B. Preset Actions for DBMS Errors and Logged Alerts
The status of resource groups and resources for Support for Oracle RAC indicates the status of Oracle RAC in your cluster. Use Oracle Solaris Cluster maintenance commands to obtain this status information.
To obtain status information for resource groups, use the clresourcegroup(1CL) command.
To obtain status information for resources, use the clresource(1CL) command.
For example:
# clresourcegroup status +
# clresource status -g resource-group +
Specifies the resource group that contains the resources whose status information you are displaying.

For information about options that you can specify to filter the status information that is displayed, see the following man pages:
The following examples show the status of resource groups and resources for a configuration of Support for Oracle RAC on a four-node cluster. Each node is a machine that uses the SPARC processor.
The cluster in this example is running version 10g Release 2, 11g, or 12c of Oracle RAC. The configuration in this example uses a Sun QFS shared file system on Solaris Volume Manager for Sun Cluster to store Oracle files. The configuration includes a multiple-owner volume-manager framework resource group to contain the volume manager resource.
The resource groups and resources for this configuration are shown in the following table.

Example 6-1 Status of a Faulty Oracle RAC Framework Resource Group
This example provides the following status information for an Oracle RAC framework resource group that is faulty.
A reconfiguration error has prevented the rac_framework resource from starting on cluster node pclus1.
The effects of this reconfiguration error on resource groups and other resources are as follows:
The rac-framework-rg resource group is offline and in the start failed state on cluster node pclus1.
The rac_udlm resource, the rac_svm resource, and the crs_framework resource are offline on cluster node pclus1.
All other multi-master resource groups and the resources that the groups contain are offline on cluster node pclus1.
All failover resource groups have failed over from cluster node pclus1 to a secondary node.
All multi-master resource groups and the resources that the groups contain are online on the remaining nodes.
