Many of the DBA’s at Itchy Ninja Software, began their careers as PHP Programmers, or before… We remember times sitting in a small office together writing PHP code before there were even books on the subject! We were scouring the web looking for examples and such and relying heavy on the documentation at the php.net site!

We wrote custom shopping carts before the days of oscommerce, zencart, and such. We wrote code to interface with payment gateways and process credit cards live. We also wrote code to pull products from MySQL databases, show staff members, and such. We worked for a newspaper group and were writing news “engines” to pull the articles, archive data, etc.

Why am I reminiscing about all of that? Well, because frankly, we have been there. We know a lot of other developers are still there doing the kind of work that we began with. We know that we can help others not to make the same mistakes we have seen some of …

In the recently released TokuDB 7.5.5 the implementation of TokuDB hot-backup moved from a patch to the MySQL Server, to MySQL Plugin.  Why did we make this change?

TokuDB hot backup makes a transactionally consistent copy of the TokuDB files while applications continue to read and write these files.  Christian Rober wrote a nice series of blogs about how hot backup works.  See TokuDB hot backup 1 and TokuDB hot backup 2 for details.  In summary, the TokuDB hot backup library intercepts system calls that write files and duplicates the writes on backup files. It does this while copying files to the backup directory.

There are two changes made to MySQL to get TokuDB hot backup working.

First, the hot backup …

Good,, it’s very helpfully

This is a must see for anyone in the ever-transforming technology industry. Join Adrian Cockcroft, Jason Dixon, Nathen Harvey and Baron Schwartz discuss the Internet of Things. Some highlights:

• How do we reconcile the containerization dissonance?

• What are the advantages, scaling hurdles and security implications of Docker?

• What monitoring methods will ultimately reign supreme, and what tools are ahead of the curve?

• What are the paths toward DevOps, and will everyone eventually adapt?

• How do companies like Chef, Librato and NetFlix use containerization, monitoring and DevOps?

Hi,
Sorry for not replying sooner. I’m afraid MEB 3.10 has to be downloaded via support.oracle.com, as part of the Enterprise Edition. If you can’t find it (under Patches) just open an SR and support can help you locate it.

Thx for reading.

At FromDual, we are currently preparing for our participation in the "Chemnitzer Linux-Tage" in March.
While we don't yet know whether the programme committee accepted our proposed talks, we will have a booth and hope for interesting exchanges with others from the MySQL, database, Linux, ... world. Of course, we will also mention that we are looking for additional colleagues - there are so many tasks that we need more people to handle them all. (In case you got curious, look here: http://www.fromdual.com/mysql-dba-2014-12-de )

While I attended the Chemnitzer Linux-Tage already last year (thank you, Frank Hofmann, for recommending them!), it will be the first time there for FromDual as a company. I enjoyed the informal atmosphere, which made it easy to get into contact with new people, to learn, and to discuss both facts and opinions.

To those of you who …
