This tutorial will show you how to install Dynimize. We'll then use it to optimize a live MySQL process that's been running the Sysbench OLTP benchmark, obtaining a 46% increase in performance by applying Dynimize.

Part 1:  Quickstart

Here's a quick overview of how to use Dynimize.

To install Dynimize, run the following commands.

wget https://dynimize.com/install -O install
wget https://dynimizecloud.com/install.sha256 -O install.sha256
sha256sum -c install.sha256; if [ $? -eq 0 ]; then sudo bash ./install -d; fi

I had an enjoyable time last night at Twitter with local MySQL DBAs and developers. We had an attendee who has no experience with SQL or programming at all. She is interested in organizing her collection of recipes and had heard a rumor that MySQL was a good tool to use for this task. She indicated that her desktop runs Windows 7. I think I’m going to encourage her to turn her concept in to a community project, as she is not the first person I’ve met who wants to organize recipes!

We were hosted by Rob at Twitter, who used to work with Lisa back before she retired. He’s a member of the site reliability team and keeps the fail whale from rearing its blubbery head.

Pizza was provided by my dear friend and long-time open source buddy Gerry Narvaja with the assistance of the folks in the kitchen at Zeek’s.

We discussed new techniques in the areas of load …

As many of you know, I’ve been working in the MySQL world for quite a while now. IN fact, it was nearly 10 years ago when I first started hacking on MySQL Cluster at MySQL AB.

Most recently, I was at Percona which was a wonderful journey where over my nearly three years there the company at least doubled in size, launched several new software products and greatly improved the quality and frequency of releases.

However the time has come for something completely different. The MySQL world is rather mature, the future of …

I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a local machine. Totally sweet.

When we were living at 6162 NE Middle in the nine-eight 292, we got an 80386 which ran Doom. Yeah, the original one, not the fancy new one with the double barrel shotgun, but it would probably run that one, too. It was also …

The brief outage was due to a scheduled move of the servers to a separate rack and subnet dedicated to our work with the Center for Information Assurance & Cybersecurity (ciac) at the University of Washington Bothell (uwb), and a11y.com

I am currently exercising the new (to us) equipment and hope to winnow the less than awesome equipment over the next quarter. I spent the last six months finding the best in breed of the surplussed DL385 and DL380 chassis we (work) were going to have recycled. The team and I were able to find enough equipment to bring up one of each with eight and six gigs of memory, respectively. These will make excellent hypervisors for provisioning embedded instances of Slackware, Fedora, RHEL, CentOS, Debian, FreeBSD, OpenSolaris, OpenIndiana, FreeDOS, etc.

When I initially configured this xen paravirt environment, I failed to plan for integration with libvirt, so I am now re-jiggering the software bridges so …

I have had most of my test environment, aka puppetmasters, test mysql setups etc running in KVM for the past couple of years .. (yes I`m still using a lot of Xen in production environments, but we've also been using KVM for a while already .. it's a good mix) , Virtual box has always been the lesser loved Virtualization platform , however while playing more and more with Vagrant Up I realized I needed to convirt some boxen (e.g my PuppetMaster) to Virtualbox, and google was really no good help(most people seem to go the other way , or want to use some proprietary tools )

So I remembered VBoxManage and apparently I hade blogged about it myselve already ..
I just hate it when I search for stuff and google points right back to me

So I converted my puppetmaster's disks

In the Autumn, I wrote about some experiments I did using KVM and virtual machines to build and test MariaDB binary packages on a number of different platforms. In the period since then I added some polish and refinements, and the system is now running well for some time. We build and test packages for Debian (4 and 5), Ubuntu (8.04 to 10.04), Centos 5, and generic Linux; amd64 and i386 architectures.

To better control the startup and shutdown of the virtual machines, I created a small wrapper script around KVM called runvm. This wrapper encapsulates the steps needed to boot up a virtual machine, run a series of commands inside it, and shut it down gracefully afterwards. Some special care is taken in the script to ensure that the …

Red Hat announcements round-up
Red Hat announced a whole heap of products and projects this week. They should have organized an event to coincide with all the announcements. Or something. The biggest news was probably the launch of Red Hat Enterprise Linux 5.4 including KVM and other virtualization capabilities, while Red Hat and HP partnered to optimize Red Hat Enterprise Virtualization for HP BladeSystem Matrix. The company also revealed that Red Hat Network Satellite …
