We have been using SHOW ENGINE INNODB MUTEX command for years. It shows us mutex and rw-lock information that could be useful during service troubleshooting in case of performance problems. As Morgan Tocker announced in his blog post the command will be removed from MySQL 5.7 and we have to use performance_schema to get that info.
The documentation of MySQL also says that most of the command output has been removed from 5.6 and that we can find similar info in performance_schema. It doesn’t show any examples of how to use performance_schema or what is the query we need to use from now on. It is also important to mention that 5.6 doesn’t show any warning about the feature being deprecated.
This is a short blog post to show how to configure performance_schema and get the info we need. Hoping it will end …[Read more]

I’ll be helping Morgan Tocker deliver the second half of his training course for MySQL Developers/DBAs in New York City in a few days (more Percona training). It was a snap decision at the last minute, but I’m hoping I’ll still get to meet some folks there. If we’ve corresponded over email or blog comments and you would like to get together, ping me in the comments here!
If you’re in the New York City area and you use MySQL, you should consider attending this course, too. Morgan knows his stuff and has written a good curriculum. Attendees give his courses excellent feedback, and the price is very reasonable. Oh, and I’ll be there too, did I mention that? You can pick my …[Read more]
Yesterday I attended CPOSC 2009. The conference was great. It was very well run, and I liked the sessions. I would definitely attend this conference again, and will recommend that Percona sponsor it next year. I attended the following talks:
- Stop Worrying and Start Monitoring with Nagios (Andrew Libby)
- DRBD, Network Raid, High Availability and General Awesomeness (Brian Gorka)
- MySQL Performance Tuning for non-DBAs (Tom Clark)
- Wonderful Desktop Tricks, and Aesthetics (Seth Jerome)
- Jump Start Django: The Web Framework for Perfectionists with Deadlines (Rob Yates)
- Watching and Manipulating Your Network Traffic (Josiah Ritchie)
And then of course I gave my own talk on Maatkit ( …[Read more]
Funding for Aptana and Jolicloud. Ingres targets MySQL. Trent Reznor on Open Core (sort of). And more.
# Aptana raised $7.8m in funding from Rembrandt Venture Partners and Accel Partners.
# Jolicloud raised $4.2m in series A funding for a Linux-based Netbook OS.
Not with a bang…
# Sun reported preliminary revenues for Q4 2009 of $2.58bn to $2.68bn, compared to $3.78bn a year ago.
Best of the rest
# Ingres …
Morgan has been with us for a while. Before joining Percona, Morgan worked as a Technical Instructor for MySQL (and then Sun Microsystems) in Canada where he taught courses on High Availability, Performance Tuning and Database …[Read more]
