Gordon,

Just for grins and giggles try adding this as a test:

    <parameter>
     <name>removeAbandoned</name>
     <value>true</value>
     </parameter>

     <parameter>
     <name>removeAbandonedTimeout</name>
     <value>60</value>
     </parameter>

To reclaim abandoned connections.

If it drops you back to the min then you have a leak in you app.

Check that connections, resultsets and statements are all closed.

Here my setting...

My problem is ... Connection pool look like don't open 10 connection at
start-up, and when my servlet run for a while... Let it open up more
connections(over 30) and then wait... (after a night .. :-D)... When I
check database server, it still open more connections, I expect min. for
10 only.

My setup anything got wrong?  Thx.

Hi All,

   May be I missing understand the DBCP configuration. Anyone could
help ? I want my connection pool are Max 100 connection, 10 conn. At
start-up, max idle 10, when idle for 10 min then kill it. Something like
that.

Thanks.


Regards,


Gordon Luk
