Applying binary logs to a MySQL instance is not particularly difficult, using the mysqlbinlog command line utility. Turning off binary logging for a session is not difficult, from the MySQL commandline, if you authenticate as a user with the SUPER privilege.sometimes you want to apply binary logs to a MySQL instance, without having those changes applied to the binary logs themselves. One option is to restart the server binary logging disabled, and after the load is finished, restart the server with binary logging re-enabled. This is not always possible nor desirable, so there’s a better way, that works in at least versions 4.1 and up
Here’s the future of MySQL, Drizzle, Monty Program, the Percona fork, etc. The best product management strategies… should we be lightweight for the web, plug-in oriented like Drizzle? Should we follow Monty’s giant-killing roadmap? Should we focus on performance-oriented patches? The best product management strategies will win. They can’t win alone. Will they be backed by appropriate investments from effective developers? Effective developers are the ones who convert winning product management strategies into working products. You can’t get there without them and I’ve seen lots of great strategies fail that test (including my own actually). And there can be more than one winner.
For many, CPAN is a Canadian Prairies-sized field of modules where it’s darn hard to separate the wheat from the chaff. While the CPAN Ratings service is the principal and official way CPAN tries to rank its distributions, for me at least, it doesn’t quite scratch the itch. Consequently, for a while now I’ve been playing with ideas on how the rating could be improved. What I came up with so far is a very minimal system going straight for the goods. And now, since I’ve had a three-day week, I decided to give the idea a try and implement a prototype.
Today I’ve read the following email on the mailing list of Sydney Oracle Meetup. I thought that this question is asked many times in attempt to find a silver bullet to learning Oracle so I wanted to publish my reply here on the blog, especially, that I’m a firm believer in one silver bullet that exists — there are no silver bullets.
The “Beer” version of DBD::Oracle (1.24) has been released. You can find it at CPAN DBD::Oracle. DBD::Oracle is a Perl module that works with the DBI module to provide access to Oracle databases. It is maintained by me, John Scoles, under the auspices of Pythian as Open Source/Free Software. This is largely a maintenance release that fixes a number of bugs. New stuff includes some more improvements to embedded types from Charles Jardine. Find out more here.
This is the third post in Oracle GoldenGate Extract Internals series (links to part I and part II). In this post, we’re going to take a closer look at various queries that the Extract process uses against the database. As before, we will start by examining the strace output.
Want to contribute to your favorite CPAN module, or maybe create your own, but don’t have the foggiest idea how to do it? Here’s a few notes, tips, tricks and links that might help you get started.
The call for proposals for Birds of a feather sessions closes at 11:59 pm PST on Thursday, February 18th, 2010. Sessions can be added during the conference, but if you submit and your BoF is accepted it will be printed in the schedule.
Ronald Bradford’s recent warning to be sure to know your my.cnf sections reminded me of a similar issue that I ran into last summer, where putting the “group” option in both the [mysqld_safe] and [mysqld] directives resulted in a mostly silent problem. I started noticing this in MySQL 5.1 and it affected both the official MySQL binary and the Percona binary. In trying to be conscientious, I had the following set..
Half the time I want to peek at the doc of a module, I hit perldoc. The rest of the time I type cpan Some::Module[1] in Firefox and read the POD straight out of CPAN. And while it’s pretty and handy, it also feels kinda silly to go on a remote server to read documentation that is also sitting on my computer. Surely, I tell myself, there must be a better way. And here it is.
