SUNW.rac_framework

, rac_framework

- resource type implementation for the framework that enables Oracle Solaris Cluster Support for Oracle Real Application Clusters (Oracle RAC)

Description

The SUNW.rac_framework resource type represents the framework that enables Oracle Solaris Cluster Support for Oracle RAC. This resource type enables you to monitor the status of this framework.

The SUNW.rac_framework resource type is a single instance resource type. Only one resource of this type may be created in the cluster.

To register this resource type and create instances of this resource type, use one of the following means:

• Oracle Solaris Cluster Manager

• The clsetup(1CL) utility, specifying the option for configuring Oracle Solaris Cluster Support for Oracle Real Application Clusters

• The following sequence of Oracle Solaris Cluster maintenance commands:

  1. To register this resource type, use the clresourcetype(1CL) command.

  2. To create instances of this resource type, use the clresource(1CL) command.

When a resource of this type is brought offline on a node, the transition from the online state to the offline state requires a finite time to complete. During the transition to the offline state, the resource continues to participate in reconfiguration processes. However, when the resource is offline on a node, changes to resource properties are not effective on the node until the resource is brought back online. Oracle Solaris Cluster displays a warning message to this effect when a resource of this type is disabled.

The transition to the unmanaged state of a resource group that contains a resource of this type requires a finite time to complete. During the transition to the unmanaged state, the Oracle RAC framework continues to participate in framework reconfiguration processes. However, when the resource group is unmanaged, changes to resource properties are not effective on the node. To stop the Oracle RAC framework, the node must be rebooted.

The extension properties of the SUNW.rac_framework resource type are as follows:

reservation_timeout

Type integer; minimum 100; maximum 99999; defaults to 325. This property specifies the timeout (in seconds) for the reservation step of a reconfiguration of Oracle Solaris Cluster Support for Oracle RAC. You can modify this property at any time.

Examples

Example 1 Creating a rac_framework Resource

This example registers the SUNW.rac_framework resource type and creates an instance of the SUNW.rac_framework resource type named rac_framework-rs. The example assumes that a resource group named rac-framework-rg has been created.

phys-host-sc1# clresourcetype register SUNW.rac_framework
phys-host-sc1# clresource create -g rac-framework-rg \
-t SUNW.rac_framework rac_framework-rs 

Example 2 Changing a Property of a rac_framework Resource

This example sets the timeout for the reservation step of a reconfiguration of Oracle Solaris Cluster Support for Oracle RAC to 350 seconds. The example assumes that a resource of type SUNW.rac_framework that is named rac_framework-rs has been created.

phys-host-sc1# clresource set 
\-p reservation_timeout=350 rac_framework-rs
