An Oracle Instance is Like An Upmarket Restaurant

I recently did an Introduction to Oracle presentation, describing how the oracle instance worked – technically, but from a very high level. In it I used the analogy of a restaurant, which I was quite happy with. I am now looking at converting that talk into a set of short articles and it struck me that the restaurant analogy is rather good!

Here is a slide from the talk:

The BBC has “Stolen” my Interesting Shortest Day Facts

Today, the 21st December 2014, is the “shortest day” in the Western Hemisphere this year, the day in which the period of daylight is shortest (it’s the 22nd if the last Leap Year is more than 2 years ago).

I’ve blogged before about how the evenings start drawing out BEFORE the shortest day and, despite it not being an Oracle technical post and was also one of my first posts {when almost no one came (more...)

Friday Philosophy – my Funniest “PC Support” Call in Years

Those of us who work in IT often find ourselves being called by friends and relatives to help with issues they have with their home computer. No matter what branch of IT we work in, it’s IT {they figure} so of course we can fix their PC problems. It’s like any scientist can probably explain what the Higgs Boson really is and reverse the polarity of the neutron flow.

Mothers and other elderly relatives are (more...)

UKOUG Tech14 Suggestions for Intro Talks and My Picks of the Rest

As I mentioned in my last post, we tried to organise a thread of intro talks into day one and two of this year’s UKOUG Tech14 conference (you can see the agenda grid here). It was not complete but I thought I should pull it into it’s own post and add in what I would recommend from the overall agenda for people who are relatively new to Oracle RDBMS.

How do you Explain Oracle in 50 Minutes?

I’ve done a very “brave”* thing. I’ve put forward a talk to this year’s UKOUG Tech14 conference titled “How Oracle Works – in under 50 minutes”. Yes, I really was suggesting I could explain to people how the core of Oracle functions in that time. Not only that, but the talk is aimed at those new to Oracle technology. And it got accepted, so I have to present it. I can’t complain about that (more...)

Conferences and the Etiquette of Meeting New People

One of the reasons I like user group conferences is meeting new people in my “area” – these people at the conference not only like technology and probably some of the same technology I do but, as they are at a conference, are probably inclined to learn stuff, meet people and maybe share ideas. I’m not actually very good face-to-face socially with people I do not know, so I like to tilt things in (more...)

Why is “Dave Unknown” Trying to Social Media With Me?

I know some people share my opinion on this and others totally disagree – but I fail to appreciate why people I have never met, spoken with or care about want to Social Media with me. If we have not met but there is a high probability we share unusual interests then OK, perhaps – but the fact that we both can spell Oracle or know what a gene is does not count as unusual (more...)

Conference Organisation from the Inside – UKOUG Tech14

An interesting experience I have had this year is being more involved in helping organise the annual UKOUG Oracle Technical Conference – Tech14 this year. I fully intended to blog about things as we progressed, but it never happened. But I thought it would be interesting to do a couple of blogs about it, for anyone interested,

If you have never helped organise a conference or user group meeting then you probably think there is (more...)

Audio semi-Visual Presentation on Clustering Data in Oracle

I suppose it had to happen eventually but one of my presentations has ended up on YouTube. It’s a recent presentation I did for the Oracle Midlands user group in September.

The topic is (as the title of this blog post hints at!)Boosting select performance by clustering data. The video consists of the slides I presented, changing as the presentation progresses, with my audio over the top. It goes on for a bit, (more...)

Next Club Oracle London – 12th November 2014

The next Club Oracle London is taking this place, on Wednesday 12th November. You can find the details here.

The coming event will have presentations by James Anthony, Dominic Giles and Jason Arneil in 12C in-memory database, key facts (more...)
