Hi,

Is binary core file generated automatically or it can be generated by executing a command also ?

Thanks,
Shiv

A core file is generated when programs dumps/aborts. It also depends on how a program is coded. You can make a certain program to dump core by sending signal 3.

kill -3 "pid_of_program"

Hi Shiv,

Either way it is possible. An application may crash at any time due incorrect coding, etc.. Also, you can create a core of running process by # kill -3

This should give you more information,

Hi Shiv ,

core files generated automatically , whenever an application or process terminates abnormally.

You can check the detials of core file with # strings core | more

And investigate and can delete them to recover free space.

When we use $kill -3 pid of java process it gives java core dump and not binary core dump. I believe binary core dump and java core dump are 2 different things.

Please correct me if i have misunderstood this.

I think you are talking about java debug files and unix core files. Unix core files are binary files. To create java debug files, there must be a seperate procedure. java debug file and unix core dump are two different things.

Hi Shiv,

Are you talking about core created by java VM or a java application created any core ?
