Which two are true about creating RMAN backups for an Oracle container database? (Choose two.)
- A. Online Redo Log backups can be created while connected to the root container.
- B. Control file backups can be created while connected to a nonroot container.
- C. Archived Redo Log backups can be created while connected to an application root CDB.
- D. Control file backups can be created while connected to the root container.
- E. The BACKUP TABLESPACEcommand can back up a PDBtablespace even if RMAN is connected to CDB$ROOT.
Answer: D,E
Explanation:
A - FALSE. The ARCH process backs up online redo logs (by creating Arch redo logs), never the DBA. DBAs backup Archive Redo Logs, not online redo logs.
B - TRUE. Control files are DB wide - backing them up, from the Container Root, is exactly where you do this.
C - TRUE. Part of the point of Multitenant is that you have control of all PDBs from the CDB level.
D - FALSE. An application root container is still below the main Container, so you cannot administer control files from here.
E - FALSE. For the same reason as above, you can only create control file backups from the Root Container.

F - FALSE. An online backup is INCONSISTENT.
NEW QUESTION # 16
Which two are true about server-generated alerts? (Choose two.)
- A. Stateful alerts must be created by a DBA after resolving the problem.
- B. Stateless alerts are automatically cleared.
- C. Stateful alerts are purged automatically from the alert history.
- D. Stateless alerts can be purged manually from the alert history.
- E. Stateless alerts can be cleared manually.
Answer: D,E
Explanation:
Explanation
Except for the tablespace space usage metric, which is database related, the other metrics are instance related.
Threshold alerts are also referred to as stateful alerts which are automatically cleared when an alert condition clears. Stateful alert appears in DBA_OUTSTANDING_ALERTS and when cleared go to DBA_ALERT_HISTORY. Other server-generated alerts correspond to specific database events such as ORA-* errors, "Snapshot too old" errors, Recovery Area Low on Free Space, Resumable Session Suspended.
These are non threshold based alerts, also referred to as stateless alerts. Stateless alerts go directly to the History table. +++ Most alerts (such as "Out of Space") are cleared automatically when the cause of the problem disappears. However, other alerts (such as generic alert log errors) are sent to you for notification and must be acknowledged by you. After taking the corrective measures, you acknowledge an alert by clearing or purging it. Clearing an alert sends the alert to the Alert History which is accessible from Monitoring sub menu.
Purging an alert removes it from the Alert History.
