Installation of Oracle APEX(Application Express ) in OEL 6

This document describes how to install Oracle Application Express(APEX) in OEL 6.

What is APEX?

Oracle Application Express (Oracle APEX), is the low code web application development tool for the Oracle database. Application Express enables you to design, develop and deploy beautiful, responsive, database-driven applications, either on-premises or in the cloud.

Using only a web browser and limited programming experience, you can rapidly develop and deploy professional applications that are both fast and secure for any device from desktop to mobile. Oracle Application Express combines the qualities of a low code tool such as productivity, ease of use, and flexibility, with the qualities of an enterprise development tool such as security, integrity, scalability, availability and built for the web.

We can install APEX in two different ways.
1. Full development environment
2. Run time environment

Full development environment: A full development environment provides complete access to the Application Builder environment to develop applications.

Run time environment: A run time environment is an appropriate choice for production implementations in which you want to run applications that cannot be modified.

Reference: https://www.oracle.com/technetwork/testcontent/what-is-apex-099128.html

Installation of Oracle APEX:

1. Assumptions
2. Download Software
3. Prerequisites
4. Installation

1. Assumptions:

We assume that already installed Oracle Database 12.1.0.2 in Oracle Enterprise Linux 6.
Please click here to know how to install 12c database if did not install it before.

2. Download Software:

Click here to download Apex 5.0.3 software.

3. Prerequisites:

1. Free space for Oracle Application Express software files on the file system: 625 MB
2. Free space in SYSTEM tablespace: 100 MB

Oracle XML DB must be installed in the Oracle database which we are using to install APEX. If your database is installed with DBCA the XMLDB installed along with database installation.

If you have done the database installation manually we need to create XML DB manually. To create the XML DB we have to run the below script.

$cd $ORACLE_HOME/rdbms/admin

SQL>@catqm.sql

4. Installation:

Step 1:

Create one tablespace which we can make it as default tablespace while installing APEX.

SQL> create tablespace APEX_DATA datafile '/u02/oradata/SILVER/apex_data01.dbf' size 10m autoextend on maxsize unlimited;

Tablespace created.

SQL>

Step 2:

Change to the directory where downloaded the software and run below script to install APEX.

[oracle@server2 ~]$ cd /u02/softwares/apex

[oracle@server2 apex]$ pwd
/u02/softwares/apex

Connect as sysdba to install APEX.

[oracle@server2 apex]$ sqlplus / as sysdba
