Hi!
Oracle Performance Tuning 101 eBook (by Gaja, Kirti and John Kostelac) is
available to download in PDF from http://www.veritas.com/offer?a_id=3805
Btw, veritas has a free SQL Server tuning book on their site as well.

Avnish,
The book goes through this a bit on p61. There are a few tools out
there, including three from Oracle. As I mention in the book, I use our
own Hotsos Profiler, described at www.hotsos.com/products/profiler.html.

Thank you for your in-depth response. It was very helpful. To me, the
hardest books to read and understand are those that tell you WHAT but not
WHY. From the excellent reviews I've received (look at MLaden's review just

wrote it. He definitely knows what he is doing. There are quite a few people
on this list who can attest to that.

This is where the balancing comes into picture. If it is a bulk Insert then

Vivek - Hopefully you will receive some replies from someone with RAC
experience. However, since RAC is so new, the information on tuning it may
be pretty slim. Since RAC is based on Oracle Parallel Server, you might
consider searching for tips on OPS. Some tips might apply to RAC.

Dick ,
Thanks a ton for ur feedback. I ran UTLBSTAT/UTLESTAT and found out that the problem was with memory. Then I went and queried V$SGASTAT, V$SQLAREA, V$SQLTEXT. Can u tell me if there can be any other problems ? I found out later that there were some indexes added afterwards.
Thanks nyways.
