Maintenance and Troubleshooting
Reviewing Cluster and Package States with the cmviewcl Command
Chapter 374
• Up. The package control script is active.
• Down. The package control script is not active.
• Unknown.
The state of the package can be one of the following:
• Starting. The start instructions in the control script are being run.
• Running. Services are active and being monitored.
• Halting. The halt instructions in the control script are being run.
Package Switching Attributes
Packages also have the following switching attributes:
• Package Switching. Enabled means that the package can switch to
another node in the event of failure.
• Switching Enabled for a Node. Enabled means that the package
can switch to the referenced node. Disabled means that the package
cannot switch to the specified node until the node is enabled for the
package using the cmmodpkg command.
Every package is marked Enabled or Disabled for each node that is
either a primary or adoptive node for the package.
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
