Parameter type	String
Syntax	CLUSTER_INTERCONNECTS = ifn [: ifn ... ]
Default value	There is no default value.
Parameter class	Static

CLUSTER_INTERCONNECTS provides Oracle with information about additional cluster interconnects available for use in Oracle9i Real Application Clusters environments.

The CLUSTER_INTERCONNECTS parameter can be used to override the default interconnect with a preferred cluster traffic network. This parameter is useful in Data Warehouse systems that have reduced availibility requirements and high interconnect bandwidth demands. You can also use CLUSTER_INTERCONNECTS to override the default interconnect chosen by Oracle.

For example, if you are running two instances of Oracle for two databases on the same machine, then you can load balance the interconnect traffic to different physical interconnects. This does not reduce Oracle availability.
