Recovering from Server Node Software Corruption or Host Failure

Problem: The installed software on a node becomes corrupted or the host computer fails..

Recovery required:

  1. Ensure Unwired Server services on the data tier node are running. In versions of Unwired Platform 2.1 ESD #2 and earlier, the runtime services must also be running on a primary cluster node.
  2. If you are recovering a software component with the installer:
    1. Uninstall the affected component.
    2. Reinstall the affected component.
    3. If the component is a data tier component, copy the database file from the recovery server.
  3. If you are recovering a software component with a clone or snapshot image, revert to the most recent backup.
    Note: If reverting to a backup fails, or if Unwired Server services do not start after being restored, or if a backup is unavailable, you must reinstall the required components on the failed node.
