To re-create dropped compatibility roles, use the CREATE ROLE statement and specify the compatibility role name.
Re-creating SYS_AUTH_DBA_ROLE is semantically equivalent to re-creating both the SYS_AUTH_SA_ROLE and SYS_AUTH_SSO_ROLE roles; you cannot re-create these two roles separately.
When you re-create any compatibility role other than SYS_AUTH_DBA_ROLE, administrative privileges on the re-created compatibility role are automatically granted to SYS_AUTH_DBA_ROLE , as long as SYS_AUTH_DBA_ROLE has not been dropped.
