There are many different types of dumps. There are
memory dumps, process dumps, system state dumps, etc.
A "dump" is nothing more than taking the contents of
memory, or a process, or the state of the system and
putting them into a file. This is done so that an
analyst can try to figure out what went wrong. For
instance, multiple memory dumps can show changes to
the data in memory through a period of time. By
examining these changes, one can see exactly what went
on, as opposed to what was supposed to go on.
Oracle databases produce other types of dumps as well.
These dump files are placed into directories specified
by the USER_DUMP_DEST, BACKGROUND_DUMP_DEST, and
CORE_DUMP_DEST parameters. If a user process has a
certain type of error, it may force a dump into the
USER_DUMP_DEST directory.
