Activating Background Processing

Use

By default, background processing is inactive in the SAP System. To enable background processing, you must set up at least one CCMS operation mode to contain one or more background processing servers, SAP application servers with a minimum of two dialog work processes and one background processing work process. You need to perform these procedures only once for each background processing server that you set up.

Procedures

Define a background processing server by defining an SAP instance (an application server) with at least two dialog work processes and at least one background work process. This can be done in one of two ways.

1. Call Transaction RZ04 or choose CCMS
® Configuration ® Operation modes/instances.
2. To create a new operation mode, choose Operation mode ® Create. Name and define the new operation mode and save the definition.
3. To change an existing operation mode, select the operation mode you want to change and choose Operation mode ® Change. Rename or redefine the operation mode and save the new definition.
4. To review the current configuration of SAP instances and operation modes and begin setting up background processing servers, choose Instances/operation modes.
5. If the server you want to set up as a background processing server doesn’t appear in this list, create a new instance. Choose Instance ® Create new instance. Complete the instance definition in this Maintain Instance Data window, then save.
6. Once the server you want to set up as a background processing server appears in this list, select the mode for that server then select Choose. In the Maintain Work Process Distribution screen, set the number of work process by selecting the current number and increasing or decreasing it with the "-" or "+" buttons. Save here, return to the previous screen, and save again.

Alternative procedure:

1. Call Transaction RZ10 or choose CCMS
® Configuration ® Profile Maintenance.
2. Select the profile you want to edit, then choose Extended Maintenance and click Change. You should be able to identify the correct profiles by the host name of the server. Instance profiles follow the naming convention __, as in C40_D00_HOST1.
3. Set the parameter value of rdisp/wp_no_btc to the number of background work processes you want in the instance profile of each background server.
4. Restart the servers so that the changed profile parameter becomes effective.
5. Assign the background processing server(s) to at least one CCMS operation mode.

Background processing jobs can be processed only in operation modes in which at least one background processing server is active. If you are using more than one operation mode, you should assign your background processing server to all of your operation modes, so that background processing is always available.

Verify that your operation modes are active from CCMS ® Configuration ® Operation Mode Calendar then Display.
