You can also troubleshoot the outofmemory(OOM) or server

Answer / lakshmi

Trouble shooting starts with identifying the root cause.
Steps to follow:
1. check the logs
   usually trouble shooting starts with checking the logs.
2. enable debug
   (JAVA_OPTIONS=-verbose)
   through this we can identify which part of the code is      causing the problem.
3. take a thread dump
   kill -3 PID
4. take a heap dump
   jmap -heap:format=b PID
5. enable GC logs and analyze
   use GC viewer
these all are offline trouble shooting techniques. there is an imp technique, i.e.,
6. jconsole
   it connects to live jvm and makes an analysis through    profiling. it is a debugger and it makes a live          analysis.
if still problem raises,
7. service request
   here, oracle provides an oracle diagnostic agent called ODA. if still not solved, oracle tells you either to wait or upgrade.
