Unregistering a cluster of WebSphere-based servers

With the node removed from the IBM® Sametime® server cluster, you can now unregister the cluster from any node in the cluster. After you unregister the cluster, it can no longer be administered from the Sametime System Console, which also serves as the deployment manager.

Before you begin

Before you start this task, verify that you have removed all nodes from the cluster.

About this task

Removing a cluster involves running a utility that removes the cluster from the Sametime System Console. You only need to run this utility once, and you can run it from any node in the cluster.

Procedure

  1. On any node in the cluster, update the console.properties file on the deployment manager:
    1. Navigate to the InstallLocation/console directory to update the file.

      ./STSCServerCell/console/console.properties

      Attention: If you are uninstalling a Gateway server cluster, note that the Gateway cluster's Primary Node is installed on the same computer, so be sure to use the deployment manager profile.
    2. Open the console.properties file for editing.
    3. Fill in values for the following settings:
      Table 1. console.properties settings
      Property Value
      SSCHostName Type the fully qualified host name of the Sametime System Console server.
      SSCHTTPPort Type the HTTP port used for the Sametime System Console server if SSL is not enabled and the value for SSCSSLEnabled is "false."

      To determine the correct HTTP port, open the AboutThisProfile.txt file for the Sametime System Console Application Server Profile and use the setting specified for the "HTTP transport port." The default profile name is STSCAppProfile.
      SSCUserName Type the IBM WebSphere® Application Server User ID that you created when you installed Sametime System Console. The default is wasadmin.
      SSCPassword Type the IBM WebSphere Application Server password associated with the SSCUserName.
    4. Save and close the file.
  2. Open a command window and run the following command:
    • IBM AIX®, or Linux™
      removeWASClusterRegistration.sh
      Note: The script, removeWASClusterRegistration.sh, is located in ibm\WebSphere\STSCServerCell\console
    • Microsoft™ Windows™
      removeWASClusterRegistration.bat
  3. When prompted by the utility, enter the name of the cluster you are deleting, and press Enter.

Results

This utility deletes the cluster and generates a log file called ConsoleUtility.log, which it stores in the console/log directory.
