I am following the article
http://www.sun.com/bigadmin/content/submitted/per_process_path.jsp to enable the per-process core file on my Solaris 9 platform. But it seems not work for me. Here are the details:

Also I have a puzzle about the core file permission. The coreadm man page says:
When generated, a global core file will be created mode 600
and will be owned by the super-user. Non-privileged users
cannot examine such files.
Ordinary per-process core files are created mode 600 under
the credentials of the process. The owner of the process can
examine such files.
But the core generated by gcore has permission 644.
