UGMD_PROF - Profile Parameter Setting

BAL Application Log Documentation   BAL Application Log Documentation  
This documentation is copyright by SAP AG.

The Master Data Framework requires suitable settings for certain profile parameters. Wrong settings will most likely cause problems, such as terminations or memory bottlenecks.

This involves the following profile parameters:

• abap/shared_objects_size_MB : This parameter determines the size of the memory area in which the ABAP Shared Objects areas are created. This parameter is stored in the memory layout of the application server and can not be changed dynamically. For more information, see the documentation of this parameter directly in parameter maintenance RZ11.

If necessary, further parameters may be added here in the future.

The profile parameters must meet the following requirements for the Master Data Framework. Keep in mind that other application layers may have their own requirements, in which case the parameter values you choose will have to reflect a suitable compromise.

• abap/shared_objects_size_MB : You should reserve about 200 to 300 megabytes of Shared Objects memory for a medium-sized system for the Master Data Framework. This is merely a rough benchmark. This value increases by requirements for other software layers (for example, Basis, BW, or SEM), for which noassertion can be made here. For more information, see the documentation of the respective software layer. If a memory bottleneck should occur, you can readjust the parameter later on.

Make suitable settings for the profile parameters discussed on all application servers and restart the servers.
