Note the output of the following query;
SQL> SELECT flashback_archieve_name, status FROM dba_flashback_archieve; FLASHBACK_ARCHIEVE_NAME STATUS
You executed the following command to enable Flashback Data Archive on the EXCHANGB_PATE table:
ALTER TABLE exchange_rate FLASHBACK ARCHIEVE;
What is the outcome of this command?
A. The table uses the default Flashback Data Archive.
B. The Flashback Data Archive Is created In the SYSAUX tablespace.
C. The Flashback Data Archive is created in the same tablespace where the tables are stored.
D. The command generates an error because no flashback Data Archive name is specified and there is
no default Flashback Data Achieve.
A database is running In ARCHIVBXXMS mode. It has two online redo log groups and each group has one member.
A LGWR Input/output (I/O) fells due to permanent media failure that has resulted In the loss of redo log file and the LWGR terminates causing the instance to crash.
The steps to recover from the loss of a current redo log group member in the random order are as follow.
1) Restore the corrupted redo log group.
2) Restore from a whole database backup.
3) Perform incomplete recovery.
4) Relocate by renaming the member of the damaged online redo log group to a new location.
5) Open the database with the RESETLOGS option.
6) Restart the database instance.
7) Issue a checkpoint and clear the log.
Identify the option with the correct sequential steps to accomplish the task efficiently.
A. 1, 3, 4, and 5
B. 7, 3, 4. and 5
C. 2, 3, 4, and 5
D. 7, 4, 3. and 5
E. Only 6 is required
Recovering After Losing All Members of an Online Redo Log Group
If a media failure damages all members of an online redo log group, then different scenarios can occur depending on the type of online redo log group affected by the failure and the archiving mode of the database.
If the damaged online redo log group is current and active, then it is needed for crash recovery; otherwise, it is not. Table 30-4 outlines the various recovery scenarios.
Identity two advantages of using a recovery catalog in-load of the control File of the target database Recovery Manager (RMAN). (Choose two.)
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 Recovery Manager (RMAN) with a recovery catalog to back up your production database. The backups 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 could consider performing the following steps to accomplish this task:
1) Restore an autobackup of the server parameter file.
2) Restore the control file.
3) Start the target database Instance.
4) Mount the database.
5) Restore the data files.
6) Open the database with the RESETLOGS option.
7) Recover the data files.
8) Set DBID for the target database
Which 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
You configured the default backup device type as disk for RMAN backups. In your database, because of business requirements, you have to take a simultaneous duplicate backup of the data files when the RMAN BACKUP command is used.
What must you set using the RMAN CONFIGURE command to achieve this?
A. MAXSETSIZE TO 2;
B. DEVICE TYPE DISK PARALLELISM 2;
C. RETENTION POLICY TO REDUNDANCY 2;
D. DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
Examine the following ALTER command;
SQL> ALTER DISKGROUP dgroup1 UNDROP DISKS;
What is the purpose of the command?
A. It cancels all pending disk drops within the disk group.
B. It adds previously dropped disks back into the disk group.
C. It restores disks that are being dropped as the result of a DROP DISKGROUP operation.
D. It mounts disks in the disk group for which the drop-disk operation has already been completed.
E. It restores all the dropped disks in the disk group for which the drop-disk operation has already
Your database is running In ARCIIIVELOG mode. One of the data files, USBRDATAOI. DBF, in the users tablespace is damaged and you need to recover the file until the point of failure. The backup for the data file is available.
Which three files would be used in the user-managed recovery process performed by the database administrator (DBA)? (Choose three.)
A. redo logs
B. control file
C. temporary files of temporary tablespace
D. the latest backup of only the damaged data file
E. the latest backup of all the data files In the USERS tablespace
You want to set the following Initialization parameters for your database Instance
LOG_ARCHIVE_DEBT_1 = ,,LOCATION=/disk1/arch
LOG_ARCHIVE_DBST_2 = ,,LOCATION=/disk2/arch
LOC_ARCHIVB DBST_3 = ,,LOCATION=/disk3/arch
LOG_ARCHIVE DBST_ = ,,LOCATION=/disk3/arch
Identify the statement that correctly describes this setting.
A. The MANDATORY location must be a flash recovery area.
B. The optional destinations may not use the flash recovery area.
C. This setting is not allowed because the first destination is not set as MANDATORY.
D. The online redo log file is not allowed to be overwritten if the archived log cannot be created in the
Specifies that filled online log files must be successfully archived to the destination before they can be reused.
If MANDATORY is not specified, then, by default, the destination is considered to be optional.
At least one destination must succeed, even if all destinations are optional. If archiving to an optional destination fails, the online redo log file is still available for reuse and may be overwritten eventually. However, if the archival operation of a mandatory destination fails, online redo log files cannot be overwritten.
Which of the following cannot be used as input to the SQL Tuning Advisor? (Choose all that apply.)
A. A single SQL statement provided by a user
B. An existing SQL Tuning Set (STS)
C. A preprocessed Database Replay workload
D. A schema name
E. SQL statement identified in EM as using excessive resources
You executed the following command in Recovery Manager (RMAN):
RMAN> REPORT NEED BACKUP days 3;
What is the output of this command?
A. a list of files that require a backup within three days
B. a list of files requiring more than 3 days of archive logs to apply
C. a list of files that RMAN recommends be backed up only once in every three days, based on low volatility
D. a list of files for which a backup has already been performed in the last three days and which is required
to be backed up again based on the high number of transactions performed on them
