Library /sys$common/syshlp/sysgen.hlb WRITE, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On VAX systems, the implementation of security auditing within
    SYSGEN has altered the reporting of modifications to the system
    parameter file VAXVMSSYS.PAR. System managers can receive
    notification of a change to the file by setting up an access
    control list (ACL) on the file to signal such an event, as in the
    following example:

    $ SET SECURITY/ACL=(ALARM=SECURITY,ACCESS=WRITE+FAILURE+SUCCESS)-
    _$ SYS$SYSTEM:VAXVMSSYS.PAR

    For more information about setting ACLs, refer to the OpenVMS
    User's Manual and the OpenVMS Guide to System Security.

    On Alpha systems, both the WRITE ACTIVE and WRITE CURRENT
    commands send a message to OPCOM and log the event.
