# Customizing IMS Interface

To install the IMS components for Substation ES, you have to customize IMS Interface by editing the data sets and selected members listed in the following steps. You must follow the instructions in the members and submit them for execution.

## Procedure

1. Update the Substation ES IMS Interface SIP member.
   Before starting Substation ES, specify the correct values of the SIP of Substation ES IMS Interface. Before starting the default Substation ES procedure, validate the values of the following keywords.
   Keywords:

       APPLID     =IMSAPPL
       XCF-IMSGRP =SXIXCFGR

   For a description of the keywords, see IMS Interface Parameters.

   Data Set: `USERHLQ.PARM`

   Member: `SXIIIMS1`

2. Activate IMS Interface.
   Activate the interface by uncommenting the appropriate `INTF-MEMBER` keyword in the SIP member.

   Data Set: `USERHLQ.PARM`

   Member: `SXSSIP$1`

3. Optional: Using Customized HUB for TIBCO System Logger
   By default, the IMS Message Processing region uses the system default HUB, the default value is the SMF ID of the LPAR. To use a different HUB, add a DDName statement to the Message Processing region startup JCL in the following format:

   `//HUBxxxx DD DUMMY`

   where xxxx is the name of the HUB which you want to use for this Message Processing region.

   Data Set: `IMS.JOBS`

   Member: `MPRJOB`

   For more information about the Mainframe Logger usages, refer to the TIBCO Substation ES Mainframe Logger User's Guide.
