4 Highly Available WebSphere Business Integration Solutions
1.3 Overview of the sample implementation
The sample WebSphere Business Integration solution that is examined in this
redbook is implemented under AIX® Version 5.2, Maintenance Level 1. The
supporting high availability cluster is implemented using HACMP™ Version 5.1.
The WebSphere Business Integration scenario is shown in Figure 1-1.
Figure 1-1 Scenario overview
The dashed box contains those components that are made highly available in the
example implementation.
The solution is implemented on two p-Series machines. The storage that these
machines share for high availability purposes is a FAStT Storage server. There is
a single HA cluster.

The basic scenario is implemented under three different takeover configurations.
This allows the authors the opportunity to achieve and explore a number of
different HA capabilities. The first configuration shows Active/Passive takeover.
The distribution of resources for this scenario implementation is shown in
Figure 1-2.

Two resource groups are implemented on node 2 to allow the authors to emulate
the existence of a third machine in the HA cluster.

In addition to the Active/Active Message Broker setup, the final configuration
allows the authors to simulate remote WebSphere Business Integration Adapters
that are under HA control. Figure 1-4 shows the distribution of resources in this
configuration.
