Note: We recommend that you use a connection string to connect to Db2 databases; that is, using the 
                  		  connect attribute within the database configuration file, which is covered in a later step (Update the Configuration File for DB2 Region and Cross-Region Databases). 
                  		
               
 
               		
               Use the following steps if you do not intend to use connection strings, but instead create ODBC data sources to access region
                  and cross-region databases.
