NAME

       utmpd - user accounting database daemon

SYNOPSIS

DESCRIPTION

       user  accounting database daemon, manages the user accounting database which is the database of currently logged-in users.  This was previ-
       ously maintained by and files on HP-UX.

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

       utmpd(1M) takes care of synchronizing the legacy file and its own in-memory database.  The synchronization is bi-directional from the data-
       base to the and from the file to 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
	      Perform graceful shutdown.

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

DIAGNOSTICS

       logs error messages to the system log using syslog(3C).

WARNINGS

       If  is  shutdown  using synchronization between file and the file does not take place.  should not be shutdown by the user unless it is for
       debugging purpose.  On restart, utmpd(1M) rebuilds its database from the file.
