Hi All,

I am using DB2 UDB enterprise server unlimited edition on linux
platform. We have completed entire database as well as front end (web
application in JSP using JBOSS) development. Its all working fine. We
will be deploying this in production server very soon. But as this is
my first project with respect to DB2 UDB i am little bit concern about
different database level, instance level and system level setting on
database server. Here if any body is knowing which parameter and which
settings need to be considered please let me know because i am in
urgent need of this. I tried to read different book but i didnt got
anything specific. I want ti go for setting with respecty to concurrent
user, heavy traffic on database server , different heap sizes etc.

Thanks
Suresh

Unfortunate it all depends. From what I understand you have not
performance tested your application before going into production? If
so, my best advice is to setup such a test. Try figuring out which work
flows are most critical, and stress test those. From there you should
be able to detect bottlenecks in both DB2 (different settings, bad sql,
missing index, etc) and JBoss (different settings, inefficient code,
etc). You might find the following article interesting. It is a bit
old, but I think it is still relevant:
