Dbvisit Reporting…

I try to stick close to core Oracle technologies and steer clear of product endorsements, but over the years I’ve bumped into the ladies and gents from Dbvisit a number of times and they have been consistently cool and consistently on the money with their products. At Oracle OpenWorld 2012 I bumped into Arjen Visser who told me about their new product called Dbvisit Reporting, so I asked him to keep nagging me until I tried it out. When we met at UKOUG 2012 I still hadn’t tried it, but he had been too polite to bug me about it. This weekend it made it to the top of my list. :)

Throttling IO with Linux

Why?

I guess the first question which comes to mind when reading this title is ‘Why’? For a database, but I guess for any IO depended application, we want IO’s to be faster, not throttle them, alias make them slower. Well, the ‘why’ is: if you want to investigate IO’s, you sometimes want them to slow down, so it’s easier to see them. Also, (not so) recent improvements in the Oracle database made great progress in being able to use the available bandwidth by doing IO in parallel, which could strip away much of the ability to see them in Oracle’s popular SQL trace.

Tom Kyte in Moscow – 2

On December 11th Tom Kyte performed “AskTom in Moscow” for the second time (first time was almost three years ago in February 2010). I was there and enjoyed presentations, tweeted a lot about the content and in the end I’ve won a signed copy of the Expert Oracle Database Architecture (2nd edition, in Russian)!

The start

A glass for questions. It was full in the end of the day

Small mishap with this website…

Sorry, for those who where missing, or needed, some of the info here yesterday. Due to a small mishap regarding an incorrect URL update, some annoying redirects occurred. :S

AMIS vat Oracle OpenWorld 2012 samen in Speciale Whitepaper

WordPress 3.5…

WordPress 3.5 has landed. You can download it from the usual place.

The auto update went fine on all five blogs I manage (they are not all mine :) ).

Happy upgrading!

Cheers

Quiet Release MySQL Plugin 12.1.0.1.2 — Bug Fixes

This is just a small bug-fix release of the plugin. It has actually been quietly released for a while now. If you have downloaded the plugin recently, you have the latest version. To be sure, check the version in the Console, or you can see it in the file name.

There are two bugs fixed:
1. Deployment on an OMS hosted on Solaris didn’t work. (And I suspect it could be the same for Agents on Solaris.)
2. Changing thresholds on the metrics caused the error “Modification of Target Monitoring Settings has Failed”. Also, applying monitoring template was failing for the same reason.

Catch-up

Looking back at the comments audit trail on wordpress I see that I’ve got nearly two months of comments waiting for answers – and some of those answers need serious thought that I haven’t had time to supply yet. But I’ve got a (fairly) free day on Thursday so I’ll see what I can do to bring the comments up to date.

I’ve just had a great day at the Trivadis CBO days – Maria Colgan (the optimizer lady) on the 20th anniversary of the CBO, then Joze Senegacnik on transformations, me on Strategies for Statistics in 11g, ending with Randolf Geist on Parallel Execution (including a reference to one of my older blog items which I now think could well be wrong – so I may have to spend Thursday reviewing it and looking at his analysis instead of working through the comments).

Viewing Figures

It’s time for another landmark. The blog hit 3,000,000 views on 30th November  - but I’ve been too busy to do my usual analysis of posts. The latest half million took 42 weeks (five weeks less than the previous half million increment) and here are the latest stats on popular views:

First the top five across the lifetime of the blog (excluding the home page and opening menu) and the old faviourites haven’t changed:
