How to get the core dump to analyse the process which stopped on SOLARIS 10?

[dperez79]

Hi all,

i have a process under SUN SOLARIS 10 running with 5 threads.
One of them dies with a high data level processing, but it doesn't generate a core dump.
How can I get this core dump to analize the process??

Thanks.. Daniel P.

Re: SOLARIS 10 thread

Core dumb will be generated when your process does some blunder(Seg fault, devide by zero, etc) and terminated by OS.

I don't think for simple thread termination, the core will be generated.

Re: SOLARIS 10 thread

use truss comand (man truss)

The truss utility executes the specified command and produces a trace of the system calls it performs, the signals it receives, and the machine faults it incurs. Each line of the trace output reports either the fault or signal name or the system call name with its arguments and return value(s).

example

truss cat /etc/resolv.conf
