Thanks Zhu Chao for the info.
1 Question - If you mean CPU usage DOUBLED when using Shared Servers
with RAC ?
A basic Qs - Is setting up shared servers for RAC similar to it's setup
for single instance (NON-RAC) ?
Any Good Docs, Links, Books, metalink Doc IDs, Pointers to Oracle
Documentation for Performance with RAC?
I will periodically send e-mails on our progress though the benchmark is
tentatively planned to start after about 1 month.
Regards

hi,
You might want to try dedicated server, to compare with shared server.
We hit severe capacity problem when we change from dedicated server to
shared server. CPU usage simply doubled. Dispature used half of total
cpu, which is a great overhead.
However we are running on 9205/solaris8. But I think basicly they
should be same.
If you can get some benchmark between shared server/dedicated, please
drop me an email. Oracle is saying to provide us with patch for that
problem , And I am interested in how it is doing on oracle 10.
Thanks
