I think the 2 gig file limit is more a product of the OS, Unix can have this limitation unless you have large files enabled. This is how it works in my shop with HP/UX.

The only heads up I want to throw out there is that if you do choose to compress the .DMP file during export, you will need to know how to uncompress it during an import. If the uncompressed .DMP file is larger that 2 gigs uncompressed, you will not be able to open it via uncompress since your mount point will puke on you.

There is a way to read and use the compressed .DMP file without opening it but I am not sure how this works.
Anyone?
Do you just reverse the pipe?
