I just came back from the DOAG APEX Connect 2016 conference in Berlin ... very nice location, great content and the wonderful APEX community to hang out with ... always a pleasure. This time we felt a little bit pink ;)
As promised, you can download the slides and the demo script (as is) from my site.
Instructions are included.
See you at KScope in Chicago, #letswreckthistogether .
Cheers and enyoy!
Where You Are Now
OBIEE 12c has been out for some time, and it seems like most folks are delaying upgrading to OBIEE 12c until the very last minute. Or at least until Oracle decides to put out another major version change of OBIEE, which is understandable. You’ve already spent time and money and devoted hundreds of resource hours to system monitoring, maintenance, testing, and development. Maybe you’ve invested in staff training to try to maximize (more...)
I’m going to beat the OUG Scotland conference on 22nd June, and one of my sessions is a panel session on Optimisation where I’ll be joined by Joze Senegacnik and Card Dudley.
The panel is NOT restricted to questions about how the cost based optimizer works (or not), we’re prepared to tackle any questions about making Oracle work faster (or more efficiently – which is not always the same thing). This might be configuration, indexing, (more...)
Someone pinged me earlier today and said, “Do I even really need to know about logs in Enterprise Manager? I mean, it’s a GUI, (graphical user interface) so the logs should be unnecessary to the administrator.”
You just explained why we receive so many emails from database experts stuck on issues with EM, thinking its “just a GUI”.
Yes, there are a lot of logs involved (more...)
From time to time we see a complaint on OTN about the stats history tables being the largest objects in the SYSAUX tablespace and growing very quickly, with requests about how to work around the (perceived) threat. The quick answer is – if you need to save space then stop holding on to the history for so long, and then clean up the mess left by the history that you have captured; on top of (more...)
It’s extremely nice to have a big audience. It’s very flattering that people care enough about what I say to be bothered to read it. The problem with having a large audience is people can get a very demanding at times.
I’ve mentioned the 1% rule (or 1-9-90) before. The number of people producing content in an internet community is really small compared to the number of people consuming it. That discrepancy can cause problems when (more...)
I was working on a minor problem recently where controlfile autobackups were written to the wrong location during rman backups. Taking controlfile autobackups is generally a good idea, even if you configure controlfile backups yourself. Autobackups also include an spfile backup, though not critical for restore, is still convenient to have. And autobackups are taken not only after backups, but more importantly every time you change the physical structure of your database, like adding or (more...)
I was presenting at the UKOUG event in Manchester on Thursday last week (21st April 2016), and one of the sessions I attended was Carl Dudley’s presentation of some New Features in 12c. The one that caught my eye in particular was “DDL Logging” because it’s a feature that has come up fairly frequently in the past on OTN and other Oracle forums.
So today I decided to write a brief note about DDL Logging (more...)
Today’s video gives a quick run through of flashback version query.
If you prefer to read articles, rather than watch videos, you might be interested in these.

- Flashback Data Archive (FDA) Enhancements in Oracle Database 12c Release 1 (12.1)
In this series of blogs about Continuous Delivery and the Oracle database, I describe how to automate deployments (installations). In the previous two Blogs I have described the tools and techniques used to create and install migration scripts.
In this Blog I will describe the ‘(un)happy flow’ for a database deployment: what to do if the deployment (installation) is correct (the ‘happy flow’) and what to do if it goes wrong (the ‘unhappy flow’)?
It’s not important that you know the answer. It’s important you how to get the answer!
I’m pretty sure I’ve written this before, but I am constantly surprised by some of the questions that come my way. Not surprised that people don’t know the answer, but surprised they don’t know how to get the answer. The vast majority of the time someone asks me a question that I can’t answer off the top of my head, (more...)
How much do you know about the big push to BI Publisher reports from Information Publisher reporting in Enterprise Manager 13c? Be honest now, Pete Sharman is watching….
I promise, there won’t be a quiz at the end of this post, but its important for everyone to start recognizing the power behind the new reporting strategy. Pete was the PM over the big push in EM13c and has a (more...)
