A global page (usually numbered Page 0) functions as a master page in your application. The Application Express engine renders all components you add to a Global page on every page within your application. You can further control whether the Application Express engine renders a component or runs a computation, validation, or process by defining conditions. When you create a new application, Oracle APEX creates three default pages for the application. These are Page 1 (Home), Page 9999 (Login Page), and Page 0 (Global Page). You can also create the Global Page manually at a later development stage through the Create Page button and selecting Global Page as the page type. Note that the Global Page option appears on the Create a Page wizard screen only when the application does not already have a Global page.
In this tutorial, I’ll
use the Global Page to display two
buttons on every application page. The first button will allow users to
download the source of your application, while the second one will take them to the PayPal site to make
payments. The two buttons are highlighted in the following figure:
Here are the steps to see how things work through the Global Page:
1. Go to https://www.paypal.me/ and create a link to receive payments – mine looks like this https://www.paypal.me/techmining69.
2. Export your application file, compress it using WinZip or WinRar utilities, and upload it to your application’s file repository through the Static Application Files option in Shared Components.
3. Now, open the Global Page of your application, which is usually labeled as 0 - Global Page.
4. If the page is empty, add a breadcrumb region to it and set the following attributes for the region:

Save the Global Page and then run your application. The two buttons should appear on every application page, except for the login page. Click the buttons to test their respective actions.
