something special with hp-ux startup script ?

[Pouponnot]

Hello,

I have a little problem but I can't find the solution (I don't know hp-ux very well)
In my mind, when you want start a software on unix system startup you must write a script in /etc/init.d (/sbin/init.d/bbclient under hp-ux) and create a link in /etc/rc3.d (/sbin/rc3.d/ under hp-ux).
so I have this :

# uname -a
HP-UX HP-NSR B.11.00 U 9000/879 288035332 unlimited-user license
# ls -la /sbin/init.d/bbclient
-rwxr-xr-x 1 root sys 885 Sep 13 14:47 /sbin/init.d/bbclient
# ls -la /sbin/rc3.d/S999bbclient
lrwxrwxrwx 1 root sys 21 Dec 28 2004 /sbin/rc3.d/S999bbclient -> sbin/init.d/bbclient

# cat /sbin/init.d/bbclient
#!/bin/sh
#
# Copyright (c) 1991-1999 by Sun Microsystems, Inc.

#ident "@(#)Arret demarrage du client bbuser 12/03/02 AvS"
id=`/bin/ps -edf | /bin/grep bbc |/bin/grep -v bbclient|/bin/grep -v grep| /bin/awk '{print $2}'`
case "$1" in
'start')
if [ -n "$id" ]; then
echo "big brother client is already started"
else
echo "starting big brother client"
(su - bbuser -c "/home/bbuser/bbc/runbb.sh $1&")>/dev/console 2>&1
fi
;;

'stop')
if [ -n "$id" ]; then
echo "Stopping big brother client"
(su - bbuser -c "/home/bbuser/bbc/runbb.sh $1&")>/dev/console 2>&1
else
echo "big brother client is not running"
fi
unset id
;;
*)
echo "Usage: $0 { start | stop }"
exit 1
;;
esac


When I do this, all is well, the softare run:
/sbin/init.d/bbclient start
but when I do a reboot, the software don't start.
It's a basic question but under solaris and linux there is no problem.
Is there something special for startup script under hp-ux ?

Thanks a lot for your help

what is there in /etc/rc.log regarding to your bbclient script. Is it your machine run level 3?

check /etc/inittab or who -r

I think your link should say

/sbin/rc3.d/S999bbclient -> /sbin/init.d/bbclient

Or was the missing leading "/" on bbclient a typo?

[VEL_1]

Create startup & kill files /sbin/rc3.d .

Eg:
To start the any script when reboot,

ln -s /sbin/init.d/call_script /sbin/rc3.d/S900call.rc

To kill the any script when reboot,

ln -s /sbin/init.d/call_script /sbin/rc3.d/K900call.rc

Note:
Here original file is /sbin/init.d/call_script

Julien,

Try creating S899bbclient instead of S999bbclient.

You can also create a run-level 4 for your HP-UX server.

Check with "who -r" and change your default run-level after a reboot to 4.

May be a problem with symbolic link ?

# ls -la /sbin/rc3.d/S999bbclient
lrwxrwxrwx 1 root sys 21 Dec 28 2004 /sbin/rc3.d/S999bbclient -> sbin/init.d/bbclient

Do this,
# rm -rf /sbin/rc3.d/S999bbclient
# cd /sbin/rc3.d/
# ln -s /sbin/init.d/bbclient S999bbclient

hth.

Hi Julien,

when customizing rc scripts on startup I always use /sbin/init.d/template. I should suggest you to start from the template and re-create your startup script based on that. Also it needs a configuration file under /etc/rc.config.d and I see that it's missing in your startup script.

A lot of docs about how to configure it into ITRC forum:

HTH.

Best regards,

Hello,

to get feedback at startup/shutdown, you have to implement the arguments
start_msg
stop_msg

for your rc-script like
...
;;
start_smg) echo big brother client ;;

Leave this message output in your
start)-block.

When a start/stop script doesn't seem to work, the first place to look is the start/stop log: /etc/rc.log where you'll see the start message (missing in your script) and any output from that script.

There are actually two files to create: the start/stop script and the configure script. The configure script is stored in /etc/rc.config.d and usually named the same as the start/stop script. In it's simplest form, the configure script might just say:

BBRUN=1

and then in your start/stop script, you would test for BBRUN=1 to start the program (never test for BBRUN=1 for stopping it since it may be running and if you change BBRUN=0 for the next reboot, it won't be stopped during shutdown.

The line:

id=`/bin/ps -edf | /bin/grep bbc |/bin/grep -v bbclient|/bin/grep -v grep| /bin/awk '{print $2}'`

might be somewhat protable between flaors of Unix but it is an awful way to find a process by name. It will return programs like bbc1 and userbbc and bbbccc. HP-UX has a very powerful ps command that eliminates grep completely and simplifies getting the details you want by using -o. Replace the id line above with:

id=$(UNIX95= ps -C bbc -o pid=)

This will have either an empty string (id="") if not bbc process is found, or a list of all the copies of bbc (b ut not bbcclient, etc).

I have attached a heavily documented template file you can use to build a good start/stop script.
