Our section here at JPL have finally decided that VMS on VAXes are not the
way God planned it, and are in the middle of evaluating UNIX for our newly
purchased VAX 8600. Would anbybody with experiences on a VAX running UNIX
please take the time to respond to this short list of questions?
Our 8600 will be used as a development machine, with lots of C users, maybe
some database applications, and heavy networking. Currently, the rest of
our LAN consists of Suns, Masscomps, Vaxes, and IBM/ATs, all running TCP/IP.
So far, the systems in the running are:
1) BSD 4.3 (system license + source from Berkeley)
2) System 5
3) Ultrix
4) more/BSD from Mt. Xinu
In particular, what are the stengths and weaknesses of each?
If we decide on BSD 4.3, how do we ever get support (or are we supposed to
become UNIX gurus)? Is Ultrix a decent version of UNIX? Does it fully support
4.2 networking? Why does Mt. Xinu have such a good reputation? Should we go
with DEC (for their expertise with VAXes, supported products, enhanced UNIX)
or Mt. Xinu (for their UNIX expertise, etc.)?
We would be eternally grateful for any information (particularly from users
of these systems on other DEC machines). Please respond directly to me.
Thanks...

We have two uVaxes running Ultrix, with much 3rd party hardware. Our level of Unix "expertise" is middling - certainly, no one at the caliber of many of the people who correspond on this newsgroup. Our experience with DEC's Ultrix software support has been abysmal. We have yet to receive a proper/useful/correct answer to a query. We also purchased the recently-released "VAX Fortran", since we have one large home-grown stat package that can benefit from the superior performance; this also has lead us to use DEC's "jacket" routines (which provide inter- faces between "VAX Fortran" modules and modules written in f77, C, etc). We are currently working on work-arounds to work-arounds due to problems with both; DEC has been able to do little more than promise to check things out, admit problems, and ask us to submit SPR's. The stat package we are convert- ing, by the way, runs under DEC fortran 77's under TOPS-20 and VMS. The documentation is sloppy. We seem to have run into an inordinate number of instances of command parameters that don't exist, or exist but are not documented. The backup material is apx. 1/2 Berkely/AT&T papers and 1/2 DEC-produced. The former, which is, of course, often included by vendors, is useful - but much of it is out of date from a day-to-day prectical stand- point. The latter tends to be shallow. Overall, there is very little that provides an understanding about the interaction of Ultrix and the hard- ware (tho I have seen this in other vendors' documentation as well). Overall, I am satisfied with the hardware and DEC's support of it- which includes the third-party equipment. But I am very unhappy with the software support. If I were paranoid, I might come to the conclusion that ................... greg pavlov, fstrf, amherst, ny
