• Question 212:

  Your multitenant container (CDB) containing three pluggable databases (PDBs) is running in ARCHIVELOG mode. You find that the SYSAUX tablespace is corrupted in the root container.

  The steps to recover the tablespace are as follows:

  1.

  Mount the CDB.

  2.

  Close all the PDBs.

  3.

  Open the database.

  4.

  Apply the archive redo logs.

  5.

  Restore the data file.

  6.

  Take the SYSAUX tablespace offline.

  7.

  Place the SYSAUX tablespace online.

  8.

  Open all the PDBs with RESETLOGS.

  9.

  Open the database with RESETLOGS.

  10.

  Execute the command SHUTDOWN ABORT.

  Which option identifies the correct sequence to recover the SYSAUX tablespace?

  A. 6, 5, 4, 7

  B. 10, 1, 2, 5, 8

  C. 10, 1, 2, 5, 4, 9, 8

  D. 10, 1, 5, 8, 10

  Correct Answer: A

  RMAN> ALTER TABLESPACE sysaux OFFLINE IMMEDIATE;

  RMAN> RESTORE TABLESPACE sysaux;

  RMAN> RECOVER TABLESPACE sysaux;

  RMAN> ALTER TABLESPACE sysaux ONLINE;

  *

  Example:

  While evaluating the 12c beta3 I was not able to do the recover while testing "all pdb files lost".

  Cannot close the pdb as the system datafile was missing...

  So only option to recover was:

  Shutdown cdb (10)

  startup mount; (1)

  restore pluggable database

  recover pluggable database

  alter database open;

  alter pluggable database name open;

  Oracle support says: You should be able to close the pdb and restore/recover the system tablespace of

  PDB.

  Inconsistent backups are usually created by taking online database backups. You can also make an

  inconsistent backup by backing up data files while a database is closed, either:

  / Immediately after the crash of an Oracle instance (or, in an Oracle RAC configuration, all instances) / After shutting down the database using SHUTDOWN ABORT

  Inconsistent backups are only useful if the database is in ARCHIVELOG mode and all archived redo logs created since the backup are available.

  * Open the database with the RESETLOGS option after finishing recovery: SQL> ALTER DATABASE OPEN RESETLOGS;

• Question 213:

  Examine the following commands for redefining a table with Virtual Private Database (VPD) policies:

  

  Which two statements are true about redefining the table? (Choose two.)

  A. All the triggers for the table are disabled without changing any of the column names or column types in the table.

  B. The primary key constraint on the EMPLOYEES table is disabled during redefinition.

  C. VPD policies are copied from the original table to the new table during online redefinition.

  D. You must copy the VPD policies manually from the original table to the new table during online redefinition.

  Correct Answer: AC

  The triggers cloned to the interim table are disabled until the redefinition is completed. Once the redefinition is complete, all cloned objects are renamed to the original names used by they objects they were cloned from.

• Question 214:

  Which two statements are true about the use of the procedures listed in the v$sysaux_occupants.move_procedure column? (Choose two.)

  A. The procedures may be used for some components to relocate component data to the SYSAUX tablespace from its current tablespace.

  B. The procedures may be used for some components to relocate component data from the SYSAUX tablespace to another tablespace.

  C. All the components may be moved into SYSAUX tablespace.

  D. All the components may be moved from the SYSAUX tablespace.

  Correct Answer: AB

• Question 215:

  Which statement is true about Oracle Net Listener?

  A. It acts as the listening endpoint for the Oracle database instance for all local and non-local user connections.

  B. A single listener can service only one database instance and multiple remote client connections.

  C. Service registration with the listener is performed by the listener registration process (LREG) process of each database instance.

  D. The listener.ora configuration file must be configured with one or more listening protocol addresses to allow remote users to connect to a database instance.

  E. The listener.ora configuration file must be located in the ORACLE_HOME/network/admin directory.

  Correct Answer: C

• Question 216:

  An Automatic Database Diagnostic Monitor (ADDM) finding in your production database reports that the shared pool is inadequately sized. You diagnose that this is due to the different kinds of workloads and this occurs only during peak hours. The following are the parameter settings for the database instance: You want to balance the memory between the System Global Area (SGA) components depending on the workload.

  

  Which option would solve this problem?

  A. setting the PGA_AGGREGATE_TARGET parameter to 200M and the SGA_MAX_SIZE parameter to 400M

  B. setting the MEMORY_TARGET and SGA_MAX_SIZE parameters to 400M

  C. setting the SGA_TARGET parameter to 300M

  D. setting the SGA_MAX_SIZE parameter to 400M

  Correct Answer: C

• Question 217:

  Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB and

  ACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called temp01.tmp.

  A user issues a query on a table on one of the PDBs and receives the following error:

  ERROR at line 1:

  ORA-01565: error in identifying file `/u01/app/oracle/oradata/CDB1/temp01.tmp'

  ORA-27037: unable to obtain file status

  Identify two ways to rectify the error. (Choose two.)

  A. Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.

  B. Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.

  C. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.

  D. Shut down the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.

  E. Shut down the database instance and then restart the CDB and PDBs.

  Correct Answer: AE

  *

  Because temp files cannot be backed up and because no redo is ever generated for them, RMAN never restores or recovers temp files. RMAN does track the names of temp files, but only so that it can automatically re-create them when needed.

  *

  If you use RMAN in a Data Guard environment, then RMAN transparently converts primary control files to standby control files and vice versa. RMAN automatically updates file names for data files, online redo logs, standby redo logs, and temp files when you issue RESTORE and RECOVER.
