    No wonder you find everyone stupid, you clearly have extremely low metacognition skills and you have no clue when you're out of your depth.

    I take your inability to answer a single question I posed as proof that you don't know what the fuck you're talking about.

    Seriously, what the fuck do you do for a living? I'm imagining a sad office tech who keeps getting called over to reboot the boss' SIP phone or clear out the malware on the demo laptops picked up from porn sites after Sales is done with the yearly trade show. You don't seem to know anything about storage or databases, at least.

    (Yawn). You know what you remind me of? A fleamarket chinese haggler who goes to a merchant and offer $2 for a flat screen tv. When the seller refuse, they offer again $2. And again and again and again they just make the same offer, slightly changing the wording and slowly raising their voice but always ending up with the same $2 amount. And when the seller has enough and ask them to go away, the haggler says, all mad: "why, you no bargain? $2 for the tv, good money".



    Also a side effect of you being a little whiny bitch is that because of your endless bitching, whatever insult you come up with ends up being just about the same as the previous ones. I've seen perl scripts that do a better job than you at trolling.

    Congratulations on yet again refusing to accept that you lost an argument. You can keep on making attacks that make no sense, or you can shut the fuck up and move the fuck on.

    I'm guessing you'll take the first option.

    Typical Bendover Ben. For the record there was no argument, Morbius just kept rehashing the same simplistic wrong understanding of how databases work. By now you should be aware of his copy-paste-contradict tactics, but don't let that come in the way of you high school crush on him.

    If you chalk this up as "Ben set up a trap and won an argument" I think it's because your mom over-congratulated you as a toddler for just about anything you did. That's typical of today's youth.



    Maybe some day you'll go to college and learn about rhetoric and sophism. In the meantime keep high-fiving yourself as nobody else will.

    I admit I don't know enough about databases to know whether Ronald or Morbs is right, but Morbs definitely scores the style points. Given Ronald's posting history, I think the odds probably favor Morbs on the substance, too.

    The weird thing is just how off in the weeds Ronald is on this one. "Databases don't sync things to disk when you commit!" Huh? I mean, it's a feature you can disable, if you don't care about your data, but having a commit actually commit to disk is pretty much a basic feature of how a database works. It's like the third thing you learn about databases after "Turn it on".

    "Oh, but if you sync every transaction, you will generate too much I/O! Databases can't handle lots of I/O!" Well, admittedly, the transaction log is the part of database storage that's harder to scale. Although, high-end equipment does come with things like write caches which are either non-volatile in nature (rare, but starting to creep in and will probably be more common over the next 5 years) or which are backed by an on-board battery. This means the writes are essentially just to high-speed memory, then it's up to the controller to make sure the data ends up on the actual disks.

    Anyway, this is all very basic. I'm still interested in what databases Ronald has used which apparently give no guarantee of transactions actually being recorded, thus making transactions kind of fucking pointless. I'm also interested in what "enterprise" storage he's used which doesn't have write caches and which apparently has IOPS in the high two digits..

    For example, put the database on a big SAN and then take periodic snapshots. You can restore one of those in a hurry since it's all online and copy-on-write.
    Our SAN has gone down a couple of times (and it's not exactly like we bought the system from the DPRK). We're past the stage of cynical jokes; joking about the SAN is a bit like joking about a recently deceased family member (i.e. you'll get some nasty looks).

     



  • @snoofle said:

    re the 70+TB: it's not just one customer info table; it was a set of very Very VERY large tables, and no, there isn't a way to just pick out individual records from a backup; they need to restore it by table, then pick out what they need from the temp restored table back into the main table. Effectively, they need to restore the whole database just to retrieve one customer's data. The really stupid part is they don't have enough space to restore the whole thing, so they have to do it one table at a time. The means that while the restore is going on,  some tables have sensible data and some don't. All while the system is live to customers (all of whom had to be informed that their queries would produce "interesting" results for a week or so until it could be straightened out). A total fiasco.
    The answer is probably going to be "no", but isn't there someone, somewhere high up, who figures that things aren't really working? That, at a certain point, keeping the mess you have (and from what I understand, the design of the database has quite a few issues) is a bigger liability than starting with a clean sheet and slowly migrate everything to there?

    All hardware breaks. The benefit of a SAN for the DR slave is the snapshots.

    Suppose that you are in the cafeteria and some moron from the helpdesk comes to your table and start talking about how source code is just zeroes and ones. You try to explain to him the basics but he just talk to you like you're some idiot. He then asks you to prove your point, ask what language is not made of zeroes, and all sorts of obviously off-target questions. If you answer him it's just going downhill as the insults make their way in the conversation, and then you have all the other helpdesk dudes taking sides as if it was election night.



    That's what is going on here. Morbius is talking out of his ass, but he's done it so often that he can't tell the difference anymore between what he knows and what he guesses, and he takes the fact that I don't reply to him anymore as a sign that he is right (which is not the case). And you have all the blind hitching their wagon to this idiot, like 13 years old sucking up to the black sheep uncle at Christmas dinner because he makes jokes about dildos and cum. Giggles giggles until they turn 20 and they figure out that he's a total loser.



    So you can think what you want, but the big difference between software and hardware is that there is a single version of the truth with hardware, and it won't get decided by a poll in a developers forum.

    Then by all means illuminate those of us who haven't insulted you or talked to you as an idiot.

    Except, of course, we were talking about database software and hardware. And your opinions on hardware are delightfully provincial, at the very least.

    Although I search for the database, there's nothing there for me to see.

    So I'm losing everything, 'cause the SAN has went down on me.

    A SAN is a complex ecosystem. When people say "SAN" they think about a big computer with lots of spindles, but the SAN part is actually the data network which sits between the servers and the disks subsystem. Often in the storage landscape there are multiple vendors involved, such as Emulex for the server adapters (HBAs), Cisco for the networking, Netapp for the dedup and nearline storage, IBM for storage virtualization and HP or Hitachi for the actual storage hardware, or any other mix. So what happens is that end users complain about having poor performance or having totally lost their volumes, and since there are no tools that can truly monitor end-to-end every specialist in the SA team says it's all green on his side; and they are not lying, often if you look at their screen you'll see that while end users are grinding their teeth with abysmal I/O performance the disks are barely spinning in the backend. It's like a highway that is very fluid and that for no obvious reason becomes jammed in the blink of an eye. Or a production line where people at one end are going nuts because of their workload while some other people are just reading newspapers, yet you cannot easily pinpoint where the bottleneck is. Or if you find it you can't find a way to resolve the situation without breaking something else.



    So at some point they bring in the vendors and of course the blame game starts. And if you pick a single vendor for the entire storage infrastructure (such as IBM), they basically re-brand products from other providers and when shit hits the fan they blame those. There is no way out.



    This being said, most storage admins I've met are very casual about the pain and suffering of end users; they get blamed all the time anyways so after a while they just ignore the noise and do whatever they want whenever they want. I call this the DMV Clerk Syndrome.
