You can cluster Data Relationship Management Web applications with either Oracle HTTP Server or third-party load balancers. For instructions on clustering with Oracle HTTP Server, see “Configuring Load Balancing for Data Relationship Management Web Applications” in the Oracle Hyperion Data Relationship Management Installation Guide.
Data Relationship Management Server applications can be clustered for load-balancing only, using a primary-secondary machine configuration. Long-running read-only operations can be processed on secondary application servers, to reduce the processing load on the primary application server that is handling write operations. For instructions on configuring Data Relationship Management Server applications for load-balancing, see “Configuring Host Machines” in the Oracle Hyperion Data Relationship Management Installation Guide.
Note: | The processing of requests by application servers may not be distributed evenly among the machines in the cluster. Routing to a specific machine is based on the data being accessed and the type of operation being performed. |
With Data Relationship Management installed in a clustered database environment, you can select Generate scripts to be run by a database administrator when creating a database from the Repository Wizard in the Data Relationship Management Configuration Console. Two scripts are generated: one for creating the schema owner, or database, and one for creating the database schema objects. For instructions on clustering the Data Relationship Management repository, see the documentation for the database software being used.
