And perhaps they really didn't know the arc volume until they tested. For a new load that may be something only determinable by testing. I've had the same situation. You find out by testing, then you either load in noarchivelog, switch to archivelog and backup, or get more disk, or just don't worry about it and delete them and take a baseline backup when done. Personally, I usually just do the noarchivelog route because it goes much faster, but the DBA may also have other legitimate issues, like measuring I/O saturation. Just like with a DW or any non-transaction based situation, if it takes longer to recover than just reload, recovery can be inappropriate. Which is a polite term for stupid.
