NEW QUESTION 7
Which four are true about duplicating a database using Recovery Manager (RMAN)? (Choose four.)

  • A. Duplication can be done by having the auxiliary databaseinstance pull backup sets from the target database instance.
  • B. A connection to an auxiliary instance is always required.
  • C. A subset of the target database can be duplicated.
  • D. A new DBID is always created for the duplicated database.
  • E. A connection tothe recovery catalog instance is always required.
  • F. A backup of the target database is always required.
  • G. Duplication can be done by having the target database instance push copies to the auxiliary database instance.
  • H. A connection to the target database instance is always required.

Answer: ABCG

Explanation:
A duplicate database is a copy of your target database. With the FOR STANDBY clause, it keeps the same unique database identifier(DBID); If FOR STANDBY not specified it creates a new DBID. The duplicate database can include the same content or only a subset from the source database. It can be in the same host or a separate host. The principal work of the duplication is performed by the auxiliary channels.These channels correspond to a server session on the auxiliary instance on the destination host for backup based duplication. For active database duplication the target channels perform the work of pushing data file copies to the auxiliary instance (if number of allocated target channels is greater than the number of allocated auxiliary channels).

NEW QUESTION 8

  • C. RMAN “pushes” the backups of the database to be duplicated over the network to the auxiliary instance.
  • D. The NOREDO clause can be used if the backups of the database being duplicated were taken when the database wasin ARCHIVELOG mode.
  • E. RMAN SBT-based backups of the database to be duplicated can be used by the auxiliary instance.
  • F. The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is closed.
  • G. The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is opened.
  • H. RMAN disk-based backups of the database to be duplicated can be used by the auxiliary instance.

NEW QUESTION 18
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.
