# Receiving the Initial Installation File

After the Substation ES initial installation file is transferred to the z/OS host, you must receive the initial installation file on the z/OS host.

The USERHLQ.XMIT.INST file contains the JCL required for receiving other files and for creating the appropriate libraries for TIBCO Substation ES. To complete this process, you have to substitute the appropriate site-specific user values with the TIBCO-supplied variables.

## Procedure

1. In the ISPF Command Shell panel, type the following command to receive a file that contains the JCL required to begin a first-time installation:
   receive inda('USERHLQ.XMIT.INST')
   The following message is displayed in TSO:

   INMR906A Enter restore parameters or 'DELETE' or 'END' +

2. Type the following command to customize the installation JCL:
   DA('USERHLQ.INSTALL')
   After the installation JCL is received, the following message is displayed:

   INMR001I Restore successful to dataset 'USERHLQ.INSTALL'

   where USERHLQ.INSTALL is populated with the members that are required for continuing the installation.
