 NAME    [Toc]    [Back]
      utmpd - user accounting database daemon

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/utmpd

 DESCRIPTION    [Toc]    [Back]
      utmpd, user accounting database daemon, manages the user accounting
      database which is the database of currently logged-in users.  This was
      previously maintained by /etc/utmp and /etc/utmpx files on HP-UX.

      Upon startup, utmpd writes its pid to the file
      /etc/useracct/utmpd_pid.  Applications can add, update, or query
      entries into the database using the getuts() APIs.  See the getuts(3C)
      manual page for more information.

      utmpd(1M) takes care of synchronizing the legacy /etc/utmpx file and
      its own in-memory database.  The synchronization is bi-directional
      from the utmpd's database to the /etc/utmpx and from the /etc/utmpx
      file to utmpd's database.  However, this synchronization does not
      happen in real time.  There is a time lag which could span from a few
      seconds on a lightly loaded system to a few minutes on a heavily
      loaded system.

    Signal Processing    [Toc]    [Back]
           SIGTERM        Perform graceful shutdown.

                          This causes the daemon to write its in-memory user
                          accounting database to the /etc/utmps file and
                          exit.

 DIAGNOSTICS    [Toc]    [Back]
      utmpd logs error messages to the system log using syslog(3C).

 WARNINGS    [Toc]    [Back]
      If utmpd is shutdown using SIGTERM, synchronization between /etc/utmpx
      file and the /etc/utmps file does not take place.  utmpd should not be
      shutdown by the user unless it is for debugging purpose.  On restart,
      utmpd(1M) rebuilds its database from the /etc/utmps file.
