Subject [jira] [Commented] (POOL-99) Test for idle time exceeded in borrowObject
Date Mon, 15 Aug 2011 16:37:27 GMT


Mark Thomas commented on POOL-99:

In that scenario, simply execute a validation query (which is good practise anyway for DB
connections which can fail for all sorts of reasons).

> For GenericObjectPool, the evictor thread performs a calculation to determine if an idle
object as "expired." If it has, the object is destroyed.
> Would like borrowObject to perform the same test and destroy behavior.
> I explored using the testOnBorrow facility but the time that the object went idle is
not available. Only the pool has access to the ObjectTimestampPair object that is used to
record the time that the object was placed in the pool. I explored placing a timestamp in
the pooled object and can do that but it would seem better if the pool managed that test itself.
