Solution

Important: All these settings/configurations are required to be done on the second instance (the other instance that is on another drive)

1. Stop Tomcat for the FNCI instance that you want to configure.
   
   
2. Open the following file for that instance:

   <FNCI_INSTALL_DIR>/tomcat/conf/server.xml

    
3. Locate the Tomcat server port configuration and change the port to an available port.
   For example:
   <Server port="8005" shutdown="SHUTDOWN">
    
4. Locate the HTTP connector and configure it to use an available port.
   For example:
   <Connector port="9999" protocol="HTTP/1.1"
    
5. Locate the AJP connector and configure it to use an available port.
   For example:
   <Connector port="8084" protocol="AJP/1.3" redirectPort="8443" />
    
6. If the redirectPort also conflicts with a port used by another instance, configure an appropriate available redirect port.

    
7. Save server.xml.

    
8. Restart Tomcat.

    
9. Access the FNCI instance by using the HTTP connector port configured for that instance. For example, if you configured port 9999, use port 9999 when accessing FNCI.
