Oracle internal roles - DBA_ROLES
DB: Oracle Enterprise Edition 12.1.0.2.0
OS: OEL 7
RAC: 3 Nodes
In our Oracle RAC database, there are 187 roles (SELECT * FROM DBA_ROLES).
What is the best query to figure out / separate ALL Oracle internal roles that were create by Oracle during installation/patches,etc. and roles created by DBAs?
Note: Most of the roles I could figure out but some I am not sure.
Thank you
Jack
