Skills Gaged by 1Z0-063 and Other Key Details
The Oracle 1Z0-063 test measures various skills like the ones detailed below:
- Performing recovery and basic backup;
- Transporting databases and tablespaces;
- Database failure diagnosis and the use of the automatic diagnostic repository;
- Configuration and management of RMAN;
- Encrypting, monitoring, and securing RMAN backups;
- Operating the RMAN Recovery catalog;

- Performing recovery and restore operations.
The candidates who have taken the Oracle 1Z0-063 exam don’t have to do it again. This is because the Oracle Database 12c Administrator Certified Professional certificate does not have an expiration. So, once you get this designation, you can have confidence in the validation of your qualifications. To take this test, one has to register online at the Pearson VUE website. The exam is taken at Pearson VUE centers. The candidates are supposed to browse through the website to find out the nearest test center where they will take their exams.
Preparation Resources
Indeed, Oracle is focused on supporting each candidate and fostering his or her growth and quality training. This is why the official vendor recommends two optional courses to help the students prepare for the Oracle 1Z0-063 test:
- Oracle Database 12c: Backup and Recovery Workshop designed both for administrators and for everyone who wants to evaluate their own recovery skills. During virtual classes, you will get to know how to use Oracle Database recovery procedures and Flashback Technologies along with ways of diagnosing and fixing data failures. Moreover, through this real-time training, each candidate will gain a clear understanding of Oracle Database Cloud Service and learn how to optimize database workloads using backup and recovery procedures. In the end, the knowledge gained in this workshop will guarantee you a fast, reliable, secure, and easy increase in your Oracle database administration performance.
- At the same time, Oracle Database 12c: Managing Multitenant Architecture course will equip candidates with the relevant expertise to successfully pass 1Z0-063 exam by utilizing multitenant architecture. During this class, administrators and architects will discover why and how to create and manage a container database that is multitenant and how to deal with databases that are commonly pluggable, how to manage storage and security, and moreover, how to execute certain operations such as the transportation of Oracle Data Pump including encryption, loading, and auditing. These and other topics regarding managing Multitenant Architecture will be available when you sign up for the Live Virtual Class, which will ultimately aid in passing the Oracle 1Z0-063 test on the first try.
NEW QUESTION 92
The CATDB12C database contains an Oracle Database 12c catalog schema owned by the rci2c user.
The CATD3H database contains an Oracle Database Ug catalog schema owned by the rch user.
A database with dbid=H2324I is registered in the catdbII catalog. Both the recovery catalog databases are open.
In the CATD3i2c database, you execute the commands:
: r-ar.
RKAN> CONNECT CATALOG rci2c/passI2c@catdbi2c
RKAN> IMPORT CATALOG rcii/pwdcatUQcatdfoil DBI2=142324i;
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 but the database is not automatically registered in the rc:2c catalog.
- C. It fails because RMAN is not connected to the target database with r3:T=:42324:.
- D. It succeeds and all global scripts in the rci: catalog that have the same name as existing global scripts in the RCI2C catalog are automatically renamed.
Answer: D
NEW QUESTION 93
You are administering a multitenant container database (CDB) that has no startup triggers and contains three pluggable databases (PDBs).
You execute the command to start up the CDB.
SQL> STARTUP
Which statement is true?
- A. CDB$ROOT, PDB$SEED, and the PDBs are opened in read-only mode.
- B. CDB$ROOT and PDB$SEED are opened in read-only mode, but the PDBs are in closed mode.
- C. CDB$ROOT is opened in read/write mode, but PDB$SEED and the PDBs are in closed mode.
- D. CDB$ROOT, PDB$SEED, and the PDBs are opened in read/write mode.
- E. CDB$ROOT is opened in read/write mode, PDB$SEED in read-only mode, and the PDBs in MOUNT state.
Answer: E
Explanation:
Explanation
If neither READ WRITE nor READ ONLY is specified, a PDB will be opened in READ ONLY if a CDB to which it belongs is used as a physical standby database, otherwise the PDB will be opened READ WRITE.
Prerequisites for a PDB STARTUP
When the current container is a pluggable database (PDB), the STARTUP command can only be used if:
* The PDB is in MOUNTED mode, excluding the use of the FORCE option.
* The PDB must be in READ ONLY or READ WRITE mode to be in mounted mode.
Etc.

NEW QUESTION 97
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 data files by using the NOCATALOG option and use the SET NEWNAME command to change the location.
- B. Restore the control file from the backup by using the NOCATALOG option, and then restore and recover the data files.
- C. 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.
- D. 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.
Answer: D
Explanation:
Explanation
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:
SET NEWNAME FOR DATAFILE and SET NEWNAME FOR TEMPFILE
SET NEWNAME FOR TABLESPACE
SET NEWNAME FOR DATABASE

different storage tier, when the source tablespace exceeds T3S percent used
Answer: A,E
NEW QUESTION 99

- C. from the most recent incremental checkpoint
- D. from the last complete checkpoint position
- E. from the last committed transaction
Answer: D
Explanation:
Explanation/Reference:
Explanation: Have a recovery time governed by the number of terminated instances, amount of redo generated in each terminated redo thread since the last checkpoint, and by user-configurable factors such as the number and size of redo log files, checkpoint frequency, and the parallel recovery setting Reference https://docs.oracle.com/cd/B28359_01/server.111/b28318/startup.htm#CNCPT005
