You are administering a multitenant container database (CDB). Identify two ways to access
a pluggable database (PDB) that is open in read-only mode.
A.
as a common user with the set container privilege
B.
by executing the alter session set container command as a local user
C.
by using easy connect
D.
by using the connect statement as a local user having only the set container privilege
E.
by using external authentication
A,D
A,C
You can use the following techniques to connect to a PDB with the SQL*Plus CONNECT command:
Local connection with operating system authentication
Database connection using easy connect
Database connection using a net service name
The following prerequisites must be met:
The user connecting to the PDB must be granted the CREATE SESSION privilege in the PDB.
To connect to a PDB as a user that does not have SYSDBA, SYSOPER, SYSBACKUP, or SYSDG administrative privilege, the PDB must be open. See “Modifying the Open Mode of PDBs” and “Modifying a PDB” for information about changing the open mode of a PDB.
Note:
This section assumes that the user connecting to the PDB is a local user. You can also connect to the PDB as a common user, and you can connect to the root as a common user and switch to the PDB.
