Perl is definitely not my strong side either - one more reason why I
abaondoned the LARRD perl-scripts.

I looked at the one remaining BB server I have, and it seems you're
right - LARRD really does sort the datasets alphabetically by name when
it sets up the vmstat RRD file. It seems it does this only for the
vmstat data.

If you do come up with a tool for this, I would appreciate it if I may
distribute it with Hobbit.

Dont forget that this is a regexp - I think you meant '/oracle/PRD/sapdata.*'  
with a dot before the asterisk.
