NAS_AA_RW_ConsistencyGroups

Situation Description

This situation is triggered when not all of the defined consistency groups are being monitored.

The Defined Consistency Groups attribute indicates the number of consistency groups that make up the workload as defined by the replication product. The Monitored Consistency Groups attribute indicates the number of consistency groups for a workload for which the NetView program has data, which is to be used for aggregation. When the number of monitored consistency groups is less than the number of defined consistency groups, there may be partial data displayed in the Replication Workloads workspace.

 

Suggested Actions

For details, see the Aggregation State attribute. The Aggregation State attribute provides an explanation for the aggregation status value, as determined by the NetView program that is running on the controller systems. The following values are valid:

  • COMPLETE DATA - All capture and apply data has been received for the workload.
  • PARTIAL DATA - Not all of the capture and apply data is received for the workload.
  • STALE DATA - All of the capture and apply data for the workload is not received within a calculated window, which is based on the sampling interval as defined on the production system. The window value is the sampling interval plus the value of the ACTACT.MASTER.DELAY CNMSTYLE statement, which defaults to 3 seconds. For information about the ACTACT.MASTER.DELAY statement, see the NetView for z/OS Administration Reference.

The NetView program resides on the controller systems, and on the production systems in the sites where replication servers run. Verify that the NetView program that is running on the primary controller is configured as the enterprise master NetView program for Active/Active data.
