Configuring Update Groups (SAP Library - Updates in the SAP System (BC-CST-UP))

Configuring Update Groups

Use

In an SAP system, automatic load distribution (also known as dispatching) takes place even with asynchronous updates. Load distribution (Update Dispatching with Load Distribution) usually takes place across all of the available update work processes.

This global dispatching is, however, not always required.

To deal with this, application servers can be divided up into groups, and update requests are then processed within the group only. Update dispatching then takes place within the groups. Dispatching does not take place outside these groups.

Note

You can activate dispatching by setting the profile parameter rdisp/vb_dispatching to 1 (see also Main System Profile Parameters for Updates). If this parameter is set to 0, all of the update requests are sent to the server specified in the profile parameter rdisp/vbname.

The update groups have the following properties:

All application servers that are not assigned to any group represent the default group.
An application server can belong to only one group.
Every group has to contain at least one update server.

Procedure

The procedure for creating and changing update groups is described in the section entitled Server Groups Tab Page
