Question 1 of 10

1. Question
A developer on your team is building a new application module and needs to create a custom lookup type. They want this lookup to be available only within their specific application, not shared across the entire E-Business Suite installation. Considering maintenance and upgrade best practices, which approach should you recommend for defining this lookup?
- Define it in the Application Developer responsibility using the Application Utilities Lookups form, ensuring the 'Application' field is set to their specific product.
- Define it directly in the database by inserting records into the FND_LOOKUP_VALUES table with the appropriate APPLICATION_ID.
- Use the System Administrator responsibility to create a new Set of Books, as lookups are always tied to a primary ledger.
- Create a custom database table and form to manage the values, bypassing the standard lookup framework entirely.
Correct

The correct method is to use the standard Application Utilities Lookups form within the Application Developer responsibility. Setting the ‘Application’ field scopes the lookup to that specific product, making it portable and upgrade-safe. Direct database inserts (Option B) are unsupported and risky. Option C is irrelevant to lookups, and Option D violates the principle of using standard, maintainable frameworks.

Question 2 of 10

2. Question
You are reviewing a performance issue where a key transaction form is loading slowly. Upon investigation, you find a custom PL/SQL library attached to the form contains a SQL query that performs a full table scan on a large transaction table every time a record is queried. What is the most effective first step you should take to diagnose and potentially resolve this performance bottleneck?
- Run the TKPROF utility to generate a SQL trace file for the form session and analyze the execution plan of the problematic query.
- Immediately add a hint to force the use of an index in the custom PL/SQL code and redeploy the library.
- Increase the SGA_TARGET parameter in the database initialization file to provide more memory for caching.
- Recommend that users reduce the number of records they query at one time to lessen the load on the system.
Correct

The correct first step is systematic diagnosis using TKPROF and analyzing the execution plan. This will confirm if an index is missing or misused, guiding the proper fix (e.g., creating an index or rewriting the query). Adding hints (Option B) without understanding the root cause can be dangerous. Option C addresses a symptom, not the cause, and Option D is a workaround, not a solution.

Question 3 of 10

3. Question
Your company is implementing a new approval hierarchy for purchase requisitions that requires a dynamic, rules-based approval path. The standard ‘Approval Groups’ functionality is too rigid for your needs. Which two Oracle Workflow components must you primarily configure to build this custom, rules-based approval process? (Choose the best single answer that combines both critical components).
- An Item Type with its associated Attributes, and a Process Definition built using the Workflow Builder.
- A custom database table to store approval rules and a concurrent program to evaluate them.
- A set of Personalization rules on the Requisitions form and a custom Java bean.
- The Approval Management Engine (AME) rules and the System Administrator's Profile Options.
Correct

Oracle Workflow is the core engine for custom approval processes. The fundamental building blocks are an Item Type (the container) with Attributes (data elements), and a Process Definition (the visual flowchart of the approval steps). Option B bypasses the supported workflow engine. Option C uses the wrong tool (personalization) for a process flow. Option D refers to AME, which is a separate, rules-based engine often used *with* workflows, but the question specifies building within a custom workflow context.

Question 4 of 10

4. Question
During a monthly patching cycle, you apply a new RUP (Release Update Pack) to your EBS instance. After the application is brought back online, users report that a critical, custom-built report now returns an error stating a database view is invalid. What is the most likely cause and the appropriate immediate action?
- The patch updated underlying application tables, and the custom view's defining query references columns that have been modified or obsoleted. You should analyze the view's SQL against the new table structures.
- The patch corrupted the database data dictionary. You need to restore the entire database from the pre-patch backup.
- The application tier services were not bounced in the correct order. You should restart all services starting with the Admin Server.
- User permissions were inadvertently revoked by the patch. You must regrant SELECT privileges on the base tables to the report schema.
Correct

Oracle EBS patches can change table structures. A custom view that uses SELECT * or references specific columns that were altered will become invalid. The correct action is to analyze the view definition (DBA_VIEWS.TEXT) against the new table definition (DESC
). Option B is a drastic overreaction. Option C is unrelated to a database object validity error. Option D is possible but less likely than a structural change from a RUP.

Question 5 of 10

5. Question
You need to create a simple, auditable log of every time a specific value in the ‘Suppliers’ form is changed. The log must capture the old value, new value, who changed it, and when. You want to minimize impact on the standard form’s performance and maintenance. What is the recommended method?
- Create a database trigger on the underlying base table (e.g., PO_VENDORS) that inserts a record into a custom logging table on UPDATE.
- Modify the form's PRE-UPDATE and POST-UPDATE triggers in Form Builder to write to a file on the application server.
- Create a concurrent program that runs hourly to scan the table for changes and populate the log.
- Use the standard AuditTrail functionality within Oracle E-Business Suite by enabling auditing on the specific column.
Correct

Oracle EBS provides a standard, supported AuditTrail (also called Fine-Grained Auditing) feature specifically for this purpose. It can be configured at the column level, captures the required metadata (who/when), and is managed through the application (not direct DB triggers). Option A, while functional, is a custom modification that may not be upgrade-safe. Option B is inefficient and deals with server files. Option C is not real-time.

Question 6 of 10

6. Question
A business user asks you to modify the ‘Invoice Overview’ screen to display a new, non-database field that calculates a discount rate based on values in two other fields. They want this change deployed quickly without a full code migration. Which tool provides the most appropriate balance of capability, speed, and adherence to Oracle’s support guidelines?
- Oracle Forms Personalization
- Modifying the PLL library file using Form Builder and deploying it to all servers
- Creating a custom OA Framework page to replace the entire invoice screen
- Adding a virtual column to the underlying database view and regenerating the form
Correct

Oracle Forms Personalization is the recommended, supported method for making minor UI adjustments, adding calculated fields, and simple logic without modifying the base Oracle code. It is quick, stored in the database, and upgrade-safe. Option B is a direct code modification, which is unsupported and complicates upgrades. Option C is overkill for a single field. Option D involves backend changes for a front-end display need.

Question 7 of 10

7. Question
You are designing an integration where an external system needs to create sales orders in EBS nightly. The volume is approximately 500 orders per run. Which interface is the most robust and efficient method for this programmatic creation?
- Use the Order Management Open Interfaces (OMOI), specifically populating the OE_HEADERS_IFACE_ALL and OE_LINES_IFACE_ALL tables, then running the Order Import concurrent program.
- Simulate user input by writing a script that uses Oracle Forms in headless mode to navigate and populate the Sales Order form.
- Write direct INSERT statements into the base tables OE_ORDER_HEADERS_ALL and OE_ORDER_LINES_ALL.
- Use the standard 'Import Sales Orders' functionality in the Order Management superuser menu, which expects a CSV file upload.
Correct

The Order Management Open Interface (OMOI) is the standard, supported, and batch-oriented API for creating sales orders programmatically. It handles validation, derivation, and integration with other modules (like Inventory, Shipping) correctly. Option B is fragile and not suitable for batch processing. Option C bypasses all business logic and is highly unsupported. Option D is a manual, user-driven process, not an automated interface.

Question 8 of 10

8. Question
When registering a custom concurrent program executable, you must define its execution method. Your program is a Java class (.class file) that requires specific JVM arguments. Which execution method should you choose, and where would you configure the JVM arguments?
- Execution Method: 'Java Concurrent Program'. Configure the JVM arguments in the 'Execution Options' field of the executable definition.
- Execution Method: 'Host'. Write a shell script that calls Java with the arguments, and register the shell script as the executable.
- Execution Method: 'PL/SQL Stored Procedure'. Create a PL/SQL wrapper that uses DBMS_JAVA to run the class with arguments.
- Execution Method: 'Oracle Reports'. Rebuild the logic as an Oracle Report, as Java programs are not supported as concurrent programs.
Correct

Oracle EBS supports ‘Java Concurrent Program’ as a native execution method. The ‘Execution Options’ field in the executable definition is specifically designed for passing arguments to the Java Virtual Machine (e.g., -Xmx256m -Dcustom.property=value). Option B works but adds unnecessary complexity and an extra layer. Option C is an inefficient and non-standard workaround. Option D is incorrect; Java concurrent programs are fully supported.

Question 9 of 10

9. Question
After cloning your EBS environment from Production to a new TEST instance, users cannot log in. They enter their credentials but are immediately returned to the login screen without an error message. The database listener and application services are confirmed to be running. What is the most probable cause?
- The profile option 'Sign-on: Forgotten Password Functionality' is set incorrectly, blocking all logins.
- The context file (e.g., TEST_.xml) still contains production-specific values, such as the port number for the Forms servlet or database connect string.
- The user accounts are locked in the new TEST database. You need to unlock them using the System Administrator responsibility.
- The web server's httpd.conf file has a deny rule for the TEST network subnet.
Correct

A silent return to the login page is a classic symptom of an incorrect application tier configuration after a clone, often due to an outdated context file. If the context file points to the old production ports or database details, the middle tier cannot communicate properly, causing the login to fail silently. Option A would typically show a message. Option C would usually result in a specific ‘account locked’ error. Option D would likely cause a connection failure before the login page loads.

Question 10 of 10

10. Question
A developer on your team is building a new application module and needs to create a custom lookup type. They want this lookup to be available only within their specific application, not shared across the entire E-Business Suite installation. Considering maintenance and upgrade best practices, which approach should you recommend for defining this lookup?0
- Define a Data Group for the 'North America' OU and assign the report's executable to it.
- Use Function Security to exclude the report's submitting function from all responsibilities except the specific 'North America Manager' responsibility.
- Create a Request Group containing only this report, and attach that Request Group only to the 'North America Manager' responsibility.
- Write PL/SQL validation in the report itself to check the user's profile option value for 'ORG_ID' and fail if it doesn't match North America's ID.
Correct

The correct method is to use the standard Application Utilities Lookups form within the Application Developer responsibility. Setting the ‘Application’ field scopes the lookup to that specific product, making it portable and upgrade-safe. Direct database inserts (Option B) are unsupported and risky. Option C is irrelevant to lookups, and Option D violates the principle of using standard, maintainable frameworks.0
