This field is always present for each registered member, and is the only weight that the load balancer actually receives. It is calculated by applying the Communications Server weight as a percentage of the WLM weight, and then the weight is normalized within its group. Normalization involves reducing the weight values while largely preserving the ratios between the weights. Normalization is performed within a group only if there is more than one available member within the group. Net weights can be in the range 0 – 64. A higher net weight means that member is capable of receiving more work than a member within the same group that has a lower weight. There are certain situations where the net weight can be 0 when neither the WLM weight or the Communications Server weight is 0. This can happen if the member has been quiesced by the z/OS® operator or the load balancer. Conversely, there is one case where the WLM weight or the Communications Server weight can be zero, but the net weight is nonzero. This can happen if the net weight of every member in the group calculates to zero, and at least one member of the group is available. In this case, the net weights of all of the available members in the group are changed to 1 to force round-robin distribution among the members in the group, rather than to stop sending new workloads to the group entirely. Line 10 in Figure 1 shows an example of the NET WEIGHT field set to a nonzero value, while line 18 shows an example of the field set to zero.
