Hi,

Not sure if it is possible without killing the process.

# kill -6 PID
will produce a core file, but will also kil, the process.

Other suggestion is to use truss/tusc.

Not possible I think. What exactly you are trying to do? If you are looking at getting the run image of the processes, you can do that.

Hi,

Don't think it's possible.

Do a search for a utility called "gcore"; possibly on Google with +gcore +"HP-UX" as search targets. I figure you can search as easily as I now that you know "gcore". It's also possible to launch a process under the gdb debugger and dump a core.

Thank you, guys.

1. HP's gdb (/opt/langtools/bin/gdb) from version 3.2 onwards has a command 'dumpcore' to achieve this.

2. gcore

3. use comand "thread apply all bt"; this method just print call stack, sometimes it's enough
