    New Webcast "Why Upgrade to Oracle 12c" available

    In December 2015 I did a recording for a webcast about "Why Upgrade to Oracle Database 12c" refreshing the content from a few months back.

    Webcast "Why Upgrade to Oracle Database 12c"

    Oracle's latest generation of database technology, Oracle Database, has some impressive new features. It offers great potential for a fast upgrade, simple migrations and consolidation, making more efficient use of hardware and delivering major improvements in management efficiency.

    Join our webcast on Upgrading to Oracle Database 12c and you will learn:

    • Why you still need to upgrade to Oracle Database
    • How to ensure that your applications are ready for Oracle Database 12c
    • How to evaluate and test all enhancements of the upgrade process plus other new features
    • Best practices to upgrade and migrate successfully 

    If you would like to watch it please access the webcast via this link: 

    And please excuse the suboptimal audio quality - there were some technical difficulties to work around.

    New version of our Hands-On Lab available for download "Upgrade/Migrate/Consolidate to Oracle 12c" HOL

    Yes! Finally ...

    Roy did all the hard work and patched all our environments with the most recent PSUs. And he managed also to upload our Hands-On Lab not only internally to retriever (Oracle internally) but also to OTN.

    What you'll be able to do?

    • Upgrade an database UPGR to Oracle Database
    • Plug in UPGR into the CDB2, an Oracle Database Container database, and make it a PDB
    • Migrate an database FTEX into another PDB using the Full Transportable Export/Import feature
    • Unplug an Oracle Database PDB and plug it into an Oracle Database container database and finally upgrade it
    • And of course you can play around with the entire environment

    What we've did for your convenience? 

    • Switched to a new PDF viewer which allows better copy&paste - see the instructions document.
      Unfortunately we are not allowed to distribute the relatively old version of Adobe PDF Reader for Linux. 
    • Applied the most recent PSUs to the and homes
    • Fixed some minor things
    • Updated the HOL Instructions
    • Added an "aritificial" environment variable $OH12 to shorten typing
    • And some other tiny little things ...
    • And the lab is packaged with Oracle VBox 5.0.10 including the matching VBox Extensions which caused us trouble with the previous lab environment which was settled on Vbox 4.3 - so we hope that now all will go well.

    Where can you download the lab and the instructions?

    All credits to Roy!!!

    UKOUG Tech 2015 - Summary & Slides

    My first UKOUG Conference is over.

    Actually it was over yesterday already for me as I had to head back to Germany. I would have loved to stay a bit longer and pick more of the many excellent presentations. I visited a few - and all of them were great. It was a tough choice as there were too many interesting things going on at the same time. Only finding the right room was sometimes a bit of a challenge ;-)

    And I would like to have met more and talked to more people. But time was very limited. I didn't see anything from Birmingham except the foot path from the hotel to the venue and return. Plus an excellent Indian restaurant (thanks again to the folks of Pythian for inviting me - that was a wonderful dinner).

    And of course thanks to everybody who attended my 3 talks.

    As promised here are the slides to download:

    Finally a very special Thank You to the organizers of the UKOUG 2015 Conference - it was an excellent event!

    Hope to be back again in 2016!

    VBox 5.0.10 crash issues with our Hands-On-Lab

    Milano - Nov 2015 (c) Mike Dietrich

    I've ran two Hands-On-Workshops with customers and partners in Italy last week in Milano where we used our well known and thousands-of-times proven Hand-On-Lab environment

    But this time some people failed while running the lab with random corruptions either shutting down the entire VM while running - or displaying file corruptions in the spfile - or other issues.

    The common thing in all cases: People had VBox 5.0.10 downloaded and installed right before the workshop.

    Of course they've did it - as I'm tempted too since weeks. Every time I start VBox on my PC Oracle Virtual Box asks me: 

    Even though the screenshot is German you know what it offers me:
    Download and Install Virtual Box 5.0.10.

    Actually the current issue reminds me a lot on what I have experienced in 2014 in an Upgrade Hands-On Workshop in Vienna, Austria. 20 Oracle partners came together for two days for a Hands-On Upgrade/Migrate/Consolidate training. And 6 or 7 had random issues with their Virtual Box images. Corruptions. Failing upgrades at random phases. No patterns.

    Only until somebody figured out via a Google search that at the same time other people started reporting similar behavior with their own VBox images using the brand new version of Virtual Box. It turned out that this newest version of Oracle Virtual Box 4.3 (I think it was 26) had exactly such issues. Everybody else in our room - including myself - running a version a few weeks older had no issues at all.

    When we exchanged the affected installations the next morning replacing it (if I remember correctly: 4.3.24) all went fine for the rest of the workshop.

    I won't say that VBox 5.0.10 is bad as I lack evidence, reproducible test cases, bugs. 

    But I follow other people's Twitter and Facebook messages. And it seems to be that the PERL problem I did report a few days back:

    is not he only issue with VBox images build in version 4 - and now running (more or less) on VBox 5.0.10.

    DOAG Conference 2015 - My Talks

    Guess how I realize that it's just 4 weeks and a bit towards Christmas?

    When DOAG (German Oracle User Group) Conference is happening in my hometown Nürnberg in mid November every year. And this year's DOAG may be my 14th DOAG Conference as far as I remember.

    Really looking forward to is as it is THE SPOT to meet with many German customers, some of them good friends, many many familiar faces, the DOAG leaders who all do a fantastic job - and I'll have the chance to see a lot of great presentations and learn a lot from experts, customers and my dear colleagues.

    Only real downside? I'll have to board a train tomorrow early in the morning to be at the conference center right in time as my two appearance as a speaker will happen tomorrow only: 

    Looking forward to see you there!

    Beijing, Seoul - and OTN Tour Tokyo - just in one week

    Uhhh ... next week will be a tough traveling experience. 19870 km (12347 mi), all in cattle class on 4 different airlines.

    Picture rights remain at The New York Times

    I tried to avoid Lufthansa as they canceled recently flights I heavily relied on - with no reason! And there's still a huge risk of announcing just their 9th strike within a year and a bit.

    But I'm really looking forward to the workshops, to see all the colleagues, customers and of course some great friends. Roy and I will do two internal two-day workshops in Beijing and Seoul with each more than 50 participants - and we'll include a nice hands-on-experience as well. And mid-week I'll head out to Tokyo to present at the DB TECH SHOWCASE 2014 - which is part of the OTN ACE Tour.

    CU soon - thanks!!!

    Utrecht holds the new EMEA record now!
    Plus: Updated Slide Deck

    OMG ... 154 people in an Database Upgrade/Migrate/Consolidate to Oracle Database 12c workshop! That's the EMEA record so far for workshop attendance rates for our workshops in the past 7 years. I'm really impressed. Really!!! And you were such a great audience. I've had plenty of fun, lots of good discussions during the breaks and after the workshop.

    As the auditorium room at the Oracle location in Utrecht fits just 120 people the local marketing folks had the idea of asking Jost if he can stream the workshop to another room. The other option would have been to reject a lot of registered persons. And the streaming went quite well. I've never done this before and I hope it was still ok. But as the other room cross the hallway had daylight windows, fresh air and more space it seemed to be ok for most attendees :-)

    I promissed also a new version of the slide deck - and here it is ready for download. Only 522 slides this time ;-) But I just added two new ones. You may check the log at the end of the deck for recent changes.

    So thanks again - it was my pleasure to spend the day with you. And I hope next time, when I'll ask "Who's live on Oracle Database 12c" that I will see way more fingers going up :-)!!!

    Thanks for coming to the Upgrade Workshops in Dublin & Belfast - special thanks to my friends at LUFTHANSA

    Thanks to everybody who came to our Upgrade/Migrate/Consolidate to Oracle Database 12c on Oct 14/15 in Dublin and Belfast. You were great audiences, I had plenty of fun, excellent deep dive discussion during the breaks and afterwards during the customer visits day on Thursday.

    And very special thanks to my colleagues from Oracle Ireland, especially Mina and Kelly-Marie, but also all the others who were involved in the events and visits and made it happen so smoothly. Everything worked perfectly well except for things not in our hands (such as the massive train delay on the way back from Belfast).

    Just in case you'd like to get the slides I'd recommend to download the deck via this link here:
    Upgrade, Migrate & Consolidate to Oracle Database 12c

    And VERY SVERY PECIAL THANKS to my dear friends at Lufthansa. Mina dropped my off at the airport on Thursday, I wanted to check in and hand over my luggage to the assistant - "Oh sorry, your direct flight to Munich has been canceled". Wonderful news. Dublin must have bad Karma for my travel plans as I've got locked in during the ash cloud some 4.5 years ago. 

    Now my friends at Lufthansa have rebooked me to a very early morning flight for Friday, but with a stopover in Frankfurt (which is not my favorite airport at all). Anyhow, a call with Oracle Travel showed my a flight option that same night with KLM via Amsterdam to Munich. So I called Lufthansa again just finding out that Lufthansa refused to rebook me to that flight. Why? Because the first leg to Amsterdam is operated by Air Lingus - and "Lufthansa has no agreement with Air Lingus".  I told them that I don't care if they have an agreement or not, it's myself getting grounded it Dublin for no reason. But no chance. Even though the lady on the Senator hotline asked her supervisor and his manager (and I really thanked her a lot as she really tried it).

    Simple calculation Lufthansa is doing:

    • Flight costs for the KLM flight to Munich: 730 Euro
    • Total costs for Mike staying another night in Dublin: 100 Euro for the hotel, a few bucks for the dinner and maybe the max fine of 250 Euro (which you can claim back only when you involve a lawyer or a service such as FlightRight). Summing up to a max of 400 Euro. Way cheaper to let him stay another night in Dublin at an airport hotel and make him get up at 4 in the morning to catch the flight to Frankfurt.
    And, to make my experience even more valuable Lufthansa added 45 mins of delay to my leg from FRA to MUC, a flight distance of 35 minutes including take off and landing. I felt so good afterwards, so valued as a customer who flies roughly 5 or 6 times around the globe per year with this airline. 
    Thanks you very much, Lufthansa!!! I made it home on Friday at 12:30pm - instead of 21:45pm on Thursday. Lovely, isn't it?

    Upcoming UPGRADE Workshops in:
    Netherlands, Ireland, Northern Ireland, Spain and Belgium

    Wow ... another OOW is over ... I have returned well but a bit jetlaged on Saturday from San Fransciso. It was a pleasure to meet with so many great customers, partners, Oracle ACEs, geeks and of course colleagues from all over the world.

    And I'm still surprised how little DBAs and managers are aware of the upcoming end of Premier Support for Oracle Database 11.2 and still believe in "The 2nd Release Only". But I'll write something about this later this or next week.

    And as soon as my time allows (most likely in the 2nd half of October) I will publish also the details about how to setup the HOL by yourself as we are not allowed to distribute it because of the patch sets included into it. 

    Anyhow, back in reality (still on vacation today) let me offer you the final seats for the upcoming UPGRADE, MIGRATE & CONSOLIDATE TO ORACLE DATABASE 12c workshops in the following weeks: 

    In case you'll miss links I'll update the blog post as soon as I get them.
