Distributed Materialization in a Clustered Environment
If you are using a clustered environment for report generation (as explained in Configuring Server Clustering), and you want to distribute your materialized views across multiple data nodes, use independent machines for each cluster node and each data node, as shown below.
Figure 37. Data Grid in a Clustered Environment

To configure a data grid in a clustered environment, follow the steps below:
1. Follow the instructions in Configuring Server Clustering to created a clustered reporting environment.
2. Follow the instructions in Report Server on Machine 1, Data Server on Machine 2, Data Nodes on Machines 3-N to create a data grid. However, note the following:
Do not install the Report Server as described in step 1. The machine which you have already configured in the reporting cluster as “Cluster Node 1” (containing the Administration Servlet) will act as the Report Server for the data grid.
Do not install the Data Server or Data Nodes on any machine which is already being used as a node in the reporting cluster.
3. Verify that the cluster proxy, cluster nodes, and Data Server are all utilizing the same SREE Home directory. This allows the cluster nodes and the Data Server to share the same materialized view and security settings, so that a materialized query created by a cluster node can be executed on the Data Server.
To create a materialized view in this data grid environment, you must log into Enterprise Manager on the Data Server machine. (You cannot create a materialized view by using Enterprise Manager on any other machine.) See Creating a Materialized View for further information.
