Oracle Database 23ai Administration Associate 1Z1-182 Prüfungsfragen mit Lösungen (Q79-Q84):

79. Frage
Which three statements are true about dynamic performance views?

A. They are owned by the SYSTEM user.
B. V$FIXED_TABLE can be queried to display the names of all dynamic performance views.
C. Read consistency is not guaranteed.
D. Data displayed by querying dynamic performance views is derived from metadata in the data dictionary.
E. They can be queried only when the database is open.

Antwort: B,C,D

Begründung:
A .True. V$ views reflect real-time memory data, not consistent snapshots.
B .True. V$FIXED_TABLE lists all V$ views.
C .True. Data comes from memory structures and data dictionary metadata.
D .False. Owned by SYS, not SYSTEM.
E .False. Some V$ views are accessible in MOUNT state.

80. Frage
You execute the SHUTDOWN ABORT command. Which two statements are true?

A. Subsequent instance startup performs media recovery.
B. Data files are closed normally.
C. Uncommitted transactions are not rolled back by the shutdown.
D. A checkpoint is written.
E. Subsequent instance startup performs instance recovery.

Antwort: C,E

Begründung:
A .False. No checkpoint occurs with ABORT.
B .False. Instance recovery, not media recovery, is needed.
C .True. Crash recovery rolls back uncommitted changes on startup.
D .False. Files aren't closed cleanly with ABORT.
E .True. Shutdown doesn't roll back; recovery does.

81. Frage
Which two statements describe how Optimizer Statistics are collected?

A. Optimizer Statistics can be manually collected at multiple levels using DBMS_STATS.GATHER_*_STATS PL/SQL procedures.
B. Optimizer Statistics are collected automatically by an automatic maintenance job that runsduring predefined maintenance windows.
C. Optimizer Statistics are collected by the Statistics Advisor.
D. Optimizer Statistics are collected automatically by Automatic Workload Repository (AWR) Snapshot.
E. Optimizer Statistics are collected in real-time as data is inserted, deleted, or updated.

Antwort: A,B

Begründung:
Optimizer Statistics drive the cost-based optimizer's query plans. Let's dissect each option:
A . Optimizer Statistics are collected automatically by an automatic maintenance job that runs during predefined maintenance windows.
True. Oracle 23ai uses the AutoTask framework to gather stats automatically during maintenance windows (e.g., nightly 10 PM-2 AM). The GATHER_STATS_PROG job, managed by DBMS_AUTO_TASK_ADMIN, collects stats for stale or missing objects.
Mechanics:Controlled by STATISTICS_LEVEL=TYPICAL (default) and the DEFAULT_MAINTENANCE_PLAN. It prioritizes objects with >10% changes (stale stats) or no stats.
Practical Use:Ensures stats are current without manual intervention, critical for dynamic workloads.
Edge Case:Disabled if STATISTICS_LEVEL=BASIC or the job is manually disabled via DBMS_AUTO_TASK_ADMIN.DISABLE.
B . Optimizer Statistics are collected in real-time as data is inserted, deleted, or updated.
False. Stats aren't updated in real-time; this would be too resource-intensive. Instead, Oracle tracks changes (e.g., via DBA_TAB_MODIFICATIONS) and updates stats periodically via AutoTask or manually. Real-time stats exist in 23ai for specific cases (e.g., GATHER_TABLE_STATS with REAL_TIME_STATS), but it's not the default.
Why Incorrect:Real-time collection would degrade performance for OLTP systems, contradicting Oracle's batch approach.
C . Optimizer Statistics can be manually collected at multiple levels using DBMS_STATS.GATHER_*_STATS PL/SQL procedures.
True. The DBMS_STATS package offers granular control: GATHER_TABLE_STATS, GATHER_SCHEMA_STATS, GATHER_DATABASE_STATS, etc., allowing stats collection for tables, schemas, or the entire database.
Mechanics:Example: BEGIN DBMS_STATS.GATHER_TABLE_STATS('HR', 'EMPLOYEES'); END;. Options like ESTIMATE_PERCENT and DEGREE fine-tune the process.
Practical Use:Used for immediate stats updates post-DML or for custom schedules outside maintenance windows.
Edge Case:Overuse can lock stats (e.g., FORCE=TRUE), requiring careful management.
D . Optimizer Statistics are collected by the Statistics Advisor.
False. The Statistics Advisor (new in 23ai) analyzes and recommends stats improvements but doesn't collect them. Collection is still via DBMS_STATS or AutoTask.
Why Incorrect:It's a diagnostic tool, not an executor.
E . Optimizer Statistics are collected automatically by Automatic Workload Repository (AWR) Snapshot.
False. AWR snapshots capture performance metrics (e.g., wait times), not optimizer stats. Stats collection is a separate process via AutoTask or manual commands.
Why Incorrect:AWR and stats collection serve distinct purposes-monitoring vs. optimization.

82. Frage
In which two ways would you disable timing information collected for wait events and much of the performance monitoring capability of the database?

A. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.LEVEL(BASIC).
B. By setting the STATISTICS_LEVEL parameter to BASIC.
C. By setting the TIMED_STATISTICS_LEVEL system parameter to FALSE.
D. By setting the TIMED_STATISTICS system parameter to FALSE.
E. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.DISABLE(TRUE).

Antwort: B,D

Begründung:
A .True. TIMED_STATISTICS = FALSE disables timing data collection.
B .False. No such procedure exists.
C .False. No TIMED_STATISTICS_LEVEL parameter exists.
D .True. STATISTICS_LEVEL = BASIC disables most performance monitoring.
E .False. No such procedure exists.

83. Frage
What are Oracle Database Metrics?

A. Oracle Database Metrics monitor performance using thresholds to generate alerts.
B. Oracle Database Metrics are a set of statistics built in Oracle Enterprise Manager Cloud Control and used for automation.
C. Oracle Database Metrics are part of Oracle Enterprise Manager Cloud Control's Notification system used to email alerts.
D. Oracle Database Metrics are a set of measured statistics per unit of time (per second), transaction, or sessions that are used to evaluate performance.
E. Oracle Database Metrics are part of the Oracle Database Notification system to email information about major database events.

Antwort: A,D

Begründung:
A .True. Metrics (e.g., V$SYSMETRIC) use thresholds for alerts.
B .False. Metrics aren't tied to email notifications directly.
C .True. Metrics measure rates (e.g., IOPS, transactions/sec).
D .False. EMCC uses metrics, but they're DB-level, not EM-specific.
E .False. Metrics exist in the DB, not just EMCC.
