A cross-region database facilitates functionality that is used across more than one enterprise server region. 
               	 
            
 
            	 
            Specify the ODBC driver setup for the cross-region database: 
               	 
            
 
            	  
            	  
            	  
            	 
             
               		
                Open the 
                  		  .odbc.ini configuration file and add an entry for the cross-region database data source: 
                  		
               
 
               		[PG.CROSSREGION]
Driver = <driver-name>
Servername = <server-name>
Port = <port-no>
Database = $XREGN$
 
               		 where: 
                  		
               
 
               		
                
                  		   
                  			 
                  - <driver-name> 
                     			 
                  
- Specifies the name of the driver as configured in the 
                     				odbcinst.ini file; in the example above, that would be PostgreSQL. 
                     			 
                  
- <server-name> 
                     			 
                  
- Specifies the name of the server on which the database instance resides. 
                     			 
                  
- <port-no> 
                     			 
                  
- Specifies the port on which the database is listening, typically 5432. 
                     			 
                  
-  $XREGN$ 
                     			 
                  
- Specifies the name of the cross-region database, and is always this value.
