Which four statements are true about the Optimize Dimension feature?

In Oracle Planning 2024, the Optimize Dimension feature enhances performance by reordering dimensions in BSO (Block Storage Option) cubes. Let’s evaluate the six statements to determine the four that are true:

A. The new optimized dimension order is maintained even if you enable additional features or other modules: True. Once optimized, the dimension order remains intact even if new features or modules are enabled, unless explicitly re-optimized or manually altered. This ensures performance stability post-optimization.

B. You can optimize the dimension order only for BSO cubes in Custom Planning applications: True. The Optimize Dimension feature is exclusively available for BSO cubes in Custom Planning applications, not for ASO (Aggregate Storage Option) cubes or module-based applications (e.g., Financials, Workforce), due to their predefined structures.

C. You can optimize the dimension order only for Financials and Projects, and only for the provided BSO cubes that are created when you enable and configure: False. This statement is incorrect because the feature applies to Custom Planning applications, not specifically to Financials and Projects, which use predefined BSO cubes not eligible for user-driven dimension optimization.

D. You optimize dimension order first in your test environment before you optimize dimension order in the production environment: True. Oracle recommends testing dimension optimization in a test environment first as a best practice to assess performance impacts and avoid risks in production, making this a procedural truth.

E. You refresh the database and then back up the application and download the snapshot before you optimize dimension order: True. Before optimizing, Oracle advises refreshing the database to ensure data consistency, then backing up the application and downloading a snapshot to preserve a recovery point in case optimization causes issues.

F. You can optimize the dimension order only for Financials and Workforce, and only for the provided BSO cubes that are created when you enable and configure: False. Similar to C, this is incorrect; optimization is not restricted to Financials and Workforce module cubes—it’s for Custom Planning BSO cubes, not predefined module-specific cubes.

From these, the four true statements are:

A – Persistence of the optimized order after feature/module changes.

B – Restriction to BSO cubes in Custom Planning applications.

D – Testing in a test environment first as a best practice.

E – Refreshing and backing up before optimization.

The false statements (C and F) incorrectly limit the feature to specific modules (Financials, Projects, Workforce), whereas it’s designed for Custom Planning applications. The Oracle documentation supports A, B, D, and E as true, aligning with the feature’s functionality and recommended practices.
