Enterprise Server for .NET provides support for the most commonly used IBM batch utilities. For each supported utility, 
               		Enterprise Server for .NET provides a corresponding program (an alias) that emulates the utility's functionality. The aliases 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. 
               	 
            
 
            	 
            The 
               		
Enterprise Server for .NET Administration UI also provides the 
               		
Program Aliases view to allow you to see what program aliases are in effect for a region in a running system. From this view, you can add,
               modify or delete entries, but you should do so with extreme caution as the behavior of your batch applications could be adversely
               affected. 
               		
               
Note: Changes to entries in the 
                  		  Program Aliases view are preserved across region warm-starts, but will be lost when the region is cold-started unless you have made the corresponding
                  changes to the region start-up file.
