rdisp/PG_SHM: Paging Buffer Size

Use

This value specifies the size of the paging buffer in 8 KB blocks. Since Release 4.0, a paging buffer is no longer necessary for SAP Memory Management because internal tables and lists are not located in the R/3 paging.

Goal:

Value = 0, to save swap space

Activities

Unit: 8 KB

Default value: 0

Recommended value: UNIX: 1000, but the value depends on the server size and the host system. You can find the values in the configuration examples (Contents button). For more information on Windows NT, see Parameter Overview for Windows NT.

Absolute upper limit: 250000 blocks (2 GB) for special applications (file system must be large enough)

Changes: The customer can make changes.
