QUESTION NO: 1
You create a table with the PERIOD FOR clause to enable the use of the Temporal Validity feature of Oracle Database 12c.
Examine the table definition:
Which three statements are true concerning the use of the Valid Time Temporal feature for the
EMPLOYEES table? (Choose three.)
A. The valid time columns are visible by default when the table is described.
B. The valid time columns are not populated by the Oracle Server automatically.
C. The same statement may filter on both transaction time and valid temporal time by using the AS
OF TIMESTAMP and PERIOD FOR clauses.
D. Setting the session valid time using DBMS_FLASHBACK_ARCHIVENABLE_AT_VALID_TIME sets the visibility for data manipulation language (DML), data definition language (DDL), and queries performed by the session.
E. The valid time columns employee_time_start and employee_time_end are automatically created.
Answer: C,D,E
Explanation
A: To implement Temporal Validity(TV), 12c offers the option to have two date columns in that table which is having TV enabled using the new clause Period For in the Create Table for the newly created tables or in the Alter Table for the existing ones. The columns that are used can be defined while creating the table itself and will be used in the Period For clause or you can skip having them in the table's definition in the case of which, the Period For clause would be creating them internally.
E: ENABLE_AT_VALID_TIME Procedure
This procedure enables session level valid time flashback.
QUESTION NO: 2
What is the effect of specifying the "ENABLE PLUGGABLE DATABASE" clause in a "CREATE
DATABASE" statement?
A. It will create a CDB that must be plugged into an existing CDB.
B. It will create a CDB with root opened and seed mounted.
C. It will create a CDB with root and seed opened and one PDB mounted.
D. It will create a CDB with root opened and seed read only.
E. It will create a multitenant container database (CDB) with only the root opened.
Answer: D
Explanation
* The CREATE DATABASE ... ENABLE PLUGGABLE DATABASE SQL statement creates a new CDB. If you do not specify the ENABLE PLUGGABLE DATABASE clause, then the newly created database is a non-
CDB and can never contain PDBs.
Along with the root (CDB$ROOT), Oracle Database automatically creates a seed PDB (PDB$SEED). The following graphic shows a newly created CDB:
* Creating a PDB
Rather than constructing the data dictionary tables that define an empty PDB from scratch, and then populating its Obj$ and Dependency $ tables, the empty PDB is created when the CDB is created.
(Here, we use empty to mean containing no customer-created artifacts.) It is referred to as the seed
PDB and has the name PDB $Seed. Every CDB non-negotiably contains a seed PDB; it is non-negotiably always open in read-only mode. This has no conceptual significance; rather, it is just an optimization device. The create PDB operation is implemented as a special case of the clone PDB operation.
QUESTION NO: 3
Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupted.
What should you do before executing the commands to restore and recover the data file in
ACCOUNTS_PDB?
A. Issue the ALTER PLUGGABLE DATABASE accounts_pdb OPEN RESTRICTED command.
B. Place CDB1 in the mount stage and then take the USERDATA tablespace offline in ACCOUNTS_PDB
.
C. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE
IMMEDIATE command.
D. Take the USERDATA tablespace offline in ACCOUNTS_PD
Answer: D
Explanation
* You can take an online tablespace offline so that it is temporarily unavailable for general use. The rest of the database remains open and available for users to access data. Conversely, you can bring an offline tablespace online to make the schema objects within the tablespace available to database users. The database must be open to alter the availability of a tablespace.
QUESTION NO: 4
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. Shut down the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.
B. Shut down the database instance and then restart the CDB and PDBs.
C. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.
D. Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.
E. Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.
Answer: B,D
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.
QUESTION NO: 5
You notice a high number of waits for the db file scattered read and db file sequential read events in the recent Automatic Database Diagnostic Monitor (ADDM) report. After further investigation, you find that queries are performing too many full table scans and indexes are not being used even though the filter columns are indexed.
Identify three possible reasons for this. (Choose three.)
A. Undersized shared pool
B. Missing or stale histogram statistics
C. High value for the DB_FILE_MULTIBLOCK_READ_COUNT parameter
D. High clustering factor for the indexes
E. Oversized buffer cache
Answer: B,C,D
Explanation
D: DB_FILE_MULTIBLOCK_READ_COUNT is one of the parameters you can use to minimize I/O during table scans. It specifies the maximum number of blocks read in one I/O operation during a sequential scan.
The total number of I/Os needed to perform a full table scan depends on such factors as the size of the table, the multiblock read count, and whether parallel execution is being utilized for the operation.
