The FATMEN servers are started automatically at boot-time. This is done by adding the following line to the file /etc/inittab.
fatmen:2:wait:/etc/rc.fatmen > /dev/console 2>&1 # Start Fatmen
The file rc.fatmen is show below:
rc.fatmen
#!/bin/sh # # Start FATMEN servers # # if [ -x /u/jamie/bin/fatstart ] then echo Start FATMEN servers ... su - jamie /u/jamie/bin/fatstart 2>&1 fi
Normally, no other operation is required. Should it be necessary to stop the servers, the following script may be used:
fatstop
#!/bin/ksh # # Stop all FATMEN servers that are running and create a # file 'restart_fat' in the CWD that can be used to restart them. # stop=" " run=" " nolog=" " noscr=" " b="." d=`date` # # Ensure that variables are defined... # if [ -f restart_fat ] echo Remove old restart_fat file... then rm -i restart_fat fi for i in /fatmen/fm* do typeset -u fatgrp typeset -l fatman fatpath=$i fatgrp=`basename $i` fatman=$fatgrp eval $fatgrp=$fatpath;export $fatgrp # # and stop those servers that are running... # if [ -x $i/fatserv ] then # # does a log file exist? # if [ -f /fatmen/$fatgrp.log ] then echo Log file exists for $fatgrp - looking for existing process log=$log$b$fatgrp pid=`cat /fatmen/$fatgrp.log | awk 'printf "%s n",$13'` if (test $pid) then echo Looking for server process for $fatgrp if(ps -ae | grep -s $pid ) then echo FATSRV running PID = $pid run=$run$b$fatgrp echo rm /fatmen/$fatman/todo/signal.stop >> restart_fat echo Server stopped at $d > /fatmen/$fatman/todo/signal.stop else echo No existing server found for $fatgrp echo Removing old log file... rm /fatmen/$fatgrp.log if [ -f $i/todo/signal.stop ] then echo signal.stop file found! rm $i/todo/signal.stop echo '(removed)' fi fi fi fi fi done echo echo Log files found for $log | tr '.' ' ' echo Servers already running for $run | tr '.' ' ' echo fatstart >> restart_fat if [ -f restart_fat_fat ] then chmod +x restart_fat_fat echo restart reservers by typing restart_fat fi
Should a server abend, it can be restarted (after curing the problem) by rerunning the fatstart script that is invoked at boottime.
