You are using a recovery catalog to maintain Recovery Manager (RMAN) backup information for your production database. You have registered your production database and are performing regular backups. Because of a new requirement you have added a few new tablespaces to your production database and you want them to be included in backups. Identify two options for completing this task. (Choose two.)
A. Reregistering the target database in recovery catalog
B. Transporting the new tablespaces to the recovery catalog database
C. Syncronizing the recovery catalog with the target database control file
D. Performing a fresh backup of the target database to include the new data files in the catalog database
View the Exhibit to examine the output produced by the following query at three different times since the database instance started and has undergone workloads of different capacities:
SQL> SELECT substr(component, 0, 10) COMP, current_size CS, user_specified_size US
What do you infer from this?
A. All sessions are connected to the database instance in dedicated mode, and no RMAN or parallel
query operations have been performed.
B. The database instance is running with manual shared memory management.
C. The database instance is running with manual PGA management.
D. The database instance has the MEMORY_TARGET value set to a nonzero value.
View the Exhibit to observe the error.
A. setting the PRE_PAGE_SGA parameter to TRUE
B. locking the SGA in memory
C. increasing the value of SGA_MAX_SIZE
D. automatic memory management
A. The incident has been newly created and is in the process of collecting diagnostic information.
B. The incident is now in the Done state and the ADR can select the incident to be purged.
C. The DBA is working on the incident and prefers that the incident be kept in the ADR.
D. The data collection for the incident is complete and the incident can be packaged and sent to Oracle Support.

In the CUSTOMERS_OBE table, when the value of CUST_STATE_PROVINCE is “CA”, the value of COUNTRY_ID is “US.”
View the Exhibit exhibit2 to examine the commands and query plans. The optimizer can sense 8 rows instead of 29 rows, which is the actual number of rows in the table. What can you do to make the optimizer detect the actual selectivity?
A. Change the STALE_PERCENT value for the CUSTOMERS_OBE table.
B. Set the STATISTICS_LEVEL parameter to TYPICAL.
C. Create extended statistics for the CUST_STATE_PROVINCE and CUSTOMERS_OBE columns.
D. Set the OPTIMIZER_USE_PENDING_STATISTICS parameter to FALSE.
View the Exhibit and examine the output.
You executed the following command to enable Flashback Data Archive on the EXCHANGE_RATE table:
ALTER TABLE exchange_rate FLASHBACK ARCHIVE;
What is the outcome of this command?
A. The Flashback Archive is created on the same tablespace where the tables are stored.
B. The Flashback Archive is created on the SYSAUX tablespace.
C. The command generates an error because no Flashback Archive name is specified and there is no
default Flashback Archive.
D. The table uses the default Flashback Archive.
Exhibit #1: Exhibit #2:
View the Exhibits exhibit1 and exhibit2.
Both the processes use PROG_1 as the job template that is already available. The time taken by the jobs are recorded in the TEST_LOG table. While comparing the time taken to create the jobs, the process in exhibit1 takes less time than the process in exhibit2. What is the reason for this?
A. It updates several tables in the SYSTEM tablespace instead of creating new tables.
B. It creates jobs temporarily in memory only.
C. It creates less metadata for the jobs.
D. It writes the job metadata to disk in compressed format.
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.
Lightweight jobs have the following characteristics:
Unlike regular jobs, they are not schema objects.
They have significantly better create and drop times over regular jobs because they do not have the overhead of creating a schema object.
They have lower average session create time than regular jobs.
They have a small footprint on disk for job metadata and run-time data.
You designate a lightweight job by setting the job_style job attribute to ‘LIGHTWEIGHT’. The other job style is ‘REGULAR’, which is the default.
Like programs and schedules, regular jobs are schema objects. In releases before Oracle Database 11g Release 1, the only job style supported by the Scheduler was regular.
A regular job offers the maximum flexibility but does entail some overhead when it is created or dropped. The user has fine-grained control of the privileges on the job, and the job can have as its action a program or a stored procedure owned by another user.
If a relatively small number of jobs that run infrequently need to be created, then regular jobs are preferred over lightweight jobs.
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’. 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.

Which statement is true about the block corruption detected by the command?
A. No action is taken except the output in the Exhibit.
B. The ADVISE FAILURE command is automatically called to display the repair script.
C. The failure is logged into the Automatic Diagnostic Repository (ADR).
D. The corruption is repaired by the command implicitly.
A. RESOURCE_PERCENTAGE should be increased.
B. The repeat time for the window should be decreased.
C. RESOURCE_PERCENTAGE should be decreased.
D. The window duration should be increased.
ASM supports all but which of the following file types? (Choose all that apply.)
A. Database files
C. Redo-log files
D. Archived log files
E. RMAN backup sets
F. Password files
G. init.ora files
