> I guess 'important suppliers' is a relative term.  Digital's Rdb has had full
two phase commit and distributed databases since V4.0 (mid 1991).  We use it
and have no 'war' stories to speak of.  It just works.  We don't distribute
databases but have various nodes of a VAXCluster accessing the same database
requires some kind of distributed functionally and magically two phase commit
handles that.  We have demostrated distributed databases under Rdb V4.0a across
DECNET between two nodes not on the same cluster and amazing it just worked. 
Sometimes I wonder what all the uproar is about.  I also think too much is made
of the Oracle and Ingres transportability because I have had reports within our
company and have read of many projects in trade magazines that Oracle based
projects/applications are a bear to implement and many never get completed.  At
our site we are implementing our fourth major Rdb project within a 3 year
period with few problems.  Yet Oracle keeps winning the 'Database of the Year'
awards.  I have no direct experience with it but almost all of the much touted
V7.0 database features of Oracle have been in Rdb for the last two years and
work with no problem.  I wonder with Oracle's track record how long before the
CUSTOMERS will be able to produce a large (100+ tables,100+ programs) system
from V7.0 on any platform.

Pardon me while I don my asbestos suit..
