Sun Cluster Data Service for Oracle RAC Guide for Solaris OS

ProcedureHow to Preserve a Nondefault Value of the reservation_timeout Extension Property

The reservation_timeout extension property specifies the timeout value in seconds for the reservation step of a reconfiguration of Sun Cluster Support for Oracle RAC.

In Sun Cluster release 3.1, reservation_timeout was an extension property of the following resource types:

As of Sun Cluster release 3.2, reservation_timeout is an extension property only of the SUNW.rac_framework resource type. This property is removed from the SUNW.rac_cvm resource type and the SUNW.rac_svm resource type. The SUNW.rac_hwraid resource type is removed as of Sun Cluster release 3.2.

A nondefault value of the reservation_timeout extension property might be set for an existing resource of type SUNW.rac_hwraid, SUNW.rac_cvm, or SUNW.rac_svm. If you require this value after you upgrade to Sun Cluster release 3.2 11/09, perform this task to preserve the value.

  1. Before you migrate or remove the resource for which the reservation_timeout extension property is set, obtain the value of this property.


    # clresource show -p reservation_timeout -t resource-type
    resource-type

    Specifies the resource type of the resource for which the reservation_timeout extension property is set, namely, SUNW.rac_cvm, SUNW.rac_hwraid, or SUNW.rac_svm.

  2. When you migrate the existing instance of the SUNW.rac_framework resource type, set the reservation_timeout extension property to the value that you obtained in Step 1.


    # clresource set -p type_version=version \
-p reservation_timeout=timeout rac-framework-rs
    version

    Specifies the value of the type_version property for the version of SUNW.rac_framework to which you are migrating the instance. In Sun Cluster release 3.2 11/09, version is 5.

    timeout

    Specifies the value to which you are setting the reservation_timeout extension property. This value is the value that you obtained in Step 1.

    rac-framework-rs

    Specifies the name of the resource of type SUNW.rac_framework on your cluster. If the scsetup utility of Sun Cluster release 3.1 was used to create the RAC framework resource group, this resource is named rac_framework.

Example 7–2 Preserving a Nondefault Value of the reservation_timeout Extension Property

This example shows the commands for preserving a nondefault value of the reservation_timeout extension property that was set for a resource of type SUNW.rac_svm.

Before the migration of the resource of type SUNW.rac_svm, the following command is run to obtain the value of the reservation_timeout extension property:


# clresource show -p reservation_timeout -t SUNW.rac_svm

=== Resources ===                              

Resource:                                       rac-svm-rs

  --- Standard and extension properties ---    

  Reservation_timeout:                          350
    Class:                                         extension
    Description:                                   Timeout (in seconds) for the 
reservation step of Sun Cluster framework for RAC
    Per-node:                                      False
    Type:                                          int

During the migration of the resource of type SUNW.rac_framework, the following command is run to set properties as follows:


# clresource set -p type_version=4 \
-p reservation_timeout=350 rac_framework
