Logs to review after PROD outage

in Technology Stack - EBS (MOSC) 1 commentAnswered

Yesterday afternoon we had an issue with the Production environment. A user might be able to login to the login page but the forms would not launch. I logged into the Web Logic Console and clicked on Server. It just spun and would not open the server page. So, I used $ADMIN_SCRIPTS_HOME/adstpall.sh to shutdown the apps and the shutdown process hung. I had to kill off all the remaining processes. Everything restarted without a problem.

What logs would be the best to review to try to analyze the problem?

We have 4 oacore_servers. I looked in the diagnotics logs for each and oacore_server1 had an java.lang.OutOfMemoryError around the time the problem started. How do I find more information about the cause of the OutOfmemoryError? Would one oacore_server1 having a memory error have caused the whole environment to stop functioning?
