How to Create the RAC Framework Resource Group by Using the scrgadm Utility

Steps

1. On one node of the cluster, become superuser.

2. Create a scalable resource group.

   # scrgadm -a -g resource-group \   -y nodelist=nodelist \   -y maximum_primaries=num-in-list \   -y desired_primaries=num-in-list \   -y RG_mode=Scalable

   -g resource-group

   Specifies the name that you are assigning to the resource group.

   -y nodelist=nodelist

   Specifies a comma-separated list of cluster nodes on which Sun Cluster Support for Oracle Real Application Clusters is to be enabled. The Sun Cluster Support for Oracle Real Application Clusters software packages must be installed on each node in this list.

   -y maximum_primaries=num-in-list

   Specifies the number of nodes on which Sun Cluster Support for Oracle Real Application Clusters is to be enabled. This number must equal the number of nodes in nodelist.

     ---

     Note –

     If you are using the Sun StorEdge QFS shared file system, an additional resource is required to represent the metadata server for the Sun StorEdge QFS shared file system. This resource is not contained in the RAC framework resource group. For information about this resource, see SPARC: Resources for the Sun StorEdge QFS Shared File System.

     ---

8. Bring online the RAC framework resource group and its resources.

   # scswitch -Z -g resource-group

   -g resource-group

   Specifies that the resource group that you created in Step 2 is to be moved to the MANAGED state and brought online

How to Remove the RAC Framework Resource Group by Using the scrgadm Utility

The resources that the RAC framework resource group contains are described in Overview of the RAC Framework Resource Group. If the RAC framework resource group is created by using the scsetup utility, scsetup assigns names to the resources as listed in Names Assigned to RAC Framework Resources by scsetup.

Steps

1. On one node of the cluster, become superuser.

2. Remove all RAC server resource groups in the cluster.

   These resource groups were created as explained in How to Register and Configure Oracle RAC Server Resources.

   Remove each RAC server resource group as follows:

   1. Disable each RAC server resource in the resource group.

      For each resource, type the following command:

      # scswitch -n -j resource

      -j resource

      Specifies the resource that you are disabling

   2. Remove each RAC server resource in the resource group.

      For each resource, type the following command:

      # scrgadm -r -j resource

      -j resource

      Specifies the resource that you are removing

   3. Remove the RAC server resource group.

      # scrgadm -r -g rac-server-rg

      -g rac-server-rg

      Specifies the resource group that you are removing

3. Disable each resource that the RAC framework resource group contains.

   Disable the instance of the SUNW.rac_framework resource only after you have disabled all other resources that the RAC framework resource group contains. The other resources in the RAC framework resource group depend on SUNW.rac_framework.

   # scswitch -n -j resource

   -j resource

   Specifies the name of the resource that you are disabling. If this resource was created by using the scsetup utility, the name depends on the resource type, as shown in Names Assigned to RAC Framework Resources by scsetup.

4. Remove each resource that you disabled in Step 3.

   Remove the instance of the SUNW.rac_framework resource only after you have removed all other resources that the RAC framework resource group contains. The other resources in the RAC framework resource group depend on SUNW.rac_framework.

   # scrgadm -r -j resource

   -j resource

   Specifies the name of the resource that you are removing. If this resource was created by using the scsetup utility, the name depends on the resource type, as shown in Names Assigned to RAC Framework Resources by scsetup.

5. Unregister the resource type of each resource that you removed in Step 4.

   # scrgadm -r -t resource-type

   -t resource-type

   Specifies the name of the resource type that you are unregistering. This resource type was registered for the RAC framework resource group when the resource group was created. The resources that the RAC framework resource group contains are described in Overview of the RAC Framework Resource Group.

6. Remove the RAC framework resource group.

   # scrgadm -r -g resource-group

   -g resource-group

   Specifies the name of the RAC framework resource group that you are removing. If this resource group was created by using the scsetup utility, the name of the resource group is rac-framework-rg.

   ---

   Note –

   After you have removed the RAC framework resource group, you must boot each cluster node in noncluster mode and uninstall the Sun Cluster Support for Oracle Real Application Clusters software packages. For more information, see How to Remove Sun Cluster Support for Oracle Real Application Clusters From a Cluster.

Example B–1 Removing the RAC Framework Resource Group by Using the scrgadm Utility

# scswitch -n -j RAC1-rs
# scrgadm -r -j RAC1-rs
# scrgadm -r -g RAC1-rg
# scswitch -n -j RAC2-rs
# scrgadm -r -j RAC2-rs
# scrgadm -r -g RAC2-rg
# scswitch -n -j rac_svm
# scswitch -n -j rac_udlm
# scswitch -n -j rac_framework
# scrgadm -r -j rac_svm
# scrgadm -r -j rac_udlm
# scrgadm -r -j rac_framework
# scrgadm -r -t SUNW.rac_svm
# scrgadm -r -t SUNW.rac_udlm
# scrgadm -r -t SUNW.rac_framework
# scrgadm -r -g rac-framework-rg

This example shows the commands that are required to remove a RAC framework resource group that was created by using the scsetup utility. The resource groups RAC1-rg and RAC2-rg are RAC server resource groups that were created as shown in Example 3–3. The cluster from which this resource group is removed uses the Solaris Volume Manager for Sun Cluster.
