… and the first shockingly bad photo on the blog for this conference, too. With some gentle encouragement from Mads, we decided to set up and try Skype video. As well as making it easier and cheaper for us to stay in touch, we’re both finding it weird, fun and reassuring – a completely different… Continue reading Another 2008 Innovation …

I noticed that the agenda for this year’s conference is online. I was very pleased to have two abstracts accepted but didn’t mention it before now because there was a possibility that I might replace one of the presentations with an alternative. In the end, I’ll be going with the two original abstracts I mentioned… Continue reading UKOUG Agenda Online

In his comment on the last post, John Beresniewicz mentioned the following property of DB CPU :- “… ‘DB time’ fully contains ‘DB CPU’ and both are measured values (which means in particular that ‘DB CPU’ is not inflated by runq time)“ I’d like to talk about the end of that sentence in particular. About… Continue reading Time Matters – DB CPU

I noticed Christian’s blog a few weeks ago and forgot to mention it, but it’s been added to my blog-roll now. His book turned up yesterday and, despite the fact it’s in a long queue of books to read, I’m looking forward to it. A very quick initial glance was quite seductive (if it doesn’t… Continue reading Christian Antognini

[In retrospect, the title of that first blog post might have suited the subject, but doesn’t translate too well for subsequent related blog posts. That was a lack of planning or foresight on my part. These blog posts are tumbling out of my head in a fairly incoherent way. Maybe when they’re finished, I could… Continue reading Time Matters – DB Time

Knowing myself, I doubt it will end up quite like this, but I thought I’d throw together an approximation. (I must say, the schedule builder this year is a significant improvement on previous years. It doesn’t have a jet-lag adjustor, but you can’t have everything.) Sunday, Sep 21 10:00-11:30 Building an Oracle Real Application Clusters… Continue reading My Openworld Schedule

When I was teaching the 10g Performance class at my last customer site, I remarked that the total number of seconds you see in the “Top 5 Timed Events” section of a Statspack or AWR report will often be greater than the total number of seconds between the snapshot intervals. For example, this is the… Continue reading Time Matters – An Infinite Capacity for Waiting*

[Disclaimer – this is a review of a free copy I received from Oracle Press in the UK] Well, it turned out that I had requested the ASM book (or “Oracle Automatic Storage Management: Under-the-Hood & Practical Deployment Guide“, to give it it’s full title) as one to review. It turned up a couple of… Continue reading Book Review – Oracle ASM

As previewed by Kurt on his blog, I’ll be giving the 10g Performance seminar for Oracle Belgium on the 16th and 17th October (Oh, and thanks for the kind words, Kurt). The reason I didn’t mention it before now was because I needed to update the agenda to reflect the course a little better. The… Continue reading Advert – More Seminar Dates

I’ve been working with Audit Vault 10.2.3 on AIX recently and ran into a problem that someone else might one day. I decided to capture the output as best I can and blog about it later. (As I don’t have the same system available any more, the formatting might leave a bit to be desired… Continue reading Hanging Audit Vault Warehouse Refresh Job
