Mark Thomas commented on DBCP-210:
----------------------------------

With Pool 2 this should be possible via a custom eviction policy that looks at 
how long the object has been alive.

> Have dbcp close pooled prepared statements after some settable time limit

> The problem is, when poolPreparedStatements is set to true and the database 
> is heavy loaded, the prepared statements are never closed. After some time, 
> as the database contents changes, they become unoptimal. It would be nice to 
> have another parameter telling for how long each statement can be kept open.
