Open Query blog

I was reading Colin Charles’ write-up of Does Open Source need to be “Organic”? (with Brian Aker, Rob Lanphier, Stephen O’Grady, Theodore Ts’o). I’ve been thinking about this a bit, and I’m going to put out a hypohesis here…. see what you think: I think that overall, dual licensing as a large scale business model [...]

This DBA course day is in part based on info from Peter Zaitsev‘s earlier explorations (thanks Peter), and of course new insights from the High Performance MySQL book (there’s a lot of Baron in there, all credit to his great work!), wisdom from Mark Callaghan, with my own teach approach and style thrown in to [...]

I scribbled some quick info and my own perspective on About Drizzle, with links to the various currently available resources. I think it’s an interesting and [...]

Related to my post earlier today about the use of MySQL 5.0 and the Open Query course on upgrading and new features… I thought it might be good to do a broader poll of the MySQL population and see what version people are using for development (not deployment) right now! Use this link to go [...]

But I still have many clients that are on MySQL 4.0 or 4.1 both in production and development. Works fine, overall, but quite a few problems would be nonexistent if they were [...]

Good idea: WhoCallsMe?. Tracks nuisance calls (globally), of course only if there’s a CallerID. Check on the site if the number is already in the system, read the comments, add your own. Simple, but useful.

my.cnf can take the open_files_limit=N option in the [mysqld_safe] block. This doesn’t do anything to mysqld directly, instead the mysqld_safe script calls ulimit -n <N> These days, we might want to limit mysqld to use a maximum of 4 cores (using taskset on Linux) so InnoDB performance doesn’t degrade. Of course this is only relevant [...]

Interesting comment spotted on Jonathan Schwartz’ blog: [...] I work for a major Fortune company, and we’re in the process of putting Oracle on a “sunset” list of restricted vendors. No new applications are allowed on Oracle, the only approved vendors are Sun/MySQL and Microsoft/SQL Server. So I don’t know how Sun did that, but [...]
