1.5 Creating Clusters and Cloning Application Servers

In an IBM WebSphere cell, you can create new Application Servers that inherit the attributes of an existing server by using one of the following processes: ■ Clone an existing standalone Application Server to create a second standalone Application Server, which inherits its attributes from the first server. In this case, you clone the Application Servers by using the Clone function on the Configure Application Servers screen. ■ Create a new cluster by using an existing Application Server as the first cluster member, and then add a new cluster member to the cluster. The new cluster member inherits the attributes of the first cluster member. In this case, you add the new cluster members by using the Add function on the Configure Additional Cluster Members screen. The new cluster member is a clone of the first cluster member. When you create a standalone Application Server that is a clone of an existing Application Server, all applications and libraries that are targeted to the source server are also deployed to the clone. In addition, any of the following services that are targeted to the source server are automatically targeted to the clone: ■ connectionFactory ■ queueConnectionFactory ■ topicConnection ■ Queue ■ Topic ■ activationSpec ■ Data source ■ URLProvider ■ workManager ■ busMember ■ customService ■ resourceAdapter When you create a cluster, all applications and libraries that are targeted to the first cluster member are automatically moved from that server to the cluster. In addition, any of the following services that are targeted to the first cluster member are moved from the server to the cluster: ■ connectionFactory ■ queueConnectionFactory ■ topicConnection ■ Queue ■ Topic ■ activationSpec ■ Data source ■ URLProvider Configuration Overview 1-9 ■ workManager ■ busMember However, when you create a cluster, the following services are not moved from the first cluster member to the cluster. These services cannot be targeted to clusters, and can be targeted only to individual servers: ■ customService ■ resourceAdapter 1-10 Configuration Guide for IBM WebSphere Application Server 2 Using the Configuration Wizard 2-1 2 Using the Configuration Wizard This chapter describes how to use the Oracle Fusion Middleware Configuration Wizard to create and update cells.
