Overview
Oracle Application Express (APEX) is a low-code development platform that enables you to build scalable, secure enterprise apps, with
world-class features, that can be deployed anywhere.
Client Browser
Mobile Device
Browser-Based Development Platform

Architecture
Oracle APEX uses a simple 3-tier architecture where requests are
sent from the browser, through a web server, to the database.
All processing, data manipulation and business logic is executed
in the database.
Oracle APEX uses a database encapsulated simple metadata-
driven architecture that guarantees zero latency data access, top
performance, and scalability, out of the box.
The web server, Oracle REST Data Services (ORDS) (formerly
known as Oracle Application Express Listener) is a J2EE
application which communicates with the Oracle Database by
mapping browser requests to the Oracle APEX engine database
over a SQL*Net connection.
Oracle REST Data Services is fully supported against Oracle
WebLogic Server and Apache Tomcat.

The Oracle RAD Stack
The Oracle RAD stack is an inclusive technology stack based on three core
components:
• REST Data Services (ORDS)
• APEX
• Database
This stack provides all the necessary components to develop and deploy
world-class, powerful, beautiful, and scalable apps.
There are no other moving parts of additional components required.
In addition, both Oracle APEX and ORDS are no-cost features of Oracle Database, meaning if you have Oracle Database, you already
have this Oracle RAD stack.

Understanding Oracle APEX Installation
When installing Oracle Application Express there are a number of key architecture and management areas to understand.
1. Database
2. Web Listener
3. Multi-Tenancy
4. Environments
5. Roles and Responsibilities

• Database
The installation of Application Express creates a separate schema (APEX_230100 for APEX 23.1) to house the programs that make
up the Application Express engine and related metadata tables.
Following the install guide, at a certain moment, we have to run the following command, when logged in as SYS with the SYSDBA
role, on the command line:
@apexins tablespace_apex tablespace_files tablespace_temp images
The command is explained as follows:
− tablespace_apex is the name of the tablespace that contains all the objects for the APEX application user.
− tablespace_files is the name of the tablespace that contains all the objects for the APEX files user.
− tablespace_temp is the name of the temporary tablespace of the database.
− images is the virtual directory for APEX images. To support future APEX upgrades, define the virtual image directory
as /i/.
Oracle recommends you create tablespaces specifically for the Application Express engine and Application Express files to enable
better management and monitoring.
For example, Tablespace APEX_TS_230100 would contain the Application Express engine and APEX_TS_FILES for the Application
Express files, but the names are arbitrary.
Your initial installation step, as outlined in the Oracle Application Express Installation Guide, Downloading from Oracle Technology
Network, would then be
@apexins.sql APEX_TS_230100 APEX_TS_FILES TEMP /i/.

As a best practice, install Oracle Application Express into the database(s)
which have the database objects you wish to use in your applications.
You can also utilize Oracle database links and integrate your
applications with Web Services.
The multitenant option represents one of the biggest architectural
changes in the history of the Oracle database.
The option introduced the concepts of the Container Database (CDB)
and Pluggable Database (PDB).
In Multitenant architecture, Oracle has a great option to act as a System as a Service (SaaS), and create different databases for
specific applications such as sales database, hr database.
So installing apex in different PDB is good to maintain and you can install apex in different PDB databases.
This database architecture has a multitenant container database (CDB)
that includes:
1. A root container, CDB$ROOT, holds common objects that are
accessible to every PDB utilizing metadata links or object links.
2. A seed database, PDB$SEED, is used when creating a new PDB to
seed the new database.
3. And multiple pluggable databases (PDBs). Each pluggable
database is equivalent to a separate database instance in Oracle
Database release 11g.
The key benefit of the Oracle Database 12c or later multitenant architecture is that the database resources, such as CPU and
memory, can be shared across all of the PDBs.
This architecture also enables many databases to be treated as one for tasks such as upgrades or patches, and backups.

• Web Listener
Oracle Application Express uses a simple architecture where pages are dynamically generated using metadata stored within the
Oracle Database.
There is no code generation or file based compilation. Once fully installed, a Uniform Resource Locator (URL) is defined for both
developers and end users to access Oracle Application Express.
Users require only a Web browser and the required URL. No additional client software is required.
The Web listener functions as a communications broker between the Web browser and the Oracle Application Express objects in
the Oracle database by mapping browser requests into database stored procedure calls.
You have a choice of three Web listeners.
− Oracle REST Data Services (preferred option - formerly Oracle Application Express Listener).
− Oracle HTTP Server.
− Embedded PL/SQL gateway.
Using Oracle REST Data Services creates an architecture which consists of:
− A web browser
− Oracle REST Data Services
− Oracle Database containing Oracle Application Express
The major advantage of this architecture is the separation of the mid-tier and the database tier.

• Multi-Tenancy
Oracle Application Express enables a single database to
host large numbers of applications and users.
Developers work in a dedicated work area called a workspace to develop
applications against one or more schemas.
This flexible architecture enables a single database instance to act as a
Platform as a Service (PaaS), providing a hosted Intranet capability within
the organization, or hosted Internet service.
It is common for workspaces to be defined for separate departments
within an organization so that each department can develop their own
database objects and applications independently.

• Environments
When you install Oracle APEX, you can install two different environments:
− Runtime environment (Run apxrtins.sql). In a runtime environment users can run applications but cannot modify them.
Select this option for production implementations.
− Full development environment (Run apexins.sql). In a full development environment, users can develop, modify, run, and
delete APEX applications. This option provides complete access to the APEX environment.
Converting runtime into a full development environment and vice versa
It's always possible to switch from a runtime to a production environment and vice versa.
− If you want to convert a runtime to a full development environment log in as SYS with the SYSDBA role and on the
command line type @apxdvins.sql. For converting a full development to a runtime environment, type
@apxdevrm.sql. For more details see the installation guide.
− Another way to restrict user access can be accomplished by logging in to the APEX Administration Services, where we
can (among others) manage the APEX instance settings and all the workspaces.
We can do that in two ways:
http://server:port/ords/apex_admin: Log in with the administrator credentials
http://server:port/ords/: Log in to the workspace internal, with the administrator credentials. After logging in,
perform the following steps:
1. Go to Manage Instance → Select Security.
2. Select the appropriate settings for Disable Administrator Login and Disable Workspace Login. These settings can
also be set manually with the APEX_INSTANCE_ADMIN API. See the reference guide for details.
− Besides the environment of APEX itself, the applications can also be installed in a similar way. When importing or
exporting an application the Run Application Only or Run and Build Application options can be selected.
Build Status - Set the build status of the application. Options include:
1. Run Application Only - Users can only run an application. This option is an effective way to protect an application
from modifications from other developers.
2. Run and Build Application - Developers and users can both run and develop the application.

• Roles and Responsibilities
Users are divided into four primary roles:
1. Instance administrators are superusers that manage an entire hosted instance using a separate application
called APEX Administration Services. Instance administrators manage workspace provisioning, configure features and instance
settings, and manage security.
2. Workspace administrators can perform administrator tasks specific to a workspace such as configuring workspace
preferences, managing user accounts, monitoring workspace activity, and viewing log files.
3. Developers are users who sign in to a workspace and create and edit applications.
4. End users can only run existing applications.

Oracle APEX Installation Requirements
Before installing Oracle APEX in a local self-managed installation you must verify your configuration meets the minimum installation
requirements.
• Oracle Database Requirements
Oracle APEX release 23.1 requires an Oracle Database release 19c or later.
• Browser Requirements
Oracle APEX requires a JavaScript-enabled browser and supports the current and prior major release of Google Chrome,
Mozilla Firefox, Apple Safari, and Microsoft Edge.
• Web Server Requirements
Oracle APEX requires Oracle REST Data Services (ORDS) 20.x or later. ORDS can be deployed on WebLogic, Tomcat or run in
standalone mode. This article describes the installation of ORDS on Tomcat 9.

the database where APEX will be installed as
SYS specifying the SYSDBA role.
command:
sqlplus sys/sys as sysdba
command: show pdbs;
command:
alter session set container =
apex_pdb_23;

command: show con_name;
command:
select * from v$tablespace;
command:
CREATE TABLESPACE APEX
DATAFILE
'C:APEX_DEVDATABASEoradataPDB
SAPEX_PDB_23apex01.dbf'
SIZE 100M AUTOEXTEND ON NEXT 1M;

Take a quick look on the database files.
command:
select * from v$tablespace;
Automate Pluggable DB opening during
Container instance startup
command:
alter session
set container = cdb$root;

command:
ALTER PLUGGABLE DATABASE apex_pdb_23
SAVE STATE;
command: show pdbs;
command: exit;

To install Oracle Application Express:
Unzip downloaded zip file
(apex_23.1.zip), folder path
(C:APEX_DEVINS_FILESapex).
Start Windows PowerShell
Change your working directory to apex.
command:
cd C:APEX_DEVINS_FILESapexapex
Start SQL*Plus and connect to the
database where APEX will be installed as SYS
specifying the SYSDBA role.
command:

Select PDB Database
command:
APEX_PDB_23;
Run the apexins.sql script, specifying the
relevant tablespace names and image URL.
See more here.
command:
@apexins.sql APEX APEX TEMP /i/
It will create many files and finally shows the
message as shown.

Run the apxchpwd.sql script to create or
update your Instance Administrator account.
Follow the on-screen instructions.
You will be prompted provide a username,
password, and email address. If the account
username does not exist, it will be created
for you. See more here.
command: @apxchpwd.sql
Configuring Static File Support.
When using Oracle REST Data Services as
your web listener, static files are served using
RESTful service module built into Oracle
Application Express. See more here.
Therefore, you must run
apex_rest_config.sql after a new
installation or upgrade of Oracle Application
Express.
This will ask you to give APEX_LISTENER
and APEX_PUBLIC_USER password to set
which will be used later for the ORDS setup.
command: @apex_rest_config.sql

Configuring the accounts of APEX / ORDS
services.
command:
APEX_PDB_23;
command:
ALTER user APEX_230100 IDENTIFIED
BY Apex_123 account unlock;

command:
ALTER user APEX_PUBLIC_USER
IDENTIFIED BY Apex_123 account
unlock;
command:
ALTER user APEX_LISTENER
unlock;
command:
ALTER user APEX_REST_PUBLIC_USER
unlock;

Unlock the ANONYMOUS account.
command:
ALTER user ANONYMOUS IDENTIFIED
BY Apex_123 account unlock;

Installing Oracle REST Data Services (ORDS):
Unzip the downloaded zip (ords-
latest.zip) file into a directory
(C:APEX_DEVINS_FILESords).
Setting Up the Configuration Folder
Structure:
− New installation has the ORDS
configuration files placed in the
configuration folder.
− The best practice is to have your
configuration files separate from the
application files, Create the configuration
directory (config) in the ORDS folder
(C:APEX_DEVINS_FILESordsco
nfig)

Setting Environment Variables:
Adding ORDS bin folder to your Operating
System PATH:
The ORDS product folder contains
a bin folder and other folders and files
required to run ORDS.
Oracle recommends to add the
ORDS bin folder to your operating system
PATH environment variable.
Use a command with administrator
privileges.
command:
SetX PATH "%PATH%;
C:APEX_DEVINS_FILESordsbin"

Setting Up the Configuration Folder location:
command:
SetX ORDS_CONFIG
"C:APEX_DEVINS_FILESordsconfi
g" /m
command:
SetX _JAVA_OPTIONS "-
Dconfig.url=C:APEX_DEVINS_FILES
ordsconfig" /m
command:
SetX JAVA_TOOL_OPTIONS "-
Dconfig.url=C:APEX_DEVINS_FILES
ordsconfig" /m

Set JAVA_HOME
command:
SetX JAVA_HOME " C:Program
FilesJavajdk-11" /m

Copying the Images Directory:
Whether you are loading a new installation
or upgrading from a previous release, you
must copy the images directory from the top
level of the apeximages directory to the
Tomcat "webappsi" directory.
command:
mkdir "C:Program FilesApache
Software FoundationTomcat
9.0webappsi"
command:
xcopy /s /e /i
C:APEX_DEVINS_FILESapexapexi
mages "C:Program FilesApache
9.0webappsi"
Copy the "ords.war" file to the Tomcat
"webapps" directory.
command:
copy
C:APEX_DEVINS_FILESordsords.w
ar "C:Program FilesApache
9.0webapps"

ORDS Interactive Command-Line Interface
Installation:
command:
CD C:APEX_DEVINS_FILESords
Execute the following setup command with -
-config option to specify your
configuration folder to create the
configuration files:
