Expect live demonstrations as the major content – I promise to keep the marketing part to a minimum :-)

Another year has passed. I take the opportunity to thank you for visiting and to wish you a Happy New Year 2016!

In case you didn’t recognize: That is supposed to look like fireworks, The Oracle Instructor style ;-)

2015 was a great year for uhesse.com with 345,000+ views and the crossing of the one million hits threshold. Top countries with more than 4,000 views in 2015 were

This is how an upgrade with pluggable databases looks conceptually:
You have two multitenant databases from different versions in place. Preferably they share the same storage, which allows to do the upgrade without having to move any datafiles

You unplug the pluggable database from the first multitenant database, then you drop it. That is a fast logical operation that does not delete any files

Next step is to plug in the pluggable database into the multitenant database from the higher version

If your Oracle Database fits into the buffer cache, we will put all segments into it now upon access – no more direct reads:

SQL> connect / as sysdba
Connected.
SQL> select banner from v$version;

BANNER

The requirements are met here, I don’t need to force anything:

Another annual DOAG conference has passed, and I can only say the very best about it: Perfectly organized, large and modern location, impressive list of well known speakers and over 2100 attendees – wow!

My presentation Best of RMAN was scheduled at the first slot on the first day, so I was a bit concerned whether many people would attend that early. It turned out that the room got so full that I was asked by the organizers to deliver the same talk again next day – which I happily did, again with a packed room :-)

Less famous 12c New Feature: If you do Create Table As Select (CTAS) or a direct load into an empty table, we will automatically collect optimizer statistics:

The recipients of the Oracle University Leadership Circle Quarter 1 Fiscal Year 2016 have just been announced. That is a corporate award for the best instructors worldwide according to customer feedback. Not less than four (!) come from our small team of 14 instructors:

Yes, we have a great team – supported by a great manager: Thank you, Richard! Congratulations to everyone in the circle this time, I feel honored to be listed together with you!

Say I have created a new tablespace recently and did not yet take a backup of the datafile. Now I lose that datafile. Dilemma? No, because I can do an ALTER DATABASE CREATE DATAFILE. Sounds complex? Well even if I wouldn’t be aware of that possibility, a simple RMAN restore will work – as if there were a backup:

Oracle University has introduced a new format that suits the way many learn today: Oracle Learning Streams

Although I do not expect that this format will replace classroom training, I consider it a great enhancement – coming with a price like most good things…

As you can see, I’m happy to contribute to it in my area of expertise: You can find me here in the Database Stream.
