You want to clone PDB1 and PDB2 into the same CDB. Which statement is correct?
View the current parameter settings shown in the output below.
NAMETYPEVALUE
db_file_multiblock_read_count integer 107
ddl_lock_timeout integer 60
Distributed_lock_timeout integer 60
dml_locks integer 748
lock_sga boolean FALSE
enab1e_dd1_1ogging boolean FALSE
resumable_timeout integer 0
A user logs in to the hrschema and issues the following commands:
SQL > CREATE TABLE emp
(empno NUMBER(3),
enamo VARCHAR2(20),
sal NUMBER (8, 2));
SQL > INSERT INTO emp (empno, ename) VALUES(1, 'JAMES');
At this moment, a second user also logs in to the hrschema and issues the following command:
SQL > ALTER TABLE emp MODIFY salNUMBER(10, 2);
What happens in this scenario?
Several tables are accidentally deleted from a PDB. Which database would you immediately connect to, and as which user, to recover these tables?
Which three statements represent the benefits of multitenant architecture for database consolidation?
By design, you can quickly plug a PDB into a CDB, unplug the PDB from the CDB, and then plug this PDB into a different CDB. The implementation technique for plugging and unplugging is similar to the transportable tablespace technique.
A PDB is a portable collection of schemas, schema objects, and nonschema objects that appears to an Oracle Net client as a non-CDB. All Oracle databases before Oracle Database 12c were non-CDBs.
