Recovering from a lost appliance

In case you lose an appliance, you can use the backup of the config database to restore the appliance configuration onto a new machine. Simply go thru the install procedure and create an appliance with the same identity as the machine that was lost. This should yield an appliance with an empty config database; you can import the configuration into this empty database using

mysql -u userid -p password  archappl < /path/to/backupfile

Restarting the appliance after this should pick up the imported configuration. As the JVM can cache DNS lookups, giving your replacement appliance the same IP address as the one that was lost should also help if you have a cluster of machines.
