Patching 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 the same services in the same order as for Secondary Unwired Servers.
   3. Data tier server – shut down these services, in any order:
      1. Sybase Unwired CacheDB
      2. Sybase Unwired Cluster DB
      3. Sybase Unwired LogDataDB
2. Install the patch on each node in the cluster, in this sequence:
   • Data tier node
   • Primary Unwired Server
   • Secondary Unwired Servers

   Note: Do not begin patching any secondary servers until the primary server has completely restarted all its services after being patched.
   1. Extract the patch archive file to a temporary location, for example, C:\tmp\2.1.3p2.
   2. Log in with administrator privileges, then open a Windows Command Prompt (cmd.exe) and change to the folder where you extracted the patch files.
      On Windows 7 and Windows Server 2008R2, start the Command Prompt with the Run as Administrator option.
   3. Run installebf.bat.
      • If the script detects environment issues, you see an error message and the patch process stops. Follow the instructions provided and restart the patch. If you cannot correct the issue, contact Sybase Technical Support.
      • If the patch script stops with an unexpected error message, look for locked files in the installation directory tree. Unlock any locked files and re-run the patch script.
        Note: The script cannot specifically detect locked files in the installation directory tree. The error message that appears when the script encounters locked files is unpredictable.
   4. Press Y, then Enter to install the patch.
   5. When the patch finishes, review the text on your screen for error messages.
      On successful completion of the patch, the services for the patched server are started, even if you have specified to manually start services.

      Note: After patching the data tier, the first Unwired Server may take as long as an hour to restart.
   6. Before proceeding, verify that the patched server is started.
