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: 
	 
 
	  
		- On the home page of Enterprise Server Administration, click 
		  Edit next to JCLDEMO. 
		
-  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. 
		   
- 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 |  |  
 
 
- Click 
		  OK, and then click 
		  Home to return to the Enterprise Server Administration page.
