For what we are talking about here (VMS as back-end for IoT
generated data/transaction) RMS might not be an issue. Oracle
Rdb doesn't use RMS for it's general DB I/O. Only for specific
operations such as database backup, table load/unload, database
export/import and similar. Not for anything done during regular
operations.

Sometimes back in the early 90's someone on INFO-VAX wrote:

I do not now how other DB's such as MariaDB runs its DB I/O...

So, for what we are talkning about here, RMS might be a non-issue.
