Not that long ago (well, maybe it was a while now that I think of it) I supported an IBM internal application that was written in REXX, accessed SQL/DS databases and ran on a VM machine. IIRC, they ran a seperate VM machine for each service center (it managed centers that custom configured PC/POS terminals for overnight delivery to customer locations) because they couldn't improve the memory handling and performance issues as the application scaled up.

IBM had to bring in an outside SQL/DS (IIRC) consultant to "fix" their database accesses/storage - in one week he made the application 300% faster (IIRC)...

I never picked up REXX, but I'm sure it's still running, esp. in odd OS/2 applications...
