all, recently i have concurrent session (active+nonactive) around 8000 users, and shared server. but sometimes i have stuck with some session, so that manual kill i have to be done. my thinking is how to use oracle connection manager (CMAN) and dedicated server so that it will reduce the session + processes in the database server, but need information for anyone who use CMAN, the pros and cons...... thanks for the sharing... -- regards ujang -- //www.freelists.org/webpage/oracle-l
