Ebs r12 oacore memory

Question

Hi All,
Ebs r12.1.3
rdbms 11.2.0.2
I would like to know if there is a way to monitor oacore memory usage and if there is a way to alert us when the memory is close to the maximum memory available (-Xmx parameter)?
I also would like to know, our oacore seems to fill during the week and at one point, doesn't have enough memory and they froze/crash. We have to bounce them to fix the issue.
Does any of you do on a regular basic a bounce of OC4J components (adopmnctl.sh stop / start) ?
Thank you,
Felix

Hi,
Oh, I forgot I already asked the same question :S
I am trying to use jconsole but in the local tab, I do not have any oacore process, only GSM.
I am getting the PID from $INST_TOP/admin/scripts/adopmnctl.sh status.
When I try to do jconsole PID, I am getting:
[server.domain.com]:> $INST_TOP/admin/scripts/adopmnctl.sh status
You are running adopmnctl.sh version 120.6.12010000.5

If I simply start jconsole without providing PID, I can see the local JVM. All I see is the FNDOPP / FNDCPGSC processes, nothing else.
Any idea?
Thank you,
