OK, not to start a war, but those of us that have worked on both Unix and
VMS know (or should know) that there are significant advantages (and
therefore, disadvantages) to each. For example:
Advantages
VMS
--------------------------------------------------------------
User administration
Queuing system for print/batch/server/custom.
Flexible object security with or without ACLs.
Error messages.
Asynchronous system traps.
DCL's structure
Logicals!
Stability
Ability to enable user and process specific resource quotas.
Unix
---------------------------------------------------------------
Speed, speed, speed
No-or-low-cost software RAID 1 and 0.
Choice of shell or shells (flexibility)
Numerous addons available for everything
Stability
Disadvantages
VMS
---------------------------------------------------------------
Proprietary (one vendor)
Percieved lack of available software
Inability of non-VMS types to properly or optimally program on
VMS (see Oracle's DCL procedures and hokey setup).
Slower I/O than Tru64 on same hardware.
Software RAID 1 and 0 is a cost option.
DCL's structure (!)
Unix
---------------------------------------------------------------
Many shell commands are inconsistent (e.g output from ls and grep)
Lack of flexibility in object security without using ACLs (e.g.
no delete bit in file access)
User management
Queuing
Generic error messages
That's just my take on it. I started working with VMS around 4.5 back in
'87/'88. I now work mostly with HP/UX 11.0. I like Unix, but I do sorely
miss the overall structure and consistency of VMS.
I don't buy the "the rest of us are on *NIX" argument, either. "Everyone
else" is on Windows and that sorry excuse can't hold a candle to a real
server OS. </flame: off -- run for cover>
