NEW QUESTION 14
Which three statements are true about Oracle Restart?

A. It can be configured to automatically attempt to restart various components after a hardware or software failure.
B. While starting any components, it automatically attempts to start all dependencies first and in proper order.
C. It can be configured to automatically restart a database in case of normal shutdown of the database instance.
D. It can be used to only start Oracle components.
E. It runs periodic check operations to monitor the health of Oracle component

Answer: ABE

Explanation: A is correct: Oracle Restart improves the availability of your Oracle database. When you install Oracle Restart, various Oracle components can be automatically restarted after a hardware or software
failure or whenever your database host computer restarts E is correct: Oracle Restart runs periodic check operations to monitor the health of these components. If a check operation fails for a component, the component is shut down and restarted. B is also true About Startup Dependencies Oracle Restart ensures that Oracle components are started in the proper order, in accordance with component dependencies. For example, if database files are stored in Oracle ASM disk groups, then before starting the database instance, Oracle Restart ensures that the Oracle ASM instance is started and the required disk groups are mounted. Likewise, if a component must be shut down, Oracle Restart ensures that dependent components are cleanly shut down first. Oracle Restart also manages the weak dependency between database instances and the Oracle Net listener (the listener): When a
database instance is started, Oracle Restart attempts to start the listener. If the listener startup fails, then the database is still started. If the listener later fails, Oracle Restart does not shut down and restart any database instances.

NEW QUESTION 15
In your database, there are tablespaces that were read-only when the last backup was taken. These tablespaces have not been made read/write since then. You want to perform an incomplete recovery on the database by using a backup control file.
What precaution must you take for the read-only tablespaces before performing an incomplete recovery?

A. All the read-only tablespaces should be taken offline.
B. All the read-only tablespaces should be restored separately.
C. All the read-only tablespaces should be renamed to have the MISSINGnnnn format.
D. All the read-only tablespaces should be made online with logging disable

Answer: A

Explanation: Take data files from read-only tablespaces offline before doing recovery with a backup control file, and then bring the files online at the end of media recovery. http://docs.oracle.com/cd/E11882_01/backup.112/e10642/osadvsce.htm#BRADV227

B. available archived redo log files
C. backup sets and image copies that are obsolete

log, or control file -Backups that have expired -Backups restricted by time, path name, device type, tag, or recoverability -Archived redo log files and disk copies http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmreprt.htm#BRADV89585
