Contents of the report

A Coupling Facility Activity report is produced for each coupling facility attached to the sysplex. Figure 1 gives an example of the overall structure of the Coupling Facility Activity report. It shows the sequencing of the report sections:

  • Coupling Facility Usage Summary
  • Coupling Facility Structure Activity
  • Subchannel Activity
  • CF to CF Activity

For a complete Coupling Facility Activity report, it is recommended to combine data from all of the systems in the sysplex. If data from one or more systems is missing, the Structure and Subchannel Activity sections of the report are incomplete. In addition, the PRIM (primary) and SEC (secondary) indicators of synchronously duplexed structures might be missing in the Usage Summary section because this information is gathered only on one member of the sysplex (sysplex master gathering).
