Upgrading a Simple Cluster

A simple cluster consists of one data tier node and one or more Unwired Server nodes, with failover capability between multiple Unwired Server nodes.

1. Shut down the nodes in this order:
   1. Secondary Unwired Servers – shut down services in this order:
      1. Sybase Unwired Server
      2. Sybase Control Center
      3. Sybase Unwired SampleDB (not applicable to Enterprise Server Edition)
   2. Primary Unwired Server – shut down services in this order:
      1. Sybase Unwired Server
      2. Sybase Control Center
      3. Sybase Unwired SampleDB (not applicable to Enterprise Server Edition)
   3. Data tier server – shut down these services, in any order:
      • Sybase Unwired CacheDB
      • Sybase Unwired ClusterDB
      • Sybase Unwired LogDataDB
      • Advantage Database Server®
2. Install the upgrade on each node in the cluster, in this sequence:
   1. Data tier node
   2. Primary Unwired Server
   3. Secondary Unwired Servers

   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.
