Std question I always have for DB's on OpenVMS when comparing to Rdb - does
the DB support active-active clustering?

May of the popular DB's today like MySQL (if memory serves correctly) do not
support active-active .. only the traditional active-passive mode.

Also, Rdb supports row level locking which is a pretty big performance
feature that some DB's do not support.

Not sure if Mimer supports either of these features.
