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.

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
