Create a Highly Available Dispatcher

NOTE: Before beginning,  configure the two load balancers (LB) exactly the same in order to allow failover and continued service.

From the Primary Load Balancer gui (Start > Program Files > IBM WebSphere > Edge Components > Load Balancer for IPv6 > Load Balancer for IPv6 ):

1. Right click on the Dispatcher and click Connect to host…
2. Connect to the :10099
3. Right click on the High Availability icon and select Add Heartbeat…
4. Leave the local machine’s IP addres in the first textbox and enter the secondary LB’s IP address in the second and click OK.
5. Right click on the High Availability icon and select Add High Availability Backup….
6. Set the role as Primary, the IP of the secondary server and the port number 10099.
7. Repeat the same process for the secondary LB except select Backup for the servers role.
8. Once complete click the refresh statistics button and confirm the state changes to: Synchronized .
9. Once the process is complete it is important to edit the goActive and goStandby scripts.
   1. These files can be found in the <edge_home>/lb/servers/samples directory.
   2. Follow the instructions within each script file, editing the set CLUSTER,INTERFACE and NETMASK values.
   3. Copy both scripts into the lb bin directory at: <edge_home>/lb/servers/bin/
   4. ensure that you remove the .sample after the filename so they read goActive.bat and goStandby.bat

If you wish to test your configuration. Disable the network addapter on the primary LB and watch the secondary change into active state. Did your service remain available?
