After you install

When you have successfully installed ClusterCATS on all members of the cluster and any

administrative computers, you are ready to create your first cluster.

If you administer ClusterCATS from a Windows computer, you can use the Cluster

Setup Wizard described in “Creating clusters with the Cluster Setup Wizard” on page 54,

or manually create the cluster using the procedure described in “Creating clusters” on

page 54.

If you administer ClusterCATS from a UNIX computer, see “Creating clusters in UNIX”

on page 60.

Regardless of the method you use to create your first cluster, you should familiarize

yourself with the procedures in the following table when implementing your web

applications in a clustered environment:

Option Description

Load thresholds

for servers

Two response time thresholds configured for each server. THe first

defines maximum or busy load; the second activates load

management. If the load for the server exceeds the busy threshold, no

new sessions can start on that server. If another server in the cluster

has the capacity to handle additional users, requests are redirected to

it. The load management activation threshold is referred to as the

gradual redirection threshold and is designed to prevent the server

from reaching the peak threshold.

For more information, see “Server load thresholds” on page 66.

Email addresses

for alarm

recipients

ClusterCATS generates alarm notifications for several events,

including HTTP server failures, low disk space, server busy, and web

server failover. You provide e-mail addresses of all administrators for

ClusterCATS to notify for each generated alarm notification.

For more information, see “Administrator alarm notifications” on page

98.

Session-aware

load balancing

If your web applications use session variables that store information in

web server memory, you should enable session-aware load balancing.

This feature prevents users who have established a session from being

redirected to another server as a result of load balancing.

For more information, see “Session-aware load balancing” on page 72.

Administering

with the

ClusterCATS Web

Explorer

If you use a UNIX computer to administer your cluster with

ClusterCATS Web Explorer, you must configure your web server to

host the Web Explorer pages.

For more information, see “Configuring the communications port on

your web server” on page 50.

Administrative

authentication

Password protect administrative access to your cluster members using

domain accounts (NT only) or local accounts on each system (UNIX

and NT). Administrative users must also be members of the group sys,

or a special BT_<clustername> group.

For more information, see “Administering security” on page 103.
