That's a very good question.

In the context given, it's almost impossible to answer.

Judging from the group of 'dba' on the file, my **GUESS** is that it is a database dump file potentially generated by the Oracle 'exp' command.

I think the better person to ask would be the user anzpradm since that is the user that generated the file.

If it is an Oracle 'exp' (export), it can only be "read" by the Oracle 'imp' (import) command.

You could try running the command:

# file /tmp/dump/Live_20090708_21.dmp

and see if it tells you anything useful.

Because of the directory name it must be a dump of something. Extensions are meaningless in unix, so the use of "file" (see above) may be helpful.

Hi:

The 'file' command reads the first 512 bytes of a file in order to "guess" its classification (e.g. Ascii text, ELF-32 object, etc).

You might also try 'strings' to obtain some idea of the content.
