Here it is finally: The MySQL conference 2012 starts with the Keynote Sessions.

The first keynote speech was by Peter Zaitsev, founder of Percona and a very smart guy, and by Baron Schwartz (Percona), another very smart guy, the brain behind a number of toolkits for MySQL. They’re talking about the MySQL Evolution – what I alluded to in my first post regarding this conference – the ways in which MySQL has grown, evolved, scaled and continues to make new inroads into new applications and industries.

From Peter: “What is most important hasn’t changed – MySQL is still a great piece of technology and it is evolving very rapidly.” (Love that quote!) Also “MySQL is also buzzword compatible: NoSQL, BigData.”

From Baron: He talked about his own personal journey from closed-source, proprietory to open-source, and the …

With all of the new news coming out right now, it can be easy to miss or overlook some of the new features.

While there’s been a lot of talk about MySQL 5.6 Replication, I specifically wanted to mention the new ‘mysqlfailover’ and ‘mysqlrpladmin’ utilities.

These are two new MySQL replication utilities (results of the new Global Transaction Identifiers (GTIDs) in MySQL 5.6).

Let me quote the MySQL 5.6 Replication article for both of these utilities:

mysqlfailover

“Provides continuous monitoring of the replication topology, enabling failover to a slave in the event of an outage on the master.

The default behavior is to promote the most up-to-date slave, based on …

It is that time of the year, again: Percona Live is the name of this years MySQL conference in the Santa Clara Hyatt Regency.

Booking.com is there, and we are hiring, looking specifically for Admins and DBAs, but we also have Developer positions open.

Meet Nicolai and Sheila at the booth, if you have any questions.

Whilst I am not a fan of Juniper Network Connect in the last few years I have had to connect to several networks that use it.  The biggest problem with it is that it is a combination of Java and a 32bit C library which will not work when executed with a 64bit version of Java.
There are other ways of connecting such as the Mad Scientist script but if you use things like two-factor authentication this will not work.  So I brought together things I have learnt from web postings about getting it to work in Ubuntu and have created these steps.  They work in Fedora 17 and should work in 16 too:
Step 1We need to install OpenJDK Java, we also need xterm for the root password during installation:

sudo yum install java-1.7.0-openjdk.i686 java-1.7.0-openjdk.x86_64 icedtea-web xterm

Step 2Now we need to tell Java to execute the Juniper …

I must admint I was greatly impressed by the Oracle activity on MySQL yesterday. I cannot say I didn’t see it was coming, but most certainly the magnitude of what happened, the flood of announcements, was a bit overwhelming. Looking at the list of improvements, I started wondering what can it actually mean to the MySQL ecosystem.

Several years ago MySQL was forked into several different projects driven by groups of passionates as well as commercial businesses. Many considered the pace of MySQL evolution to be insufficient, while some didn’t agree with the direction or was complaining on the quality.

These were not unfounded. Rather than on the software itself, MySQL AB was focusing more on preparing itself for public offering, which eventually didn’t happen. It sold out to Sun. However, instead of …

After introducing InnoDB persistent statistics in MySQL 5.6, in this April Labs release we have dressed it up in a nice UI and refactored the internals a bit to make the code more elegant and straight-forward.

The persistent stats are now controlled globally and can also be overridden at table level, should any table require a different behavior.

Global

The server global flag –innodb-stats-persistent (boolean) now controls whether all InnoDB tables use persistent statistics or not. Keep in mind that if a table is using persistent stats then its statistics will not be updated automatically and you are responsible for …

As MySQL continues to grow (as a technology and as an ecosystem) the need and importance of creating and deploying robust MySQL backup solutions grows as well. In many circles Zmanda is known as “The MySQL Backup Company”. While we provide backup of a wide variety of environments, we gladly take the label of backing up the most popular open source database in the world, especially as we kick off our presence at the 2012 MySQL Conference.

Here are some of the updates to our MySQL backup technologies that we are announcing at the conference:

Announcing Zmanda Recovery Manager 3.4

We have updated the popular Zmanda Recovery Manager (ZRM) for MySQL product for …

The server global flag –innodb-stats-persistent (boolean) now controls whether all InnoDB tables use persistent statistics or not. Keep in mind that if a table is using persistent stats then its statistics will not be updated automatically and you are responsible for running ANALYZE TABLE periodically, whenever you think the table contents has changed too much. Thus the default for –innodb-stats-persistent is currently set to OFF.

In this April MySQL Lab release, we’ll provide you a more robust and release-ready InnoDB Memcached Engine with a few enhancements. The most notable addition is the SASL support, which gives users the capability to protect their MySQL database from unauthenticated access through memcached clients. In this blog, I will walk you through steps of getting this option enabled.

Background Info:
SASL stands for “Simple Authentication and Security Layer”, which is a Standard for adding authentication support to connection-based protocols. Memcached added SASL support starting its 1.4.3 release. And here is a good article that gives you some background on why …
