Hi ,
Working on AIX 4.3. An internal error from my apps engine suddenly causes the engine to die. During this time i do notice a core file being dumped in the directory from where I try to re-start my engine.
Q is how does one read this core file, or I should say 'what is this core file'?
thnx (2 Replies)

Hi Guys,
I was wondering if somebody could give me a link to a very good source of information or document about core dump process and How to's about it. I have also googled it and found some articles myself.
Thanks

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)

core
CORE(5) BSD File Formats Manual CORE(5)NAME
core -- memory image file format
SYNOPSIS
#include <sys/param.h>
DESCRIPTION
A small number of signals which cause abnormal termination of a process also cause a record of the process's in-core state to be written to
disk for later examination by one of the available debuggers. (See sigaction(2).) This memory image is written to a file named by default
core.pid in the /cores directory; provided the terminated process had write permission in the directory, and the directory existed.
The maximum size of a core file is limited by setrlimit(2). Files which would be larger than the limit are not created.
The core file consists of the ~ Mach-O(5) header as described in the <mach-o/loader.h> file. The remainder of the core file consists of
various sections described in the Mach-O(5) header.
NOTE
Core dumps are disabled by default under Darwin/Mac OS X. To re-enable core dumps, a privlaged user must edit /etc/hostconfig to contain the
line:
COREDUMPS=-YES-
SEE ALSO gdb(1), setrlimit(2), sigaction(2), Mach-O(5), sysctl(8)HISTORY
A core file format appeared in Version 6 AT&T UNIX.
