I’m excited to be teaching at Amis for one day next week and the more informal event the previous evening. Registration form is here. Showing my beloved pictures with beer in hand? Sounds perfect although perhaps I should make sure the demos are working correctly before opening the bottle 😉 Lots more technical posts to… Continue reading Advert: See you in Utrecht next week

Is it really that time already? I’ll be working in London, but for those of you who can make it, this just in from Thomas Presslie … “The annual Scottish Oracle Conference is being held in Glasgow on 27th May 2010.  Now with five streams and keynote by David Callaghan, Senior Vice President Oracle, UK,… Continue reading Advert: UKOUG Scottish Conference next week

I will get back to the stats stuff at some point, but I’m quite busy at the moment working on something that I can’t talk too much about, but which is throwing up enough generic issues to talk about. This is one that I meant to blog about ages ago when I first noticed it… Continue reading Resource Manager and 11g

I’m pretty self-concious of the amount of waffle that surrounds any technical content here, so let’s get the technical bit out of the way first, then the waffling can come later … I finally tracked down the mistake I didn’t make in part 6a, but thought I’d identified and fixed in part 6b! Here are… Continue reading Statistics on Partitioned Tables – Part 6d – COPY_TABLE_STATS – A Light-bulb Moment

If I didn’t laugh, I’d cry. Mid-way through a series of posts, the next one of which I plan to talk about some of the myriad bugs and related patches for DBMS_STATS in 10.2.0.4, I discovered via several blogs that the 10.2.0.5 patchset for Linux x86-64 has been released 😉

[Phew. At last. The first draft of this was dated more than two weeks ago …. One of the problems with blogging about copying stats was the balance between explaining it and pointing out some of the problems I’ve encountered. So I’ve broken up this post, with a little explanation first …] Oracle have a… Continue reading Statistics on Partitioned Tables – Part 6a – COPY_TABLE_STATS – Intro

Sigh … these posts have become a bit of a mess. There are so many different bits and pieces I want to illustrate and I’ve been trying to squeeze them in around normal work. Worse still, because I keep leaving them then coming back to them and re-running tests it’s easy to lose track of… Continue reading Statistics on Partitioned Tables – Part 6b – COPY_TABLE_STATS – Mistakes

Thanks to Marco mentioning it on Twitter, I downloaded and installed 11gR2 for Windows from OTN this evening. The reason I had to switch to OEL on VMWare was because of the delay on the 11gR2 Windows release, but I’ll give it a try and see which works best for me. Installation was certainly a… Continue reading 11gR2 for Windows 64 on OTN

Some people might have noticed that the blog has been down a few times over the past week, particularly on Friday. The server that the site and blog is hosted on has been subject to some sort of hack attack and as a result it was moved to a new server and all privileges were… Continue reading Outages

In one of my Hotsos Symposium 2010 posts I mentioned that Peter Stalder had plugged some test results from an earlier blog post into Neil Gunther’s Universal Scalability Law to see how well the model applied. Peter’s posted his slides now and I’ve added the URL to the comments thread of the original post so… Continue reading Time Matters: Throughput vs. Response Time – Part 2
