Installing the Version 4.4.2 Update

  1. Make sure you have one of the prerequisites.
  2. Schedule downtime. The following table provides estimated installation times and server downtimes for this service pack. If you install the service pack on a Vocera clustered environment, downtime will be minimal (only seconds per failover) if you follow the installation instructions.

    Note: When upgrading from pre-4.4 releases to 4.4.0 or greater, a prompt trimming process will run to optimize the recorded name prompts. In a cluster upgrade, this process can run up to three times and could add unexpected delays to the upgrade process. For more information please contact technical support prior to planning the upgrade to versions of Vocera Voice software 4.4 and above.

  5. Install this service pack on any computer that runs the Vocera Voice Server, Vocera Telephony Server, Vocera SIP Telephony Gateway Vocera Badge Configuration Utilities, or Vocera Client Gateway. Update your Vocera Voice Server first.
    • If you are upgrading a cluster, run the installer on each standby node, fail over, and then run the installer on the remaining node.

  6. After you install the service pack, verify that the Vocera version number has been updated to version "4.4.2". You can verify that the Vocera version number has been updated in the following places:

    • The title bar of the Vocera Control Panel window.
    • The bottom right of the Administration Console or User Console.
  7. If you have deployed VAI applications, copy the server.jar file from the \vocera\server\lib directory on the Vocera Voice Server into your application's \lib folder. Generally, you should not need to revise or rebuild your application unless it uses methods that have changed in the latest version of server.jar.
