Re: Pool project still active

[Chad La Joie]

You're probably see the result of this bug.  If you set the pool to a -1 
that does not mean no connection limits (as the Javadocs say).  It seems 
to interrupt that as meaning max allowable connections of -1.  So if you 
don't have your pool exhausted behavior set to make the pool grow when 
it's out of connection the pool will always fail to get a connection 
(since it has -1 of them available).

Even if you do set the pool to grow when exhausted, which does get 
around the -1 problem, if you set your idle connection reclamation 
settings low you'll still basically be without a pool as the pool will 
likely always be creating new connections when you request one.

So my suggestion, if you want an unlimited number of connections is to 
set the max allowable connections to Integer.MAX_VALUE, which is really 
the max possible connections you can have open anyways.

Could you tell what this bug was? We are having an issue with the Torque 
connection pooling where if we set defaultMaxActive to anything other 
than -1 we see poor performance in our load tests. If you know what this 
bug was plese let me know.
Thanks

Is the Pool project still active?  I noticed a bug dealing with the 
max active connection behavior that was patched about a year ago, but 
no release was made incoporating that change.  Is there any activity 
in that group, and if so could you please releae a 1.0.2 release that 
contains this and other bug fixes, or comment on whether the nightly 
builds are production quality.  Thanks.
