Mulitple dispatcher on a single server

[Olivier]

Good morning,

I'm looking for some advices/experience on using servers resources (memory & cpu) by Cognos 8.
I have servers with 4 cpu (16 cores) and 24 gb memory on which Cognos 8.4.1 32 bits is installed (gateway + dispatcher + content manager).
At month closing we have some performance issues and I know that Cognos 8.4.1 32 bits won't use all the available resources (same as if all tuning settings have been applied).
As this server is dedicated for Cognos BI only and it is quite powerful (in terms of resources), I tought that it could be interesting to add another dispatcher on the server to process more requests.
But before going that way, I've some questions for those of you having experience with such installations :

• Is this a good approach ?
• Should I take care of something before doing the installation ?
• Do some of you have experience in doing this and what is your return on it ?

Note that we can't move to Cognos 10 at short term and I know that it would certainly help !

Thanks in advance for your answer

Olivier
