- zzzcpan 9y agoHmm, two-phase commit Informix included in like late 90s, which is pretty much the only thing related to distributed systems it had. None of them were really distributed databases in any way of course. The closest thing to a distributed database you could have back then was NonStop SQL, but it was designed with an assumption of a fast reliable network or more like a supercomputer.
- DrScump 9y agoI guess I was imagining it when I used the features myself internally starting in 1989 or so. Distributed client/server was first implemented in Informix-SE in the late 1980s but was more widely used starting with Informix-OnLine. Version 5.0 (general release in late 1991) had two-phased commit, but I think 4.X did also no later than summer 1990 because I did some onsite diagnosis/fixing for a major client then. There are references to OnLine 5.0 features and general release in the Informix 1991 Annual Report[0].
