The proposed solution is correct. In IdentityIQ, the schema for core objects, such as Applications, is defined by an XML object called ObjectConfig. To add a new, persistent attribute to the Application object (i.e., extend the schema), the first and mandatory step is to modify the Application ObjectConfig to include the definition of this new attribute. Once this modified configuration is imported, the iiq schema command-line utility can be used to compare the new object model against the existing database schema and generate the required SQL DDL script (e.g., ALTER TABLE) to add the corresponding column.

B. No: This is incorrect. Modifying the ObjectConfig is the foundational and required step. Without this configuration change, IdentityIQ has no knowledge of the new attribute, and therefore no database script can be generated to accommodate it.

1. SailPoint IdentityIQ 8.3 Administration Guide, "Customizing the IdentityIQ Object Model" section: This guide details the process for extending core IdentityIQ objects. It states, "To add extended attributes to an IdentityIQ object, you must edit its ObjectConfig... After you have updated the ObjectConfig, you must update the database schema to reflect the changes." It then describes using the iiq schema command to generate the necessary DDL. (Reference points to the procedural necessity of modifying the ObjectConfig first).

2. SailPoint IdentityIQ 8.3 Installation Guide, "Creating IdentityIQ Database Tables" section: This document explains that the initial database is created from scripts, but for any customizations or upgrades, schema changes are required. It directs the user to the administration guide for customizing the object model and implicitly confirms that schema generation follows object model definition. The process of extending attributes is a customization that follows this principle.

3. SailPoint University, "IdentityIQ Administration" Courseware, Module on "System Configuration": The course materials explain that ObjectConfig objects define the data model for persistent objects in IdentityIQ. The labs and instructional content demonstrate that to add an extended attribute, one must first edit the ObjectConfig XML, import it, and then run a command to generate the database schema update script. This reinforces that the described solution is the correct initial action.
