Subject Re: [IB-Java] Connection pool
Author David Jencks
As far as I know noone is trying to add connection pooling functionality to
interclient: it certainly isn't there now.

I'm a little confused by the jdbc specs description of where connection
pooling functionality goes, and why they have a ConnectionPoolDataSource.
If you read the jca resource adapter spec, they are very clear that
connection pooling is functionality that an application server should
provide, and that an app server may provide different quality of service
for its connection pooling. The implementation of jdbc connection pooling
I have seen follows this model.

I have read that there are many others, however you may wish to look at the
jbosspool subproject of jboss ( for an implementation that
can be used to wrap interclient to produce pooling. I don't know exactly
how tied this is to the jboss infrastructure: I think it is independent.

The new driver (client-java in cvs) will have as its first supported mode a
jca resource adapter supporting xa transactions and pooling via an external
ConnectionManager. (The adapter is supposed to provide a default
ConnectionManager,.... we'll see when)
