Define a Batch Initiator SEP

JCL execution uses the following types of Service Execution Processes (SEPs):

• Batch initiator (often abbreviated to simply "initiator") — for running JCL jobs
• Batch printer SEP (often abbreviated to simply "printer") — for sending the output from a JCL job to a printer

You can define initiators and printers to start up automatically whenever the enterprise server region is started, and you can also create ones that last only for the current session.

The JCL template that you used to create an enterprise server includes a default initiator named INITALL. You need to modify INITALL for your application.

To modify INITALL to be a class be initiator that starts automatically:

1. On the Enterprise Server Administration home page, click Edit next to JCLDEMO.
2. Make sure the Server and Properties tabs are selected, and click MSS > JES > Initiators.
3. Click Edit on the row for INITALL and change the initiator as follows:

   Field	Value	Comment
   Name	INITB	Not case sensitive – gets folded to upper case
   Class	B	Not case sensitive – gets folded to upper case
   Description	Initiator for class B job

4. Click OK, and then click Home to return to the Enterprise Server Administration home page.

This concludes the configuration of the JES-enabled enterprise server. Next, you need to create and build the JCL application that will run on the enterprise server - see Create and Build a JCL Application.
