Chapter 12 Configuring ColdFusion Clusters

Introduction to ClusterCATS Administration

ClusterCATS consists of three components:

•

ClusterCATS Server

•

ClusterCATS Explorer and ClusterCATS Web Explorer

•

ClusterCATS Server Administrator and btadmin

The components are described in the sections that follow.

All of the components are installed on a machine when you run the ClusterCATS for 
ColdFusion installation program.

You must run the installation program on each server that will be part of your cluster 
as well as on the Windows machine (NT, 98, or 95) from which you will use the 
ClusterCATS Explorer to administer the cluster. Even if your clusters run on Solaris or 
Linux platforms, you can use a Windows machine for running the ClusterCATS 
Explorer (recommended). You can also use the Web-based Explorer in conjunction 
with included server utilities to administer your clusters.

Note

Read the description of each component that is relevant to your installation in the 
sections that follow. These sections contain important configuration information.

ClusterCATS Server

The ClusterCATS Server is the heart of the clustering and load balancing of 
ClusterCATS. It must be installed on each server in your cluster. The server monitors 
the status of all other Web servers in a cluster and tracks application and transaction 
resource availability. ClusterCATS Server runs on Windows NT, Sun Solaris, and 
Linux platforms. To administer the ClusterCATS Server, use the ClusterCATS Server 
Administrator (Windows) or the btadmin utility (UNIX).

Each ClusterCATS Server component performs the following functions:

•

Intelligently manages HTTP load across Web servers

•

Proactively manages ColdFusion server load

•

Provides failover support for every server in your cluster

•

Proactively monitors ColdFusion servers and ColdFusion Web applications

ClusterCATS Explorer (Windows only)

ClusterCATS Explorer is a Windows-based administration utility that you use to 
create and manage clusters from a single machine. Using a Windows Explorer-like 
graphical interface, you perform management tasks, such as:

•

Creating and removing clusters

•

Adding and removing servers from a cluster 

•

Configuring load balancing and high availability features

•

Enabling administrator authentication privileges
