Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters Guide

Removing Sun Cluster Support for Oracle Parallel Server/Real Application Clusters

Removing Sun Cluster Support for Oracle Parallel Server/Real Application Clusters removes the RAC framework resource group or removes nodes from this resource group.

How to Remove Sun Cluster Support for Oracle Parallel Server/Real Application Clusters From a Cluster

The cluster node from which you run the scsetup utility or scrgadm utility to perform this task must be booted in cluster mode.

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

  2. 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 Parallel Server/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.

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

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

    • 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 support, type the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr SUNWschwr
      
    • If you are using the cluster file system, type the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr
      

    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 Parallel Server/Real Application Clusters software packages.


How to Remove Sun Cluster Support for Oracle Parallel Server/Real Application Clusters From Selected Nodes

  1. Become superuser.

  2. Boot in noncluster mode the nodes from which you are removing Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.

  3. Remove the nodes from 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 Nodes From the RAC Framework Resource Group by Using the scrgadm Utility.


    1. Start the scsetup utility.


      # scsetup
      
    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 Parallel Server/Real Application Clusters.

      The Sun Cluster Support for Oracle RAC menu is displayed.

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

      The scsetup utility responds as follows:

      • The list of nodes in the RAC framework resource group is displayed.

      • The scsetup utility prompts you for the list of nodes that you are removing.

    5. Type a comma-separated list of the nodes that you removing from the RAC framework resource group.

  4. (Optional) From each node that you removed, uninstall the Sun Cluster Support for Oracle Parallel Server/Real Application Clusters software packages for the storage management scheme that you are using.

    • 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 support, type the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr SUNWschwr
      
    • If you are using the cluster file system, type the following command:


      # pkgrm SUNWscucm SUNWudlm SUNWudlmr
