I had about three days to review something like 15 peoplesoft databases plus looking into a few specific slow-running queries. So there wasn't really time for the usual in-depth, thorough review. The plan was to focus on application-level issues until I realized that there were serious low-level configuration problems. Aman - I can't say too much about the test; but I think that the topic list they posted is a good starting point. Like I said I think that if you're pretty familiar with Linux then I don't think it should be too difficult. Also, it's all multiple choice so good test-taking skills will benefit you a lot; for example, sometimes the phrasing of one question can give you clues about the answer to another question if you pay close attention. Good luck! Hemant –

Did you start going into AWR strictly because your first SQL session indicated that something was very wrong with performance ? Your findings to date are server level -- although you have gone "from the inside out", I guess most DBAs would have started with server side statistics first. I think it was that first SQL session that made you dig into the database performance views first ? Hemant The engagement started off as “health check”.
