25.3.2.5 Exporting an Application Page

Move or copy a single application page by exporting it. You can export or page from the Export page or from Page Designer.

WARNING:

Exporting and importing a single page to a different system is an advanced deployment technique with the following restrictions:

  • Both systems have to have the same application ID and workspace ID.
  • Both systems have to have the same IDs for Shared Components.
  • If the page references new or updated Shared Components, those have to be exported and imported first.

If these restrictions are not fulfilled, the import will fail.

25.3.2.5.1 Exporting an Application Page from the Export Page

Move or copy a single application page by exporting it from the Export Page.

To export a page from the Export page:

  1. Navigate to the Export page:
    1. On the Workspace home page, click the App Builder icon.
    2. On the App Builder home page, click Workspace Utilities.
    3. Click Export.

      The Export page appears.

      Tip:

      You can also access the Export page by selecting the application, Export/Import, and then Export.
  2. Click the Page tab.
  3. On the Export Page, configure the following:
    1. Application - Select the application that contains the page to be exported.
    2. Page - Select the page you wish to export. You can select only one page for export at a time.
    3. Include Installable SQL File - Specify whether the export file should include the installable SQL file for the page. Options include:

      • On - Includes the installable SQL file.

      • Off - Excludes the installable SQL file.

    4. Include Readable Format - Specify whether the export file should include the human-readable (YAML) version of the page meta-data. Use the YAML version to identify and review differences between versions of a page when checked into a Version Control System. Options include:
      • On - Include the human-readable file.
      • Off - Exclude the human-readable file.
    5. Split into Multiple File - Select this option to export separate SQL files for the page, shared components, and so on. Options include:
    6. Original IDs - Specify whether the export file should contain the application component IDs as of now or as of the last import of this application. Options include:

      • On - Include the IDs as of the last import.

      • Off - Include the current IDs of the components.

    7. Audit Information - Specify the audit information to include in the export file. Audit information includes the Created By User, Created On Date, Changed By User and Changed On Date. Options include:
      • None - (Default) No audit information is included.
      • Names and Dates - Include names and dates in all audit information.
      • Dates Only - Only include date information and exclude user details.
    8. As of - Specify a time in minutes to go to back to for your export. This option enables you to go back in time in your application, perhaps to get back a deleted object.

      This utility uses the DBMS_FLASHBACK package. Because the timestamps to System Change Number (SCN) mapping is refreshed approximately every five minutes, you may have to wait that amount of time to locate the version for which you are looking. The time undo information is retained and influenced by the start up parameter UNDO_RETENTION (the default is three hours). However, this only influences the size of the undo table space. While two databases may have the same UNDO_RETENTION parameter, you are able to go back further in time on a database with fewer transactions because it is not filling the undo table space, forcing older data to be archived.

    9. File Character Set - Identifies the character set in which the export file will be encoded.
  4. Click Export .
  5. Import the Page Export into the target instance.
