If transactions invoke MQ APIs, an MQ XA resource definition must be associated with the region to enable CICS to connect
               to the required MQ queue manager to which the APIs will be targeted. An MQ XA resource definition can be associated with a
               region at either the SIT or region startup file level. When specified in both the SIT and region start-up file, the region
               startup file takes precedence. To associate an MQ XA resource definition with a SIT: 
               	 
            
 
            	 
            
               -  
                  		  Open the resource definition file using the 
                     			 Enterprise Server for .NET Administration UI's CICS Resources File Editor 
                     		   
                  		
               
-  
                  		  Select the SIT you want to configure in the 
                     			 Results pane. See 
                     			 1 in the diagram below. 
                     		   
                  		   A properties window is now displayed to the right-hand side of the 
                  			 Results pane. 
                  		   
                  		
               
-  
                  		  Locate the 
                     			 MQ category in the properties window and enter the MQ XA resource definition name that you want associated with the SIT as the
                     value of the 
                     			 MQ XA resource name property. See 
                     			 2 in the diagram below. 
                     		   
                  		
               
-  
                  		  Choose 
                     			 , or click the 
                     			 Save icon in the toolbar to save the file. See 
                     			 3 in the diagram below. 
                     		   
                  		    
                  			 
                   
                     			 
                     
               
               		
               You must cold-start the region for the changes to take effect.
