Hi Andy,

JIRA JDO-53 suggests to use JPOX connection pooling to improve TCK 
performance.

I followed the instructions decribed in 
"http://www.jpox.org/docs/1_1/rdbms_connection_pooling.html" and ran 
JPOX 1.1.0-beta-3 with commons-dbcp. To me, it looks like there is no 
performance improvement executing the TCK.

So maybe, I made a mistake and you can help. This is what I have done:

1) Downloaded JPOX plugin for commons-dbcp (jpox-dbcp-1.1.0-beta-3.jar)
2) Downloaded commons-dbcp (commons-dbcp-1.2.1.jar)
3) Downloaded commons-pool (commons-pool-1.2.jar)
4) Downloaded commons-collections (commons-collections-3.1.jar)
5) Added a JPOX property to PMF properties 
(org.jpox.connectionPoolingType=DBCP)
6) Added all jars to the classpath and started the TCK

Is there anything missing?

Please note that each TCK test has the following pattern:

pmf = JDOHelper.getPersistenceManagerFactory(..);
...
pmf.close();

Does PMF.close invalidate or clear the connection pool?

Regards,
Michael
