294 Chapter 12 Configuring ColdFusion Clusters
10 Click OK.
Once configured, ClusterCATS automatically sets the state of each cluster member to
Passive and provides the load balancing and high availability data it acquires to the
LocalDirector. The LocalDirector then actively manages HTTP traffic across the
cluster.
Using third-party load-balancing devices
Third-party load balancing devices will actively distribute load to the Web servers
based on packet flow while ClusterCATS monitors ColdFusion load and availability. If
ClusterCATS detects that the ColdFusion server is becoming overloaded, it will
supersede the load balancing device and redirect traffic accordingly.
This section describes how to configure a third-party load balancing device with
ClusterCATS in the following sections:
• “Using third-party load balancing devices in Windows” on page 294
• “Using third-party load balancing devices in UNIX” on page 295
Using third-party load balancing devices in Windows
To integrate ClusterCATS with a third-party load balancing device:
1 Configure the load balancing device or software product as recommended by the
manufacturer.
2 Open the ClusterCATS Explorer and select a cluster.
HTTPS Port Enter the port number on which each cluster member
listens for secured HTTP requests. Enter 0 if not
applicable.
Bind ID Enter the same Bind ID specified for the explicit (real)
servers on the LocalDirector in step 4. In order for the
ClusterCATS/LocalDirector integration to work as
intended, the server name, port number, and bind ID
combination must be the same on this ClusterCATS
Load Balance tab as it is on the LocalDirector box.
