You've already received a lot of advice, most of it good. 

One important thing has not been pointed out by the other posters, though 
one of them alluded to it. That important fact is: RED HAT IS NO LONGER
SUPPORTING RH9. As was pointed out elsewhere, others are still providing
security patches for it. However, this sounds like a "mission-critical"
function, do you want to entrust it to an obsolete/unsupported version
of the OS? I wouldn't!

As others suggested, you should find out what distributions/versions of
Linux are required for the app you want to run, and choose one from that
list that is most likely to receive ongoing support from its vendor.
Keep a spare machine (preferably identical to the production one) up to
date with all vendor-released patches/updates, and once you've proven that
each batch of updates causes no trouble, apply them to the production box.
