6.3.2 About Configuring Oracle REST Data Services Behind a Reverse Proxy or Load Balancer
When Oracle APEX is running behind a reverse proxy or load balancer, it is important to communicate the original HTTP hostname and protocol as seen by the user's browser to the Oracle APEX engine.
The Oracle APEX engine uses this information to generate valid URLs in HTML responses and HTTP redirects that the user's browser can successfully follow. The exact configuration steps depend on your Java EE application server. For example, for Oracle WebLogic Server, this is accomplished using Oracle WebLogic Server Proxy Plug-Ins. To learn more, see your Java EE application server documentation.

6.3.3 Web Server HTTP POST Request Limits
Learn about Web Server HTTP POST request limits.
When running Oracle REST Data Services (ORDS) in standalone mode or within a Tomcat Java Container, size limits are being imposed on POST requests which are not file uploads. Oracle APEX users will encounter these limits when uploading data in SQL Workshop using copy and paste or when using copy and paste while building an application from spreadsheet.
-
When running Oracle REST Data Services in Standalone Mode, the default limit is 200 KB for ORDS 19.4.6 and earlier. It is recommended to increase the limit as follows:
Set the Java System property
org.eclipse.jetty.server.Request.maxFormContentSize
to a higher value in bytes. You can set this property upon startup of Oracle REST Data Services. For example:java -Dorg.eclipse.jetty.server.Request.maxFormContentSize=3000000 -jar ords.war
-
When running on Apache Tomcat, the default limit is 2 megabytes. Adjust Apache Tomcat's
maxPostSize
parameter to change that limit.See Also:
http://tomcat.apache.org/ for more information.
