Question # 31

Which two statements are true about this common user?

SQL > conn c##usr/pwd@pdb1

You are connected to PDB1 successfully.

SQL > conn c##usr/pwd@pdb2

You are connected to PDB2 successfully.

SQL > conn c##usr/pwd@pdb2

You are unable to create a connection. You first need to sync PDB2 by executing:

SQL > conn / as sysdba

SQL > exec DBMS_PDB.SYNC_PDB;

SQL > conn c##usr/pwd@pdb2

You are unable to create a connection. You need to create the common user c# #usr explicitly in PDB2 by executing:

SQL > conn system/pwd@pdb2

SQL > CREATE USER c##usrIDENTIFIED BYpwd CONTAINER=CURRENT;

Now you are able to connect as common user c##usr to PDB2.
