The Oracle Application Express (APEX) Listener Administration window enables you to specify global settings and database settings for the APEX Listener, a web server that proxies requests between a web browser and the Oracle Application Express engine. The APEX Listener simplifies the deployment process because there is no Oracle home required as connectivity is provided using an embedded JDBC driver.
This topic does not explain the major APEX Listener concepts or the details of specific settings. For these, see Oracle Application Express Listener Installation and Developer Guide, especially the chapter on configuring Oracle APEX Listener and the chapter on RESTful APIs and resource templates.
The APEX Listener Administration window has icons at the top for performing the following actions:
New Administration displays the Create Listener Administration dialog box, where you specify the Name and optionally a Description of the administration.
