I believe someone has done this within Oracle, ie to read the datafile and dump into a flat-file, which you can then SQL*load. Don't know what the current status is.

As for OS format converter, I thought its more than just an endian issue - with high-order/low-order bits to represent file/block and porting groups free to shift the bits as they see fit?
