Using RVDQ with Multiple Substation ES Instances

This section describes the process taken to configure multiple Substation ES instances to use RV distributed queue processing to communicate with a single CICS region.

The following steps configure three Substation ES instances:

Procedure

  1. Create three CICS SIP members, specifying the same INTF-ID for each.
    This INTF-ID must match the Interface Id defined in the ESB configuration file (on the Define Processing System Resources panel, option 4).

    In this example, the new CICS SIP members are named SXCINTF1, SXCINTF2 and SXCINTF3.

  2. Create three RV ESB SIP members, setting RVDQ-YN set to Y for all three. Each must also have a unique INTF-ID.
    In this example, the new RV ESB SIP members are named SXSIRV1, SXSIRV2 and SXSIRV3.
  3. Optional: Create three copies of the Substation ES SIP for Admin interface members. Name the copies SXSIADM1, SXSIADM2 and SXSADM3. In each new member, specify the corresponding ESB INTF-ID from Step 2 to each new ESB-INTF-ID keyword value.
    Note: This step is required only if Substation ES Heartbeat communications is used.
  4. Create three Substation ES SIP members, specifying a unique SUBSTATION-ID for each, and entering INTF-MEMBER settings for the corresponding CICS SIP and RV ESB SIP members that were created in Step 1 and Step 2.
    In this example, the new Substation ES SIP members are named SXSSIP$1, SXSSIP$2 and SXSSIP$3:
    • SXSSIP$1 has the INTF-MEMBER for SXCINTF1, SXSIRV1, and SXSIADM1.
    • SXSSIP$2 has the INTF-MEMBER for SXCINTF2, SXSIRV2, and SXSIADM2.
    • SXSSIP$3 has the INTF-MEMBER for SXCINTF3, SXSIRV3, and SXSIADM3.
  5. Create three SSP members, specifying the SIPMEM setting for the corresponding Substation ES SIP members that were created in Step 4.
    In this example, the SSP members are named SXSSSP$1, SXSSSP$2 and SXSSSP$3:
    • SXSSSP$1 has the SIPMEM for SXSSIP$1.
    • SXSSSP$2 has the SIPMEM for SXSSIP$2.
    • SXSSSP$2 has the SIPMEM for SXSSIP$3.
  6. Create three Substation ES startup JCL members, using the same ESB configuration file for all three.
    In this example, the Substation ES JCL members are named TIBSSES1, TIBSSES2 and TIBSSES3:
    • In TIBSSES1 specify PARM='-SSPMEM SXSSSP$1’.
    • In TIBSSES2 specify PARM='-SSPMEM SXSSSP$2'.
    • In TIBSSES3 specify PARM='-SSPMEM SXSSSP$3'.
  7. Start all Substation ES instances.
    All instances use RV distributed queue processing. The first started Substation ES instances acts as the scheduler.
