Red Hat’s organic growth opportunities
+0 Vote Up -0Vote Down

We reported recently on Red Hat’s revenue growth and deferred revenue. One of the things I have been looking at recently is the slowdown in Red Hat’s growth in recent years, and the opportunities that the company has to improve that growth.

For some perspective it is worth noting that while Red Hat’s revenue has been growing steadily:

The rate of growth has been in decline for some time:

Microsoft has announced that it is to contribute code to the Linux kernel development effort under the GNU General Public License (GPL) v2. What on earth does it all mean? Here’s our take on the situation. With thanks to Jay Lyman for his contribution to the following:

Q. This is a joke, right?

Dear Oracle,
+1 Vote Up -0Vote Down

A couple of weeks ago I wrote a post titled Dear IBM , I was too late .. I was on holliday last week when people started sending me text messages , such as .. "Game Over MySQL , Long live Ingress" or "No Eclipse for IBM", etc ...

I had ideas regarding the future of certain Sun products at IBM, now the game has changed .. it'ss how they will live on at Oracle :)

Similar Questions arise .. like indeed the future of MySQL, the future of Solaris etc ...

So regarding the future of MySQL , I don't worry at all, on the contrary ..
Oracle tried buying mysql before they already have Innodb .. they didn't kill it .. the MySQL offering is complementary to the Oracle offering, now they can tackle both markets.
And as already mentionned when writing my IBM letter ..


As for MySQL, Jeremey has some

MySQL Conf 2009 Preview: Scalability and HA Tutorial
+0 Vote Up -0Vote Down

Like most people, and with just over a week to go before the conference, I’m putting the finishing touchs on my various presentations.

First up for me, on Monday afternoon, is my tutorial: Scale Up, Scale Out, and High Availability: Solutions and Combinations.

What will be doing?

Very simply: Looking at every potential solution for maximum scalability and availability for your database environment.

If you are attending, be prepared to:

  • Expand your mind as we think about scaling up.
  • Expand your horizons as we think about scaling out.
  • Divide and conquer, as we think about high-availability.

We’re not not hands on in this session – but I will expect you to be brains on!

My Sessions at UC2009

I’m speaking at the User Conference this year, with a half-day tutorial and three further sessions. The running theme is performance, both in terms of the performance of your queries, and in terms of scaling up.

Scale Up, Scale Out, and High Availability: Solutions and Combinations

This is the big tutorial. It’s difficult to resolve what I’ll be talking about into a few sentences, but think about all of the different technologies available here - replication, partitions, sharding, DRBD, memcached - I’ll be talking about all of them, and more importantly combinations of the different solutions and where the potential performance gains and pitfalls are. I’ll also be using the opportunity to demonstrate some of the more obscure combinations that you can use to provide

XenServer 5 with OpenBSD
+0 Vote Up -0Vote Down

Here is my experience trying to run OpenBSD with XenServer 5 Enterprise.

  • XenServer console doesn’t function properly as it keeps overlaying text displayed previously or anything you have typed into the console. Makes it very difficult to read and see what you are doing. As well it appears numerpad with numlock on does not work either. The best work around is to SSH into OpenBSD.
  • Receiving the following error messages at boot up, “clock: unknown CMOS layout” and “rl0: watchdog timeout”. Yes the NIC is being detected as a Realteak 8139. If I check /var/run/dmesg.boot out of the two error messages I only see the “clock: unknown CMOS layout”. So I would assume the watchdog timeout

Virtualizing MySQL , are you stupid ?
+0 Vote Up -0Vote Down

or timebound ? or don't you have any load on your DB at all ?

I personally don't see many reasons to virtualize your database, apart from the , we plan to start small and scale out, or the we need it now and we don't have the hardware yet , putting your database on a virtual platform where you have to share resources with other virtual machines doesn't really sound like a tempting proposition to me. Small, almost idle databases , maybe. But enterprise production level databases no thnx.

Sheeri Cabral also mentions the above reasons .. and there also .. Enterprise Production use isn't listed.

Databases typically require a good amount of memory , and steady disk access.
So if you are in a production environment with a fairly loaded database, would you want a 4Gb machine with full direct memory

Virtualizing MySQL
+0 Vote Up -0Vote Down

I had so much to say in response to a recent post asking about virtualization from Jennifer Glore that I realized it was long enough to be a blog post.

It really depends on what you’re looking to do. Many companies don’t have the money and staff to have an in-house data center with proper power and network redundancy; others don’t want the depreciation associated with owning computer hardware (even if they leased space in a data center, they’d have to buy equipment to put in it).

Some reasons to virtualize:
1) you need a fresh machine and cannot wait to order a new one or re-purpose an older one.
2) your need for machines/services fluctuates (and again, re-purposing takes time). This need can be as broad

Sun xVM VirtualBox is released!
+0 Vote Up -0Vote Down

VirtualBox 1.6 is out. Note that now you can use Mac OS X and Solaris as a host platform. Naturally, having Mac OS X support excites me.

I tried installing a Ubuntu 8.04 server guest. Found a tiny issue - 64-bit guests aren’t supported yet :( So I pulled in the 32-bit ISO, and that installed just fine. Note that PAE support for guests exist now, and this is a good step in the right direction.

Sun’s building an OpenxVM community, which currently focus on xVM and xVM VirtualBox. It also harnesses technologies like Open Service Tag. All in all, I think a lot of MySQL users should be interested in virtualization, as there is a growing amount of hardware out there with many,

This article describes how to install the Drupal 6.2 CMS on MySQL (http://mysql.com/) 6.0, using the Falcon Storage Engine. The operating system is a default Ubuntu 8.04 "Hardy Heron" (x86) installation.

I will make a few assumptions here, in order to keep the instructions simple: a fresh OS install, no other MySQL databases or web services are running or have already been installed. Both MySQL and the web server are installed on the same host. You should be able to become root to install packages and to have access to the local file system and

After a month of intense public review by our community users and contributors, we have made the initial “official” release of the DRBD User’s Guide.

This does not only include helpful information about building, installing, and configuring DRBD, but also on DRBD integration with Xen and LVM, Heartbeat, and many other applications. MySQL users will find the example MySQL HA configurations for both Heartbeat R1 and Heartbeat CRM clusters particularly helpful.

MySQL Benchmark UltraSPARC T2 beats Xeon on Consolidation of OLTP & Web
Employee +0 Vote Up -0Vote Down
Recently we put together a consolidation benchmark to see how an open-source stack performs against the proprietary stack from Microsoft. Solaris, MySQL, and Sun Web Server running on the open-source UltraSPARC T2 processor were pitted against a Microsoft SW stack running on a 4-socket QC Xeon server. This benchmark highlights the continued trend to incorporate MySQL open-source databases and how it works under virtualization (Solaris Zones).

The Sun SPARC Enterprise T5220 (1.4 Ghz UltraSPARC T2 processor) and Solaris Containers managing a consolidation of Open-Source Software components (MySQL Database and Sun Java System Web Server) provided 2.4 times better performance than the HP DL580 system (four Xeon quad-core processors) and a major virtualization software, Microsoft Windows 2003 Server EE, Microsoft SQLserver database and Microsoft IIS webserver.

Book review: "Xen Virtualization" by Prabhakar Chaganti (Packt Publishing)

I recently received a review copy of the book "Xen Virtualization" by Prabhakar Chaganti (Packt Publishing) and finished reading it a few days ago.

The subtitle "A fast and practical guide" is a matching description - I managed to read the ~130 pages over the course of a week. The book is by no means an exhaustive reference manual, but it gives the reader a good overview about Xen and assists with performing the first steps and getting started.
