WebSphere Adapter module applications can be cloned as members of a cluster under certain conditions.
Clusters are used to provide scalability and availability to your applications in a network deployment environment.
WebSphere Adapter module applications that have either inbound or bidirectional traffic, cannot be cloned as members of a cluster. An application with purely outbound traffic can be cloned as a member of a cluster.
An application that has an inbound or bidirectional WebSphere Adapter (that is, including EIS exports) can still be given availability in a network deployment by use of an external Operating System High Availability (HA) management software package, such as HACMP, Veritas, or Microsoft Cluster Server.
