                        			 Executing TSO Commands in Batch Mode (IDAEFT01), 
                           			 and

-  Specify the string that is passed to the resource manager on the xa_open() call. It usually contains at least the database name, and often the user ID and password credentials for connecting to the
                        database. The contents of this string are database-specific. 
                        			 
                        Where the RM switch module supports dynamic registration, and the database vendor requires the name of the module that provides

 Important: For more information on the syntax for 
                     			 Open string, see the 
                     			 xa_open string topic for your database type, listed below.

                  		  Add. 
                  		
               
Note: You cannot add an XAR until all the mandatory fields have values. If you add an XAR while the region is running, you can connect
               to it as soon as the XAR is enabled.
