Run a script using DBX
I have a script like this script = GF1_dd_Daemon_Sh PROCESS_NAME=RG INSTANCE=RG PART_ID=1
Inside this there is an executable which is called. When I run this script(#!/bin/ksh ) it creates a core dump and using dbx when i analyse the stack trace I cannot get any much info.
Is there any way to run the script using DBX and can trace the point where the executable is creating the core dump.
I am using SOLARIS.
Thanks.

One common approach is to add a variable to the script called something like $DEBUGGER
#!/bin/sh
echo "this is the script"
$DEBUGGER the_executable arg1 arg2
If you set the DEBUGGER environment variable to "dbx", then when you run the script, dbx will be started and it will give you a dbx prompt.
If you're using the Solaris Studio IDE, you can use "ss_attach" instead of "dbx" and it will attach the debugging session to an IDE that is already running.
Check the man page for ss_attach.
- Inside the script check what are the arguments that are being passed to the executable (binary).
- start the dbx with that executable
- after it start set the arguments which you have discovered in step 1
- stop in GMF_mdg_EXECmain
- then start checking the code flow
