Define Batch Initiators and Printers

JCL execution requires 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 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 an INITALL initiator. You need to create a new one for your application, named INITB.

To define an initiator to start 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.

   You can see that an initiator, INITALL, has already been defined.

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.
