How to Verify the Status of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters

1. Become superuser.

2. Type the following command:

   # scstat -g

The following example shows that status of a RAC framework resource group that is faulty.

Example 3–1 Status of a Faulty RAC Framework Resource Group

-- Resource Groups and Resources --

            Group Name        Resources
            ----------        ---------
 Resources: rac-framework-rg  rac_framework rac_udlm rac_cvm


-- Resource Groups --

            Group Name        Node Name  State
            ----------        ---------  -----
     Group: rac-framework-rg  node1      Online faulted
     Group: rac-framework-rg  node2      Online


-- Resources --

            Resource Name     Node Name  State     Status Message
            -------------     ---------  -----     --------------
  Resource: rac_framework     node1      Start failed Degraded - reconfiguration in progress
  Resource: rac_framework     node2      Online    Online

  Resource: rac_udlm          node1      Offline   Unknown - RAC framework is running
  Resource: rac_udlm          node2      Online    Online

  Resource: rac_cvm           node1      Offline   Unknown - RAC framework is running
  Resource: rac_cvm           node2      Online    Online

This example shows the status of the resources in a RAC framework resource group for the following two-node configuration of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters:

• The configuration contains a RAC framework resource group that is named rac-framework-rg.

• The rac-framework-rg resource group contains the following resources:

  • An instance of the SUNW.rac_framework resource type that is named rac_framework

  • An instance of the SUNW.rac_udlm resource type that is named rac_udlm

  • An instance of the SUNW.rac_cvm resource type that is named rac_cvm

This example provides the following status information:

• A configuration error has prevented the rac_framework resource on cluster node node1 from starting.

• The effects of this configuration error on other entities on cluster node node1 are as follows:

  • The rac-framework-rg resource group is online, but faulted.

  • The rac_udlm resource and the rac_cvm resource are offline.

• The rac-framework-rg resource group and all resources on cluster node node2 are online.

The following example shows that status of a RAC framework resource group that is operating correctly.

Example 3–2 Status of an Operational RAC Framework Resource Group

-- Resource Groups and Resources --

            Group Name        Resources
            ----------        ---------
 Resources: rac-framework-rg  rac_framework rac_udlm rac_cvm


-- Resource Groups --

            Group Name        Node Name  State
            ----------        ---------  -----
     Group: rac-framework-rg  node1      Online
     Group: rac-framework-rg  node2      Online


-- Resources --

            Resource Name     Node Name  State     Status Message
            -------------     ---------  -----     --------------
  Resource: rac_framework     node1      Online    Online
  Resource: rac_framework     node2      Online    Online

  Resource: rac_udlm          node1      Online    Online
  Resource: rac_udlm          node2      Online    Online

  Resource: rac_cvm           node1      Online    Online
  Resource: rac_cvm           node2      Online    Online

This example shows the status of the resources in a RAC framework resource group for the following two-node configuration of Sun Cluster Support for Oracle Parallel Server/Real Application Clusters:

• The configuration contains a RAC framework resource group that is named rac-framework-rg.

• The rac-framework-rg resource group contains the following resources:

  • An instance of the SUNW.rac_framework resource type that is named rac_framework

  • An instance of the SUNW.rac_udlm resource type that is named rac_udlm

  • An instance of the SUNW.rac_cvm resource type that is named rac_cvm

This example indicates that all resources and resource groups in this configuration are online.
