Hi,

Thanks for you reply..

I am using AIX

Add it to the run level scripts under /etc/rc.d/. A run level script allow you to start and stop an application while changing the run level (which occurs when booting.) Put your run level script in the subdirectory of /etc/rc.d that is specific to the run level at which you wish your application to start. Scripts beginning with K are stop scripts, while scripts beginning with S are start scripts. Look at existing start scripts to see how to write your own start script correctly.

Thanks for your reply fpmurphy......

You mean that if you created the file like Start.ksh and store it in the /etc/rc.d it will call automatically when server starts up not inserver stop.

And if you create the file like KStop.ksh and store it in same path, it will call automatically when the server stop not in server start up...

Is my understanding is correct??????

Yes, that is the general idea.

In AIX there is a file /etc/inittab, which is first utilized, then,for each runlevel, there is a directory in /etc/rc.d which contains start/stop-scripts. You could add such a start/stop-script as fpmurphy suggested (this is the BSD way to do it), you could add a line to /etc/inittab (the SysV way to do it) or you could start it as a subsystem vie the System Resource Controller, which is a AIX speciality. Each possibility would lead to the script being executed on different points in time and different circumstances - every startup, every time a certain runlevel is entered, etc., etc.. All this doesn't even take into account that your system might be part of a high-availability cluster, where even more possiblities would arise because it could be started every time a certain cluster event triggers: the machine becomes promoted to the "working" part of the cluster, the machine becomes the non-working part as another machine takes over, etc., etc..

Out of curiosity: why didn't you ask this question in my living room, the AIX forum?

I hope this helps.
