Main System Profile Parameters for Updates (SAP Library - Updates in the SAP System (BC-CST-UP))

Main System Profile Parameters for Updates

The following table contains an overview of the most important update parameters.

Note

Note that you normally never have to set these parameters manually. Generally speaking, the most appropriate value is the default parameter value; otherwise the parameters are set for you by the profile management function (for example, if you set the number of update work processes in an instance profile).

Parameter	Description
rdisp/vb_dispatching	Activates (1) or deactivates (0) update dispatching with load balancing. Load balancing is normally active. Do not change this value unless instructed to do so by SAP.
rdisp/vbname	Specifies the name of the update server that is to process the updates if load balancing is deactivated ( rdisp/vb_dispatching = 0 ). In the standard system, this parameter specifies the name of an update server (set when the update server is created). If rdisp/vb_dispatching is set to 0, the updates are only processed by the server in rdisp/vbname. If the parameter has not been set correctly (not to an update server), this is reported when the installation check is performed (transaction sick ).
rdisp/vb_delete_after_execution	Determines whether update records are deleted automatically after they have been processed successfully. In the standard system, this is set to 1 (automatic deletion activated). If set to 2, automatic deletion is deactivated. This value can be used to set the update and database performance. In this case, the report rsm13002 with the parameter DELETE = X should run in the background at least once a day to prevent the update tables from becoming excessively large. See also the section entitled Background Processing in the CCMS documentation.
rdisp/max_vb_server	Maximum number of update servers permitted in the SAP System. Default = 50 servers.
rdisp/vb_included_server	List of the SAP update servers, which are to be used to process updates in accordance with the load balancing principle. No updates are assigned to update servers that do not appear in the list. This parameter is empty in the standard system. This means that all active update servers are taken into consideration for the load balancing mechanism. This is generally speaking the optimum value.
rdisp/vbdelete	Specifies the number of days after which the update records are deleted. The parameter is set to 50 days in the standard system. Once this interval has expired, an update record is deleted irrespective of its status (processed, not processed, error etc.). If set to 0, automatic deletion is deactivated. This value should only be set temporarily, and only if an incorrect update record is to be kept for further analysis.
rdisp/vbmail	Specifies whether a user is to be informed via express mail that his update has been canceled. The parameter is activated (value = 1) in the standard system. If an update is aborted, the system sends an express mail via SAP Mail to the user that created the update. If set to 0, the express mail is not sent automatically.
rdisp/vbreorg	Specifies whether an update server is to search for incomplete update records and delete these. Update records can be incomplete - if a transaction registers one or more update components - as a result of a screen change in which the transaction that creates the update generates a database commit; the transaction, however, is aborted and a rollback is triggered. Incomplete update records are of no significance, but take up space in the database. Reorganization is, therefore, active (value = 1) in the standard system. You can deactivate reorganization by setting the value to 0. In this case, you should make sure that the report rsm13002 is run in the background at regular intervals to delete the incomplete update records (see also Background Processing).
rdisp/vbstart	Specifies whether update requests that have not been processed or not fully processed (status = run, V2 modules not processed, etc.) are processed automatically when an update server is started. In the standard system (value = 1), update records such as these are processed (status usually = auto) (see The Most Important Update Statuses). If set to 0, automatic processing is deactivated. The value of this parameter can normally only be changed by SAP.

Note

To obtain further information on the update parameters, enter the transaction code /nrz11 in the SAP System, and then search for the parameters whose names start with rdisp/vb .
