Please tell me some methods to analyse the cause of core dump in AIX.

From past experience IBM is pretty tight lipped about telling you how to analyse a core dump. You will have to open a PMR if you want details.

One thing you can do is to look in your errpt -a output. It usually tells you the name of the program or routines that were running when the core dump occurred. These may or may not have been the cause of the core dump though.

Good luck.

Hello,

From the IBM Cert Study Guide.

9.3.5 Analyzing system dumps
The kdb command allows you to examine a system dump or a running kernel.
The kdb command interprets and formats control structures in the system and
provides miscellaneous functions for examining a dump.

For example, to invoke the kdb command using a dump file named
/var/adm/ras/vmcore.0 and the kernel file named /unix, type:

1. kdb /var/adm/ras/vmcore.0 /unix

Regards, Leo.

kdb is used to review OS dumps, i.e. system crash or forced dump. 

dbx, idebug or gdb can be used to review an application core files.

-> find out which signal caused the core dump: file core_file

-> find out where the program was executing when the coredump occured (program's call stack):
dbx object_file core_file
where

dbx comes with bos.adt.debug and offers many more subcommands -> man dbx
