How to Determine the Hostname In Oracle Apex?

In Oracle APEX, you can determine the hostname by utilizing the ORA_APEX_UTIL.GET_HOST_NAME function. This function returns the hostname of the server where your APEX application is running. You can use this function in a SQL query, PLSQL block, or an application process to retrieve the hostname dynamically. This can be useful for displaying the hostname in your APEX application or for any other functional requirements that involve the hostname.

from dual

1. Go to your application in Oracle APEX.
2. Edit the page where you want to display the hostname (typically the homepage).
3. Add a new region by clicking on the "Create" button in the appropriate region position (e.g., Page Body).
4. Choose "PL/SQL Dynamic Content" as the region type.

What is the impact of changing the hostname in Oracle APEX on existing applications?

Changing the hostname in Oracle APEX can have several impacts on existing applications:

1. URL changes: When you change the hostname, the URL of the application will also change. This may lead to broken links or bookmarks if users have saved the previous URL. It is important to communicate the new URL to all users to ensure access to the application.
2. Security considerations: Changing the hostname may impact the security of the application. Make sure that all security configurations and settings are updated to reflect the new hostname to ensure the security of the application is not compromised.
3. Integration issues: If the application is integrated with other systems or services, changing the hostname may affect the integration. Ensure that all integration points are updated with the new hostname to prevent any disruptions in the functionality of the application.
4. Performance impact: Changing the hostname may also have an impact on the performance of the application. Ensure that the new hostname is properly configured and optimized to ensure the smooth running of the application.

Overall, changing the hostname in Oracle APEX can have several impacts on existing applications, and it is important to carefully plan and execute the change to minimize any potential disruptions. It is recommended to test the changes in a development environment before implementing them in production to ensure a smooth transition.
