Subject [jira] Commented: (DBCP-343) RemoveAbandoned setting closes the active connection.
Date Mon, 13 Sep 2010 11:33:33 GMT

    [ https://issues.apache.org/jira/browse/DBCP-343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12908727#action_12908727
] 

Phil Steitz commented on DBCP-343:
----------------------------------

Patches welcome on javadoc.  To be clear, it is not strictly speaking the age of the Delegating
statement that counts, it when it was last used.  My comment above may have been misleading.
 Have a look at DelegatingStatement,executeQuery() for example.  If you can confirm actual
JDBC operations that do not update lastUsed, then we should view this as a bug.

> The documentation says, RemoveAbandoned connection setting will remove only the connections
that are idle for the configured timeout. But I see it is closing the connections that are
active.
> The logic in DBCP implementatoin shows that it calculate the idle time from the time
of the connection is created, irrespective of the connection is used. So it just close the
connection in removeAbandonedTimeout.
> In my code, I'm reusing the connection for more DB statements to do intensive db operations,
which hold the connection for more than 5 minutes . The connection will never be idle for
more than a few seconds.
> My setting of removeabandonedTimeout = 300 brutally closes the connection in 5 minutes,
without checking if the connection is in use or not.
> I assume it should involve the activity of the statement object also to do the idle time
calculation.
> thanks,
