Oracle Midlands : Event #2

Just a quick reminder that the second Oracle Midlands event will be taking place on 25th March 2014.

At this event you will get a chance to see Graham Wood (my Dad) speaking about “Advanced ASH Architecture and Usage” and Nikolay Manchev speaking about “Using Clusterware 11g to protect single-instance databases”.

The event is sponsored by those kind folks at Red Gate Software, which means it is not going to cost you anything to come to the event. You can register here.

These events live or die based on your support. Please spread the word and come along. See you there!

Cheers

Copyright Theft: WordPress.com not making my life easy!

Yesterday I was informed about someone stealing my content again. I take a pretty hard line to this these days. I used to be a little unsure about how to approach it, but now I just hit them with a DMCA take-down notice straight away. I’ve not got time to explain to everyone and their dog about copyright law…

So the current thief has nicked 35+ of my articles. I went to the WordPress.com DMCA Notice page and they say the usual stuff, except that you have to file a separate notice per blog post. All other services I’ve encountered allow you to post a single notice, listing all the offending posts. Not WordPress.com! (see update below)

IT Stockholm Syndrome

Shrugging

Random thoughts on a Friday afternoon…

We’ve all got problems. More to the point, every IT department or team has problems of some kind. It’s why we hire consultants, buy products, start long and arduous journeys into the great unknown depths of root cause analysis, and so on.

What fascinates me is the level at which we come to identify with our problems. When I’ve gone into an environment to deliver recommendations, the conversation usually goes something like this:

Subquery Anomaly

Here’s an oddity that appeared on the OTN database forum last night:

We have this query in our application which works fine in 9i but fails in 11gR2 (on Exadata) giving an “ORA-00937: not a single-group group function” error….

… The subquery is selecting a column and it doesn’t have a group by clause at all. I am not sure how is this even working in 9i. I always thought that on a simple query using an aggregate function (without any analytic functions / clause), we cannot select a column without having that column in the group by clause. So, how 11g behaves was not a surprise but surprised to see how 9i behaves. Can someone explain this behaviour?

More and more jira resource endpoints implemented

I have added a lot more jira rest endpoints to the jira_utl package. The progress has been a little slow for the last week, since I have been elected president of the local danish user group, so I'm trying to get up to speed on that as well. The next week should be back to normal "speed"
