Question 5: You conned using SQL Plus to the root container of a multitenant container database (CDB)with SYSDBA privilege.
The CDB has several pluggable databases (PDBs) open in the read/write mode.
There are ongoing transactions in both the CDB and PDBs.
What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?
A. The shutdown proceeds immediately. The shutdown proceeds as soon as all transactions in the
PDBs are either committed or rolled hack.
B. The shutdown proceeds as soon as all transactions in the CDB are either committed or rolled back.
C. The statement results in an error because there are open PDBs.
D. The shutdown proceeds as soon as all transactions in both the CDB and PDBs are either
committed or rolled back.
Correct Answer: B
Explanation
* SHUTDOWN [ABORT | IMMEDIATE | NORMAL | TRANSACTIONAL [LOCAL]]
Shuts down a currently running Oracle Database instance, optionally closing and dismounting a
database. If the current database is a pluggable database, only the pluggable database is closed. The
consolidated instance continues to run.
Shutdown commands that wait for current calls to complete or users to disconnect such as
SHUTDOWN NORMAL and SHUTDOWN TRANSACTIONAL have a time limit that the SHUTDOWN
command will wait. If all events blocking the shutdown have not occurred within the time limit, the
shutdown command cancels with the following message:
ORA-01013: user requested cancel of current operation
* If logged into a CDB, shutdown closes the CDB instance.
To shutdown a CDB or non CDB, you must be connected to the CDB or non CDB instance that you
want to close, and then enter SHUTDOWN Database closed.
Database dismounted.
Oracle instance shut down.
To shutdown a PDB, you must log into the PDB to issue the SHUTDOWN command.
SHUTDOWN
Pluggable Database closed.
Note:
* Prerequisites for PDB Shutdown
When the current container is a pluggable database (PDB), the SHUTDOWN command can only be
used if:
The current user has SYSDBA, SYSOPER, SYSBACKUP, or SYSDG system privilege.
The privilege is either commonly granted or locally granted in the PDB.
The current user exercises the privilege using AS SYSDBA, AS SYSOPER, AS SYSBACKUP, or AS SYSDG at
connect time.
To close a PDB, the PDB must be open.
