Starts Oracle Rdb security auditing for the database. The Start
    qualifier by itself starts both security alarms and security
    audit journal records. Also, you can supply the Type=Alarm
    qualifier or the Type=Audit qualifier to start security alarms
    only or security audit journaling only.

    When you specify the Start qualifier, auditing starts immediately
    for all audit event classes that are currently enabled. Any
    subsequent audit events of currently attached users are recorded
    in the security audit journal, or alarms are sent to security-
    enabled terminals, or both, depending on what you have specified
    for your database.
