Affinity factor example two

• PASA and PASB are running with ACONCICS=YES set in their respective BBISSP00 parameter members.

• PASC is running without an ACONCICS= parameter (the same as ACONCICS=NO).

• All BBI-SS PASs are running with DYNTGT=YES set in their respective BBISSP00 parameter members (indicating that TGTDEFs will be honored on the systems)

• CASA contains TGTDEFs relating PASA to CICS01–CICS30, PASB to CICS31–CICS60 and PASC to CICS61–CICS75

• The UBBPARM data set for PASA and PASB contains:

  • A BBIJNT00 member with no CICS entries

  • A CMRDTL00 member with an entry for each of the production CICS regions (CICS01–CICS60) only

• The UBBPARM data set for PASC contains:

  • a BBIJNT00 member with no CICS entries

  • a CMRDTL00 member with an entry for each of the test CICS regions (CICS61–CICS72) only

• CICS01–CICS60 do not use either the INITPARM SIT parameter or a BBIJNT00/BMCICS00 to indicate to the region which PAS it is to use.

• CICS61–CICS75 use an INITPARM SIT parameter to indicate to the regions that they are to connect with PASC.

Case 2.A—a new production CICS region (CICS52) becomes active

Because the CICS region does not have a directive to use a specific BBI-SS PAS, it places a request into the common communications request queue. This element is picked up by either PASA or PASB (PASC is not participating in AutoConnect), which determines that it should connect to PASB based upon the following accumulated affinity weights:

 1024
 -240
 3072
3826

 1024
 -240
 3072
 8191
12047

Case 2.B—a new production CICS region (CICS53) becomes active

The user wants the new CICS to be connected to PASA, so a directive of PASA is specified by using the INITPARM in CICS. CICS53 will connect to PASA based upon the following accumulated affinity weights:

 1024
  -240
 10240
 3072
14066

 1024
 -240
 3072
 8191
12047

Case 2.C—a new test CICS region (CICS66) becomes active

Because the CICS region has a directive to use a specific BBI-SS PAS, it examines the subsystem blocks for PASC and determines that it is not participating in AutoConnect. It then makes a direct connection to PASC.
