Oracle Application Express (Oracle APEX) is Oracle’s primary tool for developing Web applications with SQL and PL/SQL. Using only a web browser, you can develop and deploy professional Web-based applications for desktops and mobile devices. It is a fully supported, no cost option of the Oracle Database, and is installed by default in all editions of the Oracle Database.
We will deploy the latest version of APEX (v.4.2.5 at the time of writing this tutorial) in a patched database 12c.
EDIT: This installation guide also applies to APEX version 5.
Oracle Application Express is unique amongst Oracle Database 12c options in that it can be uninstalled from the root container, CDB$ROOT, unlike other options. This capability allows you to re-install “runtime only” Application Express into the root container. Alternatively, once Application Express is removed from the root container you can manually install different versions of Application Express, Release 4.2.0 or above, into each PDB. In this tutorial we will install APEX into the pluggable database PDB01. Alternative installation options have been explained in this white paper.
Post-installation of Oracle Database 12c Multitenant you can log into the root container and run apxremov_con.sql. This will remove Application Express from the root container, the PDB Seed and all PDBs within the CDB. It is very important to understand that this will also remove all of the Application Express meta-data (application definitions) stored within all of the PDBs. Therefore, Oracle strongly recommends that this script only be run when initially configuring the CDB, and before starting any Application Express development, to ensure applications are not inadvertently deleted.
