Memory settings

Memory settings depend on many factors, such as the level of activity that is expected on the server, 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. For more information, see IBM Cognos Analytics services (www.ibm.com/software/analytics/cognos/services/).

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

Cognos PowerPlay in virtualization environments

Cognos® PowerPlay® works as expected on most virtualization technologies. If the image is properly configured and tuned for Cognos PowerPlay applications, the performance and scalability can be similar to Cognos PowerPlay applications on physical hardware. Under higher loads, the VM instance might require a slightly higher number of cores than a physical hardware environment. If you are moving to a VM environment add 20 - 40% more cores to ensure that high peak load performance is not affected.
