Subject Cloese database connection
Date Wed, 08 Jul 2009 13:12:01 GMT

I am using OpenJPA with managed transactions and connections on an IBM WebSphere Application

Extract from persistence.xml:
<property name="openjpa.TransactionMode" value="managed"/>
<property name="openjpa.ConnectionFactoryMode" value="managed"/>

Configuration WAS:
JDBC - datasources - non XA connection

When does a managed connection open and when does it close?
My problem is that many connections will be opened that are never closed again. Even if I
shut down the Server, the connections remain open.

Thank you for help
