On a Unix system it is advisable to start Web Crossing automatically when the server boots, and shut it down gracefully before the server shuts down. Rebooting the server before Web Crossing has closed all files and exited can corrupt the database.

To start Web Crossing, move to the Web Crossing binaries directory and execute webx-run with the arguments "-daemon -server":

cd /somedir/some_other_dir/mydir/webx/
./webx-run -daemon -server

To stop Web Crossing, read the webx.lock file in the Web Crossing binaries directory and kill that process ID. Do not ever use "kill -9" as that will corrupt the database. It's best to be sure Web Crossing has shut down gracefully before rebooting the server. Here's an example perl script that shuts down two Web Crossing processes:

#! /usr/bin/perl

#shutdnpf.pl

# a perl script to shut down the server gracefully, especially useful in the event of

# a power failure. Kills the main and secondary Web Crossing processes, waits for them to

# die before proceeding with shutdown.

print "Emergency shutdown in progress...\n";

print "Finding Web Crossing process ID's...\n";
if (open(PIDFILE, "/www/webx/main/webx/webx.lock")){
#get process ID
while(){
$MainPid = $_;
}
}
else{
$NoMainProcess = 1;
}
close PIDFILE;
if (open(PIDFILE, "/www/webx/secondary/webx/webx.lock")){
#get process ID
while(){
$SecondaryPid = $_;
}
}
else{
$NoIspProcess = 1;
}
close PIDFILE;
print "Sending kill command to Web Crossing processes..\n";
# kill the webx processes
if (!$NoMainProcess){
`kill $MainPid`;
}
if (!$NoSecondaryProcess){
`kill $SecondaryPid`;
}

#see if any webx process is running, loop until ps can't find it
$PsOut = `ps -aux | grep webx`;
while ($PsOut){
sleep 3;
print "Web Crossing processes still running...\n";
$PsOut = `ps -aux | grep webx`;
}
print "\nAll Web Crossing processes killed\n\n";
#endfile

su user -c /path/to/start-webx

where user is the username you want webx to run under. You will also need to make sure that all the files and directories in the webx
installation are owned by the user you wish to start webx under.
