Background Updater and Vocera Clusters

After Vocera 4.4 (or a more recent version) has been installed on your Vocera Cluster, you can take advantage of the background update feature to ensure that users experience minimal downtime during subsequent updates to badge properties or firmware. During a background update the badge will always download firmware and settings from the active server.
  1. Update the badge.properties file in the \vocera\config directory on the active server. A minute or two later, the file will be synchronized with the standby server.
  2. Update the standby node(s):
    1. On the standby node, shut down the Vconfig by choosing Run > Exit.
    2. Update the standby node by installing the latest Vocera service pack.
    3. Reboot the standby node.
    4. Wait for the Vocera Voice Server on the standby node to rejoin the cluster and perform a remote restore.
      Important: After the Vocera Voice Server starts, it initially comes up as an active node, and then within a minute it rejoins the cluster and performs a remote restore. With a large database, a remote restore can take several minutes.
    5. On the active node, shut down the Vconfig by choosing Run > Exit.
      A standby node becomes active. Badges connect to it and download new firmware and settings in the background.
    6. Update the remaining Vocera Voice Server.
