KILL PID, intern should kill another PID.
Hi All,

In my project i have two process runs in the back end.
Once i start my project, and execute the command ps, i get below output:

PID TTY TIME CMD
9086 pts/1 0:00 ksh
9241 pts/1 0:02 java
9240 pts/1 0:00 shell_script_bg

java with 9241 PID is the main process which runs my whole application.
if i have to say in one word, java process has the whole control of my app.

shell_script_bg with 9241 PID is the shell script, which starts the java command.

If i kill the java PID with kill -9 9241 , which shuts my complete application. But if i kill shell_script_bg pid, it not making my application go down.

My requirement is if i kill one PID it should intern kill java PID as well.
what r the changes i need to make in my shell script or any where else.

This is an urgent requirement. plz help me.

Regards,
Ravi.

kill.d

kill.d(1m)							   USER COMMANDS							kill.d(1m)

NAME

       kill.d - snoop process signals as they occur. Uses DTrace.

SYNOPSIS

       kill.d

DESCRIPTION

       kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
       ber and result.

       This program can be used to determine which process is sending signals to which other process.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       Default output, print process signals as they are sent.
	      # kill.d

FIELDS

       FROM   source PID

       COMMAND
	      source command name

       TO     destination PID

       SIG    destination signal ("9" for a kill -9)

       RESULT result of signal (-1 is for failure)

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       kill.d will run forever until Ctrl-C is hit.
