To use XDB Link with SNA: 
               	 
            
 
            	 
             
               		
               - Verify that VTAM is set up to allow independent LU6.2 access to host data. Have the VTAM systems programmer complete the VTAM
                  Worksheet. 
                  		
               
- Ensure that independent LU6.2 and 3270 support have been generated for the physical unit (PU) supporting XDB Link: 
                  		  
                   
                     			 
                     -  Create the PU. 
                        			 
                     
-  Create an independent LU definition. 
                        			 
                     
-  Create a mode entry that supports parallel sessions and is compatible with IBMRDB. 
                        			 
                     
 
Note: Do not discard the VTAM worksheet when you are finished configuring VTAM. It contains information that you will use to configure
               other parts of XDB Link.
