memory dump

[karthik_in83]

what is cross dump and core dump?what are the main advantages?

[karthik_in83]

can anyone tell me the path of cross dump and core dump?

[Dennis Handly]

Are you talking about a kernel panic dump, or an application core file?

I'm not sure I know what you mean by "cross dump"?

I hope u didnt see the question properly He is asking about Memory Dump

[Srimalik]

A core dump is a file which contains the state of a process(memory/registers/threads/stack) when the core was created.

The core file is present in the present working directory of the process which has generated the core.

If not produced intentionally, a core dump points to a possibility of a bug in the program ( may be a illegal memory access, an unexpected SIGNAL by someone etc)

I have never heard about a cross dump please tell me from where did you get this term. Any specific OS/ scenario/ context?

>Antony: I hope u didnt see the question properly

(I'm not sure why anyone would string those words together and use the word "hope"?)

I asked because I wanted to make sure. Srikrishan also thought it may have been about an application core dump.

Then those are two things I mentioned.

>I heard the crash dump it will keep all the process information, when the system crashes.

While it has that info, typically a crash dump is used to debug when the kernel panics/crashes.

A core file typically has all of the process information, when the process aborts.
