How to Specify Update Server Name if Load Balancing is Deactivated

In the standard system, this parameter, rdisp/vbname 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 ). You need to specify the name of the update server that is to process the updates if load balancing is deactivated ( rdisp/vb_dispatching = 0 ). 

Go to RZ10, select Instance Profile & Extended Maintenance. Scroll to find & define the paramater rdisp/vbname .
