B. RMAN skips the backup of the tools tablespace because backup optimization is enabled.
C. RMAN creates a backup of the tools tablespace because backup optimization is applicable only for the backups written to media.

NEW QUESTION 11
Identify three scenarios in which RMAN will use backup sets to perform active database duplication.

A. when the duplicate ... from active database command contains the section size clause
B. when you perform active database duplication on a database with flashback disabled
C. when you specify set encryption before the duplicate ... from active database command
D. when the number of auxiliary channels allocated is equal to or greater than the number of target channels
E. when you perform active database duplication on a database that has read-only tablespaces

Answer: ACD

Explanation: Starting with Oracle Database 12c Release 1 (12.1), RMAN can use backup sets to transfer the source database files that need to be duplicated. The backup sets are transferred over the network to the auxiliary database. Backup sets can be encrypted for additional security. Specify the encryption
algorithm by using the SET ENCRYPTION ALGORITHM command before the DUPLICATE command. RMAN uses backup sets to perform active database duplication when the connection to the target database is established using a net service name and any one of the following conditions is satisfied:
The DUPLICATE ... FROM ACTIVE DATABASE command contains either the USING BACKUPSET, USING
COMPRESSED BACKUPSET, or SECTION SIZE clause. The number of auxiliary channels allocated is equal to or greater than the number of target channels allocated. http://docs.oracle.com/database/121/BRADV/rcmdupdb.htm#BRADV298

NEW QUESTION 12

SQL> GRANT CREATE SESSION to C##ADMIN CONTAINER=ALL; SQL> GRANT CREATE USER TO C##ADMIN CONTAINER=ALL;
Which two statements are true about the c##admin user that is created in all PDBs?

A. It can create only local users in all the PDBs.
B. It has a common schema for all the PDBs.
C. It can create common users only when it is logged in to the CDB.
D. It can create only local users in the CDB.
E. It can be granted only common roles in the PDBs.

Answer: BC

A. when one or more disks in an ASM disk group are lost
B. when the data file on an ASM disk group gets corrupted
C. when one of the disks in a disk group is accidentally unplugged
D. when one or more file directory paths are accidentally deleted from an ASM disk group
E. when all the ASM disk groups for the ASM instance are lost

Answer: ADE

Explanation: http://www.hhutzler.de/blog/asm-backup-and-restore-dg-metadata/
The md_backup command creates a backup file containing metadata for one or more disk groups. i By default all the mounted disk groups are included in the backup file which is saved in the current working directory. http://docs.oracle.com/cd/E11882_01/server.112/e18951/asm_util004.htm#OSTMG94578
The md_backup command creates a backup file containing metadata for one or more disk groups.

NEW QUESTION 17
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.

NEW QUESTION 18
Which three statements are true about persistent lightweight jobs?

A. A user cannot set privileges on them.
B. They generate large amounts of metadata.
C. They may be created as fully self-contained jobs.
D. They must reference an existing Scheduler Program.
E. The are useful when users need to create a large number of jobs quickl

Answer: ADE

Explanation: Unlike regular jobs, they are not schema objects. Because lightweight jobs are not schema objects, you cannot grant privileges on them. A lightweight job inherits privileges from its specified program. Thus, any user who has a certain set of privileges on the program has corresponding privileges on the lightweight job. Use lightweight jobs when you have many short-duration jobs that run frequently. Under certain circumstances, using lightweight jobs can deliver a small performance gain. A lightweight job must reference a program object (program) to specify a job action. The program must be already enabled when the lightweight job is created, and the program type must be either ‘PLSQL_BLOCK’ or ‘STORED_PROCEDURE’.
