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.

OOW 2015 Sessions and Labs - Oracle Open World

OOW 2015OMG ... only a few weeks to go ... Oracle Open World 2015 in San Francisco is coming closer and closer ...

And this year will be really tough as we have a reduced number of people there - but more work to do as in previous years. 3 talks (2 for Upgrade, 1 for Data Pump), 4 labs (all in Nikko Hotel 15min walking distance from Moscone Center) - plus a good number of customer meetings already lined up. Plus the chance to meet so many great people ... and not to forget the Data Warehouse Global Leaders event at the Oracle HQ. 

I have that strange feeling that I will be VERY tired when I'll board the plane on Friday night heading back to Germany ... ;-)

VBOX Hands-on-Lab image - build your own :-)

Oh ... I know ... I promised to post all the details how I've build up our pretty straight forward Hands-On-Lab Roy, Carol, Cindy, Joe and I used at OOW and some other occasions to let you upgrade, migrate and consolidate databases to Oracle Database 12c and into Oracle Multitenant.

And well, some have emailed me already ... and I had this feeling that my schedule will be very tight after OOW. Even right now (Sunday evening) I'm already back at my second home, Lufthansa Senator Lounge at Munich Airport. Waiting for my flight to Rome in an hour or so. Honestly speaking I had really no time in the past weeks to sit down for 2 hours to write down all the steps to guide you through the rebuild. And I didn't want to throw just a few nuggets - my intention is always to get you detailed steps which really work and don't miss anything.

But I have very good news for all who are waiting for the HOL Image :-)
Roy is working hard (and I'm confident that he'll succeed) to get the image published on OTN within the next weeks. So please stay tuned. Even with the Christmas holidays coming up I'm tied into a schedule to visit Rome, Torino, Milan, Brussels, assist some customers in their final go-live-phase for Oracle Database 12c - and I'm really looking forward to that vacation.

Stay tuned - and thanks again for your patience :-)

Mile High ... Collaborate 2013 in Denver

Collaborate 2013 is almost over - we are running our final Hands-On-Lab session right now in the Convention Center in Denver, Colorado. For those seeking for the Hands-On-Lab Instructions for our session please be patient until Oracle Database 12c gets released. As soon as this happens we'll offer you the HOL Instructions plus many more information about Oracle Database 12c and the different upgrade and migration paths.

Denver apparently has become my no.3 US city - not only because the mountains are so close by. But the city itself is really worth a visit :-) Please find some impressions below :-) And see you next year at Collaborate 2014 on April 7-11 in Las Vegas.


Yes, again SNOW in Denver ... well ...
