Re: randomize_va_space

I just checked our Exadata and ODA installations, including a newly-installed Cloud_at_Customer environment, and they all have *kernel.randomize_va_space* set to 2. It's definitely not a setting we've modified, so that's part of their stock configuration. All of our Oracle databases are 19c.
