Which domains make up the 1z0-064 exam?
The Oracle Database 12c: Performance Management and Tuning exam spans 8 domains, and they are not weighted equally. The top areas are Concurrency and Locking, SQL Tuning, Oracle Database Architecture and Performance Fundamentals. Budget your study hours to match those weights; the full domain list is in the outline section further up this page.
Are there official Oracle courses for the 1z0-064 exam?
Yes. Oracle officially recommends these training options for the Oracle Database 12c: Performance Management and Tuning exam:
Training builds the foundation — then measure it with the 120 practice questions for the 1z0-064 exam from Real4test to see how you perform when the clock is running.
Why do professionals take the Oracle 1z0-064 exam?
The 1z0-064 exam is Oracle's official certification test, and passing it earns the Oracle Database 12c credential at the Professional level. In career terms, it is verified proof of skill — the kind that moves you up the shortlist when your company works with Oracle technologies, or when you apply to one that does. The same track also includes Oracle Database 12c Administrator Certified Professional, so this exam can anchor a longer certification plan.
What is the 1z0-064 passing score, and how much is the exam fee?
You pass the Oracle Database 12c: Performance Management and Tuning exam at Approximately 60%, and each attempt costs $245 USD (may vary by region) — fail, and that fee is due again in full for the retake. Treat mock exams as insurance: keep practicing with Real4test until your scores sit comfortably above Approximately 60% twice in a row, then schedule the real 1z0-064 exam.
Can I check your 1z0-064 questions before buying?
Please do. Real4test offers a free demo download for the Oracle Database 12c: Performance Management and Tuning exam — grab it from the product page or leave your email and we will send it over. Purchases come with 365 days of free updates; after that year, extending the update service costs 50% of the original price in your member zone.
How many questions are in the 1z0-064 exam and how long does it run?
The Oracle Database 12c: Performance Management and Tuning exam packs Approximately 60-80 questions into 120 minutes. That ratio leaves almost no room for stalling, so time management is a trained skill, not luck. Our suggestion: rehearse full-length timed sessions in the Real4test engine, learn to park a question and return later, and walk into the 1z0-064 exam with a pacing plan already rehearsed.
What are the eligibility requirements for the 1z0-064 exam?
Recommended: Oracle Database 12c Administrator Certified Professional (commonly including 1Z0-062 and 1Z0-063) or equivalent Oracle DBA experience Since Oracle revises these rules from time to time, confirm the current prerequisites on the official exam page (https://education.oracle.com/oracle-certification-exams) before booking your Oracle Database 12c: Performance Management and Tuning exam.

Oracle Database 12c: Performance Management and Tuning Sample Questions:
Question #1
Your database supports an OLTP workload where a large number of syntactically similar queries are executed. Examine the Instance Efficiency Percentages in the Automatic Workload Repository (AWR) report of the last hour:
Which two inferences can be drawn from the report?
A. Cursors are not getting shared in the library cache.
B. The optimizer is waiting for resources during parsing of the queries.
C. The CPU is spending more time on pinning cursors in the library cache.
D. The database buffer cache is undersized and is causing contention.
Question #2
A senior DBA asks you to decrease the values of the connect_time_scale and think_time_scale replay processing parameters to 50 to preprocess the workload for replay.
What three could be reasons for this change? (Choose three.)
A. to reduce the elapsed time between two successive user calls from a session.
B. to decrease the number of concurrent users during replay
C. to increase the number of concurrent users during replay
D. to reduce the time of replay
E. to decrease the wait for a query, caused by noncommitted transactions
Question #3
In your database, the measured 99th percentile value is used as the maximum value. You set a warning threshold level of 110% of maximum trigger as an alert.
What is the outcome? (Choose the best answer.)
A. It generates an alert when an observed metric is 110% of the 99th percentile value as measured over the moving window baseline.
B. It generates an alert when an observed metric is 99% of the 99th percentile value as measured over the moving window baseline.
C. It generates an error because the warning threshold cannot exceed 100%.
D. It generates an alert when 1 in 100 observations for an observed metric exceeds the 99th percentile value as measured over the fixed baseline.
E. It generates an error because the percentage of maximum threshold cannot be set with a significance-level threshold value.
Question #4
Which two statements are true about DB time in V$SYS_TIME_MODEL? (Choose two.)
A. DB time cannot exceed the maximum number of concurrent sessions multiplied by the actual elapsed time for each session.
B. DB time includes the time spent on client processes and background processes.
C. Reducing DB time allows a database instance to support more user requests by using the same resources.
D. DB time is always greater than or equal to the DB CPU time.
E. DB time cannot exceed the total elapsed time (walk clock time) since the database instance started.
Question #5
Examine the parameters:
Your database supports a mixed workload and users have dedicated server connections. Users complain about the increased response time of a few queries that are performing large sort operations. On investigation, you notice an increase in the number of multipass work area executions and a high number of direct path write wait events.
Which two actions could improve the performance? (Choose two.)
A. increasing the value of the SORT_AREA_SIZE parameter
B. using parallel hint in queries performing large sort operations
C. enabling Automatic Memory Management for the instance
D. increasing the size of the default temporary tablespace
E. enabling Automatic Shared Memory Management for the instance
F. increasing the value of the PGA_AGGREGATE_TARGET parameter
