Title: Performance tuning Cognos 10.2.2
Post by: vincydza@gmail.com on 01 Feb 2017 10:26:35 AM
Hi,

IBM recommends the below configuration for best performance of cognos environment, where can I make these changes in Cognos. Are these just guidelines for sizing of RAM on the server. are any of these setting related to  Cognos service setting "Max memory for Websphere Liberty Profile in MB'  in Cognos Configuration.

Is there a how to guide for setting up the below configuration.

2 GB for the base operating system and accompanying software, such as antivirus, back up, and enterprise management software
4 GB for a 64-bit Content Manager JVM
4 GB for a 64-bit Application Tier JVM
2 GB for the graphics JVM (IBM Cognos Workspace)
2-4 GB for the query service (dynamic query mode) JVM
1 GB per core for the report services processes (dynamic query mode) (JVM)
2 GB per core for the report services processes (compatible query mode) (BIBuS)

Please Advise

Vincent

The information appears to me to be server sizing information.

Performance sizing and tuning is going to depend heavily upon your environment - concurrent users, what those users do (report size and complexity, adhoc reporting, analytics, etc.), data sources, configuration of the server itself, etc. If you contact your IBM sales rep, they can provide a technical resource (perhaps free) to help you tune your particular environment.

This is generic memory sizing.
