Examine the commands:
SQL> ALTER SESSION SET RECYCLEBIN = ON;
Session altered.
SQL> DROP TABLE emp; --(First EMP table) Total dropped.
SQL> CREATE TABLE emp(id NUMBER CONSTRAINT emp_id_idx PRIMARY KEY, name VARCHAR2 (15), salary NUMBER(7,2));
Table created.
You then execute multiple INSERT statements to insert rows into EMP table and drop the table again: SQL> DROP TABLE emp; -- (Second EMP table)
Table dropped.
SQL> FLASHBACK TABLE emp TO BEFORE DROP;
Which statement is true about the FLASHBACK command?

Examine the steps/operations performed during the RMAN backup operation by using Oracle Secure Backup (OSB):
1. Start the RMAN client by using the RMAN TARGET / command.
2. Start the RMAN client by using the OSB user.
3. RMAN creates the backup pieces.
4. Run the RMAN BACKUP command with the SBT channels.
5. OSB creates a backup job and assigns a unique identifier.
6. OSB creates a backup job request through the OSB SBT library.
7. OSB stores metadata about RMAN backup pieces in the OSB catalog.
8. OSB starts the backup operation.
9. OSB updates the RMAN catalog.
Identify the required steps/operations performed in correct order.
Correct Answer:C

Examine the list of possible steps to transport a tablespace across platforms that have the same compatibility level, character sets, and endian format:
1. Make the tablespace read-only at the source database.
2. Export metadata from the source database.
3. Import metadata into the target database.
4. Transfer the dump file and data files to the target machine.
5. Convert data files by using Recovery Manager (RMAN).
6. Make the tablespace read-write at the target database. Identify the required steps in the correct order.
Correct Answer:D
Step 1 (1): To copy tablespaces from one database to another using transportable tablespace, the source tablespaces are first kept in READ-ONLY mode (to ensure data consistency). Once the tablespaces are in READ-ONLY mode, the actual datafiles belonging to the source tablespaces are copied from source database to target database (using any available methods like scp, sftp, rcp, etc).
Step 2 (2): Once the tablespace is kept in READ-ONLY mode, we need to generate the metadata export of the tablespaces that needs to transported using the DataPump export utility.
Step 3 (4): Once the metadata export is generated on the source database for all the tablespaces that needs to be transported, we need to copy the Export Dump file as well as all the datafiles belonging to the tablespaces to be transported to the target database server.
