Thread: Connection Pooling?

Connection Pooling?

From
Adam Haberlach
Date:
    This may be a Postgres JDBC question, but it may also be an
Apache Jakarta/Tomcat question...

    I recently moved a few of my pages over from PHP to .jsp and
now I notice that I've got postgres backends sitting around, as
though some of my connections are being pooled or persistant.
As far as I can tell, my scripts are correctly closing the
connections, so they shouldn't be sitting around--does anyone
know if there is some automatic pooling/persistant connecting
happening, either in the JDBC driver or in Tomcat?  How would I
turn this off or adjust it down?

Adam,

No there isn't automatic pooling in jdbc. I would look over your jsp
again.
