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.

Since the European Commission announced it was opening an in-depth investigation into the proposed takeover of Sun Microsystems by Oracle with a focus on MySQL there has been no shortage of opinion written about Oracle’s impending ownership of MySQL and its impact on MySQL users and commercial partners, as well as MySQL’s business model, dual licensing and the GPL.

In order to try and bring some order to the conversation, we have brought together some of the most referenced blog posts and news stories in chronological order.

Part one took us from the announcement of the EC’s in-depth investigation up to the eve of the communication of the EC’s Statement of Objections.

Part two, below, takes us from there to the eve of the announcement of Oracle’s concessions. …
