VBox 5.0.10/12 issues with PERL and Seg Faults – UPDATE

A bit more than two months ago I did hear from several people having issues with our Hands-On Lab environment. And it became clear that only those who use Oracle Virtual Box 5 see such errors.

Then I read Danny Bryant‘s blog post (thanks to Deiby Gomez for pointing me to it) about similar issues and a potential solution yesterday:

And interestingly one of my colleagues, our PL/SQL product manager Bryn Llewellyn started an email thread and a test internally yesterday as well.

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 …

Oracle VirtualBox 5.0.x – Segmentation Fault in PERL

Please see as well:


 

Yesterday and the day before I’ve exchanged several emails with Ana who downloaded our Hands-On-Lab from here:

after OOW15, encountering a SEGMENTATION FAULT when trying to start the database upgrade with catctl.pl:

$ $ORACLE_HOME/perl/bin/perl catctl.pl catupgrd.sql

Segmentation fault 

Very strange thing … 

The database is in upgrade mode (checked this in the alert.log) and there are no strange things mentioned anywhere. Plus hundreds of people have run and completed our lab so far.

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 …

Is Oracle certified to run on VMWare?

This question in similar occurences gets asked during every Upgrade Workshop at least once. People would like to know if they can run an Oracle Database or Oracle Real Application Clusters or Oracle Grid Control or Oracle Fusion Middleware or … in an VM environment with VMWare’s virtualisation products.

And the answer is: Yes, you can!!
But … there’s a fine print you should take care on before setting up virtual environments with a different solution than XEN based Oracle VM.
