Configuration for UNIX

Prerequisites

Check that your host system fulfills the SAP recommendations for main memory and swap space.

Procedure

Profile Parameter

The ideal parameter settings depend on the hardware resources available (main memory and swap space) on the one hand, and the system load on the other, that is, the maximum/average number of (active) users working on an application server.

Default values of profile parameters are recommended by SAP. The default settings depend on which UNIX is used. Run report SE38 in transaction RSPFPAR to see the system and user-defined parameter values.

An application may terminate due to one of the quotas. You can increase the value of individual profile parameters.

  • ztta/roll_extension_dia: EM Quota for Dialog Work Processes

  • ztta/roll_extension: Quota for Extended Memory

  • abap/heap_area_dia: Heap Memory Limit for Dialog Work Processes

  • abap/heap_area_nondia: Heap Memory Limit for Non-Dialog Work Processes

  • abap/heap_area_total: Total Quota for Heap Memory

Swap Space

Configure sufficient swap space. SAP recommends 20 GB swap space for 64 bit systems.
