To configure the JES support for the enterprise server: 
               	 
            
 
            	 
             
               		
               - On the Enterprise Server Administration page, click 
                  		  Edit next to the JCLDEMO row in the table of servers. 
                  		  
                   This opens the 
                     			  page. 
                     		  
                   
- Select the 
                  		  MSS tab and then the 
                  		  JES tab. 
                  		
               
- If not already checked, check 
                  		  Job Entry Subsystem enabled. 
                  		  
                  Note: This should already be selected, because you used the JCL template to create the enterprise server.
