Workload Considerations and Capacity Planning
To determine your present and future workload and system capacity needs, consider the following:
Existing and forecasted workload characteristics for at least a three-year time span
Distribution of transactions by type and over time
Different workload classes affect sizing
Session duration and characteristics differ significantly among classes
Make sure that you allow enough room in all areas of your PPM configuration for future growth. If possible, create a system that can meet the needs of your organization three years from now.
The memory capacity made available on the heap for a set of PPM application users can be controlled by increasing the:
Amount of memory allocated to the heap
Number of nodes in the server cluster that support user workload
Because of per-process memory allocation limits on most operating systems, there is a limit to which you can increase the size of the heap. The preferred way to grow PPM capacity on the application tier is to add nodes to a server cluster.
