Situation Description

This situation is triggered when the aggregation status of the workload is not satisfactory. The aggregation status is an indication of the amount of replication information that has been received for a workload, as determined by the NetView program that is running on the controller system. The following values are valid:

  • SATISFACTORY: All capture and apply data has been received for the workload and is being used for aggregation.
  • UNSATISFACTORY: Incomplete capture or apply data has been received for the workload. Data has been aggregated using the available replication data, but the missing data might lead to inaccurate results.

 

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.
