Using Serviceguard Extension for RAC, 6th Edition, April 2008

NODE_FAIL_FAST_ENABLED parameter is set to NO for the Oracle Clusterware package,
and is set to YES for the package monitoring CSS-HB subnet (Oracle Cluster Interconnect
Subnet Package as shown in the package configuration parameters examples below).
NOTE: Do not configure CLUSTER_INTERCONNECT_SUBNET in the RAC Instance
package due to the RAC-IC network being the same as CSS-HB network.
The following is an example of the relevant package configuration parameters:
Oracle Clusterware Package:PACKAGE_NAME CRS_PACKAGEPACKAGE_TYPE

Serviceguard cluster configuration parameters, see “Guidelines for Changing Cluster
Parameters” (page 53)
Alternate Configuration - Multiple RAC Databases
When there are multiple independent RAC databases on the same cluster and if there
is insufficient bandwidth over a single network, a separate network can be used for
different database interconnect traffic. This will avoid RAC-IC traffic of one database
from interfering with that of another.
