  2. The log switch hangs occur for transactions until free space is available in the flash recovery area

  3. The Oracle database server deletes a file that is on the obsolete file list to make free space in the flash recovery area

  4. The database instance status is implicitly changed to RESTRICTED mode and file creations to the flash recovery area are prevented

Answer: B,C

Ensurepass 2018 PDF and VCE

Which statement is true about the block corruption detected by the command? Exhibit:

  1. No action is taken except the output in the Exhibit.

  2. The ADVISE FAILURE command is automatically called to display the repair script.

  3. The failure is logged into the Automatic Diagnostic Repository (ADR).

  4. The corruption is repaired by the command implicitly.

Answer: C Explanation:

Detection of Block Corruption (link)

Oracle Database supports different techniques for detecting, repairing, and monitoring block corruption. The technique depends on whether the corruption is interblock corruption or intrablock corruption. In intrablock corruption, the corruption occurs within the block itself. This corruption can be either physical or logical. In aninterblock corruption, the corruption occurs between blocks and can only be logical.

For example, the V$DATABASE_BLOCK_CORRUPTION view records intrablock corruptions, while the Automatic Diagnostic Repository (ADR) tracks all types of corruptions. Table 16-1 summarizes how the database treats different types of block corruption.

Question No: 117 – (Topic 2)

What command would you use to ensure that backup records in the control file are pointing to actual physical files on the backup media?

  1. crosscheck

  2. list backup

  3. confirm

  4. resync

  5. backup validate

Answer: A Explanation: Crosscheck

A check to determine whether files on disk or in the media management catalog correspond to the data in the RMAN repository. Because the media manager can mark tapes as expired or unusable, and because files can be deleted from disk or otherwise become corrupted, the RMAN repository can contain outdated information about backups. Run the CROSSCHECK command to perform a crosscheck.

The quot;control filequot; in the QUESTION NO: is acting as the RMAN repository if the RMAN use control file store metadata.

Topic 3, Using the RMAN Recovery Catalog (RC)

Question No: 118 – (Topic 3)

What RMAN command must you use before you can back up a database using the recovery catalog?

  1. create catalog

  2. install database

  3. catalog database

  4. merge Catalog with database

  5. register database

Answer: E

Question No: 119 – (Topic 3)

You have created a script in the recovery catalog called backup_database. Which of the following commands would successfully execute that script?

Ensurepass 2018 PDF and VCE

  1. Option A

  2. Option B

  3. Option C

  4. Option D

  5. Option E

Answer: D Explanation:

Use the EXECUTE SCRIPT command to run a stored script. If GLOBAL is specified, then a

global script with this name must exist in the recovery catalog; otherwise, RMAN returns error RMAN-06004. If GLOBAL is not specified, then RMAN searches for a local stored script defined for the current target database. If no local script with this name is found, then RMAN searches for a global script by the same name and executes it if one is found.
