MySQL University: Random Query Generator

This Thursday (December 11th), Philip Stoev will talk about the Random Query Generator, a new QA tool that generates pseudo-random queries targeted to exercise a specific part of the server being tested. It then executes those queries to check for crashes or assertions or to compare the results returned from two different servers (two versions, two different storage engines, optimizer flags, etc.). It is also able to execute queries against a replication master, constantly checking that the slave is okay and has not diverged.

Towards the end of the session, Philip will share his desktop and show some live examples. Make sure to adjust your volume in case the MySQL Server will utter agonized sounds.

Note that we'll be using a new session address / Dimdim URL:

http://webmeeting.dimdim.com/portal/JoinForm.action?confKey=mysqluniversity

You can bookmark this address, since it will remain valid for all future MySQL University sessions. Remember, though, that the meeting room will open only 15 minutes before the session starts.

Dimdim is the conferencing system we're using for MySQL University sessions. It provides integrated voice streaming, chat, whiteboard, session recording (slides and voice), and more. All you need to do to attend MySQL University sessions is point your browser to the address given above.

Philip's MySQL University session will start at 14:00 UTC / 8am CST (Central) / 9am EST (Eastern) / 14:00 GMT / 15:00 CET / 17:00 MDT (Moscow).

In January, we'll likely continue with a set of sessions on performance and scalabilty – straight from the Sun QA labs. Find the tentative 2009 schedule on the MySQL University home page.

MySQL University for up to 100 attendees

Yesterday (December 4th), Sergey Petrunia gave a presentation on what's new in MySQL Optimizer. Unfortunately, the slides didn't show up in the Dimdim presentation area, which also means that the recorded session only has Sergey's voice but not the slides. (I've filed a bug in Dimdim's issue tracker.) However, Sergey kept referring to slide numbers in his talk, so it should be fairly easy (just not as convenient as usual) to follow his recorded presentation.

The slides, together with links to the recording and the chat transcript, can be found on the MySQL University session page.

Next week (Thursday, December 11th), we'll use our brand new commercial Dimdim license to run the session. This includes a new session address / Dimdim URL:

http://webmeeting.dimdim.com/portal/JoinForm.action?confKey=mysqluniversity

You can bookmark this one; it will remain valid for all future sessions. Remember, though, that the meeting room will open only 15 minutes before sessions start.

Our new commercial license is for 100 seats, so everybody should be able to join future sessions. (For Sergey's session, we had between 15 and 20 participants. We were still using my free Dimdim account for that session, which limits the number of attendees to 20. I suspect some people couldn't join in. Sorry for that.)

Next week's session will be about the Random Query Generator, a tool that creates random queries that can be sent to the MySQL server. This MySQL University session will start at 14:00 UTC / 8am CST (Central) / 9am EST (Eastern) / 14:00 GMT / 15:00 CET / 17:00 MDT (Moscow).

MySQL Enterprise Monitor documentation public now

The MySQL Enterprise Monitor continuously monitors MySQL servers and alerts to potential problems before they impact the system. It helps eliminating security vulnerabilities, improves replication, optimizes performance, and more. Its newest feature, Quan (Query Analyzer), helps identify queries that could be tuned to improve performance. Quan enables database administrators to do the work that would otherwise require hours in just minutes, or even seconds, and it provides ongoing statistical information about the performance of your queries.

MySQL Enterprise Monitor is a commercial offering by Sun Microsystems, and so was the documentation. To help anyone (even if they're not customers) get a better and complete understanding of what exactly MySQL Enterprise Monitor is about and what it can do, we've decided to make its full documentation publicly available. This has been done now, and the docs are part of the MySQL Manual now; see: http://dev.mysql.com/doc/refman/5.1/en/mem-introduction.html

The MySQL Enterprise Monitor documentation is also part of of the manuals that cover MySQL 5.0 and 6.0.

About

mysqlf is a common typo on the #docs IRC channel of the MySQL documentation team. It shows a high (some might say, dangerous) degree of identification with MySQL. Trying to pronounce it will probably result in tongue injuries.
