Everyone seems to have an opinion about whether Oracle should be allowed to acquire the MySQL database along with Sun Microsystems including former MySQL/Sun executives, developers, rivals, partners, analysts, journalists, the Department of Justice and even US Senators. What do open source software users think?

We asked the members of the “CAOS user community”* to tell what they thought of the proposed deal, as well as share some details on current database usage. The results have been published in the form of a 451 Group report (subscribers only) but here’s some of the headline figures:

• The use of MySQL is expected to decline from 82.1% of the 347 respondents today as 78.7% expect to be using it in 2011, declining to 72.3% 2014.

• The proposed acquisition of MySQL by Oracle has a part to play in …

As most of MySQL users, I have often ignored what I'd like to call the minor storage engines. MYISAM, InnoDB and NDB (aka MySQL Cluster) are well covered in several articles; but what about engines like CSV or ARCHIVE? As part of some internal projects, we have been playing around with these 2 with some interesting results. On this article I'll concentrate on CSV.
ScenarioCurrently we have a few servers that are storing historical data that will eventually be migrated into Oracle. Two things need to happen until we can finally decommission them: 1) export the data to CSV so it can be imported in bulk into Oracle and 2) keep the data online so it can be queried as needed until the migration is finalized. I thought it would be interesting if we could solve both issues simultaneously and decided to try the CSV engine. Here's a description of the process.
Understanding CSV EngineThe CSV engine, as far as I can tell, was and example …

I’ve been trying to dig a bit deeper into the European Commission’s investigation of Oracle’s proposed acquisition of Sun Microsystems, to look beyond the received wisdom about the EC’s concerns about the deal.

We know they revolve around the open source MySQL database, the European Commission has said that much. But the Statement of Objections weighs in at 155 pages, and even those that have read it admit to being confused by it. Meanwhile some of the most vocal parties in the public debate have vested interests in encouraging opinions for or against the deal.

Without knowing precisely what the European Commission wants to achieve it is impossible to come to any conclusions about the investigation. However, here are a few statements and observations:

I really like ZRM for MySQL Community Edition for backups. I find
it very simple to install and configure and it gets the job done. It's default settings suits most installations. The challenges arise once you need to adapt it to more complex organizations. Please note that all the issues described on this article refer to Linux installations.
What If DBAs Have No sudo?This was the 1st challenge that I ever faced. ZRM requires full root access at least during installation and in some cases, it requires some sudo permissions to be able to manage its files as well. Some organizations don't grant these permissions to the DBAs complicating the installation. When I looked into the scripts, I didn't see any reason why they wouldn't run in the user space, other than a few hard coded paths. I posted the question in the Zmanda forums and I got an answer with some …

A number of people have recently raised the issue of the threat that cloud computing poses to the monetization of open source by specialist vendors, including Savio Rodrigues, Matt Asay, and Mike Hogan.

I believe that cloud computing provides an opportunity for open source specialists, but agree that cloud services based on open source code could potentially eat into the business opportunities for open source specialists since the cloud providers have no …

Savio Rodrigues has published a post arguing that cloud platforms such as Amazon Web Services and Microsoft’s Azure pose a threat to the monetization of open source by specialist vendors.

Savio makes a good case based on the recent launch of AWS’s Relational Database Service, based on MySQL, and Microsoft’s support for MySQL and Tomcat on Azure:

“When Amazon decided to offer MySQL via Amazon RDS, they did so without purchasing MySQL support from Sun. I’ve confirmed that Microsoft Azure is supporting MySQL on Azure without paying Sun for a MySQL Enterprise subscription.”

Clearly there is a threat to open source vendors from cloud-based services. Meanwhile I have previous …

I am working with a client that is using managed hosting on dedicated servers. This has presented new challenges in obtaining the right permissions to undertake MySQL tasks but not have either ‘root’ or ‘mysql’ access and not have to involve a third party everytime.

Adding the following to the /etc/sudoers file enabled the ability to restart MySQL.

User_Alias      DBA = rbradfor, user2, etc
Host_Alias      DB_SERVERS = server1.example.com, server2.example.com, etc
Cmnd_Alias      MYSQL = /etc/init.d/mysqld, /usr/sbin/tcpdump

DBA DB_SERVERS = MYSQL

As you can see I also got tcpdump, which I find valuable to monitor via mk-query-digest.

Next, permissions for log files.
