Configuration for UNIX / Windows NT in Memory Management

Prerequisites

Check if your host system fulfills the SAP recommendations regarding main memory and swap space.

Check the resources and system-specific requirements on all host systems on which an R/3 server is to be installed. For more information, see Checking the Hardware and Operating System of the Host System.

In Windows NT systems, the swap file is described as the virtual memory paging file. In the UNIX system, the term swap file or swap space is often used.

Procedure

Set the R/3 profile parameters that influence the memory management system.

Set these parameters in the instance profile that is used by the R/3 application servers in your system. For more information, see the CCMS Guide.

If you modify the profiles directly with a system editor, you must perform an error check. For more information, see Checking the Hardware and Operating System of the Host System.

The configuration of the memory management system depends largely on the number of users for each R/3 application server. Various configurations are described in the following units:

Application Server with Up to 15 Users

Application Server with Up to 50 Users

Application Server with Over 50 Users
