1.3.4 Replicating Server Groups
Server groups are unique to Oracle and are key to the scalability features of Oracle. A group contains one or more servers on a single node. System administrators can scale an Oracle application by replicating server groups and configuring load balancing within a domain.
Replicating a server group involves defining another server group with the same type of servers and resource managers to provide parallel access to a shared resource (such as a database). CORBA applications, for example, can use factory-based routing to split processing across the database partitions.
The UBBCONFIG
file specifies how server groups are
configured and where they run. By using multiple server groups,
Oracle can:
- Spread the processing load for a given application or set of applications across additional machines.
- For CORBA applications, use factory-based routing to send one set of requests on a given interface to one group, and another set of requests on the same interface to another group.
To configure replicated server groups, see Configuring Replicated Server Processes and Groups.
