Hi there.
Check the scripts in /sbin/rc2.d or /sbin/rc3.d
Look at these scripts. Setup your script the same way. Place it in /sbin/rc3.d and it should work.

Hi,

The /sbin/rc script *expects* you to use the start/stop arguments. Have you any more details/reasons for this request?

Rgds, Robin.

Just make your script, as if it is a normal startup/shutdown script. The start and stop parameters will be ignored if you don't use them.

If those parameters are in the way, make a small start/stop script in /sbin/init.d that sources or executes your script without parameters if it is started with the "start" parameter.

Hi,

The stub procedure goes like this:

=============================
#!/sbin/sh

case $1 in
start) # enter startup command here ;;
stop) # enter shutdown command here, optional ;;
start_msg) # enter startup message here, optional ;;
stop_msg) # enter shutdown message here, optional ;;
esac
=============================

Hope this helps. Regards.

Create a dummy script in the /sbin/init.d that has the standard 'start/stop' options, which then calls the relevant script with the appropriate options.

eg. sap_ctrl script (for starting sap) calls the 'start_sap' command as p01adm in the 'start' conditional.

The script does have to work within the guidelines and standards set by HP-UX.

Share and Enjoy! Ian

Hi,
Usualy to start process on boot :
Create your script on /sbin/init.d
Create a link from this scrip to /sbin/rcx.d (where x indicate the start level) called SXXXyourscript.

Hi
If you just want to run a script at startup and shutdown you can place your script in /sbin/init.d, create soft links in /sbin/rc3.d for startup and soft link in /sbin/rc2.d for shutdown and the configuration file, if your want to run it occasionally in /etc/rc.config.d
Let it do what you want to do ignoring the start and stop argument. But I think you need to handle the startmsg and stopmsg arguments.

Hi,

As others say, the appropriate method for starting processes at boot time is the RC scripts. As long as your script's name begins with a capital S the script will be executed by /sbin/rc when it executes scripts for that run level. You don't have to use the case statement with start, stop, etc but it is highly recommended.

As an alternative, you could use /etc/inittab. This is not the generally accepted method and I suggest you avoid it. Mess up inittab and you've got trouble.

My advice is to stick with the RC scripts. It is the standard, there are templates (just use any system supplied rc script as a guide), and logging is provided (/etc/rc.log).
