Tip of the Week- JVM process show high CPU..... kill -3
If you are encountering performance/hang issues with your EBS instance and notice the JVM processes are showing high CPU, then suggest you perform kill -3 on the JVM process.
KILL -3 for JVM Process (thread dump)
----------------------------------------
To take a thread dump on Unix/Linux, you need to issue the following:
kill -3 jvmpid
where jvmpid is the jvm process id on the OS.
The output will go to :
> EBS 11i : $iAS/Apache/Jserv/logs/jvm/OACoreGroup.*.stdout file.
> EBS R12: $LOG_HOME/ora/10.1.3/opmn/logs/opmn/oacore_default_group_1/oacorestd.out
Run the command for all JVMs during the hang.
