Registering Application Connection usage

Question

Hi All,
I'm using Oracle 10 ojdbc library for creating cached connections, using OracleDataDource and OracleConnectionCacheManager class to handle pooling of connections. Our DB admin is currently having a hard time monitoring connections since there were alot of applications/instances connecting to the DB. So it was proposed that on creation of a connection it will call a callable statement registering itself (the connection) and the application using it.
My problem is, since the connection is created and pooled by the OracleDataSource how can I tell the OracleDataSource to do this upon creation of a connection. I checked the ConnectionListener and it only handles closeEvents. Or is there a better way of tracking/registering application per connection usage.
(BTW is was also propose that we assign seperate usernames for each applications but since the oracle license limited the number of users per DB it was later scraped since there were alot of applications and replicated instance running.)
Thanks.

(BTW is was also propose that we assign seperate
usernames for each applications but since the oracle
license limited the number of users per DB it was
later scraped since there were alot of applications
and replicated instance running.)I can't know what license you have, but named user licensing doesn't restrict how many accounts you can create. It restricts how many real people can benefit from the database. For example, a user group of 1000 people that uses an application that uses only a single name for logging in and accessing the database still needs to be licensed for 1000 users. On the other hand, a small group of 20 employees could have apps that actually require 200 user accounts -- and they would only need to be licensed for 20 users. There are minimum user requirements per cpu and such, and there have been many licensing models. I don't know what your license says, but what I described, I believe to be the most current for 'named user'.
