One of the best notes in MOS got refreshed last night for Oracle Database 188.8.131.52. 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 1645862.1: Things to Consider Before Upgrading to 184.108.40.206 to Avoid Poor Performance or Wrong Results
And in case you don't want to move to Oracle 220.127.116.11 but searching for information and known issues in Oracle 18.104.22.168 or Oracle 22.214.171.124 then please find the corresponding documents:

There will be a lot of travel within the next few weeks. So please keep your fingers crossed that Lufthansa pilots don't go on strike for their ridicolous goals again. And I hope to see you in one of our upcoming workshops within the next weeks somewhere in the below cities.

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 ...
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 ...

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 theycancel 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.
