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.)

  1. Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.
  2. Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.
  3. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.
  4. Shut down the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.
  5. Shut down the database instance and then restart the CDB and PDBs.

Answer(s): A,E

Explanation:

* 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.



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

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

  1. All the triggers for the table are disabled without changing any of the column names or column types in the table.
  2. The primary key constraint on the EMPLOYEES table is disabled during redefinition.
  3. VPD policies are copied from the original table to the new table during online redefinition.
  4. You must copy the VPD policies manually from the original table to the new table during online redefinition.

Answer(s): A,C

Explanation:

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.

    tablespace to another tablespace.

Which statement is true about Oracle Net Listener?

  1. It acts as the listening endpoint for the Oracle database instance for all local and non-local user connections.
  2. A single listener can service only one database instance and multiple remote client connections.
  3. Service registration with the listener is performed by the listener registration process (LREG) process of each database instance.
  4. 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.
  5. The listener.ora configuration file must be located in the ORACLE_HOME/network/admin directory.

Answer(s): C
