Sun Cluster Data Service for Oracle Guide for Solaris OS

Registering and Configuring Sun Cluster HA for Oracle

Tools for Registering and Configuring Sun Cluster HA for Oracle

Sun Cluster provides the following tools for registering and configuring Sun Cluster HA for Oracle:

The clsetup utility and Sun Cluster Manager each provide a wizard for configuring Sun Cluster HA for Oracle. The wizards reduce the possibility for configuration errors that might result from command syntax errors or omissions. These wizards also ensure that all required resources are created and that all required dependencies between resources are set.

Setting Sun Cluster HA for Oracle Extension Properties

Use the extension properties in Sun Cluster HA for Oracle Extension Properties to create your resources. To set an extension property of a resource, include the option -p property=value in the clresource(1CL) command that creates or modifies the resource. Use the procedure in Chapter 2, Administering Data Service Resources, in Sun Cluster Data Services Planning and Administration Guide for Solaris OS to configure the extension properties if you have already created your resources. You can update some extension properties dynamically. You can update others, however, only when you create or disable a resource. The Tunable entries indicate when you can update each property. See Appendix B, Standard Properties, in Sun Cluster Data Services Planning and Administration Guide for Solaris OS for details about all Sun Cluster properties.

SUNW.oracle_server Extension Properties describes the extension properties that you can set for the Oracle server. For the Oracle server, you are required to set only the following extension properties:

ProcedureHow to Register and Configure Sun Cluster HA for Oracle by Using the clsetup Utility

This procedure provides the long forms of the Sun Cluster maintenance commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS

ProcedureHow to Register and Configure Sun Cluster HA for Oracle by Using Sun Cluster Maintenance commands

This procedure provides the long forms of the Sun Cluster maintenance commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS

Before You Begin

Ensure that the following prerequisites are met:

Ensure that you have the following information:

  1. On a cluster member, become superuser or assume a role that provides solaris.cluster.modify and solaris.cluster.admin RBAC authorizations.

  2. Register the resource types for the data service.

    For Sun Cluster HA for Oracle, you register two resource types, SUNW.oracle_server and SUNW.oracle_listener, as follows.


    # clresourcetype register SUNW.oracle_server
# clresourcetype register SUNW.oracle_listener

  3. Create a failover resource group to hold the network and application resources.

    This step is not required if you use the Solaris ZFS, because the resource group was created when the highly available local ZFS was configured. The resources that are created in other steps in this procedure are to be added to this resource group.

    You can optionally select the set of nodes or zones on which the data service can run with the -n option, as follows.


    # clresourcegroup create [-n node-zone-list] resource-group
    -n node-zone-list

    Specifies a comma-separated, ordered list of zones that can master this resource group. The format of each entry in the list is node:zone. In this format, node specifies the name or ID of a node and zone specifies the name of a non-global Solaris zone. To specify the global zone, or to specify a node without non-global zones, specify only node.

    The order in this list determines the order in which the nodes or zones are considered primary during failover. This list is optional. If you omit this list, the global zone of each cluster node can master the resource group.

    resource-group

    Specifies the name of the resource group. This name can be your choice but must be unique for resource groups within the cluster.

  4. Verify that all of the network resources that you use have been added to your name service database.

    You should have performed this verification during the Sun Cluster installation.

    Note –

    Ensure that all of the network resources are present in the server's and client's /etc/inet/hosts file to avoid any failures because of name service lookup.

  5. Add a logical hostname resource to the failover resource group.


    # clreslogicalhostname create -g resource-group [-h logicalhostname] logicalhotname-rs
    logicalhostname

    Specifies a logical hostname. This logical hostname must present in your name service database. If logicalhostname and logicalhostname-rs are identical, logicalhostname is optional.

    logicalhostname-rs

    Specifies the name that you are assigning to the logical hostname resource that you are creating.

  6. Register the SUNW.HAStoragePlus resource type with the cluster.


    # clresourcetype register SUNW.HAStoragePlus

  7. Add a resource of type SUNW.HAStoragePlus to the failover resource group.

    Caution – Caution –

    Raw devices from Sun Cluster device groups are not supported in non-global zones.

    Note –

    The SUNW.HAStoragePlus resource type must be version 4 if it is to be supported in non-global zones.

    Note –

    If you use the Solaris ZFS for Oracle files, omit this step. The SUNW.HAStoragePlus resource was created when the highly available local ZFS was configured. For more information, see How to Prepare the Nodes.


    # clresource create -g resource-group -t SUNW.HAStoragePlus \
-p GlobalDevicePaths=device-path \
-p FilesystemMountPoints=mount-point-list \
-p AffinityOn=TRUE hastp-rs

    You must set either the GlobalDevicePaths extension property or the FilesystemMountPoints extension property:

    • If your database is on a raw device, set the GlobalDevicePaths extension property to the global device path.

    • If your database is on the cluster file system, specify mount points of the cluster file system and the local file system.

    Note –

    AffinityOn must be set to TRUE and the local file system must reside on global disk groups to be failover.

    The resource is created in the enabled state.

  8. Bring online the failover resource group in a managed state on a cluster node or zone.


    # clresourcegroup online -M resource-group
    -M

    Places the resource group that is brought online in a managed state.

  9. Create Oracle application resources in the failover resource group.

    • Oracle server resource:


      # clresource create  -g resourcegroup \
-t SUNW.oracle_server \ 
-p Connect_string=user/passwd \
-p ORACLE_SID=instance \
-p ORACLE_HOME=Oracle-home \
-p Alert_log_file=path-to-log \
-p Restart_type=entity-to-restart \
[-p Dataguard_role=role] \
[-p Standby_mode=mode] \-p resource_dependencies=storageplus-resource \
 resource

    • Oracle listener resource:


      # clresource create -g resource-group \
-t SUNW.oracle_listener \ 
-p LISTENER_NAME=listener \
-p ORACLE_HOME=Oracle-home \
-p resource_dependencies=storageplus-resource resource
    -g resource-group

    Specifies the name of the resource group into which the resources are to be placed.

    -t SUNW.oracle_server/listener

    Specifies the type of the resource to add.

    -p Alert_log_file=path-to-log

    Sets the path under $ORACLE_HOME for the server message log.

    -p Connect_string=user/passwd

    Specifies the user and password that the fault monitor uses to connect to the database. These settings must agree with the permissions that you set up in How to Set Up Oracle Database Permissions. If you use Solaris authorization, type a slash (/) instead of the user name and password.

    -p ORACLE_SID=instance

    Sets the Oracle system identifier.

    -p LISTENER_NAME=listener

    Sets the name of the Oracle listener instance. This name must match the corresponding entry in listener.ora.

    -p ORACLE_HOME=Oracle-home

    Sets the path to the Oracle home directory.

    -p Restart_type=entity-to-restart

    Specifies the entity that the server fault monitor restarts when the response to a fault is restart. Set entity-to-restart as follows:

    • To specify that only this resource is restarted, set entity-to-restart to RESOURCE_RESTART. By default, only this resource is restarted.

    • To specify that all resources in the resource group that contains this resource are restarted, set entity-to-restart to RESOURCE_GROUP_RESTART.

      If you set entity-to-restart to RESOURCE_GROUP_RESTART, all other resources (such as Apache or DNS) in the resource group are restarted, even if they are not faulty. Therefore, include in the resource group only the resources that you require to be restarted when the Oracle server resource is restarted.

    -p Dataguard_role=role

    Specifies the role of the database instance. Change role as follows:

    • To create a resource for a primary database instance that does not have standby instances configured, change role to NONE. This value is the default value.

    • To create a resource for a primary database instance that has standby database instances configured, change role to PRIMARY.

    • To create a resource for a standby database instance, change role to STANDBY.

    -p Standby_mode=mode

    Specifies the mode for the standby database instance. If you change Dataguard_role to NONE or PRIMARY, the value of the Standby_mode is ignored.

    • To specify a logical standby database, change mode to LOGICAL. This value is the default value.

    • To specify a physical standby database, change mode to PHYSICAL.

    resource

    Specifies the name of the resource that you are creating.

    Note –

    Optionally, you can set additional extension properties that belong to the Oracle data service to override their default values. See Setting Sun Cluster HA for Oracle Extension Properties for a list of extension properties.

    The resources are created in the enabled state.
