SYMPTOMS
When connected from PDB, "FROM ROOT" should be displayed in the LIMIT column of DBA_PROFILES.
CHANGES
None
CAUSE
This is an expected behavior from 12c onwards that the text will be displayed as "FROM ROOT" when connected from PDB.
SOLUTION
From 12c onwards, in Root, query on DBA_PROFILES for this profile and the PASSWORD_VERIFY_FUNCTION should return the Function Name, whereas in PDB will return the text "FROM ROOT".
DBA_PROFILES displays "FROM ROOT" when connected in PDB for common profiles PASSWORD_VERIFY_FUNCTION.
eg:
Create a Common Profile and associate it with a password verification function and then connect with PDB and check the output shown.

defalut是null，所以不同于其他值 default
PDB:
CDB:
上面第一个是default，在cdb下为NULL，在PDB下设置了ORA12C_STIG_VERIFY_FUNCTION，所以不是FROM ROOT.如果CDB/PDB 是相同的就是 FROM ROOT
C##的用户很多还是要在CDB下看，比如account status，pdb下的不准！！
