Boat Successfully Arrived at Oracle HQ

Wondering what you can transport with a Sikorsky S-64 SkyCrane? For instance you could fly a Trimaran from the Bay to Oracle's HQ and park it in the lake :-)

Credits go to Cindy Lim for the picture - and you may watch the entire arrival via this link:

New interesting White Paper:
Oracle Multitenant Efficiency Study

There's a new White Paper available interesting for those who'd like to learn a bit more about the efficiency and the overhead of Oracle Multitenant in a fairly large environment:

More than one PDB in the same directory?

Can you create more than one pluggable database (PDB) within the same directory?
And how does the file naming work? Considering the fact each PDB's SYSTEM tablespace will be named system01.dbf by default the question is not trivial. 

This question got asked by a customer during one of the workshops in Switzerland last week. And the solution is straight forward. Thanks to Roy for trying it out yesterday at 170 km/h on our way back from Stuttgart :-)

Thanks :-)

Additional information:

Within ASM with OMF the file structure looks like this:

 1  select con_id, substr(file_name,1,90),tablespace_name from cdb_data_files
  2* order by 1

    CON_ID SUBSTR(FILE_NAME,1,90)                                                           TABLESPACE_NAME

LOCATION UPGRADE +++ Hamburg +++ May 15, 2014

My colleagues did an awesome job inviting so many people to our workshop in Hamburg next week. Therefore Marketing now moved it from the Oracle Office in HH to the following address:

PRIVATHOTEL EGGERS
Rahlstedter Straße 78
22149 Hamburg

Registration will start at 9am, workshop begin is at 9:30am - and we'll end straight at 4:30pm to catch our flight back to Munich. So please try to stay in time ;-)

Looking forward to see you all next week :-)

- Roy & Mike 

New Slides + Workshop Recap:
Luxembourg, Brussels, Vienna, Geneva & Baden

The first 5 of a long workshop run are over. Thanks for coming in, your patience for hundreds of slides and plenty of new (and some old) stuff. I really enjoyed seeing you and talking to you in Luxembourg, Brussels, Vienna, Geneva and Baden in the last 3 weeks.

And credits go to my colleagues Bernd Jodocy, Johan Vanden Bossche, Erwin Sulzgruber, Roger Wullschleger, Christiane Schlüter and all the others for setting up the events so well, did the inviations, assisted before, during and after the workshops - and gave me taxi rides between airports and locations. Thanks again for your great support!!!

I will try to follow up with the questions as soon as possible (if not done already). And - as promissed - here is the new slide deck:

Upgrade, Migrate & Consolidate to Oracle Database 12c

We've had an incredible 16000 downloads in the past 8 weeks - that's almost as much as in the 8 months before since 12c hit the streets. So I'd guess MANY are interested in how to upgrade, migrate and consolidate to 12c ;-)

Thanks again and if you have additions to the slides, please feel free to let us know!

-Mike 

PS: I deeply appologize again for the faulty HOL setup in Vienna. I gave my colleague Erwin a hard time - and he has sent out a workaround to you so you can complete the lab by yourself. Sorry again!!!

Upgrade Workshops - Locations

Dear all,

unfortunately somebody has missed to add the locations to the registrations page - and if you follow the Google Maps links you may drive apparently to a McDonalds burger place instead of the correct location (at least they'll offer free WLAN).

So please find the updated locations here - and enter the registration by clicking on the location/date directly.

I appologize for any inconvenience.
Hope to see you soon!

-Mike
