1Z0-997-26 Databases Practice Question
An enterprise application uses an Oracle Autonomous Transaction Processing database and encounters intermittent application-level timeouts during peak concurrency spikes. Upon investigating, you notice that queued statements are waiting due to resource limits. Which Autonomous Database feature should you adjust to manage concurrency and statement queuing behavior?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Consumer groups and resource management rules via DBMS_RESOURCE_MANAGER or resource profile settings
Autonomous Database allows managing resource management rules and consumer groups, including setting parameters via DBMS_RESOURCE_MANAGER or adjusting CPU/concurrency profiles.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The physical memory size of the OCI Compute host instance running the application
Why it's wrong here
Incorrect. Application compute memory does not dictate database statement execution queues.
- ✗
Linux kernel swappiness parameters on the database host
Why it's wrong here
Incorrect. Swappiness is a low-level OS memory setting, not an Autonomous Database concurrency control.
- ✗
OCI Virtual Cloud Network security list packet drop thresholds
Why it's wrong here
Incorrect. Security lists do not manage database concurrency or statement queuing.
- ✓
Consumer groups and resource management rules via DBMS_RESOURCE_MANAGER or resource profile settings
Why this is correct
Correct. Adjusting resource consumer groups and parallelism controls how queries are queued and executed under high concurrency.
