SUN Microsystems just bought MySQL. I don’t know much about SUN internals, but I’m not sure how the company resolves being the primary developer of 2 differing DBMS’s. Since those are the top 2 open source DBMS’s (and there aren’t really any other ones out there, as I don’t count sqlite as a DBMS), there could be a real conflict of interest.
The latest release of DBD::Oracle is now ready and can be found at: CPAN DBD::Oracle. It is a Perl module that works with the DBI module to provide access to Oracle databases. It is maintained by me, John Scoles as open source/free software, under the auspices of The Pythian Group.
The release has been fully tested with the latest version of DBI (1.601). A list of the changes and/or fixes in this release are included.
At the November MySQL User Group, Patrick Galbraith ran into a problem where binlog-do-db was duplicated. It manifests itself like this…Well, it’s a bug. Patrick confirmed that upgrading fixed his bug. Unfortunately, this is an enterprise release. Even more sadly, http://www.dorsalsource.org does not have the source or binaries for the most recent Enterprise version, MySQL 5.0.54.
The 79th edition of Log Buffer, the weekly review of database blogs, has been published on H. TonguÃ§ Yilmaz Oracle Blog.
With this particular client, I ran a SHOW STATUS, waited 100 seconds, and ran it again. Handler_read_first jumped by about 53. So I wrote down in my notes: first in the index…every other second. Lots of table scans? As soon as I wrote it down I said, “That’s a haiku!” I counted syllables, and it works, but only if you pronounce “Every” with 3 syllables.
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.
I was blog-tagged by Doug Burns – in his post, I *hate* chain letters ….I hate them too, I literally never pass them on no matter what vile fate that condemns me to. But this one includes a chance to talk about myself without seeming too self-involved, and there wasn’t even a threat of eternal damnation if I don’t do it. So let’s proceed then! 8 things about me that aren’t common knowledge…
I try to do a decent job of advocating for caring about good backups and business continuity strategies in my 7 Deadly Habits article. But this one beats them all, have a look for yourself, it too funny.
The listing of Dynamic System Variables on the MySQL Reference Manual’s page is supposed to show those variables you can change on-the-fly. The link at the top of this post, links to the 4.1 version of the manual, just in case folks are thinking I’m using a newer manual version. Mind you, I have this problem with 5.0.45 as well as 4.1.20.
I’ve been told that using NOT EXISTS in (Oracle) SQL is a bad idea, and that a way to overcome this problem is to collect the non-matching rows with an OUTER JOIN. So I decided to check if it is true.
