Adding an Additional Substation ES CICS Interface

You can add an additional Substation ES CICS Interface connection to a CICS region.

1. Add the Substation ES CICS resource definitions to the CICS region if this has not yet been done.
   • Repeat the step of the CICS Installation that updates the CSD.
   • Assign the correct CSD file to your JCL definition.
2. Create a new Substation ES CICS interface member by copying the default CICS SIP member located in USERHLQ.INTF(SXCINTF) to a new name.
   This new member must have a different INTF-ID keyword value. If connecting to a different CICS region, the APPLID keyword value must be changed.
3. Edit the Substation ES SIP member.
   The default member is USERHLQ.INTF(SXSSIP$1).
4. Add a new INTF-MEMBER keyword, specifying the newly created CICS member as the keyword value.
   For example: INTF-MEMBER=NEWINTF
5. Go to the Substation ES configuration panels, Option 4, and add the interface to the existing list.
   Note:

   • Ensure that the interface Id is the same as specified in the interface member.
   • Never use identical CICS INTF-IDs within a single region of Substation ES.
