22.214.171.124 Exporting an Application Page
Move or copy a single application page by exporting it.
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.
To export a page in an application:
- View the page in Page Designer:
Page Designer appears.
- On the Workspace home page, click the App Builder icon.
- Select an application.
- Select a page.
- In Page Designer, select Export.
- On the Page Developer toolbar, click the
- Select Export.
The Export Page Wizard appears.
- On the Page Developer toolbar, click the Utilities menu.
- On Export Page:
- Page - Select the page you wish to export. You can select only one page for export at a time.
- Export as Zip - Options include:
On - Export as a ZIP archive containing a separate SQL files for the page.
Off - Export as a single SQL file.
- Include Installation files - Only displays if
Export as Zip is set to
On. Options include:
On - Generates a ZIP archive including installation files specifically for the Page Export.
Off - Generate a ZIP file without the installation files.
Oracle recommends Off when saving the files to a version control system so that application installation files are not overwritten.
To learn more about the Zip archive, see Splitting Export Files into Separate Scripts.
- 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_FLASHBACKpackage. 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_RETENTIONparameter, 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.
- File Character Set - Indicates the character set in which the export file will be encoded. When importing this file you will need to specify the same character set.
- Click Export Page.
- Import the Page Export into the target instance.
