Although many electrons have been expended discussing Exadata’s features, storage indexes tend to figure last, with a vague mention of row elimination in heavily clustered data. Even Oracle’s Exadata software user guide devotes barely half a page to them. Unlike the better known smart scanning features though, storage indexes have an important advantage: rather than offloading workload to storage cells, they eliminate the need to do the I/O at all. Here are some sample statistics taken from an actual production system:
In this series of articles (part 2 here and part 3 here), we’ll explore the major components of Exadata and the Oracle Database Machine and take a peek at how they’re designed with performance and scalability in mind.
Oracle has just released their January installment of their critical patch update (CPU). Vulnerability CVE-2010-0071 is particularly critical, with a CVSS score of 10, the highest possible. It’s a remotely-exploitable listener vulnerability that’s particularly severe on Windows platforms. Full details are on Oracle’s security site.
I was reviewing Oracle’s Processor Core Factor Table, which lists the multiplier used to calculate the Oracle Enterprise Edition CPU license requirements, and noticed something interesting: the preferential 0.5 core multiplier that formerly applied to all Intel/AMD chips has now been restricted to…
The latest quarterly update came out this morning. There are oh-my-god smoking guns this time, but several medium-important patches. If you’re running Oracle Collaboration Suite, note that the patch blows away the login and logout pages (oops!). MetaLink note 445172.1 has info on how to restore the pages post-patch.
It’s yet again time for Oracle’s critical patch update (CPUJAN2008). The update will be released on Tuesday January 15, and as of yet there are no details on exactly what vulnerabilities have been found.
With Oracle SE/SEOne, you can really stretch your Oracle licensing dollar: an 8-way box with a pair of quad-core processors can be licensed with SEOne (in the US) for $10k, and $2k/year for support (sold on a per-chip basis too). Now imagine running it on an 80-core chip!
The 11g platforms are now coming out fast and furious, In addition to the previously-released platforms.So download away, after checking your platform certification first, of course. Links to platforms in this post.
Hot on the heels of the Linux 64-bit release, Oracle 11g for Windows (32-bit only for now) is now available for download on OTN.
It looks like the second public platform release for Oracle 11g is (surprise, surprise) Linux x86-64. Downloads are available on OTN.
