               - Open the region start-up file using the 
                  			 Enterprise Server for .NET Administration UI's Region Startup File Editor. 
                  		  
               
- Select the 
                  			  node in the 
                  			 Results pane. 
                  		  
                  A properties window is now displayed to the right-hand side of the 
                     			 Results pane.

                     			  System Catalog Location properties will have been changed to <Using shared catalog>. 
                     			 
                      Note: If the
