Hi Erik,

I can tell you from first hand experience, that if you use VirtualBox 5.0,
the perl that's packaged with 12.1.0.2 will break. (Core dumps) The fix
is to download perl-5.14.1 from CPAN and compile from source. Once you do
that, it works fine.

Generally I have used the latest VBox 4.x, and OL6.x, the directions work
fine.
Don't use OL7, but vbox 5 should mostly be OK, I have not do it with vbox
5 yet,. but have a Solaris version working on that release with no issues.

So, I'm going to be leading a RAC Attack event in November, so, I thought
I'd better get up to speed with the latest versions of VirtualBox, OL, and
Oracle. I've done a RAC Attack setup a couple of times before, but it's
been a year or more.

Thanks for those providing those notes! We are having a RAC Attack event
in Chicago in a few weeks and I plan to get started on the installs this
weekend so I'm sure this will help.

Mark and Alfredo - could you list your events athttp://racattack.org/events ?
One of the best things about this list
is that you can see who has recently run events. Ludovico, Erik and
Bobby have all run recent events and Markus Flechtner has one
scheduled two weeks from now in Germany.

Ludovico, Erik, Bobby and Markus: what versions of Enterprise Linux
and VirtualBox have you used? Website says EL 6.4 and VirtualBox
4.2.12 to 4.2.18 (software components page). Have you guys already
used newer version of EL and VirtualBox? We might want to wait and
tackle RH7 and database 12.2 at the same. (I have no inside knowledge
about 12.2 but 161818.1 says that 12.1.0.2 is terminal so 12.2 must be
coming next.)

FYI, all my recent testing was VirtualBox 5.0, OL 6.7, and Oracle 12.1.0.2.

Mark, thanks for testing virtualbox 5! for the most stable
experience, stick with the tested version for your class. to join the
ranks of racattack legends, use virtualbox5 in your classes - and make
sure to incorporate any lessons learned back into the wikibook! it's
very easy to edit the pages, don't be afraid. :) virtualbox5 is
definitely important to get on top of and your notes already provide a
great starting point. Alvaro if you have time to verify Mark's notes
then you two could probably start updating the official wiki
instructions.

one idea would be to initially put the virtualbox 5 differences in
infoboxes or something, then move them to the main text after they've
been tested by a few classes. just to make sure that the wiki remains
somewhat stable as we update it, since people all over the world are
using these lab instructions to run rac attack workshops.
