Why do the Harvard researchers use scientific technology in the experiments？A．Because they

A. You can use RMAN stored scripts

B. Recovery is faster if data is stored in catalog in addition to the control file

C. You can store backup information of all registered databases in one place

D. Database backups are automatically deleted when they are older than the specified time period

You are using a recovery catalog to maintain Recovery Manager (RMAN) backup information for yourproduction database. You have registered your production database and are performing regular backups.Because of a new requirement you have added a few new tablespaces to your production database and youwant them to be included in backups.Identify two options for completing this task. （）(Choose two.)

A. Reregistering the target database in recovery catalog

B. Transporting the new tablespaces to the recovery catalog database

C. Syncronizing the recovery catalog with the target database control file

D. Performing a fresh backup of the target database to include the new data files in the catalog database

tabase is running out of space and you do not have options to increase the space. However, you have another database where more space is available and you want to move your existing recovery catalog to this database.The options that can be considered while moving the recovery catalog are as follows:（）1. Using one of the Oracle expdp utilities to export the catalog data2. Creating a recovery catalog user and granting the necessary privileges in the other database3. Creating the recovery catalog using the CREATE CATALOG command4. Using the corresponding impdp utility to import the catalog data into the other database5. Registering the target database in the new catalog database using the REGISTER DATABASE command Identify the option with the correct sequence for moving the recovery catalog.

A. 2, 3, 5

B. 1, 2, 4

C. 1, 2, 4, 5

D. 1, 2, 3, 4, 5

A. stored scripts in the recovery catalog

B. backups that can be deleted from disk

C. backup sets and image copies are obsolete

D. backups that do not have the AVAILABLE status in the RMAN repository RMAN

You are using recovery Manager (RMAN) with a recovery catalog to backup up your production database. The backups and the archived redo log files are copied to a tape drive on a daily basis. The database was open and transactions were recorded in the redo logs. Because of fire in the building you lost your servers having the production database and the recovery catalog database.The archive log files generated after the last backup are intact on one of the remote locations.While performing a disaster recovery of the production database what is the next step that you must perform after restoring the data files and applying archived redo logs？（）

A. Open the database in NORMAL mode

B. Open the database in read-only mode

C. Open the database in RESTRICTED mode

D. Open the database with the RESETLOGS option

You want to create the Recovery Manager (RMAN) Virtual Private Catalog (VPC) to maintain a separation of responsibilities along with a consolidation of RMAN repository.Which condition must be met before you create the VPC？（）

A. A base catalog exists

B. The recovery catalog is empty

C. The base recovery catalog must be dropped

D. A target database is registered in the recovery catalog

You are using Recovery Manager (RMAN) with a recovery catalog to back up your production database. Thebackups and the archived redo log files are copied to a tape drive on a daily basis.Because of media failure,you lost your production database completely along with the recovery catalog database.You want to recover the target database and make it functional. You consider performing the following steps to accomplish the task:1) Restore an autobackup of the server parameter file.2) Restore the control file3) Start the target database instance4) Mount the database5) Restore the data files6) Open the database with RESETLOGS option7) Recover the data files8) Set DBID for the target databaseWhich option illustrates the correct sequence that you must use？（）

A.8，1，3，2，4，5，7，6

B.1，8，3，4，2，5，7，6

C.1，3，4，2，8，5，6，7

D.1，3，2，4，6，5，7，8
