By using the following parameters, you can limit the maximum use of the process-specific memory. This in turn limits the maximum use of swap space by an SAP application server.
Consider the following parameters:
Limits the amount of process-specific memory used...
...by any particular dialog work process
... by any particular non-dialog work process (background, spool, etc.)
...by an SAP application server -- all dialog and non-dialog work processes
You can find more information on the functions of these parameters under Limits for Allocating Heap Memory inFunctions of the SAP Memory Management System.
Normally, only background work processes use a large amount of swap space.
Dialog processes do not usually use a lot of swap space, as long as the following conditions apply:
The following generally applies: the more main memory that an application server has, the better the performance.
