Changing Active/Passive Settings
All cluster members are added to a cluster with the ClusterCATS Server in Active state
by default. In Active state, ClusterCATS Servers intercept requests to your Web
resources and provide availability and failover services. From time to time, you may
want to turn off these load balancing and failover services to help you troubleshoot
problems. To do this, change the ClusterCATS Server’s state from Active to Passive. In
Passive state, ClusterCATS Servers 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 the Web server without any ClusterCATS Server processing.

To change a cluster member’s state:
1 Open the ClusterCATS Explorer and select a cluster member.
2 Select Configure > State. Alternatively, you can right-click the cluster member
and select Configure > State.
The Server Properties dialog box appears:
3 To have the ClusterCATS Server ignore incoming HTTP requests and pass them
directly to the Web server, select the Passive Member option.
4 To have ClusterCATS Servers intercept requests to your Web resources, select the
Active Member option.
5 Click OK to apply your changes.
The color of the cluster member’s icon in the ClusterCATS Explorer turns white,
indicating that the cluster is passive.
6 Repeat steps 1 through 5 to change other members in the cluster.
