NEW QUESTION 1
Which two statements are true about scheduling operations in a pluggable database (PDB)?

  • A. Scheduler jobs for a PDB can be defined only at the container database (CDB) level.
  • B. A job defined in a PDB runs only if that PDB is open.
  • C. Scheduler attribute setting is performed only at the CDB level.
  • D. Scheduler objects created by users can be exported or imported using Data Pump.
  • E. Scheduler jobs for a PDB can be created only by common user

Answer: BD

Explanation: In general, all scheduler objects created by the user can be exported/imported into the PDB using data pump. Predefined scheduler objects will not get exported and that means that any changes made to these objects by the user will have to be made once again after the database has been imported into the pluggable database. However, this is how import/export works currently. A job defined in a PDB will run only if a PDB is open.

NEW QUESTION 2
Examine the RMAN command:
RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON; RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which prerequisite must be met before accomplishing the backup?

  • A. The password for the encryption must be set up.
  • B. Oracle wallet for the encryption must be set up.
  • C. All the tablespaces in the database must be encrypted.
  • D. Oracle Database Vault must be enabled.

Answer: B

Explanation:
Configuration encryption will used by Transparent encryption. For transparent encryption, you will need to create a wallet, and it must be open. Transparent encryption will then occur automatically
after you have issued the CONFIGURE ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command. http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmbckad.htm#CEGEJABH
CONFIGURE ENCRYPTION : You can use this command to persistently configure transparent encryption. You cannot persistently configure dual mode or password mode encryption. SET ENCRYPTION : You can use this command to configure dual mode or password mode encryption at the RMAN session level.

NEW QUESTION 3
You want to reduce fragmentation and reclaim unused space for the sales table but not its dependent objects. During this operation, you want to ensure the following:

  • A. i.Long-running queries are not affecte
  • B. ii.No extra space is used.ii
  • C. Data manipulation language (DML) operations on the table succeed at all times throughout the process.i
  • D. Unused space is reclaimed both above and below the high water mar
  • E. Which alter TABLE option would you recommend?
  • F. DEALLOCATE UNUSED
  • G. SHRINK SPACE CASCADE
  • H. SHRINK SPACE COMPACT
  • I. ROW STORE COMPRESS BASIC

Answer: C

Explanation: The COMPACT clause lets you divide the shrink segment operation into two phases. When you specify COMPACT, Oracle Database defragments the segment space and compacts the table rows but postpones the resetting of the high water mark and the deallocation of the space until a future time. This option is useful if you have long-running queries that might span the operation and attempt to read from blocks that have been reclaimed. The defragmentation and compaction results are saved
to disk, so the data movement does not have to be redone during the second phase. You can reissue the SHRINK SPACE clause without the COMPACT clause during off-peak hours to complete the second phase.

NEW QUESTION 4
Examine these parameter settings: SGA_TARGET = 700M SGA_MAX_SIZE = 1024M DB_8K_CACHE_SIZE = 124M LOG_BUFFER = 200M
You attempt this:
SQL> ALTER SYSTEM SER DB_8K_CACHE_SIZE=140M
Which statement is true based on the information available?

  • A. It will fail because DB_8K_CACHE_SIZE cannot be changed dynamically.
  • B. It succeeds only if memory is available from the autotuned components of the SGA.
  • C. It will fail because an increase in DB_8K_CACHE_SIZE cannot be accommodated within SGA_TARGET.
  • D. It will fail because an increase in DB_8K_CACHE_SIZE cannot be accommodated within SGA_MAX_SIZE.

Answer: B

NEW QUESTION 5
Which three RMAN persistent settings can be set for a database?

  • A. backup retention policy
  • B. default backup device type
  • C. default section size for backups
  • D. default destinations for backups
  • E. multiple backup device types for a single backup

Answer: ABD

Explanation: http://docs.oracle.com/cd/B19306_01/backup.102/b14192/setup004.htm#i1019739 To simplify
ongoing use of RMAN, you can set several persistent configuration settings for each target database. These settings control many aspects of RMAN behavior. For example, you can configure the backup retention policy, default destinations for backups, default backup device type, and so on. You can use the SHOW and CONFIGURE commands to view and change RMAN configurations.

NEW QUESTION 6
You are administering a database that supports a data warehousing workload and is running in noarchivelog mode. You use RMAN to perform a level 0 backup on Sundays and level 1 incremental backups on all the other days of the week.
One of the data files is corrupted and the current online redo log file is lost because of a media failure.
Which action must you take for recovery?

  • A. Restore the data file, recover it by using the recover datafilenoredo command, and use the resetlogs option to open the database.
  • B. Restore the control file and all the data files, recover them by using the recover database noredo command, and use the resetlogs option to open the database.
  • C. Restore all the data files, recover them by using the recover database command, and open the database.
  • D. Restore all the data files, recover them by using the recover database noredo command, and use the resetlogs option to open the database.

Answer: B

Explanation: https://docs.oracle.com/database/121/RCMRF/rcmsynta2001.htm#RCMRF140 See Example 3-6
Recovering a NOARCHIVELOG Database STARTUP FORCE NOMOUNT; RESTORE CONTROLFILE; #

NEW QUESTION 7
Examine the initialization parameter that is set in the PFILE: DB_CREATE_FILE_DEST ='/u01/app/oracle/oradata/'
You execute the following command to create theCDB1. container database (CDB): SQL>CREATE DATABASE CDB1
DEFAULT TABLESPACE users
DEFAULT TEMPORARY TABLESPACE temp
UNDO TABLESPACE undotbsl
ENABLE PLUGGABLE DATABASE SEED
SYSTEM DATAFILES SIZE125M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED SYS AUX DATAFILES SIZE 100M;
Which three statements are true?

  • A. It creates a multitenant container database with a root and a seed pluggable database (PDB) that are opened in read-write and read-only modes, respectively.
  • B. The files created for both the root and seed databases use Oracle Managed Files (OMF).
  • C. It creates a multitenant container database with the root and seed databases opened and one PDB mounted.
  • D. It sets the users tablespace as the default for both the root and seed databases.
  • E. undotbs1 is used as the undo tablespace for both the root and seed databases.
  • F. It creates a multitenant container database with the root database opened and the seed database mounted.

Answer: ABE

Explanation: The seed actually doesn’t use anything since it’s read-only, but any PDB created from the seed will use the undotbs1 undo tablespace. Each PDB can have its own default tablespace, but cannot change the undo tablespace.

NEW QUESTION 13
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

Explanation: 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 the SQL operations the database has processed for a given object.
* The Oracle SQL optimizer has always been ignorant of the implied relationships between data 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.
