Copy the cross-platform backup sets to the destination system. 5. Copy the Data Pump dump set from the source to the destination system. 6.

Choose the best answer. Examine this configuration: 1. CDB1 is an Oracle Database 12c Release 2 container database (CDB). 2. PDB1 and PDB2 are two pluggable databases (PDBs) in CDB1. After successfully performing all the preupgrade tasks, you execute these commands from the Oracle Database 18c environment: $ export ORACLE_SID=cdb1 $ sqlplus / as sysdba SQL> STARTUP UPGRADE; SQL> SHOW pdbs CON_ID CON_NAME OPEN MODE RESTRICTED --------------------------------------------------------------2 PDB$SEED 3 PDB1 4 PDB2 MIGRATE YES MOUNTED YES MOUNTED YES SQL> ALTER PLUGGABLE DATABASE pdb1 OPEN UPGRADE; Pluggable database altered. SQL> exit $ $ORACLE_HOME/perl/bin/perl catctl.pl -C 'PDB2' What is the outcome?

SQL> SHOW PDBS CON_ID CON_NAME --------------------------------------------------------------------OPEN MODE READ ONLY NO MOUNTED MOUNTED SQL> ALTER PLUGGABLE Pluggable database altered. SQL> ALTER PLUGGABLE DATABASE pdb1 SAVE STATE; Pluggable database altered. SQL> ALTER PLUGGABLE DATABASE pdb1 CLOSE; Pluggable database altered. SQL> ALTER PLUGGABLE A DATABASE pdb2 OPEN; Pluggable database altered. CDB1 is then restarted. Which three are true?
