I have a basic question related connection pooling. How does connection pool handle the session variables? Say there are 2 connections in the pool Say an application grabbed a connection from the pool say SID of the session is 100 It updated Table emp and prompted user A for save/cancel to commit/rollback. At this point in time user A either closed his browser or switched the PC off. After few moments another user B launched another browser and launched the application grabbed the same session SID 100 ( Assuming that earlier connection was returned to the pool ) made some changes and committed it. Now whether the changes made by A are also committed?? If user A's application had set certain packaged variables then what happens to them? Whether they are all retained or reset? If they are all cleaned up, who does it? app server or JDBC driver? Thanks Deen -- http://www.freelists.org/webpage/oracle-l
