Advisors Cluster Information

Every system on which you install a module in the Advisors suite, where the module uses an Advisors Platform database, is a node in a cluster.

• A module is an application in the Advisors suite that you can install separate from other applications. For example, a WA Server or Contact Center Advisor XML Generator is a module.
• A node in a cluster is an entity that has an IP address. An example is a physical computer, or a virtual machine on a VM host.
• A node in a cluster is also referred to as a member of the cluster.

Members of the cluster communicate to share data that is cached in memory, and to transmit messages to perform workflows that require more than one module.

Even if you install Advisors on only one system, that system is a node in a cluster containing that one system.

A system that is a node in a cluster can run one Advisors module, or more than one Advisors module.

For example, the WA Server and WA Web Services are two modules, and you can install both on the same node. Alternatively, you can install the WA server on one cluster member, and WA web services on another cluster member.

Another example: WA Server and CCAdv XML Generator are two modules, and you can install them both on the same node or on different nodes. In the first case, you would have one cluster member, and in the second case, you would have two.
