Recover Accidentally Deleted APEX Components Using Flashback Export

Deleting a page or shared component in Oracle APEX by mistake can be frustrating—but recovery is possible if you act quickly.

Why Flashback?

• Instead of relying on full database recovery (which is time-consuming and resource-intensive), APEX offers a Flashback Export option that utilizes Oracle’s Flashback Query technology via the Undo tablespace.

• How It Works:

  • Flashback Export is available for applications, pages, and components.

  • To recover a deleted page, create a dummy page with the same number, then export it using the Flashback Time setting.

  • Import the exported file—APEX will prompt to overwrite the dummy with the restored original.

• For Shared Components:
  If shared components were also deleted, export the entire application using the Flashback option and import it:

  • With the same App ID (overwrites the original app).

  • Or with a new App ID (lets you manually copy components from the flashback version).

• Best Practice:
  Schedule regular exports and store them in source control (e.g., Git), ensuring long-term recovery options—even for changes lost days or weeks ago.
