"Alternate methods for finding problem query.": chapter 5 of "Methods for searching errors in SQL application" just published
Employee_Team +1 Vote Up -0Vote Down

Translation of chapter 5 which describes alternate methods for searching problem query just published. It starts like:



Chapter 5. Alternate methods for finding problem query.


I already wrote about using of general query log requires resources.
Part of the problem can be solved if use new feature of MySQL 5.1:
online logging which allows to turn general query log to on or to off
without stopping the MySQL server.


Unfortunately this doesn't always work: you can have old
version of MySQL server which has not such a feature, general query log
can contain very large amount of information, so you can just miss the
problem in thousands of correct queries, you can have some other own
reason.



But what to do if you can not use general query log?

Translation of Chapter 4. Miscellaneous. of "Methods for searching errors in SQL application" just published
Employee_Team +0 Vote Up -0Vote Down

This chapter starts as:



Chapter 4. Miscellaneous.


There are cases when wrong output is just symptom of wrong input made before.



For example, you start to receive wrong data at particular step of the
scenario. After analysis of the SELECT query (or queries) is clear what
queries are correct and return exactly same data which exists in the
table (or tables).



This means wrong data was inserted at the earlier step.



How to know when it happened?


Start from the step of the scenario which exists just before
step which does output, check every query as was described in earlier
chapters. If everything works correctly, examine earlier step, repeat
until you find the error.

MySQL University: Securich - Security Plugin for MySQL (rerun)

This Thursday (June 10th, 14:00 UTC), Darren Cassar will rerun his February 25 presentation of Securich - Security Plugin for MySQL. (Recording of the session failed in February; hopefully it will succeed this time.) According to Darren, the author of the plugin, Securich is an incredibly handy and versatile tool for managing user privileges on MySQL through the use of roles. It basically makes granting and revoking rights a piece of cake, not to mention added security it provides through password expiry and password history, the customization level it permits, the fact that it runs on any MySQL 5.0 or later and it's easily deployable on any official

Software patents are a bad legacy to leave behind
+0 Vote Up -2Vote Down

Glyn Moody has an interesting piece on Why Patents are Like Black Holes where he looks at the situation when a large patent holder goes bankrupt - or is about to. His point is that even if a company otherwise can go out of business cleanly, the patents often remain as a piece of "IPR" that can come back and haunt us like a zombie.

Also Matt Asay recently weighed in on the subject:

Jonathan Schwartz leaves Sun/Oracle

Tweet

I read in his blog Jonathan Schwartz is leaving Sun/Oracle.  Jonathan was the CEO, Sun Microsystems, Inc.

Jonathan has been the force at Sun driving open source.  His voice will not be heard at Oracle so I’m wondering if this will make a change in the way projects like MySQL, Open Solaris and Open Office will be managed.

Continuing the journey

A couple of months ago (December 1st for those playing along at home) it marked five years to the day that I started at MySQL AB (http://www.mysql.com) (now Sun, now Oracle). A good part of me is really surprised it was for that long and other parts surprised it wasn’t longer. Through MySQL and Sun, I met some pretty amazing people, worked with some really smart ones and formed really solid and awesome friendships. Of course, not everything was perfect (sometimes not even close), but we did have some fun.

Up until November 2008 (that’s 3 years and 11 months for those playing at home) I worked on MySQL Cluster (http://www.mysql.com/cluster). Still love the product and love how much better we’re making Drizzle so it’ll be the best SQL interface to NDB :)

MySQL University: MySQL Galera Multi-Master Replication

This Thursday (February 11th, 14:00 UTC), Seppo Jaakola & Alex Yurchenko will talk about MySQL Galera Multi-Master Replication. Galera provides synchronous multi-master replication and uses a certification-based replication method for replicating transaction write sets in a DBMS cluster. The replication method requires close co-operation with database transaction processing and DMBS must support a specific replication API to be compatible with Galera. Codership has integrated Galera replication in the InnoDB storage engine, and the resulting MySQL/Galera cluster product has been published as a production-ready GA release in December 2009.
