To define a job number range to be used by a JES region: 
               	 
            
 
            	 
             
               		 
               		  
               - Open the region start-up file using the 
                  			 Enterprise Server for .NET Administration UI's Region Startup File Editor. 
                  		  
               
- Select the 
                  			 Region node in the 
                  			 Results pane. 
                  		  
                  A properties window is now displayed to the right-hand side of the 
                     			 Results pane. 
                     		  
                   
- Locate the 
                  			 Job Numbers category in the properties window and select whether you want the region to use 5 or 7 digit job numbers by setting the 
                  			 Restrict job numbers to 5 digits property value accordingly. By default the minimum job number used by the region is 1000. When you toggle the 
                  			 Restrict job numbers to 5 digits value between 
                  			 True and 
                  			 False, the default maximum job number used by the region toggles between 99999 and 9999999. To override the default minimum and
                  maximum job number values, modify the values associated with the 
                  			 Minimum Job Number and 
                  			 Maximum Job Number properties. 
                  		  
               
- Click 
                  			 , or click the 
                  			 Save icon on the toolbar to save the file. 
                  		  
               
You must cold-start the region for the changes to take effect.
