Good afternoon and welcome to another edition of Blogrotate. Though I have been contributing to Blogrotate since its inception, this is the first time I have had the honour of posting it myself. Go me!
Welcome to the 186th Edition of Log Buffer. Lots to report this week, so read on…
I want to post the slides of the two presentations I did. My first presentation was a double slot session about Oracle Clusterware internals. My second presentation was about how we designed and run 1TB MySQL database in high availability setup.
Huzzah! It’s official, Perl 5.12 is out! If you haven’t already, check out the changelog! As one might expect, this little piece of news made its way on several blogs, both internal and external to the Perl community.
I have successfully compiled and installed DBD::Oracle on Windows 2008 Server 64bit operating system today. I used the latest version of DBD::Oracle 1.24, version 22.214.171.124.0 for 64bit Windows of Oracle’s Instant Client Package – Basic along with the Instant Client Package – SQL*Plus and finally the Instant Client Package – SDK. Here are some instructions that will help with the install.
Here’s a sneak peek at a video matrix — this is all the videos that include Pythian Group employees at the MySQL conference. I hope to have all the rest of the videos processed and uploaded within 24 hours, with a matrix similar to the one below (but of course with many more sessions).
This is not my notes about the MySQL conference that just occurred. These are my thoughts about MySQL conferences in general. During this year’s conference, I heard a lot of concern about whether or not O’Reilly would have a MySQL conference, and whether or not Oracle would decide to sponsor.

Recently I’ve been puzzled with the performance difference observed between 11GR1 and 11GR2. As part of the investigation I’ve decided to compare session stats from both 11GR1 and 11GR2 and found that there is a big difference for session cursor cache hits. But the number of session cursor cache hits I’ve been observing in 11GR2 just didn’t made any sense while being absolutely fine in 11GR1. An overflow was certainly a possibility, though in 2010, it’s not like someone should be counting every bit especially if they didn’t in 11GR1! Anyway it was worth a shot so I’ve decided to check it out…
It’s a busy time of year for Pythian. With many of our team tied up on client engagements, away at MySQL conference this week, and Collaborate 2010 next week, I’m pinch hitting as volunteer editor in helping to pull together this week’s edition of Log Buffer. Enjoy!
Good morning everyone and welcome to another edition of all the news fit to reprint. Last week iPad news was the number one topic on the hearts and minds of most places I visit, let’s see if the iPad can last another week or if a new champion will be crowned. Call or text your votes to … oh wait that’s someone else. :)
