Portal Server 7.2的集群支持增强了。

Cluster support for Portal Server 7.2With Portal Server 7.2, the steps to install portal on an AS cluster is straight forward. It is just like creating multiple portal instances the only difference being the instances belong to a cluster. The only additional attribute to be set for the cluster specific instance is the ClusterID attribute.

All it requires is to create an AS cluster with the required number of instances and create a portal instance for each of the clustered application server instances.

The cluster setup instructions page specifies how to create a simple cluster setup with 2 instances managed by a load balancer.

Adding a new instance to the cluster is also straightforward. Create an application server instance (e.g. newinstance) belonging to the cluster (e.g pscluster). Then create a portal instance pointing to the created appserver instance and the appserver cluster i.e, set WebContainerInstanceName=newinstance and ClusterID=pscluster in the WebContainer.properties.SJSAS91 file and run psadmin create-instance.
