This document describes instance parameters that cannot be modified due to instance specification limits and their required values.
Notes
Setting the following parameters will use system resources. To prevent the database use from being affected by parameter values, configure them as needed.
Note: 
Some are key parameters, and changing them may affect your use or the normal running of the instance. Therefore, exercise caution when modifying key parameters.
