Please let me know your views on the same. If you are in dedicated server environment then for the first step do the following: alter system set resource_limit=true; create profile only30minutes_of_inactivity limit idle_time 30; alter user <username> profile only30minutes_of_inactivity; For the next step, read Note:96170.1 on metalink which provides you the shell script for killing sniped (sessions with exeeded idle_time limit) sessions. You have to run this script by cron. Egor http://www.oracledba.ru/orasrp/ Free Oracle Session Resource Profiler -- //www.freelists.org/webpage/oracle-l
