    What makes something a "real unix" anyway?
    The Open Group, current owners of the UNIX trademark, manages a collection of standards and certification processes which a product must meet to be allowed to call itself "UNIX". For instance, here's a short blurb about the UNIX 98 standard:
    The UNIX 98 Product Standard is a significantly enhanced version of the UNIX 95 Product Standard. The mandatory enhancements include (1) Threads interfaces, (2) Multibyte Support Extension (MSE), (3) Large File Support, (4) Dynamic Linking, (5) changes to remove hardware data-length dependencies or restrictions, and (6) Year 2000 changes. In addition the following optional enhancements are included: Software Administration facilities and a set of APIs for realtime support. This Product Standard includes the following mandatory Product Standards: Internationalized System Calls and Libraries Extended V2,Commands and Utilities V3, C Language, Transport Service (XTI) V2, Sockets V2 and Internationalized Terminal Interfaces. In addition, it may also conform to the Software Administration Product Standard.
    Thus, real UNIX systems have much commonality, despite their individual quirks and differences in implementation. The propagation of open standards and a UNIX "brand" which must conform to these standards makes everything easier, from porting software to system administration. AIX 4.3 is a very, very different system than say, Solaris 2.8, but because they are both UNIX products, you can be guaranteed of certain behaviors and the availability of certain interfaces, daemons, libraries, and whatnot. Vendors were willing to go through the licensing/OSF mess in the late 80s in order to make possible the Single UNIX Specification available today.

    The fact that so many Linux users can remain so ignorant about the system which Linux ripped off is astounding.

  • All BSD derivates (NetBSD, ...) have emulations for linux for a *long* time. They trap Linux system calls and map them to native calls, which works fine to runs applications like Netscape, Quake, Oracle, etc.

    Dunno what the big fuzz is here. ;-)

  • a [truly enterprise-ready] Linux kernel."

    and what he really meant to say;

    "It will be three years before linux has all the wizards that windows has"

  • Why wouldn't they just recompile the GNU userspace to run natively?

    No, this is an incredibly shrewd move to allow UnixWare to run all of those closed source binaries that are built for Linux like... umm... well I can't think any right now, but I'm sure there are loads.

    Oh wait, I got it! Quake!

    The Bible is not my book, and Christianity is not my religion.

  • I don't know what it's like in the States, but in Australia the only commercial Unix that is alive and kicking is Solaris. HPUX and SCO are on their death beds. Digital Unix, AIX and Unixware are nearly unheard of.

    Here in the states, I work in a shop that is about 50/50 split between HPUX and Linux, with a smattering of FreeBSD and Solaris (well, and file/print sharing is mostly NT, but I hardly ever have to get anywhere near it). It used to be that HPUX ran all the workhorse applications, but recently we've been moving some pretty large web/database applications to Intel/Linux. The HP9000s aren't going away anytime soon because, from a hardware perspective, they're more mature, reliable servers in a lot of ways. But as an OS, I think everyone has been a lot happier with Linux (even the BSD guy who still complains that he can't do a 'ps -ef' in Linux).

    Overall, I agree with you that Solaris is the biggest commercial Unix by a large amount. Though there ARE plenty of people out there using that Sun hardware to run Sparc Linux...

    As for Unixware, I'm not sure I see the point of Linux compatibility, but I do have a certain respect for Unixware as an OS. I admined a few Unixware boxes back when it was still a Novell property, and it was a good, by-the-book SYS5 implementation with a decent packaging system added on. This was back around '95, when most bosses would just sort of give you an amused look if you suggested running any sort of production server on Linux.

  • What does Linux need for the enterprise? Well, according to Love in an earlier interview, Caldera would like to make UnixWare's large file system support, synchronous input/output (I/O), the UnixWare API, extended developer kit and multipath I/0 available as an optional open source add-on to Linux as well as bringing Linux binary compatibility to Unixware.

    Personally, I think Linux 2.4.1 is as enterprise server ready as you can get, but I can see how UnixWare's file support and advanced I/O could make it even nicer--especially if you were running massive DBMSs.

    For more on Caldera's UnixWare/Linux plans see:

    I suspect this is not the definition used by SCO when describing the advantages of UnixWare.

    In any case, IBM can deliver Linux based solutions with that kind of power, and better support.

  • what remains to be seen is whether enough customers are interested in the hybrid commercial / Free software system to pay the premium for it

    There's also a huge installation base of Unixware systems that Caldera would like to hold on to. These are mostly telephone embeded systems. When AT&T was a monopoly, computerized switches and voice mail systems were mostly Western Electric 3B systems running Bell Labs Unix. Lucent inherited that business, and even though they're not a monopoly, they're pretty strong. The systems now run commodity processors, but the OS is still Bell Labs Unix -- or rather its commercial successor, Unixware.

    Do you have an AT&T or Lucent phone on your desk? Audix voice mail? Believe it or not, there's at least one Unixware box in your building.

    Now, I don't know how tied Lucent is to Unixware. But they must be a possibility, however remote, that they would switch to Linux: no license fees, bigger developer community. Plus Lucent has competitors, some of whom do use Linux. Caldera needs to offer Linux compatibility just to hold onto all those license fees they get from Lucent.

  • I dunno, it's got all of the standard Unix command line utils and then some. I'm not sure what you're missing. Maybe they don't stick as much third-party stuff on there by default as, say, Redhat or Mandrake do, but then again I don't think they should. Even as it is, they install a ton more 'extras' than any commercial Unix or any of the BSDs. If there's any other things you're missing you just grab the rpm's and away you go. I can't think of any standard-issue core components that would be found on any Unix box that are notably absent in Caldera.
  • In all fairness to Caldera, the CEO wasn't comparing linux to win2k. He was comparing linux to other unix OS's.
  • "It will probably take another three years to build a [truly enterprise-ready] Linux kernel."

    So how many years will it take to build a truly stable Linux kernel? Six? Seven?

  • Well, that is an answer. But I don't think it's a great answer.

    If you're an ISV selling a niche product or products, you pretty much get to say "Customer, you will run SCO" or "Customer, you will run Linux". They just want you're application, they don't care what it runs on. They're paying $$$ for it to carry out a, presumably important, function, where there's little competition,

    If it's an established, generic product, like a database server, you'll have a SCO port anyway. If not, you probably don't care about them.

    If it's a new, mass-appeal product, like an RDBMS or a web server or something, OK, there might be some people running on SCO. I doubt it. Oracle doesn't seem to do SCO, for instance. But I don't think this is really 'news for nerds'; more like 'news for one proprietary Unix vendor who might be able to scrape two or three more years of life from it's dying product."

    I don't have much experience of SCO, my company used to use it for telephony but it's gone now because the software provider was phasing it out; we now run NT. But everything I've read suggests it's used in niche markets, like telephony, where the vendor says "This runs on SCO, take it or leave it."
  • UKP sounds a whole load more intersting than LKP. I can at least see the point :)
  • No, this is an incredibly shrewd move to allow UnixWare to run all of those closed source binaries that are built for Linux like... umm... well I can't think any right now, but I'm sure there are loads.

    Exactly. Not user apps, though--server utilities. A company like Oracle would love to reduce the amount of time they have to invest in porting to different Unices... and more and more, these days, Linux is among the first ports that get done; IT managers ask about it a lot, whereas UnixWare hasn't built up much mindshare yet.

    Well, now the Oracles of the world can port their stuff to Linux, and it'll Just Run on UnixWare--but it'll run better, from a gigantic-datacenter point of view, because UnixWare's multiprocessor and clustering support kicks Linux's ass on equivalent hardware. (Meaning no disrespect at all to Linux, which kicks UnixWare's ass in lots of other ways, but this sort of thing is exactly what UnixWare was developed and optimized for, and for all its flaws it's got an excellent kernel.)

  • Linux gives you *no* options about which toolkit to run. You have to run whichever one your apps use. If you're app uses more than one, too bad, you have to run that one. Plus, more toolkits means more incompatible features. Printing, for example. If you run GNOME and KDE, you've got three printing layers, the one in X, the one in GNOME, and the one in KDE. All of that is totally wasted, redundant code. It saps performance and keeps apps from interoperating. Take, for example, the case of EVAS. From my POV, the Linux desktop has some good features. It has the nice, fast network model and multi-media API in KDE, it has the broad application-base (GIMP), corporate support, and visual quality (I like GNOME's art better, KDE is too cartoony) in GNOME, and it has nifty features like accelerated desktops with EVAS (enlightenment.) Unfortunately, no-one app can take advantage of all of these features, because they're not in the same GUI environment. That's just a waste of a lot of good code. Things would be so much nicer if they'd unify the toolkit APIs and work on inerchangable back-ends. The API could be something like GNOME's that could have lots of language wrappers, and if it were well designed, the developers couldn't complain too much about being forced to use it.
  • That's a real nice troll there: Look at me, I can whine about DLL problems in windows cause it had them with the old versions but its somehow still relavent cause I'm a linux bigot.

    Linux has DLL problems too, but we call them library versioning problems. Ever try upgrading your glibc version? Notice all the dependency problems when you try to do an apt-get dist-upgrade. There must be SOME reason that it held back a lot of my X font packages. Maybe its VERSIONING ISSUES.

    Oh, my, 54000 bugs in an operating system with millions of lines of code.

    Now, lets add up all the bugs in all the pieces of free software that microsoft would consider part of the operating system. That's kernel + x + a handful of servers + window manager + file manager. I bet it's darn near 54000 total if not over.

    I've been running Win2000 since I installed it three weeks ago without rebooting for anything but driver installs. No blue screens thus far. And I abuse the hell outta my machine. AND I'm running beta drivers (video and dvd).

    And it is a shame how much Microsoft is trying to emulate the Mac look-and-feel. Cause, I mean, they have a Desktop. And Windows. And menus and toolbars. And translucency. Just like a Mac.

    Unlike linux, which has a Desktop. And Windows. And menus and toolbars. And is still working hard on ironing out the translucency. AND HAS AN AQUA THEME FOR GTK/KDE/GNOME/etc...

    I also run Debian. I don't like Microsoft. But I hate people who troll with this kind of drivel. Linux is perfect and Windows sucks. Wait, that's a complete lie. Windows is GREAT at some things. Linux SUCKS at some things. In other words, they both have their strengths and weaknesses. Linux is not perfect. FAAARR from it. So is Windows though. Life with it. Open your eyes. Stop using slashdot as your primary source of news.

    The fact that you even mention NT as an example of an "enterprise-ready" system shows that you have no idea what you're talking about. NT5 only runs on x86 hardware, which I don't acknowledge as a platform for doing anything but playing Quake 3 or running "myhomepage.com".

    "Enterprise-ready" is an E10k with 64 CPUs, 64GB of RAM, a and multi-terabyte SAN. "Enterprise-ready" is an RS/6000 farm. And to me, "enterprise-ready" is real UNIX. Linux lacks scalablity[1] on non-trivial (read: non-x86) hardware and widespread commercial software support. And decent threads! (Ask anyone who's had to port large UNIX software packages to Linux.)

    Another problem with Linux is that the historically best distributions (such as Debian) have no corporate accountability, while the commercially popular distributions (such as Red Hat) are buggy-as-hell and dumbed-down.

    Don't get me wrong, I use and enjoy Linux... but I'm a UNIX guy at heart and it pains me to see companies such as SCO say that Linux is competitive with UNIX, which IMNSHO it is not. Real UNIX is not only guaranteed to work better than anything else on your vendor's non-trivial hardware, but it will also comply with a large number of open standards that Linux hasn't even approached yet. Each of our ten RS/6000 cages contains about $800,000 of hardware; the cost of UNIX is insignificant, and the advantages are innumerable. The only place for Linux in our datacenter is embedded in our routers.

    Offtopic: While I am a UNIX zealot, I like much of RMS's philosophy and use a lot of GNU software. In fact, I refer to my UNIX boxes as "GNU/SunOS": SunOS/Solaris with a full GNU development suite. Incredibly slick. Free Software rules, Open Source drools.

    Oh well, no one on this site listens anyway...


    [1] And on x86, it only scales well to 4 CPUs, but anyone who is going to waste their money on a (NUM_OF_CPU >= 8) x86 box deserves what he gets.

  • Part of being "enterprise ready" is that you need to guarantee 100% quality to the customer/client. I'm _not_ saying that Linux can't provide this. However, the businesses that want to provide such a guarantee need their "insurance". This "insurance" is typically a vendor guarantee.
    If E-garbage-mart run in a Tandem system they _know_ that if they can't run their business because of a problem with the Tandem servers they know that it'll be fixed in 4 hours, or they get compensation. I believe DEC used to offer _1 hour_ onsite support in some parts of Europe (Germany).
    (This means that they needed a dozen sites in the country with people on call 24/7.)
    If companies offer cold hard "99.995% uptime" guarantees on Linux systems with compensation terms, then people will consider them Enterprise ready. Not one line of code needs to change - simply that fact that someone is willing to _fiscally_ underwrite it.

  • Threads on Linux are just fine. Did you actually use a pthreads library based on clone, or did you use one of the crappy userspace thread libraries?

    Also, which "open standards" do "Real Unix" operating systems support that Linux does not?

    What makes something a "real unix" anyway? Costing money? Is BSD Unix?
  • I would venture that ANY system running on an x86 platform is not "Enterprise" level. That being said, the work IBM is currently doing with Linux on the mainframe is not only intriging, but provides a very legitimate chance for Linux to fulfill the promise of Enterprise level functionality.
  • The original quote was

    "It will probably take another three years to build a [truly enterprise-ready] Linux kernel."

    He seems to be focusing on -just- the kernel, apps be damned.
  • glibc version problems are of far, far less importance than windows DLL problems.

    Besides, recent glibc versions are supposed to be binary-compatible with older 2.x ones, no?
  • LKP is a kernel based rather than a userspace emulation such as LKP.

    I had a meeting with SCO/Caldera last week and as well as LKP they have UKP in the labs which they 'may' release . i.e. A Unixware kernel Personality to hook on as a module into the Linux kernel .

    Kinda interesting, but I agree the 'why?' question sticks out kinda large !
  • Thats what you might think if you never used the command line. Someone who always keeps an rxvt open would be less than thrilled with the lack of command line applications, as I was.
  • I don't suppose it means anything that Cray's next supercomputer is going to be an Alpha Linux cluster...

    Honestly though, Linux lacks the tools to make this sort of thing a straightforward setup. Configuring Linux from the ground up gets you there, but that's a tedious process that most people don't want to go through. ("What, Linux from Scratch? Ummm...can I have ReliantHA, please?") Also, as of glibc 2.1.3, the basic GNU/Linux system as a whole was not completely POSIX compliant. Some of the missing POSIX features (like atomic file locking, which finally works in glibc 2.2) are actually very good features to have ;)

    I don't know what Caldera's claim on Linux threads vs SCO threads is all about. If Linux threads don't actually share the code segment's space (which I doubt) then there could be a performance hit, I suppose. A lot of people insist that the Linux __clone() call (the basis for Linux threading) is not "real" threading, but I fail to see where it differs or takes a significant performance hit.

  • It would be nice if the kernel sources could be opened, but from last week's LinuxToday article (re: the same subject) one concludes the following:

    1) There's a lot of code in the Unixware kernel that's licensed from third parties and hence can not be opened by Caldera

    2) Even if the sources were opened, odds are nobody would use them. This isn't because of any grudges or snobbiness; it's a matter of the Linux kernel and the Unixware kernel being somewhat different at the levels where the opened up sources would benefit (non stop clustering, SMP, etc.)

    I doubt that there's much that can be done with the Unixware kernel sources when taking these two items into consideration. It would be nice if the sources were opened, but I doubt it would accomplish much.
  • "Another operating system"? It's Linux. And it's Unixware. Both have been around for years. Caldera's merely allowing one to run on top of another. The libraries, APIs, whatever should be the same.

    ???
  • Funny stuff. I recently tried to upgrade the glibc 2.2.2 test release to 2.2.2 and it broke ls of all things!
  • I can whine about DLL problems in windows cause it had them with the old versions

    What are you saying that we don't have those problems anymore? Boy is that wrong. Trust me, I work on the front lines (mid sized pc repair shop that mostly services family computers) and Windows has not improved one iota in the stabiilty department, if anything's it's gotten worse.
  • (even the BSD guy who still complains that he can't do a 'ps -ef' in Linux)

    My good friend Wes [slashdot.org] taught me that you can set the I_WANT_A_BROKEN_PS environment variable in Linux to allow ps-ef. Here's a quick snippet of the Linux ps man page:

    Set the I_WANT_A_BROKEN_PS environment variable to force BSD syntax even when options are preceeded by a dash.

  • Isn't this just an industrial-strength version of lxrun, which was written for Unixware back when people actually used it?
  • That's lxrun [sco.com], by the way. Dunno why it ate the link.
  • It's easy. One port, two platforms.

    Think about it. If you're an ISV and you want to port your multi-million $$ generating database system to Linux, but you don't want to give up the power behind your Unixware version, you can port to Linux and run the Linux version on both Linux and Unixware w/ LKP. You only have one port to support and maintain, you get revenue from two markets (does anyone using Linux actually pay for software? I don't know of many).

    All of this, just by adding LKP on top of Unixware. What's not to like?
  • True, but (if Unix means Unix-like) you don't mean commercial Unix.

    You mean closed source or proprietary Unix. Red Hat, Caldera, Mandrake etc are all commercial entities whose Unix-like OS exists for the purposes of making them money.
  • Real Server, Windows Media Server (yes), about ten databases unavaliable on SCO, some scripting language plugins for Apache, and indeed, every Loki game, RealPlayer, Flash Player, etc on the desktop. That's off the top of my head. There are more.

    Some Linux users use it for the same reasoin they use closed soruce apps on it: because its the best tool for the job.

  • as I can run gnome stuff in KDE and vice versa.

    But you can't.

    * xdnd is poor, and doesn't often work. Try xdnd from konq FTP to a gnome desktop.
    * panel applet imcompatibility
    * mime type incompatibility
    * doubled learning time from two sets of common controls, completely diffferent visual styles
    * Component level incompatibility
    * A stack more reasons I can't think of right now

    The integration between the two is, frankly, a load of shite. yes there's room for two, but now with the current l;evel of incompatibility. Lackk of consistency hurts the Linux desktop far more than competition is currently enhancing it.
  • This joke is too obvious to pass up...

    Unixware that runs Linux. I guess that would be called??? Lunixware!?!?

  • This is totally typical of a Slashdot article. Most of the punks miss the point thus showing off their lack of research and understanding. I realize this will most likely be moderated down, but oh well, Caldera LINUX supporters will never win on any Andover site. Truth. Anyway, the thing to understand here is that while the UnixWare OS is closed and does have some old software on it, the one thing is does have is a good enterprise level kernel. Now some of you mentioned lxrun and emulation. Not the case here. The LKP product is Linux. Let me say that again, it is Linux. It is Linux leveraging the enterprise power of the UnixWare kernel on the back end. Some of you also mention that the Linux kernel supports so many processors and so much memory. As far as the UnixWare kernel is concerned, I don't need to say anything. As for Windows 2000, come on, can we talk about stability here? I mean really. Anyway, while Caldera is taking steps to help the Linux industry, what is redhat doing? Making their _linux_ proprietary and trying to take over kernel development, and... Think about it. Unix kicks Linux's ass in some areas.. Linux in general kicks ass so this will only help things kick more ass. Oh and one more thing, it is Linux. Get your facts straight before you go off on something you don't understand and makes you sound like an idiot. cyco
  • Wow. with the number of businesses already using Linux, that's a rather interesting statement. (3 years for an enterprise-ready kernel)
  • in the future of open-source/free software, I'd expect to see releases of Unixware source code to the developer community under a open license, wouldn't you?
  • Why should we care?

    I'll assume this is a legitimate quesiton, and not trolling

    We should care because of the reasons Ransom mentioned in the article, however much we might disagree with his perspective. UnixWare is an enterprise level OS and has been for quite some time. It is more mature than Linux and has several features Linux currently lacks. (again, see article). If the source code for UnixWare was made available to the Linux development community, those features could be more readily be implemented in the next version of the Linux kernel. Open-source 101

  • In the UK Solaris is the major UNIX, with HP-UX some where out there. However AIX does have quite a large presence here, especially in the banking, retail and telecoms sectors. I think Germany also has a high penetration for AIX (some one else will need to confirm that, but I know of at least 1 major German bank that are RS/6000 reliant)
  • Why? Having several options for graphical toolkits really can't hurt as long as I can run gnome stuff in KDE and vice versa.

    I can see why people would prefer Qt (I do), but I can also see why people who have never done C++ would prefer gtk rather than learning a "new language" - why not give people both (or even more) options?
  • Digital Unix has its niche here in the UK, and is used extensively in academia (esp. maths and physics) because:
    1. Its comes on very fast uniprocessor machines and parallelising code is
      1. Hard
      2. Dull
    2. Has an excellent Fortran 95 compiler
  • The "big fuzz" is that this has never been implemented in a complete fashion for Unixware. It's great that *BSD has this, but that doesn't benefit Unixware users very much, does it?
  • Well, there are big enterprise systems running Intel. And i can show you a picture. In the Dec 2000 issue of Wired, there is an article on Supercomputing. On (i think) pp 244 there is a photo of Ford's data center. In the picture (mostly hidden) is a very large Unix system running on Intel silicon. It's under the Sequent sign.
  • x86 scales to 8 fine, IIS 5.0 (I know, there is no reason to have an 8 way web server) and Exchange 2k scale that high fine. Unisys did 8000 E2k users per partition a 4 way partitioned 32 cpu machine in an active-active cluster.

    Just get him the right version of 'ps'. I run SuSE 7 and the 'ps' that comes standard with it will do 'ps -ef' just like any good old SysV unix.
  • No free unix can be a unix as far as The Open Group is concerned, since they must include CDE, and CDE is commercial software.
  • Family Computer?

    Well there's your problem. Of course THEY haven't advanced at all. Win95 was their last advancement in that product line. Win98/ME are just repackages of 95. I'm talking about their NEW OS. Windows 2000.

    We run Win2k on a bunch of computers are work and most of my friends run it at home too. I use my for a web/ftp server and as a gaming/dvd machine. It has never crashed. Not even once.

    Yes, 2000 DOES still have DLL problems. They aren't NEARLY as bad as they used to be. I was just trying to point out that Windows isn't alone in these problems. Linux has them too. I haven't had any yet with this box though. Mostly those problems are with their home product line.

  • Anybody else notice that the Slashdot rendering of the Caldera logo looks a lot like half of Mickey Mouse's head?

    Whatcha tryin' to tell us, Taco?

  • Not from what I have seen. I worked as a unix consultant to the Australian financial industry up until a year ago and I saw heaps of AIX and HPUX boxes. My current workplace (an energy utility) has a large computer room full of IBM SP boxes running AIX.

    You're right about SCO and DGUX - the only times I saw those two were when they were being replaced by Linux or AIX.

  • This is almost amusing. I mean, I know that since they bought SCO they had to do something with it...but who are they fooling?

    Sure, as people have noted, there's still lots of things that Linux could do better. Both it and the
    8*86 platform are not the best platform for true high grunt performance on a mission critical task.
    Most Linux people know that, albeit they don't think there's anything that will stop those abilities maturing over time.

    ...but...

    Sco's got the same problem! Sure, they used to be the `leading unix on 8086' but that doesn't help them compete with Solaris or Aix. And while they might try and snag the title `unix' for themselves they don't have the marketshare, mindshare or money to seriously challenge IBM or SUN. There's lots of installed SCO systems, but they're not running corporate data-centers.

    And, for those things linux does well (at the moment), like providing cheap servers and good desktops, they can't compete with linux.

    So, the true message is, "we realise that most of the new apps are linux apps, but we want to keep unixware alive".

    (and yeah, I know I should be Caldera unixware instead of SCO...old habits).
  • Yes, thanks... we call that "semantics." I call it a new OS cause it's the newest version of the NT line and also the first Microsoft OS to be a supposed merger between the home and business lines. Plus a deal of it was rewritten.

    You call it and "old" os cause it's based on earlier work. Would that not imply that linux kernel 2.4 is not a new kernel? It's obviously new, in that it just recently came out. But it's obviously old in that it is based on prior work.

    Again, semantics.

  • I recently saw a big, brand new Lucent phone switch where someone had foolishly plugged in a console, logged in as root, and left.

    The OS was identified by login as something like "Bell Labs System V UNIX". Which is closely related to SCO UnixWare, but not quite the same thing.
  • I just want to point out... SCO is the root of all evil.

    Wow. with the number of businesses already using Linux, that's a rather interesting statement. (3 years for an enterprise-ready kernel)

    An enterprise-ready kernel implies one suitable for running banking systems & very large database systems on. It would also imply a featureset much like Digital Tru64 or Solaris, with failover clustering etc.

    With the best will in the world, I'm not sure Linux is currently at this stage, and I do not think it will be for a few years either.

    Many businesses deloying Linux as web servers, firewalls, or file servers does not make Linux an enterprise-class platform.

  • What part of "Enterprise-ready" is not included in the 2.4 kernel?
    8 or more processors? Check.

    64 GB RAM? Check.
    I would like to take this opportunity to point out that Windows 2000 Server only supports 4 CPUs and 4GB RAM, and even Advanced Server only supports 8 CPU's and 8GB ram. (You'd have to shell out big $$$$ for Datacenter to get the 64GB RAM support that 2.4 has).
  • Excuse me? The same Windows that has .DLL problems with darn near every application they put out? The same Windows that had 54,000 bugs with the release of ME? (excuse me, unresolved issues)

    If everything switched to the Microsnark standard, every system would be getting blue screens of death from such complex operations as moving the mouse or opening a second application while a first one is still running. Various distros of Linux may have their problems, but I'd rather not go to a M$ desktop standard (no matter how much they plan on making it look like a Mac).

  • It still strikes me as kind of odd that we are working towards video games in Linux when we still haven't quite figured out how to do a proper or a unified UI. I mean, we're still in-fighting over which graphical toolkit is better, let alone which mode of IPC is better... In-fighting only leads to branching, when instead we should be working towards debarking this tree of development... grrrr...
  • The Linux 2.4 kernel is not everything everyone is claiming it to be and still does not have a lot of the features the Unix kernel has had for years. It will probably take another three years to build a [truly enterprise-ready] Linux kernel.

    So, what Caldera is basically saying is, that they need at least 3 years to recoup their investment in SCO... that statement should scare the pointy hair types for at least that long while the tech guys scurry to gather facts on why they should use Linux over SCO.

  • Enterprise ready doesn't mean merely 'suitable for use by a big company with a big budget'.

    Big companies use Win95 still.. does that make it enterprise-ready?

    And just cause it runs print servers or departmental file servers doesn't make it enterprise ready either.

    Do banking systems run on it? Real-time transaction processing for stock markets? Critical insturment control for nuclear power plants/other major industries? No....

    That's what they mean by 'enterprise-ready' in this context; the ability to stake the data of your whole enterprise on it.

  • No-one seems to be asking, what exactly is the point of running linux binaries on the SCO kernel?

    Most free software will build on SCO, I'm sure. And SCO has been round long enough to have it's own proprietary market.

    OK, I've not seen Quake III for SCO. But, apart from games, what is the point of this? I don't get it.

    About a year ago (before Caldera bought SCO) I went to the SCO download site and downloaded a module that allowed running of Linux apps on SCO OS5 and Unixware. This is sorta old news. I ended up installing a second box running Linux. Given logins on both boxes, most of the users use the SCO box for stuff that could be done on either box. Most of the admin stuff moved to the Linux box (DNS, apache, fax).

    I've tried their most recent release and was extremely impressed with it. It is without a doubt the most polished and professional commercial Linux distribution out there. It seems they have zero hacker credibility, but on the other hand I'm starting to think that maybe that's not necessarily a bad thing :) ('the hacker community', a la ESR's 'tribe' *blech* has gone way downhill in recent years, if it ever really existed as a cohesive group to begin with, being ever more dominated by the script kiddie/perpetually-enraged-teenage-Slashbot/bearde d-middle-aged-zealot-living-in-mom's-basement/just -plain-rude-and-annoying-person consituencies).

    Installing it and administering it, you really get the feeling that a whole bunch of people were paid a whole bunch of money to spend months and months going over every inch of it, dotting every 'i' and crossing every 't', making sure everything worked together properly and that everything was consistent and uniform and complied with their policies on how things should be laid out. With Redhat, there's always the feeling that it's just a bunch of stuff that they threw together and stuck on a CD.

    I use Debian but I would not hesitate to recommend Caldera to someone who wanted to deploy Linux in a business environment (or just for personal use). It's too bad that they aren't more popular than they are (anyone know the market share percentages for the various distros? Not that it matters, it'd just be interesting to see the figures).

  • Maybe this will be the GNU userspace on the Unixware kernel, which would be OK. The major niceness of Linux has always been its userspace moreso than the kernel itself. Lots of people install a load of GNU software on their Solaris boxen for this reason. It's the final patch to make Solaris a usable system, so to speak...

    Or maybe they'll do something stupid and just emulate Linux with Unixware...

  • Apps that need it:

    - Payroll Processing.

    - Databases (no, not mysql)

    - Financial Processing

    Why not use distributed processing?

    - Complicated

    - High Latency for transactions

    - High licensing costs. (why license software when you can buy hardware?)

    - more staff

    - Complicated
  • POSIX compliance isn't all it's cracked up to be. Linux would do well to focus on things like supporting end user locales and languages that POSIX doesn't support at all.

    I mean, cmon! The POSIX "standard" locale charset doesn't even have 8 bits! --mazor

  • I would like to take this opportunity to point out that Windows 2000 Server only supports 4 CPUs and 4GB RAM, and even Advanced Server only supports 8 CPU's and 8GB ram. (You'd have to shell out big $$$$ for Datacenter to get the 64GB RAM support that 2.4 has).

    I don't think the issue is how many processors you support, or how much memory can be addressed ... it's much more than that.

    Where are the enterprise-level apps?

    I would agree than Win2K DC edition is hardly enterprise-class either!

    On an important note, there are NO Enterprise-class systems which do not use proprietry hardware: it's the only way companies can guarantee resiliancy and uptime. The intersting point is this: how the hell does Linux achieve this when it's at it's best running on Intel-based kit? I realise it's been ported to pretty much everything, but that's not the same thing as being resilient on every platform it has been ported to!

Whenever people agree with me, I always think I must be wrong. - Oscar Wilde
