- A. to analyze problems in an unresponsive database, which requires a database restart
- B. to determine the segments on which waits are occurring when the database has a high number of buffer busy waits
- C. to determine if the SGA_TARGET parameter value needs to be changed when your database is configured for Automatic Shared Memory Management and additional physical memory is added to the database server

- E. to determine whether SQL profiling needs to be done to tune SQL statements transparently without requiring any change to the application code
Correct Answer: A,D,E 🗳️
You are administering a database that supports an OLTP workload. RESULT_CACHE_MODE is set to the default value and a result cache is configured for the instance. Multiple sessions execute syntactically similar queries without dblinks, containing functions and expressions, on tables with no DML activity. Some users complain about poor performance of these queries.
You investigate and find that the queries are frequently performing physical I/O, even though the results fetched by the queries are similar.
Which two actions do you recommend to overcome the problem affecting these queries? (Choose two.)
- A. Set the RESULT_CAHCE_MODE parameter to FORCE for the instance.
- B. Configure the KEEP pool and cache the queried tables used in the KEEP pool.
- C. Set the RESULT_CACHE_REMOTE_EXPIRATION parameter to a nonzero value.
- D. Use the result cache hint in the queries.
- E. Use bind variables for similar queries instead of literals.
Correct Answer: A,D 🗳️
In your database, the locally managed tablespace, USERS, has the default space usage alert set to 85% for the warning level and 97% for the critical level.
Which two statements are true? (Choose two.)
- A. Alert settings for the warning and critical levels must be disabled before taking the USERS tablespace offline.
- B. Alerts are recorded in both Oracle Enterprise Manager Cloud Control and DBA_OUTSTANDING_ALERTS only when the critical threshold is exceeded.
- C. Alerts that are triggered are automatically recorded in DBA_ALERT_HISTORY after they are cleared.
- D. Alerts are triggered when the space usage reaches the warning level, again when it reaches the critical level, and yet again when the space usage falls below the critical level.
Correct Answer: A,B 🗳️
Which two statements are true about wait events?
- A. A single resource wait event may be recorded as multiple waits, depending on the number of session timeouts during that wait.
- B. Wait event statistics are cumulatively collected only at the instance level.
- C. Wait event countries are incremented by the server process that waits.
- D. A wait event can be defined in multiple wait classes.
- E. Wait events for an instance include statistics for both background and foreground processes.
