Question No. 3

The core dump configuration for your system is:

A user is running a process in the global zone and the process crashes. The process information is:

User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash

The server host name is: zeus

What will the per-process core file be named?

Acore.bash.2663.global

Bcore.bash.2663.zeus

C/var/core/core.bash.2663

D/var/core/core.bash.2663.global

Show Answer

Correct Answer: C

Note the first line:

global core file pattern: /globalcore/core.%f.%p

The program name is bash

The runtime process ID is 2663

Note: By default, the global core dump is disabled. You need to use thecoreadmcommand with the-e globaloption to enable it. The-goption causes the command to append the program name(%f)and the runtime process ID(%p)to the core file name.
