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  individuā€
       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.
