B. Inserting a value into a table returns ORA-01722: invalid number.
C. Creating a table returns ORA-00955: name us already in used by an existing objects.
D. Inserting a value into a table returns ORA-00001: unique constraint (SYS.OK_TECHP) violated.

Answer: A,E

Explanation:
The alert log is a chronological log of messages and errors, and includes the following items:
*All internal errors (ORA-600), block corruption errors (ORA-1578), and deadlock errors (ORA-60)
that occur
*Administrative operations, such as CREATE, ALTER, and DROP statements and STARTUP ,
SHUTDOWN, and ARCHIVELOG statements
*Messages and errors relating to the functions of shared server and dispatcher processes
*Errors occurring during the automatic refresh of a materialized view
*The values of all initialization parameters that had nondefault values at the time the database and
instance start
Note:
*The alert log file (also referred to as the ALERT.LOG) is a chronological log of messages and errors
written out by an Oracle Database. Typical messages found in this file is: database startup,
shutdown, log switches, space errors, etc. This file should constantly be monitored to detect
unexpected messages and corruptions.

NO.2 Your multitenant container database (CDB) contains a pluggable database, HR_PDB. The
default permanent tablespace in HR_PDB is USERDATA. The container database (CDB) is open and
you connect RMAN.
You want to issue the following RMAN command:
RMAN > BACKUP TABLESPACE hr_pdb:userdata; Which task should you perform before issuing the
command?
A. Place the root container in ARHCHIVELOG mode.
B. Take the user data tablespace offline.
C. Place the root container in the nomount stage.
D. Ensure that HR_PDB is open.
Answer: A

NO.3 You execute the following piece of code with appropriate privileges: User SCOTT has been
granted the CREATE SESSION privilege and the MGR role.
Which two statements are true when a session logged in as SCOTT queries the SAL column in the
view and the table?
A. Data is redacted for the EMP .SAL column only if the SCOTT session does not have the MGR role
set.
B. Data is redacted for EMP .SAL column only if the SCOTT session has the MGR role set.
C. Data is never redacted for the EMP_V.SAL column.
D. Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.
E. Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role
set.
Answer: A,C

Oracle教育   1Z0-060認証試験   1Z0-060教本
Explanation:
Note:
*DBMS_REDACT.FULL completely redacts the column data.
*DBMS_REDACT.NONE applies no redaction on the column data. Use this function for development
testing purposes. LOB columns are not supported.
*The DBMS_REDACT package provides an interface to Oracle Data Redaction, which enables you to
mask (redact) data that is returned from queries issued by low-privileged users or an application.
*If you create a view chain (that is, a view based on another view), then the Data Redaction policy
also applies throughout this view chain. The policies remain in effect all of the way up through this
view chain, but if another policy is created for one of these views, then for the columns affected in
the subsequent views, this new policy takes precedence.

NO.4 Your database has the SRV1 service configured for an application that runs on middle-tier
application server. The application has multiple modules. You enable tracing at the service level by
executing the following command:
SQL > exec DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE ('SRV1');
The possible outcome and actions to aggregate the trace files are as follows:
1.The command fails because a module name is not specified.
2.A trace file is created for each session that is running the SRV1 service.
3.An aggregated trace file is created for all the sessions that are running the SRV1 service.

NO.5 You notice a high number of waits for the db file scattered read and db file sequential read
events in the recent Automatic Database Diagnostic Monitor (ADDM) report. After further
investigation, you find that queries are performing too many full table scans and indexes are not
being used even though the filter columns are indexed.
Identify three possible reasons for this.
A. Missing or stale histogram statistics
B. Undersized shared pool
C. High clustering factor for the indexes
D. High value for the DB_FILE_MULTIBLOCK_READ_COUNT parameter
E. Oversized buffer cache
Answer: A,C,D

Oracle vue   1Z0-060講座   1Z0-060問題集   1Z0-060学習   1Z0-060入門
Explanation:
D: DB_FILE_MULTIBLOCK_READ_COUNT is one of the parameters you can use to minimize I/O
during table scans. It specifies the maximum number of blocks read in one I/O operation during a
sequential scan. The total number of I/Os needed to perform a full table scan depends on such
factors as the size of the table, the multiblock read count, and whether parallel execution is being
utilized for the operation.

NO.6 The trace files may be aggregated by using the trcess utility.

NO.7 Which three statements are true about Oracle Data Pump export and import operations?
A. You can detach from a data pump export job and reattach later.
B. Data pump uses parallel execution server processes to implement parallel import.
C. Data pump import requires the import file to be in a directory owned by the oracle owner.
D. The master table is the last object to be exported by the data pump.
E. You can detach from a data pump import job and reattach later.
Answer: A,B,D

Oracleテスト   1Z0-060   1Z0-060
Explanation:
B: Data Pump can employ multiple worker processes, running in parallel, to increase job
performance.
D: For export jobs, the master table records the location of database objects within a dump file set.
/ Export builds and maintains the master table for the duration of the job. At the end of an export
job, the content of the master table is written to a file in the dump file set.
/ For import jobs, the master table is loaded from the dump file set and is used to control the
sequence of operations for locating objects that need to be imported into the target database.

NO.8 In your database, you want to ensure that idle sessions that are blocking active are
automatically terminated after a specified period of time.
How would you accomplish this?
A. Setting a metric threshold
B. Implementing Database Resource Manager
C. Enabling resumable timeout for user sessions
D. Decreasing the value of the IDLE_TIME resource limit in the default profile
Answer: D

Explanation:
An Oracle session is sniped when you set the idle_time parameter to disconnect inactive sessions.
(It's only like sniping on ebay in that a time is set for an action to occur.)
Oracle has several ways to disconnect inactive or idle sessions, both from within SQL*Plus via
resources profiles (connect_time, idle_time), and with the SQL*net expire time parameter. Here are
two ways to disconnect an idle session:
Set the idle_time parameter in the user profile Set the sqlnet.ora parameter expire_time
