# Starting Substation ES

After specifying all the required settings for establishing communications between Substation ES and a TIBCO messaging product, you can now start TIBCO Substation ES.

You can run the IVP tests or samples (or both) that relate to your environment to ensure that the connectivity, data transformation, message flow, and system operations are correctly installed and functional.

## Prerequisites

Ensure that the following conditions are met:

- The `USERHLQ.AUTH` library is APF-authorized.
- The Rendezvous daemon is running if you use TIBCO Rendezvous.
- The EMS server is running if you use TIBCO EMS and you can ping the EMS server from your host.

## Procedure

1. Activate Substation ES Interfaces.

   You must specify the Substation ES interfaces that are selected at startup. The default is that no Interfaces, which are commented out, are selected during a default startup.

   Data Set: `USERHLQ.PARM`

   Member: `SXSSIP$1`

   1. Edit the `SXSSIP$1` member to select the interfaces that are appropriate for your site.
      The interfaces section of this member includes the following `INTF-MEMBER` lines:
      - EMS ESB
      - Rendezvous ESB
      - CICS Interface
      - RED Interface
      - IMS Interface
   2. Uncomment the desired `INTF-MEMBER` lines.
2. Execute the Substation ES startup JCL.
   This member starts the Substation ES z/OS region. Do not submit this member until the following conditions are met:
   - All the installation steps for the required interfaces are completed.
   - The system startup parameters are validated.
   - The SIP is validated.

   Data Set: `USERHLQ.JCL`

   Member: `TIBSSES`

   If the interfaces are activated and Substation ES is started successfully, the job output similar to the following one is displayed:

       $HASP373 SXS2XX STARTED - INIT 6 - CLASS A - SYS LION

       SXG1801I Parameter Log closed

3. Execute the Substation ES IVP: TIBCO Rendezvous listener.

   Replace the Substation ES variables with the appropriate values. This member initiates a Rendezvous listener, which receives messages from the Substation ES region. The messages originate from a Rendezvous publisher that are executed by one of the Interface-submitted IVPs.

   Data Set: `USERHLQ.JCL`

   Member: `SXRGILS`

4. Execute Substation ES: Generic Error Listener.

   Replace the Substation ES variables with the appropriate values. This member (choose the Rendezvous or EMS member as appropriate) initiates a generic listener, which receives error messages from the Substation ES ESB.

   Data Set: `USERHLQ.JCL`

   Member:
   - `SXRRIELS` (for Rendezvous)
   - `SXJRIELS` (for EMS)
