NY Stock Exchange Moves To Linux 272

Posted by kdawson from the bye-bye-big-iron dept.
An anonymous reader writes "Even the old mainframe strongholds, the financial markets, are moving away from big iron. The New York Stock Exchange is one of them, as it's leaving the mainframe for AIX and Linux. They're doing it to save money; it seems that transactions are going to cost half as much on Unix and Linux as they did on the mainframe." The first phase of the transition happened last Monday.

      Other zOS skills are more useful, particularly the Sysprogging skills like JCL, console commands, rexx, TSO and ISPF.

      The Linux skills to have in this area are the System Admin ones like bash scripting, setting up Apache and other server stuff, using ssh, etc.
  • Well, the migration strategy seems interesting, although not especially surprising; they've eschewed emulation strategies that might incur a performance penalty in favor of some company that actually recompiles the old COBOL and IBM JCL code for modern architectures and does a lot of in-house QA (and, one assumes, has really good support...). They're using smaller IBM AIX servers to actually run the code in the new system, with the HP Linux machines basically doing all the I/O and general feeding of data.

    I'm a little surprised that IBM didn't manage to sell them on a new mainframe, or at least on its own clustered solution; or that they didn't ditch IBM completely and go with somebody else (what I'd suspect if somehow someone at IBM had really stepped on the wrong foot).

    There's not a whole lot of information in TFA about their old system, which actually sounds like it must be fairly neat; it's only described as a "1,600 MIPS mainframe" and then from context it's clear that it's an IBM of some sort. Another surprising thing is that they complain that the software licenses for it, among other things, are prohibitively expensive -- you'd think that IBM, in danger of losing a mainframe customer completely to commodity kit, would cut them some sort of a cheap-or-free deal on the software just to keep them around and on the support contracts. (I really gotta wonder if someone really boned this up; I mean, if you can't keep a mainframe contract at a place like the NYSE, really, what are you doing?)

    I think the author of the article got into a tangent with him about how many transactions they do, and what their operating costs are and then incorrectly made the correlation that there is a cost-per-transaction from a computing stand-point. That can't be true. You don't insert fifties into the A: drive.

    Look at it this way: If they make the big switch, and all of a sudden they can handle double-the-transactions per day - that would halve the cost of transactions. Only there's not going to all of a sudden be double-the-transactions. They're still working with the same number of transactions.

    If they halve their staff, and they do the same number of transactions than that halves their costs. But what if tuesday is a slow day, and they only do 60% of their normal business? They're still paying for all the staff, electricity and third party support.

      These machines will (in all likelihood) have very lean customized kernels built for specific hardware device profiles. Wouldn't surprise me to see customized drivers written specifically for said hardware. I can't speak for the HP team, but the SIAC dev teams have some damn smart and capable folks on them. They'll be able to get done
    • Mainframes are unique in their integration and optimization between the hardware and the operating system they run. It gives you a level of performance, integrity and fault tolerance which cannot be achieved by taking generic hardware and sticking Linux on top.

  • I thought it was well-known that the mission critical NYSE back-end database ran HP NonStop hardware and software (formerly Tandem). The NYSE has lots of systems...I'm sure they are moving some stuff to x86 Linux, but I really doubt they are replacing the NonStop systems with Linux.

    I worked at a world-wide bank that ran its entire operations on a pair of ES/9000 mainframes from IBM and, while insanely expensive, requiring a full-time staff of 12 people (for each machine), requiring a separate floor on the building, etc. etc., I have still never seen anything that came close to the horsepower these things had. They simply wiped the floor with everything else out there.

    As an example, it calculated a person's balance by starting with their opening balance, then went down the vsam file, adding and subtracting amounts, till it reached the bottom and gave the total. This process was instantaneous, even given all the other things it was doing.

    Sure there are better ways to do it, like storing the data in a real RDMS, using a trigger to update a "balance" field so it's a quick query instead of a lot of calculations, etc., but I wonder if so much of what we do is simply making the best of essentially a hardware deficiency; the baddest Intel-based Linux box probably couldn't do what this 20 year old mainframe can do, so we make it do the same thing but in different ways.

    Working with the mainframe programmers, all Cobol folks, made me think always of that great Dilbert cartoon of the smug Unix guy giving Wally a nickel and saying "get yourself a real computer" ... these people did not worry about efficiency for the most part simply because the machine was so fast, they didn't need to.

    So ultimately it's too bad that mainframes, for all their horsepower, really do resemble, to a certain extent, the moniker "dinosaur" in that their mammoth bulk simply couldn't get them out of the tar pits of cost and space.

    The coda to this is that, once you've used JSO on TSO, every Unix command looks like it's written in the Queen's English by comparison.
  • I never trust cost savings estimates by business leaders.

    They get raises, bonuses and promotions based on cheery estimations and then leave before the full costs come home to roost.

    Still- linux should be a lot less expensive so they have a chance of saving *some* money.

    As someone who started their IT career as a mainframe operator in the early 90's, then moved on to UNIX/LINUX It would be very interesting to see if the cost savings actually pan out. Computers don't stop doing the job they are doing just because they get old. Besides, modern "mainframe" computers are all microprocessor based (no more cabinet sized processors) just like all other computers. OS/390 (or whatever IBM is calling nowadays Z...something?) is just about bulletproof.

    I would of LOVED to be in on the powerpoint presentation that convinced NYSE that that dumping their current platform was THE thing to do. It must of been dynamite.

      We are migrating Cobol mainframe applications from OS/360 to micro focus Cobol on i86. For once MC support is much cheaper and hardware maintenance is also cheap compared to IBM mainframe.
  • Rest assured, worried investor, that these savings will be directly passed on to the stockholders of the exchange. You need not fret about dealing with lowered trade prices from your broker any time soon.
