48 Chapter 4 Configuring Clusters

Introduction to ClusterCATS Administration

ClusterCATS consists of these components:

• ClusterCATS Server

• ClusterCATS Explorer and ClusterCATS Web Explorer

• ClusterCATS Server Administrator and btadmin

The following sections describe these components.

All the components are installed on a computer when you run the ClusterCATS

installation program.

You must run the installation program on each server that will be part of your cluster, and

on the Windows computer from which you will use ClusterCATS Explorer to administer

the cluster. Even if your clusters run on Solaris or Linux platforms, you can use a

Windows computer to run 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, 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 JRun or ColdFusion server load

• Provides failover support for every server in your cluster

• Proactively monitors JRun and or ColdFusion servers and applications

ClusterCATS Explorer (Windows only)

ClusterCATS Explorer is a Windows-based administration utility that you use to create

and manage clusters from one computer. 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

• Configuring e-mail-based alarm notifications

• Monitoring clusters
