In a previous post, I talked about the method Skoll used to collect MySQL runtime information for non-default configurations. At the time, the runtime information was collected after all of the MySQL tests were executed, which means the runtime information was accumulated from all tests run. There was no way to decipher how each test contributed to this accumulated runtime information. A greater degree of granularity can provide better understanding of the MySQL runtime behavior.

To collect runtime information for each MySQL test, the Skoll client still compiles MySQL as described in the previous post. Instead of running the "mysql-test-run" script with no arguments (which runs all available tests in the source tree), Skoll client calls "mysql-test-run [TESTCASE]" to run one specific test. …

I did not usually go to “Elite” servers on Dell web site but looking at customers system today I went to check Dell Poweredge R900. This monster takes up to 4 Quad Core CPUs and has 32 memory slots, which allows to get 128GB of memory with 4GB of memory chips. This means upgrade to default configuration to 128GB of memory will cost you just $9600 (list price). I’ve been able to configure on a web the system with 8*2.5″ hard drives RAID and 2 CPUs (just as we usually configure PowerEdge 2950) with 128GB of RAM for about $16000. This means talking to Dell Sales rep it can purchases within $15000. This may sounds as a lot but if you’re memory constrained it is cheaper per GB than buying 32GB box for $6000

So am I scale-up advocate ? No. But it is quite frequently systems are designed to have “working set to fit in memory” to perform well and such systems can avoid good consolidation factor for such application, or would allow them …

We announced support for Oracle today. Specifically, Amanda Enterprise now protects:

• Oracle 11g on Windows
• Oracle 10g and 11g on Linux and Solaris
• Oracle Enterprise Linux

On Linux and Solaris, we took the approach of integrating Amanda with RMAN. Keeping with Amanda’s philosophy of using native tools as closely as possible, we allow Oracle DBAs to perform recovery right from within Oracle Enterprise Manager. Amanda takes care of restoring all files needed for a DBA to perform recovery specific to their need (e.g. table level recovery or point-in-time recovery).

For Windows, on recommendation from backup experts at Oracle, we integrated with their new VSS writer. This enables us to take quick snapshot …

Come find out the vendors that won InfoWorld's 2008 Bossie awards. You'll find some OSS leaders and some surprise winners. READ MORE

KEY ACCOMPLISHMENTS LAST WEEK

• Fixed some left over glitches in Skoll Client related to the Bazaar switch, mostly to deal with Java Runtime exec.
• Analyzed MySQL runtime data, but did not find clear differences between different configurations of MySQL. The analysis might need more granular runtime data, see next item.
• Modified Skoll Client to collect runtime information per MySQL test. Right now, Skoll Client runs mysql-test-run script (which executes all tests) then collects gcov runtime information for all tests.

KEY TASKS THAT STALLED LAST WEEK

• None

KEY CONCERNS

• None

TASKS IN THE UPCOMING WEEK

• Finish per test runtime information collection modifications.

While we were mostly excited to become part of Sun, there was at least one drawback too. MySQL had a worldwide policy of "Scandinavian style" 5 week vacations per year (4 Summer, 1 Winter week). Sun doesn't have such a worldwide policy, so most of us lost some vacation days there. But there is one group of employees that still enjoy this benefit... those of us that actually live in Scandinavia!

Those 4 weeks are however now gone for my part :-( So I thought I'll make a soft start to working by a) yesterday doing almost nothing and b) today blogging. A long long time ago before I left for my vacation Mark Callaghan requested more blog posts about MySQL Cluster, so I thought why not start with one right now. As previously noted there are many good MySQL Cluster bloggers out there, but admittedly some of their blog postings can be very …

Infoworld published the 2008 Bossies, Best Of Open Source Software. There are 8 categories and none of them are database:

• Collaboration
• Developer tools
• Enterprise applications
• Networking
• Platforms and middleware
• Productivity applications
• Security
• Storage

I had to look through several of them before I found the database category under Platforms and middleware. Slide 4 is the magic slide:

It says:

Introduction

The purpose of this document is to explain the power-efficeincy analysis proess, power-efficiency issues and solutions in MySQL database server as an example to help identify the right tools and procedures that support the development of energy-efficient application.

Analysis Process

The remainder of the document covers the detail information on each of the above procedures

So Cuil had lots of visibility because of their "data corruption" , showing "wrong" images to people.

However it seems like they still haven't cleaned up their mess.

Somehow they manage to place Geert Vanderkelen's picture in the search results for me.
Not the other way around however.

Well.. at least it isn't what they used to show :)

So Geert , if someone ever runs up to you and says "Hi Kris" , you know where they got the picture from :)
