I'm planning to compress the Oracle export dump files of all Oracle database servers to reduce space usage on their disks.

My question is: Do you know of any good compression utility for compressing this type of file?

Oracle dumps files use a proprietary binary format. So you want a standard compression that is good for binary data. bzip2 is good with binary data, so I would recommend that.

HERE is a great article I used when making a backup script on some linux machines. Worked really well. I ended up using rzip for my needs. I used it to backup and compress all types of data files including SQL database dumps.

I'd first try using 7zip with ultra compression level and see what you can get. I definitely get better results from .7z than the .zip format...

bzip2 tends to be my default answer to such a task.
