Oracle 1z1-064 Exam: Everything You Wanted to Ask
The 1z1-064 exam is the official Oracle exam for Oracle Database 12c: Performance Management and Tuning. Passing it earns you the Oracle Database Performance Management and Tuning credential, which sits at the Expert level. It is also connected to Oracle Certified Expert (OCE), Oracle Database 12c Administrator Certified Professional, so what you learn carries over if you plan to pursue those paths as well. Employers treat the certification as verified proof of skill, which is why structured preparation with 2Pass4sure's practice questions pays off.
The 1z1-064 exam contains 60-85 questions, and the time limit is 120-150. Translate that into a pacing plan before exam day: know roughly how long you can afford per item, flag anything that stalls you, and circle back at the end instead of burning minutes. Two or three full timed sessions in 2Pass4sure's test engine will teach you that rhythm far better than untimed reading ever will.
The passing score for the 1z1-064 exam is 60%-64%, and the official registration fee is USD 245. Remember that a failed attempt means paying that fee again in full for a retake, so treat self-assessment as part of the budget: run 2Pass4sure's practice questions under timed conditions and only book your seat once your scores sit comfortably above the passing bar.
No mandatory prerequisites; recommended experience with Oracle Database 12c administration and basic tuning concepts Eligibility details can change, so before you register, confirm the current requirements on the official exam page: https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=5001&get_params=p_exam_id:1Z0-064.

Oracle Database 12c: Performance Management and Tuning Sample Questions:
Examine the parameters set for your database instance:
You are administrating a database that supports a DSS workload. You make some changes to the sizes of memory components. Consequently, you receive this error:
Which three actions might resolve the issue?
- A. setting the PGA_AGGREGATE_TARGET parameter to 0 and the MEMORY_TARGET parameter to the value of the PGA_AGGREGATE_TARGET parameter
- B. enabling Automatic Memory Management for the database instance
- C. pinning the cursors in the shared pool
- D. setting the value of MEMORY_MAX_TARGET to the value of the SGA_MAX_SIZE parameter
- E. increasing the size of the shared pool
- F. enabling Automatic Shared Memory Management for the database instance
You are administering a database that supports a DSS workload. Automatic Shared Memory Management is enabled for the database instance. Users issue queries to perform large soft operations and complain about degraded performance of the queries. On investigation, you notice that the queries are performing multipass work area executions and the I/O contention on one of the temporary tablespaces is very high.
Which two can be possible resolutions for this issue? (Choose two.)
- A. Increase the value of the PGA_AGGREGATE_LIMIT parameter.
- B. Increase the value of the PGA_AGGREGATE_TARGET parameter.
- C. Enable temporary undo.
- D. Create another temporary tablespace and assign it to users.
- E. Create a temporary tablespace group and assign it to users.
- F. Increase the size of the large pool.
You have been asked to assess if using column store compression (previously known as hybrid columnar compression or HCC) would help improve the performance of queries on some large tables.
Which three aspects should you consider before you choose this compression method? (Choose three.)
- A. Check whether the table blocks are sparsely populated as this will defragment the blocks.
- B. Check whether the table has LOB columns as it will minimize I/O for the queries.
- C. Check whether the table is frequently updated because it will have overhead for insert and update operations.
- D. Check whether the table is frequently queried using full table scans as column store compression only minimizes I/O during full table scans.
- E. Check whether direct path load operations are used to insert rows in the table.
You want to set a priority for the workloads generated by the applications in your database instance such that report-generating tasks are assigned a lower priority.
How would you do this?
- A. by using services that are assigned different priorities with the Resource Manager
- B. by creating an active session pool using the Resource Manager
- C. by using job classes with the Resource Manager
- D. by using services for the applications and creating job classes associated with each service
Examine the partial TKPROF output for an SQL statement:
Which two inferences can definitely be made from this output? (Choose two.)
- A. An uncommitted transaction made a series of updates to the NAME_ID column just before the execution of this query.
- B. Another transaction held a shared lock on the table, thereby causing a significant delay.
- C. Array fetch operations were not performed for this query.
- D. No hard parse was performed for this query.
- E. The number of logical I/Os is almost equal to the number of physical I/Os.
