Hello All:

I am just wondering how one can analyze a core dump from an application.
What are the general guidelines etc.

After upgrading ram to 16G from 8G and increasing 3 to 5 processors on a
N4000, Oracle 9i core dumps (11i machine). HW upgrade done on friday and
since than 5 core dumps have been accumulated.

file on one core shows SIGSERV and another SIGABRT.

Any hints or reference material I could read up on how to analyze core dumps
(possible stack trace calling the kills?).

Any help/suggestions appreciated.

You just load the core and the executable that produced it into
the debugger:

gdb /path/to/oracle core
(gdb) info thread
(gdb) info shared
(gdb) thread apply all where

However, this will likely not make much sense to you.
You'll need to get Oracle support/developers involved. And if you
do, they'll tell you what further commands to run to get the info
*they* need.

Cheers,
