NEW QUESTION 16
Which two are trueabout changing the LOCAL_UNDO_ENABLED property to false in a CDB? (Choose two.)

• A. After the change, only a common user with the required privilege can create an undo tablespace in CDB&ROOT.
• B. Any new PDB and existing PDBs are automatically configured to use the default undo tablespace in CDB$ROOT.
• C. After the change, only one undo tablespace can exist in CDB$ROOT.
• D. After the change, any user with the required privilege can create an undo tablespace in the PDBs.
• E. Undo tablespaces existing in PDBs must be dropped before the change.
• F. After the change, each existing PDB has to be reopened for the new undo mode to take effect.

Answer: BC

Explanation:
You can set a CDB in local UNDO mode either at CDB creation or by altering the CDB property. When the database property LOCAL_UNDO_ENABLE is FALSE, which is the default, there is only one UNDO tablespace that is created in the CDB root, and that is shared by all containers. When LOCAL_UNDO_ENABLE is TRUE, every container in the CDB uses local undo and each PDB must have its own local UNDO tablespace. To maintain ease of management and provisioning, UNDO tablespace creation happens automatically and does not require any action from the user. When a PDB is opened and an UNDO tablespace is not available, its automatically created.

NEW QUESTION 20
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 can be purged manually from the alert history.
• C. Stateless alerts can be cleared manually.
• D. Stateless alerts are automatically cleared.
• E. Stateful alerts are purged automatically from the alert history.

Answer: BC

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.
