Introduction:
Beginning with Oracle APEX 20.2, the only supported Web listener is Oracle REST Data Services (ORDS).
What is ORDS?
- Oracle REST Data Services (ORDS) is a data service which is used to replace Oracle HTTP server and mod_plsql
- It is based on Java EE that provides RESTful service and increases security capability
- It can be deployed on WebLogic, Tomcat, Glassfish or independently
Deprecation of the embedded PL/SQL Gateway and mod_plsql:
- The deprecation of the embedded PL/SQL Gateway and mod_plsql was announced in APEX 20.1
- And beginning from APEX 20.2, these Web listeners are no longer supported, with the only supported Web listener being Oracle REST Data Services (ORDS)
- ORDS has long been the strategic direction of APEX, and it provides far more functionality than the other web listeners
- ORDS is what Oracle uses for all deployments of APEX – apex.oracle.com, APEX on Oracle Cloud, Oracle Store, and more
License information for ORDS:
- The license for ORDS is just like the license for APEX – if you’re licensed and supported for Oracle Database (including XE), then you’re also licensed and supported for APEX and ORDS
- If you’re used to running APEX on XE using the database’s embedded Web server (i.e., embedded PL/SQL Gateway), then you’ll probably want to use the simple, standalone version of ORDS
