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.

QUESTION 23
You want to capture column group usage and gather extended statistics for better
cardinality estimates for the customers table in the SH schema.
Examine the following steps:
1. Issue the SELECTDBMS_STATS. CREATE_EXTENDED_STATS (`SH',
'CUSTOMERS') from dual statement.
2. Execute the dbms_stats.seed_col_usage (null, `SH', 500) procedure.
3. Execute the required queries on the customers table.
4. Issue the select dbms_stats.reportwcol_usage (`SH', 'customers') from dual
statement.
Identify the correct sequence of steps.
A. 3, 2, 1, 4
B. 2, 3, 4, 1
C. 4, 1, 3, 2
D. 3, 2, 4, 1
Answer: B
Step 1 (2). Seed column usage
Oracle must observe a representative workload, in order to determine the appropriate
column groups.
Using the new procedure DBMS_STATS.SEED_COL_USAGE, you tell Oracle how
long it should observe the workload.
Step 2: (3) You don't need to execute all of the queries in your work during this
window. You can simply run
explain plan for some of your longer running queries to ensure column group
information is recorded for these queries.
Step 3. (1) Create the column groups
At this point you can get Oracle to automatically create the column groups for each of
the tables based on the usage information captured during the monitoring window.
You simply have to call the
DBMS_STATS.CREATE_EXTENDED_STATS function for each table.This
function requires just two arguments, the schema name and the table name. From then
on, statistics will be maintained for each column group whenever statistics are
gathered on the table.
Note:
* DBMS_STATS.REPORT_COL_USAGE reports column usage information and
records all t e SQL
operations the database has processed for a given object.
* The Oracle SQL optimizer has always been ignorant of the implied relationships
between ata columns within the same table. While the optimizer has traditionally
analyzed the distribution of values within a column, he does not collect value-based
relationships between columns.
* Creating extended statistics
Here are the steps to create extended statistics for related table columns
withdbms_stats.created_extended_stats:
1 - The first step is to create column histograms for the related columns. 2 ?Next, we
run
dbms_stats.create_extended_stats to relate the columns together. Unlike a traditional
procedure that is invoked via an execute ("exec") statement, Oracle extended statistics
are created via a select statement.、

* Smart Flash Cache concept is not new in Oracle 12C - DB Smart Flash Cache in
Oracle 11g. In this
release Oracle has made changes related to both initialization parameters used by DB
Smart Flash cache.
Now you can define many files|devices and its sizes for "Database Smart Flash
Cache" area. In previous releases only one file|device could be defined.
DB_FLASH_CACHE_FILE = /dev/sda, /dev/sdb, /dev/sdc
DB_FLASH_CACHE_SIZE = 32G, 32G, 64G
So above settings defines 3 devices which will be in use by "DB Smart Flash Cache"
/dev/sda ?size 32G
/dev/sdb ?size 32G
/dev/sdc ?size 64G
New view V$FLASHFILESTAT ?it's used to determine the cumulative latency and
read counts f each file| device and compute the average latency

This example example is a dumpfile-based full transportable export/import operation.
In this case the
metadata from the source database is exported to a dump file, and both the dump file
and the tablespace
data files are transferred to a new system. The steps would be as follows:
* (1) Set user tablespaces in the source database to READ ONLY.
* (3) Create a CDB on the destination system, including a PDB into which you will
import the source
database.
* (4) 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 VERSION=12 parameter
is required only when
exporting from an Oracle Database 11g Release 2 database.
* (5) Copy the tablespace data files from the source system to the destination system.
* (6) In the Oracle Database 12c environment, connect to the pre-created PDB and
import the dump file.

QUESTION 177
You plan to uplicate the multitenant container database (CDB) cdb1 that contains the
pluggable database (PDB) SALES:
Which two statements are true? (Choose two.)
A. The root and seed databases are included in the duplication.
B. Only the SALES PDB is duplicated as the non-CDB CDBDUP.
C. A backup of the SALES PDB must exist before the execution of the command.
D. An auxiliary instance must have been started with the initialization parameter
ENABLE_PLUGGABLE_DATABASE set to TRUE.
E. RMAN must be connected to a recovery catalog for the execution of the command.
Answer: AD
D: When duplicating a whole CDB or one more PDBs:
You must create the auxiliary instance as a CDB. To do so, start the instance with the
following declaration
in the initialization parameter file:
enable_pluggable_database=TRUE
A: To duplicate PDBs, you must create the auxiliary instance as a CDB. To do so,
start the instance with the declaration enable_pluggable_database=TRUE in the
initialization parameter file. When you duplicate one or more PDBs, RMAN also
duplicates the root (CDB$ROOT) and the seed database (PDB$SEED). The resulting
duplicate database is a fully functional CDB that contains the root, the seed database,
and the duplicated PDBs.

QUEST ON 179
Your database is running on the host OUSERVER. You back up your database
regularly using RMAN and the backups are cataloged in a recovery catalog. For
testing purposes, you want to replicate your database to another host, OUSERVER1,
with the same directory structure. So, you copy the backups to the new host.
What must you do to make the database operational in OUSERVER1?
A. Restore the control file from the backup by using the CATALOG option, restore
the data files by using the SET NEWNAME command, and recover the data files.
B. Restore the data files by using the NOCATALOG option and use the SET
NEWNAME command to change the location.
C. Restore the control file from the backup by using the NOCATALOG option, and
then restore and recover the data files.
D. Restore the data files from the backup by using the recovery catalog, use the
SWITCH command to change the location, and recover the data files.
Answer: A
Catalog any backups not recorded in the repository with the CATALOG command.
Restore the data files to their original locations. If volume names have changed, then
run SET NEWNAME commands before the restore operation and perform a switch
after the restore operation to update the control file with the new locations for the data
files, as shown in the following example.
Note: One way to name duplicate data files is to use the SET NEWNAME command
before executing the DUPLICATE command. RMAN supports the following
commands, listed in order of precedence:

Examine the list of possible steps to transport a tablespace across platforms that have
the same compatibility level, character sets, and endian format:
1. Make the tablespace read-only at the source database.
2. Export metadata from the source database.
3. Import metadata into the target database.
4. Transfer the dump file and data files to the target machine.
5. Convert data files by using Recovery Manager (RMAN).
6. Make the tablespace read-write at the target database.

A. 2, 4, and 3B. 2, 4, 3, and 5
C. 1, 5, 2, 4, 3, and 6
D. 1, 2, 4, 3, and 6
Answer: D
Explanatio Reference:
Step 1 (1): To copy tablespaces from one database to another using transportable
tablespace, the source
tablespa s are first kept in READ-ONLY mode (to ensure data consistency). Once
the tablespaces are in READ-ONLY mode, the actual datafiles belonging to the
source tablespaces are copied from source
database to target database (using any available methods like scp, sftp, rcp, etc). Step
2 (2): Once the tablespace is kept in READ-ONLY mode, we need to generate the
metadata export of the tablespaces that
needs to transported using the DataPump export utility. Step 3 (4): Once the metadata
export is generated on the source database for all the tablespaces that needs to be
transported, we need to copy the Export
Dump file as well as all the datafiles belonging to the tablespaces to be transported to
the target database server.

QUESTION 181
In which three situations must you use a recovery catalog? (Choose three.)
A. when you want to store RMAN global scripts that can be used across multiple
databases
B. when you want to restrict the amount of space used by backups
C. when you want to perform incremental backups by using a block change tracking
file
D. when you want to list data files that were in a target database at a given time by
using the AT clause with the REPORT SCHEMA command
E. when you want to maintain backup metadata longer than the period specified by
the CONTROL_FILE_RECORD_KEEP_TIME parameter
Answer: ADE
A: Some RMAN features function only when you use a recovery catalog. For
example, you can store RMAN scripts in a recovery catalog. The chief advantage of a
stored script is that it is available to any RMAN client that can connect to the target
database and recovery catalog. Command files are only available if the RMAN client
has access to the file system on which they are stored. A local stored script is
associated with
the target database to which RMAN is connected when the script is created, and can
only be executed when you are connected to this target database. A global stored
script can be run against any database registered in the recovery catalog.
D: If you use a recovery catalog, then you can use the atClause to specify a past time,
SCN, or log sequence number, as shown in these examples of the command:
RMAN> REPORT SCHEMA AT TIME 'SYSDATE-14'; # schema 14 days ago
RMAN> REPORT SCHEMA
AT SCN 10 0; # schema at scn 1000
RMAN> REPORT SCHEMA AT SEQUENCE 100 THREAD 1; # schema at
sequence 100 RMAN>
REPOR SCHEMA FOR DB_UNIQUE_NAME standby1;
E: The CONTROL_FILE_RECORD_KEEP_TIME initialization parameter
determines the minimum number of days that records are retained in the control file
before they are candidates for being overwritten. Thus,
you must ensure that you resynchronize the recovery catalog with the control file
records before these records are erased.

Which two statements are true about setting the FAST_START_MTTR_TARGET
parameter to a nonzero value? (Choose two.)
A. The MTTR advisor is enabled only if the value is greater than the default value.
B. Automatic checkpoint tuning is enabled.
C. The value of the LOG_CHECKPOINT_INTERVAL parameter overrides the value
of the FAST_START_MTTR_TARGET parameter.
D. The time taken to recover an instance after a crash is always exactly the same as
the value set or the FAST_START_MTTR_TARGET parameter.
Answer: AC
Explana on
The FAST_START_MTTR_TARGET initialization parameter lets you specify in
seconds the expected "mean time to recover" (MTTR), which is the expected amount
of time Oracle takes to perform crash or instance recovery for a single instance.
To enable MTTR advisory, set the initialization parameter
FAST_START_MTTR_TARGET to a nonzero
value. If FAST_START_MTTR_TARGET is not specified, then MTTR advisory will
be OFF. When specified,
FAST_START_MTTR_TARGET is overridden by
LOG_CHECKPOINT_INTERVAL. Note: The default value
is 0. Range of values is 0 to 3600 seconds.

You are connected to a recovery catalog and target database. You execute the
command:RMAN> CATALOG START WITH `/disk1/backups';
Which statement is true?
A. Only valid data file copies, existing in the /disk1/backups directory, are cataloged.
B. Only valid backup pieces and archived logs, existing in the /disk1/backups
directory, are cataloged.
C. It lists all data file copies, backup pieces, and achieved logs cataloged in the
recovery catalog in the / disk1/backups directory and its subdirectories.
D. It lists and catalogs all valid data file copies, backup pieces, and archived logs that
exist in all directory paths with the prefix /disk1/backups and their subdirectories.
Answer: D
If you have data file copies, backup pieces, or archived logs on disk, then you can
catalog them in the recovery catalog with the CATALOG command.
The followi g command catalogs all files in all of these directories, because
/disk1/backups is a prefix for the paths for all of these directories:
CATALOG START WITH '/disk1/backups'; To catalog only backups in the
/disk1/b kups directory, the correct command is as follows:

QUESTION 190
Which three statements are true about the database instance startup after an instance
failure? (Choose three.)
A. The RECO process recovers the uncommitted transactions at the next instance
startup.
B. Online redo log files and archived redo log files are required to complete the
rollback stage of instance recovery.
C. Uncommitted changes are rolled back to ensure transactional consistency.
D. The SMON process coordinates the database recovery.
E. Media recovery is required to complete the database recovery.
F. Changes committed before the failure, which were not written to the data files, are
re-applied.
Answer: ACD
A: Occasionally a database closes abnormally with one or more distributed
transactions in doubt (neither committed nor rolled back). When you reopen the
database and recovery is complete, the RECO background process automatically,
immediately, and consistently resolves any in-doubt distributed transactions.
C: Crash and instance recovery involve two distinct operations: rolling forward the
current, online datafiles by applying both committed and uncommitted transactions
contained in online redo records, and then rolling back changes made in uncommitted
transactions to their original state.
D: The SMON background process performs instance recovery, applying online redo
automatically.
No user intervention is required.

This example is a dumpfile-based full transportable export/import operation. In this
case the metadata from
the source database is exported to a dump file, and both the dump file and the
tablespace data files are
transferred to a new system. The steps would be as follows:
* (2) Set user tablespaces in the source database to READ ONLY.
* (5) Create a CDB on the destination system, including a PDB into which you will
import the source
database.
* (1) 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
VERSION=12 parameter is required only when exporting from an Oracle Database
11g Release 2 database.
* (4) Copy the tablespace data files from the source system to the destination system.
* (7) In the Oracle Database 12c environment, connect to the pre-created PDB and
import the dump file.

QUESTION 192
RMAN is connected to a target database instance and an auxiliary instance. You
execute the command:
What is the outcome?
A. RMAN uses the push method to transfer image copies.
B. RMAN uses the push method to transfer backup sets.
C. RMAN uses the pull method to restore files using backup sets.
D. RMAN uses the pull method to restore files using image copies.
Answer: C
When RMAN performs active database duplication using backup sets, a connection is
established with the source database and the auxiliary database. The auxiliary
database then connects to the source database through Oracle Net Services and
retrieves the required database files from the source database. This method of active
database duplication is also to as the pull-based method.

QUESTION 194
You regularly take backups of your database using RMAN with a recovery catalog.
Your database is currently open and the temp01.dbf temp file belonging to the TEMP
tablespace is corrupted. Identify two methods to recover the temp file with the least
disruption to database availability.
(Choose two.)
A. Drop the TEMP tablespace, and then re-create it with new temp files.
B. Restart th database instance to create the temp file automatically.
C. Take the TEMP tablespace offline, drop the missing temp file, and then create a
new temp file.
D. Add new temp file to the TEMP tablespace with a new name, and then drop the
temp file that is corrupted.
Answer: BC
Temp files are a special class of data files that are associated only with temporary
tablespaces.
B: After restore and recovery of a whole database, when the database is open, missing
temporary tablespaces that were recorded in the control file are re-created with their
previous creation size,
AUTOEXTEND, and MAXSIZE attributes. Only temporary tablespaces that are
missing are re-created. If a temp file exists at the location recorded in the RMAN
repository but has an invalid header, then RMAN does not re-create the temp file.
If the temp files were created as Oracle-managed files, then they are re-created in the
current DB_CREATE_FILE_DEST location. Otherwise, they are re-created at their
previous locations.
C: If a data file becomes missing or corrupted. You must take it offline before you can
open the database.

QUESTION 198
You execute the command to recover your database:
Which statement is true?
A. It restores all data files from the specified time, and then applies the redo logs.
B. It restores all data files, redo log files, and control files, and then applies the redo
logs up to the specified time.
C. It restores all data files and control files from the most recent backup taken before
the "until time", and then recovers up to the "until time" using any restored archive
logs that are needed to complete the task.
D. It restores the control file and all data files from the most recent backups, and then
applies the redo logs up to the "until time".
Answer: C
UNTIL TIME = 'date_string' specifies a time as an upper limit. RMAN selects only
files that can be used to restore and recover up to but not including the specified time.
RMAN can perform recovery of the whole database to a specified past time, SCN, or
log sequence number. This type of recovery is sometimes called incomplete recovery
because it does not completely use all of the available redo. Incomplete recovery of
the whole da abase is also called database point-in-time recovery (DBPITR).
DBPITR requires restoring your database from an older backup, then performing
media recovery until your specified target time, SCN or log sequence number. Note
that beca se you need your archived redo log files to perform this process, you cannot
perform database point-in-time recovery if you have been running your database in
NOARCHIVELOG mode.
