@dploeger Your code is currently failing a syntax check, other than that the change looks good to me.

Offenses:
spec/defines/oracle_spec.rb:186:13: C: Layout/IndentHash: Use 2 spaces for indentation in a hash, relative to the start of the line where the left curly brace is.
            ensure: 'present',
            ^^^^^^^^^^^^^^^^^
