Memory settings

Memory settings depend on many factors, such as the level of activity that is expected on the server, the complexity of the IBM® Cognos® applications, the number of users and requests, and acceptable response times.

If your environment supports more than 100 named users, is complex, experiences high peak usage periods, or includes any combination of these factors, consider completing a capacity plan.

To determine the settings that are best suited for your environment, performance testing is advised.

Finding memory requirements for your release of Cognos Analytics

Each Cognos Analytics release has a unique list of supported software and minimum requirements to help guide you when you are doing capacity planning. To see the memory requirements for your Cognos Analytics 11.2.x release, follow these steps:

  1. Go to the IBM Cognos Analytics on Premises 11.2.x Supported Software Environments page (https://www.ibm.com/support/pages/node/6440667).
  2. Find the table for your release. Then, under Requirements by type, click Hardware.

    A report lists the hardware requirements for each supported platform.

  3. In the Hardware column for your platform, find the Memory row and then read the associated requirement.
Example for release 11.2.4 FP3
If you are running Cognos Analytics 11.2.4 FP3 on Windows and follow the previous steps, a hardware compatibility report tells you that the Cognos Analytics server requires a minimum of 32 GB of RAM.
