This needs to be a K.B.
The pool is set to mirror the active threads pool, if I recall. So the size
limit is the size of your endpoint.main.active pool, and the minimum is the same
as endpoint.main.min. The pool is dynamic, like the thread pool.
I would test performance to make my decision. But I have heard positive
feedback about our pooling mechanism, so I would recommend it. The only thing
better would be a JDBC driver version 2.0 with pooling built into the driver.
Multiple data sources in an app is not a problem. Did you look at the servlets
chapters of the Developing Applications guide? There are examples there of
connecting to data sources in JSP and servlets.

Subject: jrun3 connection pooling ..
I've been pouring over the docs regarding connection pooling in jrun3
and find it's not very detailed.
I see where you can choose when setting up a JDBC Datasource if you want
connection pooling, but I don't see anywhere where it tells more about
if there are specific properties relating to the pool that you can set
... i.e maximum number of connections, etc.
I need to get a detailed feel for the basic implementation ...to help me
judge whether I should keep using my existing pooling solution when I
switch to Jrun3 this week.
Am I missing something? Are there any more details to be had? I'm NOT
using EJB's ... so I'm not sure how much of the stuff on pg 263-264
(286-287 as the reader counts it) of the devapp.pdf where it shows
using ResourceManager.getConnection( ) etc.
If you're not using EJB and you wanted to use Jrun's connection pooling
... what would be the way you get a connection from the pool ? If you
had more than one JDBC datasource defined in the same jrun server, how
do you specify which one you want in a particular section of an app?
Thanks,
Lynn
