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.

How to display the hostname in Oracle APEX on the application's homepage?
To display the hostname in Oracle APEX on the application's homepage, you can create a dynamic text region and use the following PL/SQL code:
1 2 |
select utl_inaddr.get_host_name as hostname from dual |
- Go to your application in Oracle APEX.
- Edit the page where you want to display the hostname (typically the homepage).
- Add a new region by clicking on the "Create" button in the appropriate region position (e.g., Page Body).
- Choose "PL/SQL Dynamic Content" as the region type.
- In the Source section, enter the following SQL code:
1 2 |
select utl_inaddr.get_host_name as hostname from dual |
- Save the changes and run the page to see the hostname displayed on the homepage.
How to locate the hostname in Oracle APEX using PL/SQL code?
You can retrieve the hostname in Oracle APEX using the OWA_UTIL package in PL/SQL code. Here is an example code snippet to get the hostname:
1 2 3 4 5 6 |
DECLARE l_hostname VARCHAR2(255); BEGIN l_hostname := OWA_UTIL.get_cgi_env('SERVER_NAME'); DBMS_OUTPUT.put_line('Hostname: ' || l_hostname); END; |
This code will fetch the hostname of the server on which the Oracle APEX application is running and print it out using the DBMS_OUTPUT package.
Make sure you have the necessary permissions to execute PL/SQL code in your Oracle APEX environment.
How to retrieve the hostname in Oracle APEX using the APEX_UTIL package?
To retrieve the hostname in Oracle APEX using the APEX_UTIL package, you can use the following steps:
- Open your Oracle APEX application and navigate to the SQL Workshop.
- Create a new SQL Query.
- Use the following query to retrieve the hostname:
1 2 3 4 5 6 |
DECLARE l_hostname VARCHAR2(100); BEGIN l_hostname := APEX_UTIL.GET_HOST_NAME; DBMS_OUTPUT.PUT_LINE('Hostname: ' || l_hostname); END; |
- Execute the query.
This query will retrieve the hostname of the server where your Oracle APEX application is running and display it in the output.
How to extract the hostname in Oracle APEX from the server configuration settings?
To extract the hostname from the server configuration settings in Oracle APEX, you can use the following SQL query:
1 2 |
SELECT apex_instance_admin.get_host_name AS hostname FROM dual; |
This query uses the apex_instance_admin.get_host_name function to retrieve the hostname from the server configuration settings in Oracle APEX. You can run this query in SQL Workshop or SQL Commands in Oracle APEX to extract the hostname.
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:
- 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.
- 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.
- 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.
- 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.
