    Because they don't take context or purpose into account at all. There are things that Postress may be better for and things that Oracle certainly shines at. I mean, hell, I love MySQL, too, but I wouldn't want to use it as the backend for _my_ system. Not that the others are hollisticaly "bad", it's just that Oracle is the most appropriate for this situation.

    What's a TLD doing with a database? Making ridiculous numbers of extremely lightweight queries, and managing redundancy. That's not necessarily the same thing that everybody wants an "enterprise class" "tested" database to do for "mission critical" tasks.
    • Actually, this is a good question. What is the database used for? Profile information for WHOIS searches? That would make the most sense, and isn't *that* big a deal. A database to handle name resolution is a bit of overkill I think.

      And not to distract that yes it's good to see PostgreSQL getting some mainstream fame.

        Actually, this is a good question. What is the database used for?

        The database is a buffer between the requests comming in from the registrars and the DNS resolvers. So you get a bunch of requests comming in once a day saying stuff like 'change asm.org DNS to 10.2.3.243' and the registry has to decide what to do with them. To do that they need to have a bunch of info stating what registrar owns the account at the time and so on. And yes it is not unknown for registrars to attempt to do things they should not.

        The DNS infrastructure that is queried by you DNS server is completely separate. Every hour or so the SQL database will do a dump which will then be checked and if it passes will be sent to the production DNS infrastructure which is essentially a read only affair.

        So no, this does not mean that every DNS lookup in .org is going to result in a mySQL transaction. Nor can you say anything about whether this deployment proves mySQL is ready for primetime, at least not yet you can't. You probably want to wait to see how the zone holds up over the next few months before drawing any judgements.

        BTW the technical name for Oracle features is 'complications'.

      I don't think the issue is that PostgreSQL will crunch data as well as Oracle. It's just that PostgreSQL has always had an undeserved reputation as "the database to use when you can't afford a REAL database", when actually it's a very robust and secure system that can compete quite well with commercial systems.

      I'd really like to see some serious tests done with PostgreSQL. Database systems, especially Oracle, can be an expensive part of a datacenter. Considering that with Linux/PostgreSQL your only cost is hardware/support, it may very well scale more cost effectively than Oracle.

      There's currently way too much marketing and FUD to get a real idea how these systems compare though.

        I love PostgreSQL, have used it in a small (million-record) transactional application with great success, and am pleased to see the implied advocacy of having .org run on it. Nonetheless 2.4 million records is hardly enterprise-level stress. I would really like to see some serious benchmarks against Oracle. My tests on a small PC-based Linux server last year showed that pg beat Oracle mainly because the bloat of Oracle caused excessive thrashing, but on a large mainframe-type application - billion-record type stuff - I simply have no idea. A couple of years ago some benchmarks were published on the web but got quickly taken down by Oracle under threat of lawsuit - their license doesn't allow publication of benchmarks - and I never got to see them. I think this is wrong. Perhaps the recent ruling against EDA benchmark restrictions [eedesign.com] will open a door towards Oracle benchmarks?

        Competency isnt the issue here. I am assuming that whoever the actual developer of the fix is, that they will be extremely competent in fixing the problem. With an external entity, contractual terms of delivery will twist their arms into fixing severity 1 problems with the urgency that they deserve regardless of whether the fix is the best possible coding / architectural solution for the overall Postgres project. With an internal entity, the pressure will be less on them because if management threatens to "chop the head off" because of trying to do the "right thing" instead of just fixing the problem, they will have to stop and consider that they are damaging their own organization. It is always easier for management to be brutal with external entities rather than one of their own.

If indeed you find yourself dealing with employees who let the world collapse around them while they fritter away their time on trivia, they should, in fact, have their heads chopped off. But personally, I know precious few people who would behave in such a manner.

      Worse than that, it took several months for the Oracle support people to actually find out what had happened to FORTRAN.

      You are retrieving data from a 10 million row table using a very complex query and you are having performance problems? Who would have thought that?

      Normally I get paid a lot of money to solve problems like this but I'll give you a little guidance for free since you didn't like Oracle's answer.

      1) Maybe you should think about optimizing your query a bit. Running complex queries against 10+ rows can be problematic even when the RDMS has a good optimizer. Is there a less complex way to accomplish the same thing? If not, you may have to give the optimizer hints. Can you use an index to pull a smaller dataset into a working table where you do your complex operations?

      2) Profile your system to determine where the bottleneck is to be found. Is it CPU bound or IO bound. If it's IO bound, would more memory help? Can your tablespace be spread across more disks? Would a beefier system be appropriate? Cost Effective?

      This is why you hire qualified developers and administrators. I'm not surprised the tech team gave you that answer. You call the tech team when there is a real problem with the software. If you were paying Oracle to develop the database for you, you might have a case. But then, if that were true, you wouldn't have called tech support, would you?

        Oracle dropped the ball here. First, because the database *crashed* on the query. If you're telling me that *any* query I run should be able to outright *crash* the database then go work for Microsoft on MS-SQL. Worst case, the database should thrash incessantly (and accept a kill) or consume too much RAM and kill itself off, but certainly not HANG. I can't believe you suggest that's the fault of the person running the query and not the developer.

        But secondly, and most importantly, Oracle should definately offer tips on what to do. I mean, regardless of the situation, the thing ran, and *died*. Not slow. Not exceeding resources. Died. If it's a bug, fine. Then you offer a bloody workaround, *especially* if you have no intention of fixing the bug!

      Yes, you are wrong, as of PostgreSQL 7.2 VACUUM can run without locking the table completely.

      Garbage collection is a problem every database faces. Due to ACID requirements it is pretty much (absolutely?) impossible to run a database that updates rows without having multiple versions of the same row on disk at some time during the operation. So at some point in time you have to get rid of that duplicate. You can choose to do that after commit of a transaction (or the last transaction for which the row is still visible), but that would potentially make every transaction slower. So in PostgreSQL the choice was made to do this at an administrator determined moment (and I presume that choice also was the easy one).
      In older versions of PostgreSQL VACUUM would lock the entire table and physically force all the valid rows to be rewritten consecutively and then reclaim the space at the end. This mode is still available as VACUUM FULL, but nowadays there is a new mode (sometimes called lazy vacuum) that only marks space safe to be overwritten. Subsequent updates/inserts will overwrite it eventually.
      Regular running of this command will eventually lead to some steady state where there is some x% of bloat in the table, but there is no significant amount of locking required.
    • You don't stop PostgreSQL server to run vacuum in 7.x versions - you can do it in background.

      What you'll really missed in PostgreSQL for 24/7 is a good replication. But they are working on it.

      By the way, are you sure you want 24/7/365? I think 24/7/52 will be more correct, no? I don't think that 7 years of uptime is a good idea when you want to upgrade your software (usually you stop/restart the service for it) about ever year.

      • MySQL has a commercial entity backing it, that actually makes money selling commercial MySQL licences (the MySQL licence terms are kind of weird, "fully-viral GPL unless you pay us $$$"). This seems to have resulted in some marketoid-speak, which is unusual in the context of an open-source project. For example, "MySQL now supports transactions!" and various other "features", ignoring how fundamental such things are to a real RDBMS and should have always been a part of the design.
      • There are lots of people who don't understand why you would need "subselects" or "outer joins", and didn't know about "transactions" until they read about it in the mysql change log. And MySQL will be a real RDBMS Real Soon Now (tm) so there's no need to switch to anything else and besides you don't really need a real RDBMS anyway.
      • MySQL has a nice Windows installer.
      • PostgreSQL used to suck, once upon a time.

    ...that the entire O'Reilly Practical PostgreSQL book [commandprompt.com] was put online?

    I've spent so much time lately in the (relatively) flat-table world of MySQL that I had forgotten about inherited tables, subselects, constraints in table definitions, and oh yes, vacuuming. ;) Looks like it is time to revisit postgres, especially for some db-agnostic PEAR apps I'm building. For me, it's the subselects that really make it worth the effort.
  • Oracle, as most commercial DBMSs, doesn't let you export the database in SQL format. Of course, you can write scripts to do that, but it shows how the commercial companies are always trying to find ways to lock you in.
    • No shit? Is there an SQL dump feature for MS SQL ? I need to convert one to postgreSQL soon.
    • Of course it doesn't. SQL isn't a format. It's a "Structured Query Language". I don't even know what you're trying to do.

      As far as exporting, of course you can export. You can export whatever you want in virtually any format you want, and have been since, well, for as long as I remember. Ask a DBA.

      As far as I know, there has never been any regulation as to who can and can't register a .org domain. The association with not-for-profits is a convention, not a rule. Same with .net, which initially was for ISPs and other network service providers.

      Nowadays, .org and .net are largely used by registrants who couldn't get the .com they wanted. (On the other hand, I have two .org domains registered for legitimate non-profits, a town band and a cat shelter.)

    Will someone please tell me how the hell to pronounce PostgreSQL?

    Or are we supposed to pronounce it POST-GRE-SEE-KWEL? Or POST-GRES-CUE-ELL? Or POST-GRES-QUERY LANGUAGE?

    And where the hell did that name come from? Did they take "Ingres", and increment it (like how C became C++), thereby making it "Postgres"? Then "PostgreSQL" means "the better-than-Ingres query language"?

    I hate it when techies come up with names. It always ends up being something that's either stupid and meaningless, like C#, or self-referential and too-cute-by-half, like GNU. Recursive acronym my ass.

    "untested in mission-critical applications"?

    You'd have to be a completely ignorant moron to believe that. A good number of large companies have been running PostgreSQL succesfully in mission-critical situation for *years*.

    It's been used in network-monitoring apps for deployment in military vehicles, $30 million POS systems, medical systems, ticketmaster, a good number of heavy-traffic web sites, and just about everything else you can think of.

    Anybody who told you it hadn't been tested was living long in the past.

    I run a text-chat site that is -- please don't lynch me -- based on Win2K and MS SQL Server. The site does about 10-12 DB transactions a second on a slow day and about 100-150/sec on a fast day. At peak hours we have something like 30% CPU usage on the average (it's a 700 Mhz box, not bleeding-edge).

    A friend of mine put someone in touch with me who was trying to build a vaguely similar system and was having no end of problems. Transactions were timing out left and right, and his machine was more than twice as fast as mine. From his experiences -- and from what I've seen in a lot of parallel setups -- there is a difference between being able to code something functional and being able to code something that functions intelligently. I'd learned a lot of ways to cut down massively on system overhead -- use stored procedures, turn off locks when they're not required, don't use transactions unless they're absolutely needed, etc., etc. -- and all of them add up and pay off.

    As far as PostgreSQL goes, it's probably going to depend on how good a job they do coding it into their system. If they do it well, I'd imagine PostgreSQL is gonna be quite solid. If they do it like idiots, not even the best database solution in the world -- not Oracle, nothing -- is going to save them.

    Heck, even Oracle is going to break if you try to fetch a billion rows at once; the trick is to find smarter ways to partition and subdivide the data, to cut down the amount of time needed for every little step on the way. (I found out that adding ONE index in my system sped things up by about 30% alone, an index I would not have realized I needed until I ran a performance profile.)

    Let's see how well they do before we sling tomatoes, OK?

  • Postgres mission critical? Heard of VACUUM? (Score:3, Informative)

    We have been using and recommending postgres for our telephony server. Recently we had to test high load conditions involving lots of writes into a database with hundred thousand subscriber profiles. The database would slow down to rates of ten transactions per second after a day. When we dumped the database and restored it, it would start working fine again. We then found out that the postgres DB has to be "vacuumed" often to maintain performance levels if there are too many inserts and updates into the DB. We repeated our tests with a scheduled vacuum every hour. Here again the system was unusable during the vacuum run. With a mission critical DB I wouldn't expect such issues. There are also no clear guidelines available on how often a VACUUM has to be performed. This is not a rant against postgres. I appreciate the good work being done and I know that the postgres folks are working on this problem.

    With Oracle we haven't run into such problems. We do have other problems with the OCI that we use though. We find lots of uninitialized memory reads and leaks during connection recovery and technical support for the OCI libraries is real bad. No support issues with postgres.
