Everything Candidates Ask About Oracle Database 12c: Performance Management and Tuning
The 1z1-064 exam, officially titled Oracle Database 12c: Performance Management and Tuning, is the qualifying exam for the Oracle Database Performance Management and Tuning certification, which sits at the Expert level. Earning it shows employers that you have the skills the credential stands for, and it is a solid step forward on a Oracle career path. It also connects to Oracle Certified Expert (OCE), Oracle Database 12c Administrator Certified Professional, so the effort you put in now keeps paying off as you advance.
The 1z1-064 exam gives you 60-85 questions to complete within 120-150. Do the math before exam day: divide the total time by the question count to set a steady per-question pace, and flag any item that stalls you so you can return to it after securing the easier points. The most reliable way to build that rhythm is a full timed practice test under the same limit, which is exactly what TestSimulate's test engines are designed for.
The passing score for Oracle Database 12c: Performance Management and Tuning is 60%-64%, and the official registration fee is USD 245.

For the full domain and subtopic breakdown, see the Exam Topics section above — that is the outline your TestSimulate practice questions are mapped to.
Oracle Database 12c: Performance Management and Tuning Sample Questions:
Question 1
Your database supports a mixed workload. The ERP application creates short sessions and performs small, random I/Os; the REPORTING application executes long-running DSS queries.
You want to set a priority for the workload generated by the ERP application and optimize resource usage for them.
Which three objectives can be achieved by the Resource Manager? (Choose three.)
A. limiting the amount of undo generated by operations performed by sessions created by the ERP application
B. limiting the physical I/O performed by the sessions or users of the ERP application that are connected to the database
C. creating two resource plans with resource limits defined for the workload generated by the applications and automatically changing resource plans based on the workload
D. limiting the amount of time that a session is idle and blocking other sessions of the ERP application
E. allocating a lower percentage of CPU to sessions used by the REPORTING apnplication than to those used by the ERP application
Question 2
You plan to upgrade your production database from Oracle Database 11g to 12c and also to introduce new objects to the database. You also want to upgrade the hardware. You have already created a test system with the upgrades to be made to the production database. As part of the testing, you want to:
analyze and compare the overall database workload with concurrency and transaction characteristics find SQL statements that might get regressed because of the upgrade analyze execution plans for SQL statements for which performance might get regressed analyze the impact of new schema objects on database performance Which two tools would you recommend to achieve the objective? (Choose two.)
A. Database Replay
B. Automatic Workload Repository (AWR) compare periods report
C. SQL Tuning Advisor
D. Automatic Database Diagnostic Monitor (ADDM) compare periods report
E. SQL Access Advisor
F. SQL Performance Analyzer
Question 3
Your database supports a mixed workload. In an application, multiple complex queries with functions and expressions are executing. You want to analyze the queries that are currently cached in the library cache to receive recommendations about the usage of indexes and materialized views.
What should you do to achieve this? (Choose the best answer.)
A. Capture the workload in an STS and submit to SQL Tuning Advisor for recommendations.
B. Create an STS for the queries cached in the library cache and submit it as an input to SQL Access Advisor.
C. Create an STS for the queries cached in the library cache and submit it as an input to SQL Performance Analyzer.
D. Create an STS for the queries cached in the library cache and submit it as an input to SQL Tuning Advisor.
Question 4
Your database supports an OLTP workload.
An application frequently performs update operations on an indexed column of a table; some bulk delete and insert operations are also performed.
The table is created in a locally managed tablespace with manual segment space management.
A user complains about poor response time when querying the table.
The queries mostly perform index range scans.
You notice a high number of buffer busy waits and contention on segment headers.
Which three would you investigate further to diagnose the poor response time?
A. Chick whether the indexes have only a few entries per block.
B. Check for freelist contention.
C. Check the size of the shared pool.
D. Check the size of the large pool.
E. Check table blocks for migrated or chained rows.
Question 5
Which three actions should you perform to reduce shared pool fragmentation and avoid the "ORA-04031: unable to allocate .... bytes of shared memory" error for the shared pool? (Choose three.)
A. Use DBMS_SHARED_POOL.KEEP to keep the SYS.STANDARD, SYS.DBMS_STANDARD, and SYS.DIUTIL packages and frequently executed compiled triggers.
B. Standardize the type, size, and naming conventions for bind variables and spacing conventions for SQL statements and PL/SQL blocks.
C. Use more anonymous procedures.
D. Identify the packages or procedures that are causing the "ORA-04031:unable to allocate....bytes of shared memory" error and use the DBMS_SHARED_POOL.KEEP to keep them in the shared pool.
E. Configure the Server Result Cache.
F. Configure shared server mode.
