Using Serviceguard Extension for RAC, 4th Edition, February 2007

Serviceguard Configuration for Oracle 10g RAC
Interface Areas
Chapter 240
If CRS is not configured to start the listener automatically at Oracle
Cluster Software startup, the listener startup can be automated with
supported commands, such as srvctl and lsnrctl, through scripts or
SGeRAC packages. If the SGeRAC package is configured to start the
listener, the SGeRAC package would contain the virtual IP address
required by the listener.
Manual Startup and Shutdown
Manual listener startup and shutdown is supported through the
following commands: srvctl and lsnrctl
Network Monitoring
SGeRAC cluster provides network monitoring. For networks that are
redundant and monitored by Serviceguard cluster, Serviceguard cluster
provides local failover capability between local network interfaces (LAN)
that is transparent to applications utilizing User Datagram Protocol
(UDP) and Transport Control Protocol (TCP).
For virtual IP addresses (floating or package IP address) in
Serviceguard, Serviceguard also provides remote failover capability of
network connection endpoints between cluster nodes and transparent
local failover capability of network connection endpoints between
redundant local network interfaces.
NOTE Serviceguard can not be responsible for networks or connection
endpoints that it is not configured to monitor.
SGeRAC Heartbeat Network
Serviceguard supports multiple heartbeat networks, private or public.
Serviceguard heartbeat network can be configured as a single network
connection with redundant LAN or multiple connections with multiple
LANs (single or redundant).
CSS Heartbeat Network
The CSS IP addresses for peer communications are fixed IP addresses.
When CSS heartbeats are on a single network connection and does not
support multiple heartbeat networks. To protect against a network
