How to Upgrade Sun Cluster HA for WebSphere MQ Integrator

If you need to set a value for a parameter , you must remove and reregister the Sun Cluster HA for WebSphere MQ Integrator resource for which you are changing the parameter.

The parameters that are introduced in Sun Cluster 3.1 9/04 apply to the resources for all components, namely:

• Broker component

• User Name Server component

Perform this task for each WebSphere MQ Integrator resource that you are modifying.

Perform this task only if you are setting or modifying parameters that are introduced in Sun Cluster 3.1 9/04.

Steps

1. Save the resource definitions.

   # scrgadm -pvv -j resource > file1

2. Disable the resource.

   # scswitch -n -j resource

3. Remove the resource.

   # scrgadm -r -j resource

4. Configure and register the resource.

   1. Go to the directory that contains the configuration file and the registration file for the resource.

      # cd /opt/SUNWscmqi/prefixutil

   2. Edit the configuration file for the resource.

      vi prefix_config

   3. Run the registration file for the resource.

      # ./prefix_register

   prefix denotes the component to which the file applies, as follows:

   • sib denotes the Broker component.

   • siu denotes the User Name Server component.

5. Save the resource definitions.

   # scrgadm -pvv -j resource > file2

6. Compare the updated definitions to the definitions that you saved before you updated the resource.

   Comparing these definitions enables you to determine if any existing extension properties have changed, for example, time-out values.

   # diff file1 file2

7. Amend any resource properties that were reset.

   # scrgadm -c -j resource -x|y resource

8. Bring online the resource.

   # scswitch -e -j resource
