Sun Cluster Data Service for Oracle Real Application Clusters Guide for Solaris OS

ProcedureHow to Remove Sun Cluster Support for Oracle Real Application Clusters From a Cluster

The cluster node from which you perform this task must be booted in cluster mode.

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. Remove the RAC framework resource group.


    Note –

    The following instructions explain how to perform this operation by using the scsetup utility. For information about how to perform this operation by using the scrgadm utility, see How to Remove the RAC Framework Resource Group by Using the scrgadm Utility.


    1. Start the scsetup utility.


      # scsetup
      

      The scsetup main menu is displayed.

    2. Type the number that corresponds to the option for data services.

      The Data Services menu is displayed.

    3. Type the number that corresponds to the option for configuring Sun Cluster Support for Oracle Real Application Clusters.

      The Sun Cluster Support for Oracle RAC menu is displayed.

    4. Type the number that corresponds to the option for removing the RAC framework resource group.

      The scsetup utility displays a list of the cluster nodes on which the RAC framework resource group exists. The scsetup utility also asks you to confirm that the RAC framework resource group should be removed from these nodes.

    5. To confirm that the scsetup utility should remove the RAC framework resource group from the listed nodes, type y.

      The scsetup utility removes the RAC framework resource group and the resources that this resource group contains from the listed nodes.

  4. Boot each node in the cluster in noncluster mode.

  5. From each node in the cluster, uninstall the Sun Cluster Support for Oracle Real Application Clusters software packages for the storage management scheme that you are using for the Oracle Real Application Clusters database.


    x86 only –

    If you are using the x86 platform, ignore references to the SUNWudlm package and the SUNWudlm package in the commands that follow.


    • If you are using Solaris Volume Manager for Sun Cluster, type the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr SUNWscmd
      
    • If you are using VxVM with the cluster feature, type the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr SUNWcvmr SUNWcvm
      
    • If you are using hardware RAID, Sun StorEdge QFS, Network Appliance NAS devices, or ASM without a volume manager, run the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr SUNWschwr
      

    Note –

    To prevent the userland cluster membership monitor (UCMM) daemon ucmmd from being started when the cluster is rebooted, you must uninstall the Sun Cluster Support for Oracle Real Application Clusters software packages.
