Recently I had to set up an Oracle Apex Server. Unfortunately the Apex Installer is delivered only as Windows 32 Bit installer and as a Linux 64 Bit RPM package.
Since I did not have any 32 Bit windows running, and neither any Linux system, that normally uses RPM packages, I decided to give Oracle Linux a try as base for an Oracle APEX Server.
What is Apex?
APEX is a rapid application development tool from Oracle. It lets you design, implement and deploy database applications with a very easy to use web gui. For common task like showing reports or creating forms for data entry you can use one of the many prepared templates. With APEX you could create an entire application around your database with little to no knowledge of any programming or scripting language.
If you need more specialised pages, then the default templates offer to you , you can build a page from scratch with any combination of predefined elements, custom PL/SQL code and custom javascript / HTML code.
