Subject [jira] Commented: (DBCP-212) PoolingDataSource closes physical connections
Date Sun, 22 Feb 2009 19:41:01 GMT

    [ https://issues.apache.org/jira/browse/DBCP-212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675697#action_12675697

Mark Thomas commented on DBCP-212:
----------------------------------

I can't see a good reason for the sync on makeObject() so I removed it. It does seem to do
a little to alleviate the problem but the issue is still significant.

> By executing the attached program and monitoring the process id of the physical connections
at the database server, it is possible to demonstrate that the connections are being actually
physically closed and reopened by the application at a very high rate.
