Using Serviceguard Extension for RAC, 9th Edition, September 2010

For multi-node packages, node switching Disabled means the package cannot start on that
node.
Status of Group Membership
The state of the cluster for Oracle RAC is one of the following:
• Up. Services are active and being monitored. The membership appears in the output of
cmviewcl -l group.
• Down. The cluster is halted and GMS services have been stopped. The membership does not
appear in the output of the cmviewcl -l group.
The following is an example of the group membership output shown in the cmviewcl command:
# cmviewcl -l group
GROUP MEMBER PID MEMBER_NODE
DGop 1 10394 comanche
0 10499 chinook
DBOP 1 10501 comanche
0 10396 chinook
DAALL_DB 0 10396 comanche
1 10501 chinook
IGOPALL 2 10423 comanche
1 10528 chinook
where the cmviewcl output values are:
• GROUP—the name of a configured group.
• MEMBER—the ID number of a member of a group.
• PID—the Process ID of the group member.
• MEMBER_NODE—the Node on which the group member is running.
Service Status
Services have only status, as follows:
• Up—the service is being monitored.
• Down—the service is not running. It may have halted or failed.
• Uninitialized—the service is included in the package configuration, but it was not started
with a run command in the control script.
• Unknown.
Network Status
The network interfaces have only status, as follows:
• Up.
• Down.
• Unknown—whether the interface is up or down cannot be determined. This can happen
when the cluster is down. A standby interface has this status.
NOTE: Serial Line Status has been de-supported as of Serviceguard A.11.18.
Failover and Failback Policies
Packages can be configured with one of two values for the FAILOVER_POLICY parameter:
• CONFIGURED_NODE—the package fails over to the next node in the node list in the package
configuration file.
• MIN_PACKAGE_NODE—the package fails over to the node in the cluster with the fewest
running packages on it.
