While Oracle deserves some praise for its donation of OpenOffice.org code to the Apache Foundation, it is disappointing again to see a legitimate open source market contender that has been marginalized by miscommunication and mismanagement of the project by a large vendor.

OpenOffice.org, warts and all, was probably the most significant competition for Microsoft Office for years and in many ways demonstrated the advantages of open source, helping usher in wider use of it, as well as greater usability. OO.o was in fact my reason for originally investigating and moving to open source software more than a decade ago. Regardless of past mismanagement of community and technology, that competitive factor has been diminished greatly since Oracle took ownership of OO.o. Now, after prompting a fork — as has …

One of the ‘things I wrote down during OSBC’ was this statement from Benchmark EIR, Rob Bearden:

“Misalignment between a business model and the community’s tolerance point will never be accepted. This will manifest itself in multiple distributions.”

At first glance the statement may seem obvious to anyone who has studied open source-related business strategies or communities, but I believe provides the context for further understanding the complexities of balancing the needs of a business for control and the needs of a community for openness.

As the following graphic demonstrates, the statement suggests that there is a window of opportunity within which the control point of the vendor, and the tolerance point of the community must be closely aligned:

I wrote this up a while ago and decided that I didn’t want to lose it in a shuffle of documents during my transition to a new workstation. It’s the basics of setting up Heartbeat (LVS) + DRBD (block replication between active/passive master servers) + MySQL. This should give you the basics of a H/A system without the benefits of SAN but also without the associated cost. The validity of this setup for H/A purposes is highly dependent on your workload and environment. You should know the ins and outs of your H/A solution before deciding to blame the system for not performing as expected. As with all production systems you should test, test, test and test some more before going live.

When I get around to it later I’ll post my How-To for setting up RHCS + SAN + MySQL. You can download the DRBD document PDF here: …

Quick update to the framework that was released yesterday; I’ve added automatic graph generation. I chose DyGraphs due to the quick ability to enable support – the HTML is very quick and simply loads the CSV data. It has the same zooming features of Highcharts without the JS overhead.

Now when you run a load test you will get (in the output directory) a mixture of files: the main cumulative CSV and HTML file for the hostname that was tested, and then one CSV and HTML per report variable that was tested. This means you don’t have to drag the main CSV file into an alternate program or spend time parsing out certain variables one at a time to generate specific graphs.  I’ve also added support for limiting output of SNMP variables (LOAD,CPU,MEM). Head over here and download the update: http://code.google.com/p/quadrant-framework/

It seems that everyone loves load testing these days. Problem is that everyone is using their own quick scripts, simple or complex, to drive their tests without the ability for other DBAs to duplicate those tests. Let’s say I write a great test and share my results and graphs on the blog – you want to run the same tests to see how your new DB servers compare in performance: this framework allows you to do that without duplicating any work or writing code. This is a basic release that will get the ball rolling. I’ve included some sample tests in the README file, so give them a try.

This codebase offers a user friendly framework for creating and visualizing MySQL database load test jobs. It is based around Sysbench, which is generally considered the industry standard load test application. The framework allows you to do the following:

• standardize your tests without requiring you to write one-off bash scripts to handle …

Two years ago I published a post entitled “things I wrote down during OSBC”. It tuned out to be surprisingly popular, so I decided to try the same formula again.

Just as was the case two years ago these are presented chronologically. I wrote down a lot more than this, to be clear, but these were the most quote-worthy things. Also, as in 2009, some of them confirm things we already think about commercial open source (or in some cases data management), others were interesting ways of expressing old ideas:

“The next generation of computing is being led by users, rather than vendors.”
Jim Whitehurst

“The value of open source has moved from commoditization to innovation.”
…

Next Monday, May 16, I will be hosting session at the Open Source Business Conference in San Francisco focused on NoSQL, NewSQL and Beyond.

The presentation covers our recently published report of the same name, and provides some additional context on the role of open source in driving innovation in distributed data management.

Specifically, the presentation looks at the evolving influence of open source in the database market and the context for the emergence of new database alternatives.

I’ll be walking through the six core drivers that have driven the development …
