Short text
Load balancing for Update Servers

Parameter description
The dispatch of update requests occurs after a very simple procedure:

  • Each application server leads a list of active update servers and their
  • configured update work processes.
    • Every update server with the relevant content are assigned the update
    • requests dynamically (see parameter
      rdisp/vb_context or rdisp/vb2_context).
      • An update work process is assigned to all update work processes in a
      • disptach cycle. It is switched to the update server after everyassignment. This means, within a dispatch cycle a server is assigned asmany VB requests as update work processes are assigned for it.
        This parameter lets you determine the number of update work processesrelevant for dispatching, for example, to assign more VB requests tofaster servers. This number is determined by the current number ofupdate processes and the value of rdisp/vb_factor.
        After processing the U1 update requests, the U2 part is dispatched.
