You must unload data from the orders, order_items, and products database tables to four files using the External Tables.
CREATE TABLE orders_ext
(order_id, order_date, product_id, product_name,quantity)
ORGANIZATION EXTERNAL
(
TYPE ORACLE_DATAPUMP
DEFAULT DIRECTORY ext.dir
LOCATION ('ordersl.dmp','orders2.dmp','orders3.dmp','lorders4.dmp')
)
PARALLEL
AS
SELECT o.order_id,o.order_date,p.product_id,p.product_name,i.quantity
FROM orders o,productsp,order_items
WHERE o.orderid = i.order_id and i.product_id = p.product_id;
You execute the command shown in the Exhibit, but only two files are created. Which parameter must be changed so that four files are created?

You want to migrate your Oracle 11g database as a pluggable database (PDB) in a multitenant container database (CDB).
Examine the steps required to perform the migration:
1. Use Data Pump export to perform a full transportable export on the source database with the export parameter VERSION=12.
2. Place all tablespaces in read-only mode on the source database.
3. Upgrade the source database to Oracle Database 12c.
4. Copy the dump file and data files to the desired location in the target database.
5. Create a new PDB in the target CDB.
6. Synchronize the PDB on the target CDB.
7. Use Data Pump import on the new PDB by using the full transportable import options.
Identify the required steps in the correct order.

Examine the steps to configure Oracle Secure Backup (OSB) for use with RMAN:
1. Create media families for data files and archived redo log files.
2. Configure database backup storage selectors or RMAN media management parameters.
3. Create an OSB user preauthorized for RMAN operations.
4. Configure RMAN Access to the OSB SBT.
5. Disable Non-Uniform Memory Access (NUMA) awareness by setting the ob_ignore_numa parameter to 0.

In your database, there are tablespaces that were read-only when the last backup was taken. These tablespaces have not been made read/write since then. You want to perform an incomplete recovery on the database by using a backup control file.
What precaution must you take for the read-only tablespaces before performing an incomplete recovery?

Your Oracle 12c multitenant container database (CDB) contains multiple pluggable databases (PDBs).
In PDB HR_PDB, common user C##ADMIN and local user B_ADMIN have only the CONNECT privilege.
You create a common role C##ROLE1 with the CREATE ANY TABLE and SELECT ANY TABLE privileges.
You then execute the commands:
SQL> GRANT c##role1 TO c##admin CONTAINER=ALL>;
SQL> CONN sys/oracle@HR_PDB as sysdba
SQL> GRANT c##role1 TO b_admin CONTAINER=CURRENT;
Which three statements are true? (Choose three.)
