Update: In Oracle 11g upwards you can use V$DIAG_INFO for getting your own session’s trace file name too ( diag.sql script). But on earlier versions or if you want to see the current tracefile name of another, you still need to use the V$PROCESS approach below. Note that V$PROCESS in 11g (or 11.2?) has a column TRACEFILE that shows the entire path+name of a process tracefile (however there seems to be a bug in 12.1.0.2 where the field is ..

Update: As this post was written many years ago, you should check out newer Snapper articles/videos: /2013/02/18/snapper-v4-02-and-the-snapper-launch-party-video/ My friend asked today a question that how to identify why his Oracle 9.2 database has suddenly started generating loads more redo than usual. So obviously I recommended him Snapper as first thing, it’s perfect for ad-hoc analysis like that! ( I know I sound biased but if ....

I recently read an article on Techcrunch on how web 2.0 had undoubtedly made an impact, but had yet to truly make money. From my stance they is really one way to make money on the web, which is through advertising (paid subscription services are dying). This can either be done through a simple banner ad, or something that can more easily be deemed a qualified lead or referral. Ads will always be there, but if web 2.0 is to start making mone....

This picture is of an IBM Model 3380 Hard Drive from 1981. Because it looks like a nuclear device or jet engine, I was able to convince my neighbour that I was generating my own nuclear power from now on, as well as the people at the Chrysler convention that it was an electric engine for a transport truck (I was passing them when going to a high school tech presentation at Bingemans where I used this as a fun prop). My pranks know no bounds..

There was a question in a recent Oracle-L thread about various uses of autonomous transactions. Autonomous transactions can be very useful for a PL/SQL application logging, but sometimes they are also abused to cope with bad application design (like avoiding mutating table errors in triggers etc). I’m not going to start on that topic here though, but instead presenting another case where autonomous transactions have helped me to work ....

I’m finding it a growingly interesting balance in consuming versus producing information. I also feel with the increase in availability of information, the barrier to entry in so many areas are shrinking rapidly. I think of some of the areas where the barriers to entry are typically much higher. 15 years ago we would have never seen a 23 year old as the CEO of a company valued at 15 billion dollars. While my vantage point even within the bu....

As I’ve become more or less a web 2.0 whore. I’ve also had a great interest in web 3.0 and what it will fortell. Most believe natural language and the semantic web will play a large role in that. And while it will that will not be the end result of web 3.0. While web 2.0 included AJAX and Flex, that really doesn’t fully encompass what they are. Web 3.0 to sum it up most simply will be about reducing the noise of the web. While I can take ve....

Every so often I re-read a book that I read years ago to remember what it is about. Mostly, I re-read sci-fi or notable works such as Neuromancer (William Gibson) or The Hitchhiker’s Guide to the Galaxy (Douglas Adams) since those are the types of books that I kept over the years. However, I kept a book from 1989 called Life with UNIX (Don Libes & Sandy Ressler) that I remember using as a good UNIX reference a long time ago. ..

Products Company - For me this may the be most obvious and strongest reason for any of the four groups to begin using Twitter. It’s quite simple, people use your product or service, people talk about your product or service, people ARE talking about your product or service on Twitter. Regardless of whether you want it or not, people are going to talk and they’ll speak their minds. I don’t believe I know of a company that wouldn’t want to kn....

After a year of living in Silicon Valley it’s hard not to be consumed with the excitement around one startup after the next. The hopes of being the next eBay, Google, or Facebook lie within many of individuals in the area. Some pursue it, some write it off as a distant hope, and still others just want to be a part of them at some point. But why would someone just want to be a part of Google 5 years ago? The first thing that comes to mind ....

I went to go and do some roller racing earlier this week, at a pub called the Horseshoe in Clerkenwell. The Rollapaluza guys were being filmed, and running a free-for-all race. First time on the rollers, I managed 23.48s, which turned out (once a couple of people had disappeared) to be good enough to get me to the quarter finals. clefty from LondonFGSS took a few photos, so I figured I’d post them here:

Spend five minutes talking to me about technology or business and you’ll quickly realize I’m a fan of Adobe AIR. Adobe has done a very good job building a cross-platform runtime, and providing tools that make the transition from the web to the desktop quite minimal. First to elaborate why I like AIR. For one I’m a fan of web 2.0, the sites feel cleaner, smoother, and drive new capabilities. Versus most desktop applications that are starti....

As I write this, I write only from my vague knowledge of where revenue’s come directly from. However, I do hope to back this up in the future with more numeric backing. My title of the post may be quite strong and negative, but I feel it has reasonable ground to stand on, based on one simple principle. A corporation should stick to and focus on it’s core business, and exhausting resources outside it’s core business could end up costing them....

What is the secret to happiness? Surprisingly, this question can be answered more and more definitively. I want my work to be conductive to the happiness of myself and others, and I believe agile methods can help me do that. Years of research into happiness can be summed up in a simple sentence. You all know what gives you a happy life. It’s not anything strange or unexpected. It’s simply enjoyable progress towards a meaningful goal.

Two of the hardest problems of software development are integration and what we could call business-IT alignment: The whole organization working towards the same goal. SOA claims to address both of these problems. After listening harder than I’ve ever done before to SOA evangelists, I think I understand what mechanisms SOA proposes to solve these problems. I think the idea of SOA is based on a set of rather bold claims:
