NEW QUESTION 13
You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure.
In which three ways can you re-create the lost disk group and restore the data? (Choose three.)

  • A. Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.
  • B. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.
  • C. Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.
  • D. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.
  • E. Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.
  • F. Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.

Answer: ACF

Explanation: AC (not E):
The md_restore command allows you to restore a disk group from the metadata created by the md_backup command. md_restore can’t restore data, only metadata.

NEW QUESTION 14
One of your databases supports an OLTP workload. The default UNDO tablespace is fixed size with:

  • E. A committed update to the SALES table was made more than 12 minutes before the query began
  • F. An uncommitted delete to the SALES table was made more than 12 minutes before the query began
  • G. An update was made to the SALES table before the query began

NEW QUESTION 15
Which three statements are true concerning the multitenant architecture? (Choose three.)

  • A. Each pluggable database (PDB) has its own set of background processes.
  • B. A PDB can have a private temp tablespace.
  • C. PDBs can share the sysaux tablespace.
  • D. Log switches occur only at the multitenant container database (CDB) level.
  • E. Different PDBs can have different default block sizes.
  • F. PDBs share a common system tablespace.
  • G. Instance recovery is always performed at the CDB level.

Answer: BDG

Explanation: B:
* A PDB would have its SYSTEM, SYSAUX, TEMP tablespaces. It can also contains other user created tablespaces in it.
* There is one default temporary tablespace for the entire CDB. However, you can create additional temporary tablespaces in individual PDBs.
D:
* There is a single redo log and a single control file for an entire CDB
* A log switch is the point at which the database stops writing to one redo log file and begins writing to another. Normally, a log switch occurs when the current redo log file is completely filled and writing must continue to the next redo log file.
G: instance recovery
The automatic application of redo log records to uncommitted data blocks when an database instance is restarted after a failure.
Incorrect: Not A:
* There is one set of background processes shared by the root and all PDBs.
* High consolidation density. The many pluggable databases in a single container database share its memory and background processes, letting you operate many more pluggable databases on a particular platform than you can single databases that use the old architecture.
Not C: There is a separate SYSAUX tablespace for the root and for each PDB. Not F: There is a separate SYSTEM tablespace for the root and for each PDB.

NEW QUESTION 16

NEW QUESTION 17
You are required to migrate your 11.2.0.3 database as a pluggable database (PDB) to a multitenant container database (CDB).
The following are the possible steps to accomplish this task:
1. Place all the user-defined tablespace in read-only mode on the source database.
2. Upgrade the source database to a 12c version.
3. Create a new PDB in the target container database.
4. Perform a full transportable export on the source database with the VERSION parameter set to 12 using the expdp utility.
5. Copy the associated data files and export the dump file to the desired location in the target database.
6. Invoke the Data Pump import utility on the new PDB database as a user with the DATAPUMP_IMP_FULL_DATABASE role and specify the full transportable import options.
7. Synchronize the PDB on the target container database by using the DBMS_PDS.SYNC_ODB function. Identify the correct order of the required steps.

  • A. 2, 1, 3, 4, 5, 6
  • B. 1, 3, 4, 5, 6, 7
  • C. 1, 4, 3, 5, 6, 7
  • D. 2, 1, 3, 4, 5, 6, 7
  • E. 1, 5, 6, 4, 3, 2

Answer: C

Explanation: 1. Set user tablespaces in the source database to READ ONLY.
2. From the Oracle Database 11g Release 2 {11.2.0.3) environment, export the metadata and any data residing in administrative tablespaces from the source database using the FULL=Y and TRANSPORTABLE=ALWAYS parameters.
Note that the VER$ION=12 parameter is required only when exporting from an Oracle Database llg Release 2 database:
3. Copy the tablespace data files from the source system to the destination system. Note that the log file from the export operation will list the data files required to be moved.
4. Create a COB on the destination system, including a PDB into which you will import the source database.
5. In the Oracle Database 12c environment, connect to the pre-created PDB and import the dump file. The act of importing the dump file will plug the tablespace data files into the destination PDB
