Upgrading a Microsoft Cluster with Shared Hosts

A Microsoft cluster with shared hosts consists of two Unwired Servers colocated with two data tier servers, with failover capability between data tiers managed by Microsoft Cluster Service, also called Failover Clustering.

1. Shut down the nodes in this order:
   1. Secondary Unwired Servers – shut down these services in this order:
      1. Sybase Unwired Server
      2. Sybase Control Center
   2. Primary Unwired Server – shut down these services in this order:
      1. Sybase Unwired Server
      2. Sybase Control Center
2. On the active node, launch the MS Cluster Administrator and make sure the following active Unwired Platform resources are online:
   • Advantage Database Server service
   • Afaria Database Service (available with Unwired Platform version 1.5.2 or earlier)
   • Sybase Unwired CacheDB
   • Sybase Unwired ClusterDB service (available with Unwired Platform version 2.0 or later new installations)
   • Sybase Unwired LogDataDB service (available with Unwired Platform version 2.0 or later new installations)
3. Install the upgrade on the passive node, with all Unwired Platform resources online on the active node.
   Both data tier and Unwired Server are upgraded on the passive node.

   Note: Do not begin upgrading any secondary servers until the primary server has completely restarted all its services after being upgraded.
   1. Extract the patch archive file to a temporary location.
   2. Logging in with administrator privileges, open a Windows Command Prompt (cmd.exe) and change to the folder where you extracted the upgrade files.
   3. Run installebf.bat.

      The script runs an initial validation check on the files extracted from the upgrade package. If files are corrupted, delete the corrupted archive and download another copy of the upgrade package.

      If the script detects environment issues, you see an error message and the upgrade process stops. Follow the instructions provided and restart the upgrade. If you cannot correct the issue, contact Sybase Technical Support.

      The script does not detect locked files in the installation directory tree. The error message that appears when the script encounters locked files varies.

      If the installer stops with an unexpected error message, look for locked files in the installation directory tree. Unlock any locked files you find and re-run the upgrade script.

   4. Press Y, then Enter to install the upgrade.
   5. When the upgrade finishes, review the text on your screen for error messages.
      On successful completion of the upgrade, the services for the upgraded server are started, even if you have specified that services for the server are to be manually started.

      Note: After upgrading the data tier, the first Unwired Server may take as long as an hour to restart.
   6. Before proceeding, verify that the upgraded server is started.
4. Validate the upgrade on this passive node by starting the Unwired Platform services.
5. For the data tier server, make the passive node active.
   1. Launch Microsoft Cluster Administrator.
   2. Fail over the active node to the passive node.
   The node that was passive is now active.
6. Install the data tier upgrade on the new passive node.
   Both the data tier and Unwired Server are upgraded.
   1. Extract the patch archive file to a temporary location.
   2. Logging in with administrator privileges, open a Windows Command Prompt (cmd.exe) and change to the folder where you extracted the upgrade files.
   3. Run installebf.bat.
