This article shows you what are the unarchived hidden parameters in the Oracle12c version, which are concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.
I will list all the unrecorded parameters in Oracle 12.1.0.1c. The following is a query to view all parameters (recorded and unrecorded) that contain the string entered when prompted:
