LAMCLEAN(1)                      LAM COMMANDS                      LAMCLEAN(1)




NAME

       lamclean - Attempt to clean entire LAM system.


SYNTAX

       lamclean [-hv]


OPTIONS

       -h      Print the command help menu.

       -v      Be verbose.


DESCRIPTION

       The lamclean command attempts to remove all user processes and messages
       from all nodes.  It also de-allocates all user allocated resources  and
       cancels  all user process registrations.  This happens by invoking many
       different remote services which have previously been invoked  individu-
       ally  by  several  other commands.  These commands should still be used
       when partial selective removal of user presence is desired.  Otherwise,
       lamclean  is  a  quick  and convenient way of starting over after a bad
       application run without rebooting the system.

       lamclean takes the following actions on the following system  processes
       on all nodes:


       kenyad         The  LAM  SIGUDIE signal (terminate) is sent to all user
                      processes.  See doom(1).

       bufferd        The entire daemon is reset to its  initial  state  after
                      booting.  See sweep(1).

       filed          All user file descriptors are closed.  See fctl(1).

       traced         All traces are removed.  See lamtrace(1).

       lamclean  will  not  succeed if any of the nodes are unreachable due to
       catastrophic failure or maximum buffer overflow with link jamming.   If
       lamclean  does not return, use lamwipe(1) and lamboot(1) to restart the
       multicomputer.
