[jira] Created: (ODE-395) MessageExchangeDAOs of in-memory
processes are kept in memory despite release()
MessageExchangeDAOs of in-memory processes are kept in memory despite release()
-------------------------------------------------------------------------------
Key: ODE-395
URL: https://issues.apache.org/jira/browse/ODE-395
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Affects Versions: 1.3
Reporter: Jürgen Schumacher
We have experienced a high memory consumption by ODE in scenarios where in-memory processes are invoked with a relatively high frequency. This is caused by the org.apache.ode.bpel.memdao.BpelDAOConnectionImpl which keeps the created instances of MessageExchangeDAOImpl in memory until they exceed the TIME_TO_LIVE (hardcoded constant). This way we have around 400 of these unneeded (at least for us ;-) objects hanging in memory occupying around 30 MB of memory all the time.
I've created a patch that removes the MessageExchangeDAO objects from the in-memory BpelDAOConnection as soon as the invoker of the process calls release() on its MyRoleMessageExchange object. It's probably too simplistic, but in my test cases it works without a problem.

[jira] Updated: (ODE-395) MessageExchangeDAOs of in-memory
processes are kept in memory despite release()
Posted by "Jürgen Schumacher (JIRA)" <ji...@apache.org>.

Jürgen Schumacher updated ODE-395:
----------------------------------
Attachment: inmemory-mexdao-release.patch
Extends BpelDAOConnection with a releaseMessageExchange(String mexId) method that is called by MessageExchangeImpl via ODEProcess in the release method. This releaseMessageExchange method is implemented only in the memdao implementation of the interface, the jpa and hibernate methods do nothing.
