Thanks,

Re: enabling core dump in HP-UX
Java process can generate very large core files.
Check that the default core file size has not been deliberatley set to 0 in the users $HOME/.profile or in the system wide /etc/profile, i.e look for :
# ulimit -c 0
Example default size setting on one of my systems :
/# ulimit -c

Re: enabling core dump in HP-UX
The ulimit parameter has not been set in the .profile
Hence by default will it not coredump
Do i need to set only the ulimit which will coredump next time onwards ?
Thanks,
Ganesh

Re: enabling core dump in HP-UX
Correct - it should coredump by default.
What does the command ulimit -c show ?
Core file creation is actioned based on the user limit setting of the -c option :
# ulimit -c
# ulimit -Hc (hard limit)
# ulimit -Sc (soft limit)
To set it unlimited then,
# ulimit -HSc unlimited
