Vivek,
Is the application normally on a different server from the database?
YES. APPlication server is a different machine vis-à-vis the DB Server.
If they are normally separate, then using a different server for one piece
won't change your result.
COULD YOU EXPLAIN PLEASE?
But if they are normally on the same server, then benchmarking them on separate
servers will add a network delay.
NOT Applicable.

Qs. 1 What is the impact on Database Performance of Kernel Tuning Parameters in
Solaris 10, AIX 5.3?
Scenario:-
We the Software Product Vendor need to INTERNALLY do a comparative performance
benchmark between a Lower Application/Oracle Version & a Higher
Application/Oracle version to check for performance gain.
Qs 2 While the customer has BOTH APP & DB Servers on SUN what would be the
impact of us internally benchmarking with SUN APP Server but with AIX DB Server?
Is this approach advisable or a definite NO-NO?
NOTE - Currently a SUN DB Server is NOT available internally though it will be
shortly from now.
NOTE - Any Kernel parameter Tuning for performance that we carry out on the AIX
DB Server during the benchmark Runs may NOT be translatable directly to SUN at
Customer Site.
Thanks indeed
