Hi, Usually, to do a stress test is not do anything like a crazy it must follow a goal, so it must be restricted to some rules always. I think the stress you want is a stress test, using the usual work you do daily, to be sure after you migrate, things works ok. So you must do a plan for it. The other stress, valid too, is to do any kind of queries, but this implies optimizing. And do you really need to optimize to reports to run a year, when that hardly happens? I would do two test, 1. a test to see everything works ok, doing the daily work. So a group of user do the daily work. 2. a test to see if unusual work, works ok too. But I would do it in differents times so you see test 1 is not slow neither hang the database, and in 2 you expect this can be slow, but it must not be too much. -- //www.freelists.org/webpage/oracle-l
