o To use the RMU Set Audit command for a database, you must have the RMU$SECURITY privilege in the root file ACL for the database or the OpenVMS SECURITY or BYPASS privilege. o Audit journal records collected on a database can be stored only in the database from which they were collected. The database name specified with the RMU Load command with the Audit qualifier identifies to Oracle Rdb both the audit records to be loaded and the database into which they are to be loaded. o There is very little overhead associated with security auditing; no extra disk I/O is involved. Therefore, you need not be concerned about the impact to database performance should you decide to enable security auditing. o You can use the Daccess=object-type option to enable DACCESS checking for specific objects, but the general DACCESS class is not enabled until you explicitly enable it by using the Enable=Daccess qualifier with the RMU Set Audit command. Also, you need to use the Start qualifier with the RMU Set Audit command to start the auditing and alarms that have been enabled. o Alarms are useful for real-time tracking of auditing information. At the moment an alarm occurs, text messages regarding the alarm are displayed on security-enabled terminals. To enable a terminal to receive Oracle Rdb security alarms, enter the DCL REPLY/ENABLE=SECURITY command. You must have both the OpenVMS SECURITY and OpenVMS OPER privileges to use the REPLY/ENABLE=SECURITY command. o Audit records are useful for periodic reviews of security events. Audit records are stored in a security audit journal file, and can be reviewed after they have been loaded into a database table with the RMU Load command with the Audit qualifier. Use the DCL SHOW AUDIT/JOURNAL command to determine the security audit journal file being used by your database. o The AUDIT class is always enabled for both alarms and audit records, but does produce any alarms or audit records until auditing is started. The AUDIT class cannot be disabled. o When you specify the Daccess=object-type option and one or more other options in an options list, the Privileges=(privilege-list) qualifier must begin after the closing parenthesis for the options list. o To display the results of an RMU Set Audit command, enter the RMU Show Audit command. o You can use the Disable and Enable qualifiers with indirect file references. See the Indirect-Command-Files help entry for more information. o When the RMU Set Audit command is issued for a closed database, the command executes without other users being able to attach to the database.
