How to Register and Configure the Oracle ASM Resource Group (clsetup)

Note -  You can also use the Oracle Solaris Cluster Manager browser interface to perform this task, as well as optionally configuring resources for Oracle Clusterware and Oracle ASM. For Oracle Solaris Cluster Manager log-in instructions, see How to Access Oracle Solaris Cluster Manager in Administering an Oracle Solaris Cluster 4.4 Configuration. After you log in, click Tasks and then click Oracle Real Application Clusters to start the wizard.

When you register and configure the Oracle ASM resource group for a cluster, the Oracle ASM resource group is created.

Perform this procedure from one node only.

Note -  The clsetup utility currently allows ongoing administration of an Oracle RAC framework running only in the global cluster. For ongoing administration of a Support for Oracle RAC framework configured in a zone cluster, you need to instead use the Oracle Solaris Cluster maintenance commands.

Before You Begin

  • Ensure that Oracle ASM disk groups are configured. For more information, see Using Oracle ASM.

  • Any project you created to run Oracle ASM exists in the projects name service database for the user that runs that application. If no custom project is created for the application, the default project is used. For more information, see the projects(1) man page.

    Ensure that you have the following information:

  • The name of the Oracle Grid Infrastructure home directory.

  • The list of Oracle ASM systems identifiers (SID).

  • The names of the Oracle ASM disk groups to use.

Note -  If your Support for Oracle RAC configuration requires using Oracle ASM with Solaris Volume Manager mirrored logical volumes, you might experience either of the following conditions:

  • Performance degradation. See Article 603825.1 at My Oracle Support (https://support.oracle.com) for additional information.

  • Failures of the SUNW.ScalDeviceGroup probe. These failures result in a loss of availability of any service that is dependent on the SUNW.ScalDeviceGroup resource.

You can mitigate these issues by increasing the IOTimeout property setting for the SUNW.ScalDeviceGroup resource type.

# clresource set -p IOTimeout=timeout-value-in-seconds resource-name

The default for the IOTimeout property is 30 seconds but can be set much higher. Determine the optimal setting for each system individually, starting with a value of at least 240 seconds.

  1. Assume the root role on any cluster node.
  2. Start the clsetup utility, verify prerequisites, and navigate to the Support for Oracle RAC configuration section.
  3. Choose the Support for Oracle RAC location.

    Select the global cluster or a zone cluster. The clsetup utility displays a list of Support for Oracle RAC components to configure.

  4. Choose to configure Automatic Storage Management (ASM).

    The clsetup utility displays a list of the cluster nodes to select.

  5. Follow the prompts in the clsetup utility to provide the following information.
    Data to Provide
    Guidelines
    Your Values
    Cluster nodes on which to run Oracle ASM
    Ensure that the nodes are listed in the order in which the nodes are to appear in the Oracle RAC framework resource group's node list.
    To choose nodes, type a comma-separated or space-separated list of the option numbers for the nodes you choose.
    Oracle ASM instance resource to use
    If no Oracle ASM instance resource is available, the clsetup utility prompts you to create a resource.
    Oracle Grid Infrastructure home directory
    Provide the full path.
    Project where Oracle ASM is to run
    If you did not create a project where Oracle ASM will run, select the default project.
    Oracle ASM SIDs
    If the list of Oracle ASM system identifiers (SIDs) that are discovered in the cluster is not correct, you can change the SIDs.
    Oracle ASM disk-group resources
    Choose whether to create a disk-group resource or to use an existing disk-group resource.
    Oracle ASM storage resources to manage the file-system mount point for the Oracle Grid Infrastructure home directory
    If no storage resource exist, the clsetup utility creates one when you complete Oracle ASM configuration.
    Oracle ASM disk-group resources to manage Oracle ASM disk groups
    Choose whether to create a disk-group resource or to use an existing disk-group resource.
    Oracle ASM disk groups
  6. Confirm the object names.
    1. If you require a different name for any Oracle Solaris Cluster objects, choose the name to change and type the new name in response to the prompt.
    2. To confirm your selection of Oracle Solaris Cluster object names, type d.
  7. To create the configuration, type c.

    The clsetup utility displays a progress message to indicate that the utility is running commands to create the configuration. When configuration is complete, the clsetup utility displays the commands that the utility ran to create the configuration.

    When the configuration process completes, you can press Return repeatedly to exit from the clsetup utility. If you prefer, you can leave the clsetup utility running while you perform other required tasks before using the utility again.

Resource Configuration

The following table lists the default resource configuration that the clsetup utility creates when you complete this task.

Resource Name, Resource Type, and Resource Group
Dependencies
Description
Resource type: SUNW.scalable_rac_server_proxy
Resource name: rac_server_proxy-rs
Resource group: rac_server_proxy-rg
Strong dependency on the Support for Oracle RAC framework resource.
Offline-restart dependency on the clustered Oracle ASM disk-group resource.
Offline-restart dependency on the Oracle Grid Infrastructure framework resource.
When configured with Solaris Volume Manager for Sun Cluster, strong positive affinity by the Support for Oracle RAC instance proxy resource group for the Support for Oracle RAC framework resource group.
When configured with hardware RAID, strong positive affinity by the Support for Oracle RAC instance proxy resource group for the clustered Oracle ASM disk-group resource group.
