Lets suppose that you had a "crash test dummy" environment that you want to give to "new DBAs" to try to maintain... as a training exercise, of course.
What types of things would you do to it to help them "learn on the job"?
For simplicity, let's limit it to non-RAC environments
Obviously, you really don't want to run this in any environment used for Business including the Development server(s).
Some ideas I have
- zero out a few data blocks. (w/o Active Data Guard.)
- infinite loop that does pDML inside of DPE
- remove a hard drive (try the one used to mount "/" )
- hide your MP3 collection on the FRA LUN (in a ".hidden" folder)
Please share your "excellent" ideas
