In Oracle Integration (OIC), the standard and recommended method for using reusable custom JavaScript code is to package it as a library file (.js). This file is then imported as a resource into the OIC project. Within the integration canvas, the "JavaScript" action is used to execute code. This action can be configured to invoke specific functions defined within the imported library, promoting code reusability and maintainability across different integrations within the same project.

A. OIC is a PaaS offering; developers do not directly import files into its database schema. The "Local Invoke" action is for calling other OIC integrations, not JavaScript functions.

C. While you can write code directly in the JavaScript action, this defeats the purpose of a reusable library. The best practice for libraries is to import the file, not copy-paste code repeatedly.

D. The "Function Call" action is specifically designed to invoke serverless functions deployed on the Oracle Functions platform, not to execute JavaScript from an arbitrary external URL.

1. Oracle Official Documentation - Using Integrations in Oracle Integration 3:

Section: Call JavaScript Code in an Integration

Content: The documentation explicitly outlines the process: "You can create a JavaScript library with functions that you want to call from multiple integrations. You then register the library with Oracle Integration and call the functions from a JavaScript action in your integrations." It details the steps to add a JavaScript library to a project and then call its functions.

2. Oracle Official Documentation - Using Integrations in Oracle Integration 3:

Section: Add a JavaScript Action

Content: This section describes the configuration of the JavaScript action itself. It shows how to either write inline code or

more relevantly

call a function from a registered library. This confirms that the "JavaScript" action is the correct component to use.

3. Oracle Official Documentation - Using Integrations in Oracle Integration 3:

Section: Add a Function Call Action

Content: This documentation clarifies that the "Function Call" action is used to "configure a call to an Oracle Functions application." This directly refutes option D by specifying the action's true purpose.
