To my understanding, the Sequoia platform became mvEnterprise, which is still maintained though not energetically marketed by TigerLogic Corp (home of D3 and mvBase). Without the same hardware base as Sequoia, I don't know how resilient the platform is to hardware issues. I've never heard of an RS6000 being as fault-resistant as Sequoia, even with HA AIX. (Note term "fault-resistant" compared to "fault-tolerant".) As another Sequoia anecdote: An IT manager was surprised one day by a FedEx delivery of a motherboard. Apparently his system has lost a CPU and phoned to Support to get a new one, though no one at the company had noticed yet. The instructions were simply something like "Remove bad board, insert new board". Twenty years later people are still wondering if it's possible to minimize downtime... As to Baker's original request: >> We'd like to host our Business Layer on the MV system >> and serve It to our e-commerce portals, instead of >> re-coding our business rules first in Basic, then in >> .Net You may be interested in my recent blogs (link below) on creating Web Services for MV BASIC. With what I've built so far, no changes to the BASIC code are required and there is no need to know anything about XML or .NET or SOAP or WSDL or any of that other stuff. To the point above, I've already implemented the basics for failovers, where failure to invoke a subroutine on any given server will cause a retry down a list of alternate servers - a notice will be sent to the IT admin but the client won't know anything has gone wrong. It's not tough code, it's just something that needs to be considered.
