A friend pointed out a link to one of my blog postings<\/a> over at Burleson Consulting’s website that I wasn’t aware of.<\/p>\n

Whilst I appreciate Don Burleson’s fulsome praise of my communication skills, I think it’s only fair to make a few points of clarification.<\/p>\n

1) I was concerned that readers might misinterpret my intentions when I wrote that blog entry, to the extent of saying the following, which Don didn’t quote<\/p>\n

“When you see the solution, the words ‘Silver’ and ‘Bullet’ might pop into your mind. If so, let me point out that I worked it out by poring over execution plans, trying different approaches in full-sized test environments and, when you look at the problem, it’s actually a very localised problem with a large query”<\/i><\/p>\n

In fact, if you look at the whole series of three blogs and the follow-up comments, you’ll see that this exercise might have been a quick fix, but getting to the bottom of why it might have helped took some time. <\/p>\n

http:\/\/18.133.199.212\/?p=820 href="http:\/\/18.133.199.212\/?p=818">http:\/\/18.133.199.212\/?p=818 href="http:\/\/18.133.199.212\/?p=813">http:\/\/18.133.199.212\/?p=813 I don't know *why* it worked, how can I be sure that it's really fixed the problem and hasn't introduced new problems? Even if I decide to ignore such details, an inflexible fix like this might well cause problems when you upgrade to future versions of Oracle, because a new and more efficient execution plan is unavailable as a consequence. The fact is, I always worry about such an apparently<\/i> easy solution because there are likely to be unexpected consequences. There are few free lunches in this business.<\/p>\n

2) The link is broken (although I’m sure it wasn’t when it was first pointed out to me a couple of weeks ago). The correct links are listed above.<\/p>\n

3) <joke>Oh, and I *do* wish people wouldn’t link to old, pre-Serendipity blogs. It means I have to go and tidy up the formatting ;-)<\/joke><\/p>\n

Anyway, if you still believe in the power of Silver Bullets, this<\/a> might convince you otherwise, as well as giving you a few laughs.<\/p>\n","protected":false},"excerpt":{"rendered":"
