long report time-out issue

[dfite]

I am having a time-out issue when one of my long-running (about 2 hours) reports is run thru our application (it works just fine when run on the cognos server itself).  Does anyone have any ideas on what settings I can adjust to fix this?  I don't know if its even related, but I did find one configuration setting that was set to "Small Configuration" with text that says it is suitable for demonstrations, etc. where response time is more important than performance and/or memory is limited".  This was in our production environment!  I can;t seem to find a way to change that setting, though.  Any ideas?

Thanks!

you can change small to medium configuration, also increase buffer size from 4 to higher number.
Even though a lot of settings depend upon what you have, go through administration guide for best settings in general.
