Which three statements are true about the startup and shutdown of multitenant container databases (CDBs) and pluggable databases (PDBs)?
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.
Consider the following scenario for your database:
-Backup optimization is enabled in RMAN.
-The recovery window is set to seven days in RMAN.
-The most recent backup to disk for the tools tablespace was taken on March 1, 2015.
-The tools tablespace is read-only since March 2, 2015.
On March 15, 2015, you issue the RMAN command to back up the database via the Media Manager Interface.
Which statement is true about the backup of the tools tablespace?
Which three requirements must be met before a tablespace can be transported across different platforms?
You created a tablespace with this statement:
