COMPRESSED enables binary compression.
RMAN compresses the data written into the backup set to reduce the overall size of the backup set. All backups that create backup sets can create compressed backup sets. Restoring compressed backup sets is no different from restoring uncompressed backup sets.
RMAN applies a binary compression algorithm as it writes data to backup sets. This compression is similar to the compression provided by many media manager vendors. When backing up to a locally attached tape device, compression provided by the media management vendor is usually preferable to the binary compression provided by BACKUP AS COMPRESSED BACKUPSET.
Therefore, use uncompressed backup sets and turn on the compression provided by the media management vendor when backing up to locally attached tape devices. You should not use RMAN binary compression andmedia manager compression together.
Some CPU overhead is associated with compressing backup sets. If the target database is running at or near its maximum load, then you may find the overhead unacceptable. In most other circumstances, compressing backup sets saves enough disk space to be worth the CPU overhead.
SECTION SIZE sizeSpec Specifies the size of each backup section produced during a data file backup. By setting this parameter, RMAN can create a multisection backup. In a multisection backup, RMAN creates a backup piece that contains one file section, which is a contiguous range of blocks in a file. All sections of a multisection backup are the same size. You can create a multisection backup for a data file, but not a data file copy.
File sections enable RMAN to create multiple steps for the backup of a single large data file. RMAN channels can process each step independently and in parallel, with each channel producing one section of a multisection backup set.
If you specify a section size that is larger than the size of the file, then RMAN does not use multisection backup for the file. If you specify a small section size that would produce more than 256 sections, then RMAN increases the section size to a value that results in exactly 256 sections. Depending on where you specify this parameter in the RMAN syntax, you can specify different section sizes for different files in the same backup job.
Note: You cannot use SECTION SIZE with MAXPIECESIZE or with INCREMENTAL LEVEL 1.2021-04- 01T21:58:00.52

NEW QUESTION 7
Your production database is running in archivelog mode. You use RMAN with a recovery catalog to back up your database to media and the database is uniquely identified in the recovery catalog.
You want to create a test database from the production database and allow the production database to remain open during the duplicate process. You restore the database backups to a new host with the same directory structure as the production database and want to use the recovery catalog for future backups after the database is successfully restored to the new host.
How would you achieve this?

A. by using the RMAN switch command to set the new location for the data files
B. by using the RMAN duplicate command with no filename check to recover the database to the new host
C. by using the RMAN duplicate command with dbid and set nekname for tablespace to recover the database to the new host
D. by creating a new database in the new host, and then using the RMAN recover command

NEW QUESTION 9
The CATDBI2c database contains an Oracle Database 12c catalog schema owned by the rc12c user. The CATDB11 database contains an Oracle Database l1g catalog schema owned by the RC11 user. A database with DBID=1423241 is registered in the CATDB11 catalog. Both the recovery catalog databases are open.
In the CATDB12c database, you execute the commands: Srman
RMAN> CONNECT CATALOG rc12c/pass12c@catdbI2c
RMAN> IMPOST CATALOG rc1l/pwdcatl11@catdbl1 DBID=I423241; What is the outcome of the import?

A. It fails because the target database and recovery catalog database are of different versions.
B. It succeeds and all global scripts in the RC11 catalog that have the same name as existing global scripts in the RC12C catalog are automatically renamed.
C. It succeeds but the database is not automatically registered in the Rc12c catalog.
D. It fails because RMAN is not connected to the target database with DBID=1423241.

Answer: A

Explanation: The version of the source recovery catalog schema must be equal to the current version of the destination recovery catalog schem
A. If they are not equal, then upgrade the schemas to the same version.

Which three statements are true about the process of automatic optimization by using statistics feedback?

A. The optimizer automatically changes a plan during subsequent execution of a SQL statement if there is a huge difference in optimizer estimates and execution statistics.
B. The optimizer can CK optimize a query only once using cardinality feedback.
C. The optimizer enables monitoring for cardinality feedback after the first execution of a query.
D. The optimizer does not monitor cardinality feedback if dynamic sampling and multicolumn statistics are enabled.
E. After the optimizer identifies a query as a re-optimization candidate, statistics collected by the collectors are submitted to the optimizer.

Answer: ACD

Explanation: C: During the first execution of a SQL statement, an execution plan is generated as usual.
D: if multi-column statistics are not present for the relevant combination of columns, the optimizer can fall back on cardinality feedback.
(not B)* Cardinality feedback. This feature, enabled by default in 11.2, is intended to improve plans for repeated executions.
optimizer_dynamic_sampling optimizer_features_enable
Dynamic sampling or multi-column statistics allow the optimizer to more accurately estimate selectivity of conjunctive predicates.
Note:
* OPTIMIZER_DYNAMIC_SAMPLING controls the level of dynamic sampling performed by the optimizer.
Range of values. 0 to 10
Cardinality feedback was introduced in Oracle Database 11gR2. The purpose of this feature is to automatically improve plans for queries that are executed repeatedly, for which the optimizer does not estimate cardinalities in the plan properly. The optimizer may misestimate cardinalities for a variety of reasons, such as missing or inaccurate statistics, or complex predicates. Whatever the reason for the misestimate, cardinality feedback may be able to help.

NEW QUESTION 12

A. It can contain a nested chain of jobs.
B. It can be used to implement dependency-based scheduling.
C. It cannot invoke the same program or nested chain in multiple steps in the chain.
D. It cannot have more than one dependency.
E. It can be executed using event-based or time-based schedule

Answer: ABE

Explanation: Chains are the means by which you can implement dependency based scheduling, in which jobs are started depending on the outcomes of one or more previous jobs.

NEW QUESTION 15
Examine the command and its output: SQL> DROP TABLE EMPLOYEE;
SQL> SELECT object_name AS recycle_name, original_name, type FROM recyclebin; RECYCLE_NAMEORIGINAL_NAMETYPE
--------------------------------------------------------------------------------------------------------------
binsgk31sj/3akk5hg3j21kl5j3d==$0EMPLOYEE TABLE
You then successfully execute the command:
SQL> FLASHBACK TABLE "BINSgk31sj/3akk5hg3j21kl5j3d==$0" TO BEFORE DROP;
Which two statements are true?

A. It flashes back the employee table and all the constraints associated with the table.
B. It automatically flashes back all the indexes on the employes table.
C. It automatically flashes back any triggers defined on the table.
D. It flashes back only the structure of the table and not the data.
E. It flashes back the data from the recycle bin and the existing data in the original table is permanently lost.

Answer: BC

Explanation: A table and all of its dependent objects (indexes, LOB segments, nested tables, triggers, constraints and so on) go into the recycle bin together, when you drop the table. Likewise, when you perform Flashback Drop, the objects are generally all retrieved together. Trigger automatically flashbacked. http://docs.oracle.com/cd/B19306_01/backup.102/b14192/flashptr004.htm#i1020594

Answer: A

Explanation: If you run multiple AUDIT statements on the same unified audit policy but specify different EXCEPT users, then Oracle Database uses the last exception user list, not any of the users from the preceding lists. This means the effect of the earlier AUDIT POLICY ... EXCEPT statements are overridden by the latest AUDIT POLICY ...
