Oracle시험 1Z0-060시험자료 1Z0-060 IT자격증시험자료 1Z0-060 IT자격증
Explanation:
You cannot roll back a TRUNCATE TABLE statement, nor can you use a FLASHBACK TABLE statement
to retrieve the contents of a table that has been truncated.
NO.2 Identify two situations in which the alert log file is updated.
A. Running a query on a table returns ORA-600: Internal Error.
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.
E. Rebuilding an index using ALTER INDEX . . . REBUILD fails with an ORA-01578: ORACLE data block
corrupted (file # 14, block # 50) error.
Answer: A,E
Oracle 1Z0-060시험 1Z0-060시험 1Z0-060자격증 1Z0-060최신버전덤프 1Z0-060덤프자료
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.3 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.4 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 1Z0-060 IT국제자격증 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.5 The trace files may be aggregated by using the trcess utility.
NO.6 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
Oracle자격증 1Z0-060자료 1Z0-060 dump 1Z0-060
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.7 Identify three benefits of Unified Auditing.
A. Decreased use of storage to store audit trail rows in the database.
B. It improves overall auditing performance.
C. It guarantees zero-loss auditing.
D. The audit trail cannot be easily modified because it is read-only.
E. It automatically audits Recovery Manager (RMAN) events.
Answer: A,B,E
Oracle 1Z0-060 1Z0-060최신버전덤프 1Z0-060 pdf
Explanation:
A: Starting with 12c, Oracle has unified all of the auditing types into one single unit called Unified
auditing. You don't have to turn on or off all of the different auidting types individually and as a
matter of fact auditing is enabled by default right out of the box. The AUD$ and FGA$ tables have
been replaced with one single audit trail table. All of the audit data is now stored in Secure Files
table thus improving the overall management aspects of audit data itself.
B: Further the audit data can also be buffered solving most of the common performance related
problems seen on busy environments.
E: Unified Auditing is able to collect audit data for Fine Grained Audit, RMAN, Data Pump, Label
Security, Database Vault and Real Application Security operations.
Note:
* Benefits of the Unified Audit Trail
The benefits of a unified audit trail are many: / (B) Overall auditing performance is greatly improved.
The default mode that unified audit works is Queued Write mode. In this mode, the audit records
are batched in SGA queue and is persisted in a periodic way. Because the audit records are written
to SGA queue, there is a significant performance improvement.
/ The unified auditing functionality is always enabled and does not depend on the initialization
parameters that were used in previous releases
/ (A) The audit records, including records from the SYS audit trail, for all the audited components of
your Oracle Database installation are placed in one location and in one format, rather than your
having to look in different places to find audit trails in varying formats. This consolidated view
enables auditors to co-relate audit information from different components. For example, if an error
occurred during an INSERT statement, standard auditing can indicate the error number and the SQL
that was executed. Oracle Database Vault-specific information can indicate whether this error
happened because of a command rule violation or realm violation. Note that there will be two audit
records with a distinct AUDIT_TYPE. With this unification in place, SYS audit records appear with
AUDIT_TYPE set to Standard Audit.
/ The management and security of the audit trail is also improved by having it in single audit trail.
/ You can create named audit policies that enable you to audit the supported components listed at
the beginning of this section, as well as SYS administrative users. Furthermore, you can build
conditions and exclusions into your policies.
*Oracle Database 12c Unified Auditing enables selective and effective auditing inside the Oracle
database using policies and conditions. The new policy based syntax simplifies management of
auditing within the database and provides the ability to accelerate auditing based on conditions.
*The new architecture unifies the existing audit trails into a single audit trail, enabling simplified
management and increasing the security of audit data generated by the 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
Oracle자격시험 1Z0-060자격증신청 1Z0-060시험후기
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
