NO.1 Which statement is true about Oracle Net Listener?
A. It acts as the listening endpoint for the Oracle database instance for all local and non-local user
connections.
B. A single listener can service only one database instance and multiple remote client connections.
C. Service registration with the listener is performed by the process monitor (PMON) process of
each database instance.
D. The listener.ora configuration file must be configured with one or more listening protocol
addresses to allow remote users to connect to a database instance.
E. The listener.ora configuration file must be located in the ORACLE_HOME/network/admin directly.
Answer: C

Explanation:
Supported services, that is, the services to which the listener forwards client
requests, can be configured in the listener.ora file or this information can be dynamically
registered with the listener. This dynamic registration feature is called service registration.
The registration is performed by the PMON process-an instance background process-of
each database instance that has the necessary configuration in the database initialization
parameter file. Dynamic service registration does not require any configuration in the
listener.ora file.
Incorrect:
Not B:Service registration reduces the need for the SID_LIST_listener_name parameter
setting, which specifies information about the databases served by the listener, in the
listener.ora file.
Note:
*Oracle Net Listener is a separate process that runs on the database server computer. It
receives incoming client connection requests and manages the traffic of these requests to
the database server.
*A remote listener is a listener residing on one computer that redirects connections to a
database instance on another computer. Remote listeners are typically used in an Oracle
Real Application Clusters (Oracle RAC) environment. You can configure registration to
remote listeners, such as in the case of Oracle RAC, for dedicated server or shared server
environments.
NO.2 You are administering a database stored in Automatic Storage Management (ASM). You
use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata
regularly. You lost an ASM disk group DG1 due to hardware failure.
In which three ways can you re-create the lost disk group and restore the data?
A. Use the MD_RESTORE command to restore metadata for an existing disk group by passing the
existing disk group name as an input parameter and use RMAN to restore the data.
B. Use the MKDG command to restore the disk group with the same configuration as the backed-up
disk group and data on the disk group.
C. Use the MD_RESTORE command to restore the disk group with the changed disk group
specification, failure group specification, name, and other attributes and use RMAN to restore the
data.
D. Use the MKDG command to restore the disk group with the same configuration as the backed-up
disk group name and same set of disks and failure group configuration, and use RMAN to restore
the data.
E. Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.
F. Use the MKDG command to add a new disk group DG1 with the same or different specifications
for failure group and other attributes and use RMAN to restore the data.
Answer: C,E,F

Explanation:
Note:
*The md_restore command allows you to restore a disk group from the metadata created
by the md_backup command.
/md_restore Command
Purpose
This command restores a disk group backup using various options that are described in
this section.
/In the restore mode md_restore, it re-create the disk group based on the backup file with
all user-defined templates with the exact configuration as the backuped disk group. There
are several options when restore the disk group
full - re-create the disk group with the exact configuration
nodg - Restores metadata in an existing disk group provided as an input parameter
newdg - Change the configuration like failure group, disk group name, etc..
*The MD_BACKUP command creates a backup file containing metadata for one or more
disk groups. By default all the mounted disk groups are included in the backup file which is
saved in the current working directory. If the name of the backup file is not specified, ASM names
the file AMBR_BACKUP_INTERMEDIATE_FILE.
NO.3 Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two
pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF data file for the
default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupted.
What should you do before executing the commands to restore and recover the data file in
ACCOUNTS_PDB?
A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in ACCOUNTS_PDB.
B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE
IMMEDIATE command.
C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command.
D. Take the USERDATA tablespace offlineinACCOUNTS_PDB.
Answer: D
Oracle echte fragen 1Z0-060 1Z0-060 Schulungsunterlagen
Explanation:
*You can take an online tablespace offline so that it is temporarily unavailable for general use. The
rest of the database remains open and available for users to access data. Conversely, you can bring
an offline tablespace online to make the schema objects within the tablespace available to database
users. The database must be open to alter the availability of a tablespace.
NO.4 Which three are true about the large poolfor anOracle database instance that supports
shared server connections?
A. Allocates memory for RMAN backup and restore operations
B. Allocates memory for shared and private SQL areas
C. Contains a cursor area for storing runtime information about cursors
D. Contains stack space
E. Contains a hash area performing hash joins of tables
Answer: A,B,C
Oracle dumps deutsch 1Z0-060 1Z0-060 PDF Testsoftware
Explanation:
The large pool can provide large memory allocations for the following:
/(B)UGA(User Global Area)for the shared server and the Oracle XA interface (used where
transactions interact with multiple databases)
/Message buffers used in the parallel execution of statements
/(A)Buffers for Recovery Manager (RMAN) I/O slaves
Note:
*large pool
Optional area in the SGA that provides large memory allocations for backup and restore
operations, I/O server processes, and session memory for the shared server and Oracle
XA.
*Oracle XA
An external interface that allows global transactions to be coordinated by a transaction
manager other than Oracle Database.
*UGA
User global area. Session memory that stores session variables, such as logon
information, and can also contain the OLAP pool.
*Configuring the Large Pool
Unlike the shared pool, the large pool does not have an LRU list(not D). Oracle Database
does not attempt to age objects out of the large pool. Consider configuring a large pool if
the database instance uses any of the following Oracle Database features:
*Shared server
In a shared server architecture, the session memory for each client process is included in
the shared pool.
*Parallel query
Parallel query uses shared pool memory to cache parallel execution message buffers.
*Recovery Manager
Recovery Manager (RMAN) uses the shared pool to cache I/O buffers during backup and restore
operations. For I/O server processes, backup, and restore operations, Oracle Database allocates
buffers that are a few hundred kilobytes in size.
NO.5 Which two statements are true about the use of the procedures listed in the
v$sysaux_occupants.move_procedure column?
A. The procedure may be used for some components to relocate component data to the SYSAUX
tablespace from its current tablespace.
B. The procedure may be used for some components to relocate component data from the SYSAUX
tablespace to another tablespace.
C. All the components may be moved into SYSAUX tablespace.
D. All the components may be moved from the SYSAUX tablespace.
Answer: B,D
Oracle originale Fragen 1Z0-060 Prüfungsfrage 1Z0-060 Vorbereitung 1Z0-060 Vorbereitung
Explanation:
V$SYSAUX_OCCUPANTS displays SYSAUX tablespace occupant information.
MOVE_PROCEDURE:Name of the move procedure; null if not applicable
For example, the tables and indexes that were previously owned by the system user can now be
specified for a SYSAUX tablespace. You can query the v$sysaux_occupants view to find the exact
components stored within the SYSAUX tablespace.
NO.6 In your multitenant container database (CDB) containing pluggable databases (PDB), users
complain about performance degradation.
How does real-time Automatic database Diagnostic Monitor (ADDM) check performance
degradation and provide solutions?
A. It collects data from SGA and compares it with a preserved snapshot.
B. It collects data from SGA, analyzes it, and provides a report.
C. It collects data from SGA and compares it with the latest snapshot.
D. It collects data from both SGA and PGA, analyzes it, and provides a report.
Answer: B
Oracle 1Z0-060 1Z0-060 Prüfungsunterlagen 1Z0-060 1Z0-060 antworten
Explanation:
Note: *The multitenant architecture enables an Oracle database to function as a multitenant
container database (CDB) that includes zero, one, or many customer-created pluggable databases
(PDBs). A PDB is a portable collection of schemas, schema objects, and nonschema objects that
appears to an Oracle Net client as a non-CDB. All Oracle databases before Oracle Database 12c were
non-CDBs. *The System Global Area (SGA) is a group of shared memory areas that are dedicated to
an Oracle "instance" (an instance is your database programs and RAM).
*The PGA (Program or Process Global Area) is a memory area (RAM) that stores data and control
information for a single process.
NO.7 Your multitenant container (CDB) containing three pluggable databases (PDBs) is running in
ARCHIVELOG mode. You find that the SYSAUX tablespace is corrupted in the root container.
The steps to recover the tablespace are as follows:
1.Mount the CDB.
2.Close all the PDBs.
3.Open the database.
4.Apply the archive redo logs.
5.Restore the data file.
6.Take the SYSAUX tablespace offline.
7.Place the SYSAUX tablespace offline.
8.Open all the PDBs with RESETLOGS.
NO.8 Your multitenant container (CDB) contains two pluggable databases(PDB), HR_PDB and
ACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called temp01.tmp.
A user issues a query on a table on one of the PDBs and receives the following error:
ERROR at line 1:
ORA-01565: error in identifying file '/u01 /app/oracle/oradata/CDB1 /temp01.tmp'
ORA-27037: unable to obtain file status
Identify two ways to rectify the error.
A. Add a new temp file to the temporary tablespace and drop the temp file that that produced the
error.
B. Shut down the database instance, restore the temp01.tmp file from the backup, and then restart
the database.
C. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and
then bring the temporary tablespace online.
D. Shutdown the database instance, restore and recover the temp file from the backup, and then
open the database with RESETLOGS.
E. Shut down the database instance and then restart the CDB and PDBs.
Answer: C,E
Oracle prüfung 1Z0-060 originale Fragen 1Z0-060 Fragenpool
Explanation:
* Because temp files cannot be backed up and because no redo is ever generated for them, RMAN
never restores or recovers temp files. RMAN does track the names of temp files, but only so that it
can automatically re-create them when needed.
*If you use RMAN in a Data Guard environment, then RMAN transparently converts primary control
files to standby control files and vice versa. RMAN automatically updates file names for data files,
online redo logs, standby redo logs, and temp files when you issue RESTORE and RECOVER.
