The aliases to be used by a region are defined in the region start-up file. The 
               		Enterprise Server for .NET Administration UI is used to view these definitions. You can add additional entries to this list, or change existing entries so that your own
               programs are used instead of the 
               		Enterprise Server for .NET defaults. To do this: 
               	 
            
 
            	 
             
               		 
               		  
               - Open the startup file of the JES region you are configuring, with the Region Startup File editor. 
                  		  
                   A window is displayed, showing the program aliases already configured for the region. 
                     			  
                     		  
                   
- To change the name of the program aliased to a mainframe utility, double-click the alias name and enter the name of the program
                  that you want it to be aliased to instead. For example, to change the alias for the IDCAMS utility from the default MFJAMS
                  to MYAMS: 
                  		  
                  Clicking away from the alias name in the grid will update its value. 
                     		  
                   
- To add a new program/alias definition: 
                  		  
                  
                     			  
                     				
                     - Click 
                        				  Add Program Alias. 
                        				
                        The 
                           				  Define Program Alias dialog is displayed. 
                           				
                         
- Enter the name of the utility program that you are defining in the 
                        				  Program name field, and the name of the program that it is to be aliased to in the 
                        				  Alias name field. 
                        				
                     
- Click 
                        				  OK to dismiss the 
                        				  Define Program Alias dialog and complete the creation of the definition. The newly created definition will now be displayed in the 
                        				  Results pane. 
                        				
                     
 
- You can remove a program/alias pair that you have added by selecting the item in the grid and clicking the 
                  			 delete key. 
                  		  
                  
                     			 
                     Note: System definitions cannot be deleted from a region start-up definition, so if you do not want one defined for the region,
                        select the item in the grid and check the 
                        				Omit column. 
                        			 
                      
 
- Choose, or click the 
                  			 Save icon in the toolbar to save the file. 
                  		  
               
               
               		You must cold-start the region for the changes to take effect.
