Before You Install ColdFusion Server 143
Internal
Note
Do not set up any internal round-robin entries. Also, static IP addresses are
recommended in lieu of dynamic IP address when clustering behind any
load-balancing or translating hardware.
5 You should test name resolution using the following diagnostic tools:
6 Create the cluster using the Cluster Creation Wizard. Enter the FQHN for each
server in the cluster, its maintenance address, and so on.
7 Enter the external round-robin names in the Web site alias field in the
ClusterCATS Explorer. Select Start > Programs > ColdFusion Server 5 >
ClusterCATS Explorer. Right-click on the cluster > Configure > Administration >
Load Balance > Website Alias.
8 Test fail-over by restarting either server and trying to hit either server with a Web
browser. Hit the round-robin name and test its ability to serve.
Note
If you are using static IP addresses with ClusterCATS fail-over, the failing server
encounters an IP conflict upon recovery and restarts to reclaim its IP address.
