AutoUpgrade in trouble when you are short on RAM

Actually I blog about this topic for the simple reason that currently you won’t find helpful information in MyOracle Support. And I’ve seen this issue now twice in a row at Enterprise customers.

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

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 …
