Oracle crosses the line on integrity :(

Dana Gardner did a puff interview with Oracle and HP regarding Exadata, and clearly disclosed sponsorship up top. So far, so good. My sponsored work is a lot more independent than that, but I’m probably an outlier at the other extreme. Gardner’s view of what’s ethical in this regard is a common one, and the point of this post isn’t to argue with his choices in that regard, nor of those who hired him.

Where things went badly awry is on an Oracle corporate blog, which said: Read more

Has there been any progress on SAP over Postgres?

Peter Eisentraut discouragingly reported in January:

What I hear from my acquaintances at SAP, however, is this:

  • SAP doesn’t need fancy database features, since the software doesn’t use them.
  • Those who don’t want to buy Oracle can use MaxDB; it’s free.
  • PostgreSQL doesn’t support in-place upgrades, which makes it unsuitable for multiple terabyte installations typically used by SAP customers.
  • Has anything changed since then?

    And as a trivia challenge, does anybody recognize my science fiction reference in the comment thread there? 🙂 Hint: The dialogue referenced did not occur on the planet Arrakis.

    Exadata and Oracle Database Machine parallelization clarified

    Some kind Oracle development managers have reached out and helped me better understand where Oracle does or doesn’t stand in query and analytic parallelization. This post supersedes prior discussions of the subject over the past week. Read more

    Oracle Database Machine performance and compression

    Greg Rahn was kind enough to recite in his blog what Oracle has disclosed about the first Exadata testers. I don’t track hardware model details, so I don’t know how the testers’ respective current hardware environments compare to that of the Oracle Database Machine.

    Each of the customers cited below received “half” an Oracle Database Machine. As I previously noted, an Oracle Database Machine holds either 14.0 or 46.2 terabytes of uncompressed data. This suggests the 220 TB customer listed below — LGR Telecommunications — got compression of a little under 10:1 for a CDR (Call Detail Record) database. By comparison, Vertica claims 8:1 compression on CDRs.

    Greg also writes of POS (Point Of Sale) data being used for the demo. If you do the arithmetic on the throughput figures (13.5 vs. a little over 3), compression was a little under 4.5:1. I don’t know what other vendors claim for POS compression.

    Here are the details Greg posted about the four most open Oracle Database Machine tests: Read more

    Oracle Exadata list pricing

    The figures in this post have now been updated.  There’s a new spreadsheet at that link as well.

    I’ve been trying to figure out how much Oracle Exadata actually costs. My first cut comes up with prices of $58-190K/TB (user data), based on a total system price of $5,322,000, and user data figures of 28 and 92.4 TB for the two available sizes of disk drive. But of course there are a lot of uncertainties in these figures. You can use this spreadsheet (Edit: That’s the old one) to see where the final numbers come from, and to modify the estimates as you see fit. Read more

    Oracle Exadata Smart Scan Join Processing

    Oracle has put up an Exadata white paper (hat tip to Kevin Closson’s Exadata FAQ). There’s a section on Smart Scan Join Processing. Sounds exciting, huh? It reads, in its entirety:

    Exadata performs joins between large tables and small lookup tables, a very common scenario for data warehouses with star schemas. This is implemented using Bloom Filters, which are a very efficient probabilistic method to determine whether a row is a member of the desired result set.

    Jeez. That almost sounds as if Exadata is an immature, Release 1 data warehouse appliance!

    So what does Oracle Exadata mean for HP Neoview?

    That HP is committed to selling a lot of data warehouse hardware — and probably data warehouse appliances in particular — seems obvious, for reasons including:

    But Oracle Exadata could produce those appliance sales. So where does HP Neoview fit in?

    I was told by an investor today that HP’s investor relations department is saying Oracle Exadata is a Netezza competitor, while Neoview is more in the Teradata market. That’s laughable. Read more
