WebSphere Application Server Clustering
Overview
IBM WebSphere Application Server can be clustered by using the administrative
console or by scripting with the wsadmin tool. The starting point for this configuration
is a WebSphere Application Server that has been configured by the SAS
Deployment Wizard. The wizard configures WebSphere Application Server to
provide the resources needed by the SAS Web applications such as mail, JDBC,
and JMS. The wizard can also deploy the SAS Web applications to a server
instance. The following list identifies the high-level steps for deploying the SAS Web
applications on a WebSphere Application Server cluster:
1 Review the limitations in “SAS Middle-Tier Limitations” on page 2 and perform
the pre-configuration tasks in “Common Pre-Configuration Tasks” on page 5.
2 Create a server template from the application server that was configured by the
wizard.
3 Create a cluster and populate it with servers created with the server template.
4 Configure JVM options for the clustered servers and the stand-alone server.
5 Deploy the SAS Web applications to the cluster.
