Well, it took us a little while (we’ve been busy 
!), but we’ve now posted our presentations on InnoDB from the MySQL Conference and Expo 2009. You can download these presentations by Heikki Tuuri, Ken Jacobs and Calvin Sun from the InnoDB website, as follows:
Hi,
If by any chance you are at the MySQL user conference in Santa Clara conference center, there are some great possibilities to see MySQL and Solaris Cluster in action. We have a demo at the exhibition hall, where you can see MySQL with zone cluster and MySQL with SC Geographic Edition.
I will host a birds of a feather at Wednesday 4/22/09 evening in meeting room 205 at 7 pm. The Title is "Configuring MySQL in Open HA Cluster, an Easy Exercise" check out the details here. I will give a presentation at Thursday 4/23/09 morning 10:50 in Ballroom G, the title is "Solutions for High Availability and

While caring for a remarkable amount of MySQL server instances, troubleshooting becomes a common task. It might of interest for you which
Recovering a crashed MySQL server
After a server crash (meaning the system itself or just the MySQL daemon) corrupted table files are quite common. You’ll see this when checking the /var/log/syslog, as the MySQL daemon checks tables during its startup.
Apr 17 13:54:44 live1 mysqld[2613]: 090417 13:54:44 [ERROR] /usr/sbin/mysqld: Table './database1/table1' is marked as crashed and should be repaired
The MySQL daemon just told you that it found a broken
[Read more...]Sure, you've heard it before: [some company's logo] has a new MySQL backup tool that promises to solve all of your data recovery needs. The good news is most of these tools work pretty well. However, they tend to suffer from a similar set of limitations. Most require sophisticated infrastructures or complex setup and maintenance and can become a resource drain for some organizations. You're probably wondering, "Why can't someone build a fully automated MySQL backup solution that you can just turn on and forget?"
I am happy to say that the MySQL Developers at Sun are doing just that. In fact, a prototype will be demonstrated at the 2009 MySQL Users' Conference that will show the feasibility of a fully automated MySQL backup and recovery tool. It's being called the MySQL Time Machine and (with all due respect to all vendors with products of similar names) it allows you to

[Read more...]That should read “Talks, Talks, Talks” … There will be several presentations by InnoDB experts at the upcoming 2009 MySQL Conference and Expo. Whether you’re a newbie or an experienced DBA deeply familiar with InnoDB, you won’t want to miss these important talks about InnoDB:
InnoDB executes a lot of transactions for MySQL users. And users and technical experts in the InnoDB community exchange lots of information about InnoDB … transacting in ideas … all the time. A great opportunity to participate in some of these transactions is the upcoming MySQL Conference and Expo.
Does your InnoDB-based application need more transactions to execute more quickly and reliably? Come hear these noted speakers present information that can help you get the most out of InnoDB:
My MythTV store lives on an LVM volume that is spread over 2 disks, one of them is an external USB disk. So the cleaninglady seems to have touched a cable and after coming back from holiday I had a read-only filesystem that afer a remount had about 350Gb in lost+found with irrelevant filenames.
Even though I didn’t go to MySQL conf this year (really sad about this), this week is gonna be most active in the community so I decided to do some community stuff too 
Today I’ve released version 0.3 of our innodb recovery toolkit. Now it became much faster, stable and accurate. At this moment it is possible to recover almost any table from corrupted/deleted tablespace without so much effort as it was before. Here is a short changes list (since 0.1 announced here):
Slave_IO_Running and/or Slave_SQL_Running as No and there is some error about a failed query when you run "show slave status;" and no amount of effort to fix it is working. First DO NOT PANIC. It is broken, OK, tell yourself that and realise that trying to fix something when you are in a panicked state is only [Read more...]
I’m returned from my 1-week vacation today and want to say - I’ve never been so productive as I was there 
Blue ocean, hot sun and white sand really helped me to finish my work on the first release of one really awesome project.
Today I’m proud to announce our first public release of the Data Recovery Toolkit for InnoDB - set of tools for checking InnoDB tablespaces and recovering data from damaged tablespaces or from dropped/truncated InnoDB tables.
This release already has a pretty decent set of features:
Progress on High Performance MySQL, Second Edition is coming along nicely. You have probably noticed the lack of epic multi-part articles on this blog lately -- that's because I'm spending most of my spare time on the book. At this point, we have significant work done on some of the hardest chapters, like Schema Optimization and Query Optimization. I've been deep in the guts of those hard optimization chapters for a while now, so I decided to venture into lighter territory: Backup and Recovery, which is one of the few chapters we planned to "revise and expand" from the first edition, rather than completely writing from scratch. I'd love to hear your thoughts and wishes -- click through to the full article for more details on the chapter and how it's shaping up.
