Changing A Server's State; Restricting A Server From Participating In A Cluster - MACROMEDIA COLDFUSION 4.5-ADMINISTRING COLDFUSION SERVER Manual

Changing a server's state

All cluster members are added to a cluster in Active state by default. In Active state,
ClusterCATS provides availability and failover services to your Web resources. From
time to time, you may want to turn off these load balancing and failover services to
help you troubleshoot problems or to add additional servers to the cluster. To do this,
you can change the cluster's state from Active to Passive. In the Passive state, clusters
do not actively manage load nor protect against resource failures. Any HTTP requests
sent to a server that is in the Passive state are passed directly to that server without any
ClusterCATS processing.
To change a cluster member's state from Active to Passive:
1. Open the ClusterCATS Explorer, select a cluster member, and choose State from
the Configure menu. Alternatively, you can right mouse click the cluster member
and choose Configure>State.
The Server Properties dialog box appears.
2. Select the Passive Member option.
3. Click OK.
The color of the cluster member turns white, indicating that the cluster is passive.
4. Repeat steps 1 through 3 to change other members in the cluster.
5. To re-activate cluster members, select the Active Member option from this tab and
click OK.

Restricting a server from participating in a cluster

ClusterCATS lets you stop an active cluster member from receiving any HTTP requests.
You may want to restrict an active server when performing server maintenance or
