Use unattended start-up mode to allow access to the master keys when the password holders unavailable.
Generally, using unattended start-up mode requires that you:
Enable the automatic master key access configuration parameter.
(Optional) set the master key startup file path and name. Otherwise, Adaptive Server uses the default file path and name.
Add automatic_startup copies for the master keys or dual master keys for databases for which you intend to have unattended start-up.
