On the DualShield server, open the file below in a text editor such as Notepad++
C:\Program Files\Deepnet DualShield\tomcat\conf\server.xml
Find the XML element block that contains "jdbc.SQLServerDriver"
In the value of the "url" attribute, change the SQL server address to the address of the secondary SQL database server, aka the subscriber.
In the example above, replace "sql104" with the address of the secondary SQL database server, e.g. "sql105"
Save the server.xml after the change. Then, restart the DualShield service on the secondary server machine.
