Our current APEX configuration uses Oracle OHS with mod_plsql on Linux. In this situation, it is clear that the browser connects to OHS, makes a HTTP request and OHS hands that request to the APEX engine in the Oracle Database via mod_plsql which satisfies the request and returns a response back to OHS and back to the browser.
When using ORDS in standalone mode, the browser connects to ORDS which uses JDBC to connect to the APEX engine in the Oracle Database which satisfies the request and returns a response back to ORDS and back to the browser.
Questions:
1. When ORDS is deployed in a Apache Tomcat container, I am not sure I understand how the data flows. Who acts as the web server in this case, ORDS or the Coyote HTTP connector inside Tomcat? What component connects to the APEX engine?
2. When Apache and Kerberos are thrown into the mix as shown in Single Sign-On for APEX applications using Kerberos same questions, what component does what exactly?
Thanks
