password assigned to an admin-level user.  For *
*  server administration, use the WebLogic Server *
*  console at http:\\hostname:port\console        *
***************************************************

4>JPS bootstrap service started

Good luck!

Hardik
