- A
The procedure uses `DBMS_OUTPUT.PUT_LINE`, which should be replaced with `RAISE EXCEPTION`.
Why wrong: `RAISE EXCEPTION` is for errors, not output.
- B
The procedure uses `DBMS_OUTPUT.PUT_LINE`, which is supported natively in PostgreSQL.
Why wrong: PostgreSQL does not have `DBMS_OUTPUT`.
- C
The procedure uses `DBMS_OUTPUT.PUT_LINE`, which should be replaced with `RAISE NOTICE` in PostgreSQL.
Correct. `DBMS_OUTPUT.PUT_LINE` is Oracle-specific; in PostgreSQL, use `RAISE NOTICE`.
- D
The procedure must be rewritten in Python using PL/Python.
Why wrong: Unnecessary; use PL/pgSQL with `RAISE`.

PCDOE Migrate Database Solutions Practice Question
This PCDOE practice question tests your understanding of migrate database solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is performing a heterogeneous migration from Oracle to Cloud SQL for PostgreSQL using Ora2Pg. During testing, they find that a stored procedure using Oracle's PL/SQL `DBMS_OUTPUT.PUT_LINE` does not execute after conversion. What is the most likely issue, and how should it be resolved?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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
✓
The procedure uses `DBMS_OUTPUT.PUT_LINE`, which should be replaced with `RAISE NOTICE` in PostgreSQL.
Ora2Pg converts PL/SQL to PL/pgSQL. `DBMS_OUTPUT.PUT_LINE` in Oracle is equivalent to `RAISE NOTICE` in PostgreSQL. Ora2Pg may not automatically convert all procedural constructs, requiring manual review and adjustment.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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 procedure uses `DBMS_OUTPUT.PUT_LINE`, which should be replaced with `RAISE EXCEPTION`.
Why it's wrong here
`RAISE EXCEPTION` is for errors, not output.
- ✗
The procedure uses `DBMS_OUTPUT.PUT_LINE`, which is supported natively in PostgreSQL.
Why it's wrong here
PostgreSQL does not have `DBMS_OUTPUT`.
- ✓
The procedure uses `DBMS_OUTPUT.PUT_LINE`, which should be replaced with `RAISE NOTICE` in PostgreSQL.
Why this is correct
Correct. `DBMS_OUTPUT.PUT_LINE` is Oracle-specific; in PostgreSQL, use `RAISE NOTICE`.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
- ✗
The procedure must be rewritten in Python using PL/Python.
Why it's wrong here
Unnecessary; use PL/pgSQL with `RAISE`.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Trap categories for this question
Command / output trap
`RAISE EXCEPTION` is for errors, not output.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
Visual reference
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PCDOE ACL questions on filtering logic and placement.
