Enabling load balancing for a group director

Edit online

This section describes the method to enable the load balancer for a group directory.

Procedure

  1. Use the MODIFY PARM command to set the following parameters that are located in the Data Virtualization Manager configuration member, AVZSIN00: 
    if 1 = 1 then
  do
    “MODIFY PARM NAME(GROUPNAME) VALUE(NULL)”
    “MODIFY PARM NAME(GROUPDIRECTOR) VALUE(YES)”
    The following table lists the parameters for configuring load balancing:
    Parameter Description Valid values
    GROUPNAME

    Controls the group that the current instance belongs to. All instance that belongs to the same group (that is, have the same GROUPNAME) automatically load balance among each other. If this value is not set, then the current instance does not belong to a group.

    		 Null
    GROUPDIRECTOR

    Indicates that a member of the group takes the role of director.
    YES
    NO
    Default value is NO.
  2. Ensure that everyone connects to the instance that is the group director.
  3. Add extra Data Virtualization Manager server subsystems, and set the maximum number of connections in each.
