Application Express Servers

The servers in apex are

!) APEX listeneer
2) http server

3) embedded plsql



Till 11.1 db there was the three tier architecture , hence the apex listener and http port had to be sperately installed.

Then in 11. or later or in XE , comes with embedded plsql

A two tier architecture .

hence no need to install the servers manually.
