I am using Oracle 9i. I am using the Oracle's Connection Pooling (OracleConnectionCacheImpl). I am having a strange problem. I have set all the properties and run the application. Sometime I receive a null connection object instead of an Exception. Ideally it should through an exception if it is unable to find the connection in the pool. I have set the Cache Scheme as Dynamics.

I am here unable to decide whether its the problem with the API's or its something to do with the Oracle Server setting.

Thanks for your help.
