D XCF,GROUP,DFHIR000,ALL command does not display all CICS members

Technote (troubleshooting)


Problem(Abstract)

You enter command D XCF,GROUP,DFHIR000,ALL from the system console to determine if all CICS region APPLIDs (APPLID is used as the MEMBER NAME when joining an XCF group) have joined the DFHIR000 group. You expected to see all CICS APPLIDs because all regions show the connection INSERVICE when using a CEMT INQUIRE CONNECTION command.

Cause

The inter-region communication (IRC) facility is not open in all CICS regions.

Diagnosing the problem

The CICS regions not showing up as joined members of the DFHIR000 group in the results of the D XCF,GROUP,DFHIR000,ALL command were found to have IRC closed. The result of CEMT INQUIRE CONNECTION being inservice or not has no relationship to whether or not the region has joined the XCF group. CICS joins and leaves the XCF group by using IXCJOIN and IXCLEAVE, which are done upon logon and logoff to DFHIRP. Logon and logoff to DFHIRP happens at OPEN and CLOSE of IRC respectively.

Example of the beginning of a display command:

IXC333I  15.05.30  DISPLAY XCF 772                  
   INFORMATION FOR GROUP DFHIR000                  
   MEMBER NAME:        SYSTEM:     JOB ID:    STATUS
   CICSHA61            MV26        CICSHA61   ACTIVE
   CICSHA62            MV26        CICSHA62   ACTIVE
   CICSHC61            MV26        CICSHC61   ACTIVE
   CICSHC71            MV27        CICSHC71   ACTIVE
   CICSHT61            MV26        CICSHT61   ACTIVE
   DEWCB9C0            MV2C        CMASC9C0   ACTIVE


Resolving the problem

Make sure IRC is open in any CICS region that you want to appear in the XCF display. CEMT INQUIRE IRC will show you the IRC status and CEMT SET IRC will allow you to open or close the IRC facility.
