Video fragments of my session posted at the end — read on.

I arrived at Omni Mandalay Hotel on Sunday evening with Dan Norris. I was flying through Chicago and it turned out that Dan was on the same flight and only few rows behind me. Small world.

Preparations for the conference were very chaotic on my part and, of course, I didn’t have either of my presentations ready. I was very stressed and getting sick as well — it looked like a complete disaster waiting to happen. I’d like to say that I was feeling like Doug Burns as he often managed to get sick just before a conference. Of course, I worked on my slides for the last few days as well as on the flight and presentation was slowly getting there but boy was …

As part of my upcoming FREE my.cnf check advice I first need to ask people to provide the current MySQL configuration file commonly found as a file named my.cnf

If only that question was easy to answer!

Use of configuration files

MySQL will by default use at least one configuration file from the following defaults. MySQL also uses a cascade approach for configuration files. When you have multiple files in the appropriate paths you can see unexpected behavior when you override certain values in different files.

You can however for example specify –no-defaults to use no configuration file, or add options to your command line execution, so even looking at all configuration files is no guarantee of your operating configuration.

However for most environments, these complexities do not exist.

Few weeks ago I was at FOSDEM.  It was really amazing experience. I meet many interesting people, learned quite some thing and I returned full of enthusiasm. Open Source events are really great.

But all the fun wasn't over even after the FOSDEM. I spent few more days in Bruxelles attending MySQL packagers meeting organized by SUN/Oracle. We spent quite some time talking to each other. We learned what MySQL people are doing and how. And they learned how do we deal with MySQL and what is troubling us. And many good things will come from this.

First but certainly not last of them is about to appear now. One very interesting thing we learned at meeting was MySQL release policy. What openSUSE and Ubuntu and maybe some others are doing is that after release date there is generaly no version updates allowed. We are only fixing serious bugs and security related …

Data comparison is a difficult and resource-intensive process. For convenience, this process can be divided into several steps.
First, you should compare tables from one database on one server with the database on the other server. You should choose columns for data comparison, and also choose a column that will be a comparison key.
The next step is to choose all data from these tables or some specified part of the data.
The third and the most important step is comparison of the two tables by the selected comparison key itself. During this process the status of each record is set to “only in source”, “only in target”, “different”, or “equal”.
The final steps of the data comparison process are including records to the synchronization and synchronization itself. During these steps records needed for synchronization are chosen, update script is created, and after that the script is executed.

Changes (as compared to 8.22) include:

Features:
* Added an option to define a ‘color code’ for a connection. The color will be used as background color in the Object Browser.
* A Query Builder session can now be saved and resumed.
* In Query Builder a table alias can be defined for any table by double-clicking the title bar of the table symbol.
* In RESULT tab results can now be retrieved page-wise. This is ON as default with this build with a defined LIMIT of 1000 rows. For a specific query user can change and for this specific query the setting is persistent across sessions. Also read ‘miscellaneous’ paragraph below.
* Added a context menu to Query Builder canvas.

Bug Fixes:
* Deleting a user would leave non-global privileges orphaned in the ‘mysql’ database. Now we use DELETE USER syntax if server supports.
* Also using …

I'm happy to announce that my talk "Making MySQL administration a breeze - a look into a MySQL DBA's toolchest" has been accepted for this year's edition of the MySQL Conference & Expo in Santa Clara, which will take place on April 12-15, 2010. The session is currently scheduled for Wednesday 14th, 10:50 in Ballroom E.

My plan is to provide an overview over the most popular utilities and applications that a MySQL DBA should be aware of to make his life easier. The focus will be on Linux/Unix applications available under opensource licenses that ease tasks related to user administration, setting up and administering replication setups, performing backups and security audits.

Of course I will cover the usual …

At the 2010 O’Reilly MySQL Conference and Expo there will be a Drizzle BoF!

It’s currently scheduled for 7pm on April 13th.

Come along, it will be awesome.

After a good while (I can’t search my Twitter stream) on Chrome I’m switching back to Firefox as my primary browser, and actually uninstalled Chrome. Why? I was getting the “Oh snap” failure page all the time, even on Google’s own Youtube! The only support I was pointed to was this page, and when I followed the instructions there when I restarted Chrome everything was gone. The sentence “copy the relevant files from the “Backup User Data” folder to your new “User Data” folder.” is useless when you consider the folder has 50+ files to sort through and I wasn’t sure which one was causing my previous problems. So back to Firefox, and thanks to Xmarks all of my stuff is there. …
