AIX is based on UNIX System V Release 2, (YES 2!) and has none, repeat none, of the "goodies" that System V Release 3 has, notably STREAMS and TLI, the combination of which is recognized as superior in the industry to sockets (see "The STREAMS Machine", Mini-Micro Systems, February 1989). I dont know what release of System V THW is familiar with, but the System V/386 versions now coming out are based on Release 3. It's unclear in what decade OSF/IBM will come out with a version of AIX that approaches the functionality available in UNIX System V Release 3. IBM is ludicrously far behind in UNIX System development. If not for IBM's divisive efforts to standardize the UNIX System around AIX, AIX would be dead today. That's not to say that AIX is not a serious competitor in the marketplace for those who don't mind running yesterday's technology gotten second-hand from a company whose profit margins are guaranteed by proprietary hardware and software (hats off to microchannel!).

On the contrary, it was IBM that missed the boat; they're now furiously trying to catch up. AT&T did not splinter the UNIX marketplace. People found UNIX so useful and portable that offshoots of the original UNIX System proliferated. Notably, XENIX, SUNOS, and BSD. AT&T, in UNIX System V Release 4.0, is offering BSD/SUNOS/XENIX compatibility as a major feature. Rather than being "arrogant and incompetent", AT&T is attempting to offer a single UNIX System platform that users of other variants can move towards to increase the portability and reusability of code, and achieve greater hardware (vendor) independence. IBM's AIX is a step back in time. > >I expect AIX to be a very good OS in the future. It looks like IBM is fixing >some of the big problems with Sys V UNIX like security and tape utilities. Tell me more. In light of your comment below, I don't think you know. However, "in the future" is an apt phrase. >Does anyone out there have any experience with AIX or Mach? Enquiring minds >want to know. > What are you basing your comments on if you don't have experience with AIX? I've seen it, and I'm unimpressed. Any of the System V/386 alternatives cited in previous postings (SCO pops to mind, as well as AT&T's own version) are superior to AIX. Adding to all this the new "goodies" that ATT is adding to UNIX System V in Release 4, I can't help but think that the IBM/OSF propaganda machine is succeeding in getting people to believe that they can somehow jump into UNIX System development and do it better than the people who have been doing it for years (I don't mean just AT&T). It seems like someone at Big Blue woke up a while back and said "Hey, we better get into this UNIX stuff!" It seems to me that all they really wanted to do was throw a great big monkey wrench at AT&T in the hopes that they could catch up in the interim.
