We have a user where a process is behaving abnormally and crashing. It would be great if a core file was generated, but I don't see one.
There is no core file being created in the /opt/core directory. Now, I have asked the user to submit the output of errpt -a and to check for errors with the following: LABEL: CORE_DUMP_FAILED.
There were none, unfortunately.
The user does not have root access to the AIX box, which means they cannot modify the location where core files are being generated, which I don't think would matter.
My question is whether having root access could be responsible for the core files not being generated or could it be some other cause?

Hi,
Currently, we have a Perl script from a third-party vendor that is generating core dumps. It has been reported. We can't turn off the script as it does generate some diagnostic file that's required. So at the moment, we have to let it continue to do its run.
I wish I can say the vendor is... (8 Replies)

gcore
gcore(1) User Commands gcore(1)NAME
gcore - get core images of running processes
SYNOPSIS
gcore [-pgF] [-o filename] [-c content] process-id...
DESCRIPTION
The gcore utility creates a core image of each specified process. By default, the name of the core image file for the process whose process
ID is process-id will be core.process-id.
OPTIONS
The following options are supported:
-c content Produces core image files with the specified content. The content description uses the same tokens as in coreadm(1M). The
-c option does not apply to cores produced due to the -p or -g flags.
-F Force. Grabs the target process even if another process has control.
-g Produces core image files in the global core file repository with the global content as configured by coreadm(1M). The com-
mand will fail if the user does not have permissions to the global core file repository.
-o filename Substitutes filename in place of core as the first part of the name of the core image files. filename can contain the same
tokens to be expanded as the paths in coreadm(1M).
-p Produces a core image file in the process-specific location with the process-specific content for each process as config-
ured by coreadm(1M). The command will fail if the user does not have permissions to the per-process core file repository.
OPERANDS
The following operand is supported:
process-id process ID
EXIT STATUS
The following exit values are returned:
0 On success.
non-zero On failure, such as non-existent process ID.
FILES
core.process-id core images
