As promised earlier, here’s a blog post about some of the thinking behind the course I’ll be teaching in Prague on 14th/15th April (assuming enough people are interested in attending). Why I decided to do itSeveral factors appealed to me when Oracle first asked whether I’d be interested :- 1) It’s about two and a… Continue reading Advert – Oracle 10g Performance Analysis

I’m pleased to see a few posts debating the (non)-application of quarterly Critical Patch Updates. Here are a few examples … Is Poor Security Hygiene Rampant?Do DBAs care about Oracle’s latest Critical Patch Update?Survey finds that 66% of Oracle users never install critical patches All of which seem to have been kicked off by Pete… Continue reading CPUs again …

That number in the title is not a joke or an attempt to drag out the pain. However, OraNA has been flooded with ‘8’ posts this week, so I thought it worthwhile to post a quick list of some really nice technical posts I’ve noticed over the last couple of weeks. I was just waiting… Continue reading 8 Useful Technical Posts …

Rest assured that I’ve watched… Continue reading The Reality Gap (4) – It’s never the SAN

I need to tread carefully, in case I get ticked off by Dave Edwards, but there’s some seriously good stuff floating around this week. The more the merrier, I say, particularly when they’re pushing up the standards. (Is that ok, Dave? Three links, and I didn’t add a single word of analysis!)

As a regular reader of Jonathan Lewis’ blog, I like the way he prefixes seminar announcements and the like with ‘Advert’. (I looked for an example to make sure it was ‘Advert’ and not ‘Advertisement’, but he deletes them after a few days!)
