"Mr. Upgrade" on DOAG.TV

Mike may be too humble to post this himself, so I will point out that the Oracle user group in Germany (DOAG) has published a video of an interview with Mike about upgrade to Oracle Database 12c. The interview is in German, so if you speak the language, please enjoy:

Those who  are inclined to view the video may also want to pay attention to the announcement about upgrade workshops in Germany. See Mike's blog entry about our upcoming events for more information!

Avoid Poor Performance and Wrong Results in 11.2.0.4

One of the best notes in MOS got refreshed last night for Oracle Database 11.2.0.4. It has not only information about performance bugs but also about the worst and meanest category of issues, wrong query result bugs. Those are the ones I call the "sleeping beauties" as you as a DBA usually won't recognize them. It is recognized at the application level when the result of a report is incorrect or instead of 4 rows just 3 rows get delivered in the output. Therefore you should be highly aware of those and add this note to your bookmarks.

MOS Note 1645862.1Things to Consider Before Upgrading to 11.2.0.4 to Avoid Poor Performance or Wrong Results

And in case you don't want to move to Oracle 11.2.0.4 but searching for information and known issues in Oracle 11.2.0.3 or Oracle 11.2.0.2 then please find the corresponding documents:

Why cows can fly! Believe it or not ...

A colleague of mine, Murilo from Oracle Brasil talked about our roles at Oracle (but this applies to any other software company in the market I'd guess).

Do you believe in flying cows?

  • Sales
    In Sales you'll sell a customer that cows can fly
  • Presales
    The presales consultant will have to do a presentation showing the ROI, TCO and KPIs of flying cows. She or he may have also a screenshot demo in Powerpoint showing flying cows. 
  • Consulting
    The consultant is the person to install the flying-cow piece of software at the customer site and embedd it into the customer's environment. Unfortunately the poor consultant finds out that in this environment cows actually don't fly well. In fact, cows don't fly at all. So the consultant may raise an SR before going home.
  • Support
    The SR gets into the queue of a Support engineer somewhere in the world. The Support engineer wonders about this SR as she or he has never heard of flying cows before. So she/he takes a look into the doc. And there's nothing mentioned about flying cows. But the doc doesn't say anything about "cows can't fly" so a testcase will be required from the customer or the consultant to show the non-flying cows. Poor Support engineer: she/he can't even file a bug for it as the doc doesn't say anything about the flying-cow-feature. 

Guess how that story will end?
Does it sound familiar to you? To me it does ... a bit ;-)
And I'm glad that I'm working in Development :-)

So you may watch this tiny little video in your spare time ...

-Mike

PS: Thanks to Murilo - and I phrased it in my own words as I still burst out laughing and crying at the same time when thinking about our conversation :-) But credits go to him - obgrigado!!!

PPS: No offense to anybody in any role in a software company ...

OUGN - Great Conference!!! Download the Slides

The cruise is over :-) And what an excellent event. Congratualations to Alice, Frank, Øyvind and all the other great people from the OUGN. I had plenty of fun, met great people - and here are the slides for the two presentations I gave:

  • Hitchhiker's Guide to Oracle Database Upgrades
    This slide deck will give an overview about how to approach a database upgrade project, the risk and costs of not upgrading and the news in the Upgrade space for Oracle Database 12c upgrades

  • What's New in Data Pump in Oracle 12c
    This overview about general Data Pump best practices highlights also all new Oracle Database 12c features with Oracle Data Pump such as the new COMPRESSION_ALGORITHM and its benefits, new TRANSFORM clause and the "killer feature" Full Transportable Export.

Hope to see you all next year again - and hopefully we'll have a again a quiet sea :-)

Going to Norway for the OUGN Conference

I'm back in business after being out for almost two weeks. And tonight I will fly out to Oslo in Norway to participate in the OUGN Spring Conference 2014. It's my first user group conference in Norway and it will be very special as it will happen on a ship. No escape :-)

And Lufthansa's pilots did a great job in making my travel another nice Lufthansa surprise package. Due to the upcoming 3 day strike my flight to Oslo got canceled last night at 18:25h - as if Lufthansa wouldn't know about the strike days before (it got announced last week). But I could rearrange my travel and now I'll fly out a day earlier. I still feel very sorry for all the families and travelers getting stuck somewhere close to the Easter holidays. All LH Hotlines ("cold"line or "dead"line would fit better) where broken yesterday. Even the Senator "hot"line was out of order. As if my favorite airline wouldn't have known upfront that people WILL HAVE TO CALL when they cancel 3800 flights.

Anyway, I'm looking forward to this great event in Norway. Preparing myself right now with some great tunes of two of my all time favorite Jazz musicians from Norway, Jan Garbarek (saw him playing live several times) and  Ketil Bjørnstad.

My presentation will be:

CU soon :-)
