How to force core dump of a process
We have an application that terminates with segmentation violation errors in the logs. No source code is available since this is a third party software that is way past its maintenance life cycle. Under these circumstances is there a way to force a core dump of the process for further analysis??
Please go easy on me, please... I'm a newbie...

Hi guys,
just want to know which core file pattern is best to set for core dumps:
1) per-process file name pattern
or
2) global file name pattern.
I will really appreciate an explanation why the chosen one is better.
Thanks a lot guys. (2 Replies)

PARTY(1) General Commands Manual PARTY(1)
NAME
party - set OS responses mode
SYNOPSIS
party ON|OFF|WHEREIS [ - ] dnv
DESCRIPTION
Operating systems being what they are, the admin people can easily grow tired of command responses that resemble dyslexic eugene-
speak filtered through Kernighan and Ritchie's collective back-brains. To alleviate this, we have included a slightly more
`casual' mode, in which the responses to all commands are first filtered through a customising routine (DUDE) , which makes them
sound a little more friendly while retaining their full information content (usually). The rooted(c) system prompt is changed to
`What now, dude?' and output from each command is terminated by `No problem, dude.'
OPTIONS
-v Verbose mode (ALL commands have a `verbose' mode). When this option is present, all filtered responses are preceeded by a
message: `This response has been parsed by the DUDE filter and is not intended to be some sort of sleazy come-on.'
-d Don't restart all processes after recompiling the /uselss/libs/eugene file (see below). This alows any important tasks to
complete beforehand.
-n Notify all users that they are about to be force-logged out and force-logged in again.
ON Activates the DUDE filter.
OFF De-activates the DUDE filter.
WHEREIS
Doesn't do anything, but we couldn't resist it.
EXAMPLES
%-) party on
What now, dude?
To compare the differing responses, here is output provided by the ispi -s command, with party OFF and party ON:
party OFF
line who why how long
==========================================================

party ON
Well, let's see who's on, eh? There's you, of course, on line 000 (Imagine that! Hahaha!) Oh look, on serIOus line 00F, it's that
cute little secretary - looks like she's lost her keyboard template again, she's been hitting the escape key for the past five minutes!
AND OF COURSE, the guys down in maintenance are playing `cosmic ballcrushers'. As usual. Well, who else, um, no-one really

maybe I should send some AMail to maintenance and get 'em to look at it? No problem, dude.
What now, dude?
FILES
/uselss/libs/bill&ted/DUDE
This is the pipe process, usually
started at system shoe, which lies
idle until party ON is issued.
/uselss/libs/eugene
Contains all of the ordinary, ho-hum
confusing computer - jargonese
responses which commands ordinarily
issue. Text file.
/uselss/libs/eugene.spoo
compiled version of the eugene file.
/ephemeral/eugene.chex
Checksum for the compiled eugene file.

crp(1), stuffio(2), doobrie(9), gouge(3), ftang(65534), wi(-1), edmond(29), jumpstart(2), vo_mit(992)
BUGS
The -n option can be slow.
If the n option is issued, some users in a wi editing session may not receive the `warning, restart imminent' message until after the
restart.
There is no way selectively to follow symbolic links.
