This Document provides an overview of installing of Oracle Application Express on Different Oracle

Database (10g, 11g, XE) and How to Choosing an HTTP Server.

If you the first time using Oracle Application Express we must know that Oracle application Express

(ORACLE APEX) is the native Web application development framework for the Oracle Database.

Using only a web browser and limited programming experience.

Where oracle apex builds a web application there should be a web server between web browser and

Database to handle request between both of them so before running oracle apex we must have access

one of 3 options provided by oracle.

Before running Oracle Application Express you must have access one of the following:

Oracle Application Express Listener

Oracle HTTP Server and mod_plsql

Embedded PL/SQL gateway

To know the Oracle APEX Architecture and what happen when running APEX show the following

Figure:

Figure 1. The Oracle HTTP Server architecture

In this case (use oracle HTTP Server) the web server sits between the web browser and the

Database and is responsible for handling the requests from the web browser, passing them

through to the database (via something called mod_plsql), then APEX processes the request and

generates the response (the HTML code to send back) which is passed by to the browser via the

mod_plsql module in the OHS. The version prior Oracle Database 11.1 required Oracle Application Express Listener OR Oracle HTTP Server (Apache) with mod_plsql

Figure 2. Using the Embedded PL/SQL Gateway

Oracle XML DB HTTP Server with the embedded PL/SQL gateway installs with Oracle Database 11g. It

provides the Oracle database with a Web server and also the necessary infrastructure to create dynamic

applications. The embedded PL/SQL gateway runs in the Oracle XML DB HTTP server in the Oracle

database and includes the core features of mod_plsql.

As shown in the figure, the embedded PL/SQL gateway consists of simple two tier architecture: a Web

browser and an Oracle database containing the embedded PL/SQL gateway and Oracle Application

Express.

Advantages of the embedded PL/SQL gateway include:

Ease of configuration

Included in the database

No separate server installation

Embedded PL/SQL Gateway

Embedded PL/SQL

.


Available Installation Scenarios for APEX

After we know the Oracle APEX Architecture the installation of Oracle APEX depends upon HTTP server you decided to use .there 3 scenarios to install Oracle APEX

Scenario 1: Downloading from OTN and Configuring the Oracle Application Express Listener

Scenario 2: Downloading from OTN and Configuring the Embedded PL/SQL Gateway

Scenario 3: Downloading from OTN and Configuring Oracle HTTP Server

1-Install oracle APEX and configuring the oracle Application Express Listener

Download and installation Oracle APEX

1. Download apex_4.1_EN zip file from oracle apex download page..see below link http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html

2. Unzip download file , preserving directory names

3. Change you working directory to apex


4. I prefer to create new Tablespace for APEX installation for holding APEX objects and any files uploaded to the database .To create new table space called APEX run the following : CREATE TABLESPACE APEX datafile path/APEX.dbf

SIZE 300M

EXTENT MANAGEMENT LOCAL

SEGMENT SPACE MANAGEMENT AUTO;

(Skip this step if you dont want create new Tablespace)

5. Start SQL*Plus and connect to database as sys users and Run apexins.sql

@apexins tablespace_apex tablespace_files tablespace_temp images

tablespace_apex: name of the tablespace for the Oracle Application Express application user. tablespace_files: name of the tablespace for the Oracle Application Express application files user. tablespace_temp: name of the temporary tablespace.

Images: image directory for oracle Application Express and define as /i/ Example: You must in the APEX Directory to run this command

@apexins APEX APEX TEMP /i/ (if you create new Tablesapce)

OR

@apexins SYSAUX SYSAUX TEMP /i/ (if you dont create Tablesapce)

Wait until installation finish (approximately 30-40 min) =====================================================================

Note: there are 2 APEX installation options Full development environment :provide complete access to the application builder environment

to develop application RUN @apexins

Runtime environment :enable user to run application without modified it RUN @apxrtins


When Oracle Application Express installs, it creates three new database accounts

APEX_040100 - The account that owns the Oracle Application Express schema and metadata.

APEX_PUBLIC_USER - The minimally privileged account is used for Oracle Application Express configuration with Oracle Application Express Listener or Oracle HTTP Server and mod_plsql.

FLOWS_FILES - The account that owns the Oracle Application Express uploaded files.

6. Change the password of Admin account of Oracle Application Express follow this steps

Change your working directory to the apex directory where you unzipped the installation software

Connect to database as sys where oracle APEX is installed and Run apxchpwd.sql

We will use this account to login in to APEX Admin Console


7. Unlocking the APEX_PUBLIC_USER Account where this account locked at the end of new

installation of oracle apex so we must unlock this account before configuring the database access descriptor (DAD).

Connect as sys and run the following script ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK

Change password of APEX_PUBLIC_USER

ALTER USER APEX_PUBLIC_USER IDENTIFIED BY new_password

Download and Configure Oracle Application Express Listener

8. Download the latest version from oracle Application Express Listener

http://www.oracle.com/technetwork/developer-tools/apex-listener/downloads/index.html

9. Unzip APEX Listener file , preserving directory names


Oracle Apex Listener can be used in combination with any of 3 following webserver or

Can be used in standalone mode:

Oracle WebLogic Server

Oracle Glassfish Server.

Oracle Containers for J2EE (OC4J). In this Document Iwill discuss install and run Oracle APEX Listener in Standalone mode

10. After Unzip the Listener folder run the following command after get into ( Oracle Application Express Listener Required Java 6 Update 20 JDK or higher):

java jar \apex.war

temp directory : is the directory location of the unzipped Oracle Application Express Listener.

When prompted, enter path of the location of the APEX folder which containing the static resources used by Oracle Application Express (ex: C:\APEX\images)

When prompted, choose a user name and password for the Oracle Application Express Listener

Administrator and Manager roles.


Adjust the configuration of your server and press Apply

To access Listener configuration: http://:/apex/listenerConfigure

Ex: localhopst: 8080/apex/listenerConfigure

Congratulations Oracle Application Express install successfully

=================================================================================

VIP Note: there are folder in unzip APEX folder called images this file contain all apex required resources (css,

image..etc) And must be specify the path of this file when start Oracle Application Express Listener

=================================================================================


Oracle Application Express listener connection

Access Oracle Application Listener Administration: http://:/apex/listenerConfigure, http://:/apex/listenerAdmin

Oracle Application Express Listener Status : http://:/apex/listenerStatus

To start Listener run following command:

\\java Dapex.images= -jar apex.war .

To display a full list of available commands, execute the following command:

java jar apex.war --help

To stop the Oracle Application Express Listener server in standalone mode, at a command prompt press

CTRL+C.

Apex connection

Access Apex Admin Console: : http://:/apex/apex_admin

Access apex workspace console: http://:/apex


2-Install oracle APEX and configuring the Embedded PL/SQL Gateway (EPG)

The Embedded PL/SQL Gateway install with the Database11g but must be Configure it before use it with Oracle Application Express.

1- Download and Install Oracle Apex ( see steps 1-7 in APEX Installation)

2- Running the apex_epg_config.sql Configuration Script to configure embedded PL/SQL ( script

found in Unzip APEX folder)

Change your working directory to the apex directory where you unzipped the Oracle Application Express software.

Start SQL plus and connect as sys user and Run the apex_epg_config.sql passing the path where oracle APEX Software Unzipped :@apex_epg_config c:\apex

3- Unlock ANONYMOUS, APEX_PUBLIC_USER account : ALTER USERS ANANYMOUS ACCOUNT UNLOCK;

ALTER USERS APEX_PUBLIC_USER ACCOUNT UNLOCK;

4- Load the APEX Images by run following script:

Start SQL plus and connect as sys user passing the path where oracle APEX Software Unzipped : @apexldimg c:\apex

5- Verifying the Oracle XML DB HTTP SERVER PORT where EPG runs in this server by default this server disabled and must be enabled

To check the status to Oracle XML DB HTTP Server runs the command

SELECT DBMS_XDB.GETHTTPPORT FROM DUAL;


If the port number return 0, the Oracle XML DB HTTP Server is disabled and Enabled by run

following command:

EXEC DBMS_XDB.SETHTTPPORT(port)

For example:

EXEC DBMS_XDB.SETHTTPPORT(8080)

Now you can access the APEX page as

http://:8080/apex

6- The embedded PL/SQL Gateway uses shared server architecture, So ensure not 0 or 1

SELECT NAME, VALUE FROM v$parameter WHERE NAME='shared_servers' If return 0 or 1 run this: ALTER SYSTEM SET SHARED_SERVERS=5 SCOPE BOTH;

Note: be aware EPG on 10g is not supported by Oracle. And not recommend install EPG with 10G.


3-Install oracle APEX and configuring Oracle HTTP Server

1- Download and Install Oracle Apex Software (Steps 1-7 in APEX installation)

2- Download Oracle HTTP Server and install it. the following product include appropriate versions of HTTP Server and mod_plsql:

Oracle Database 10g Companion CD release 2 or Oracle Application Server 10g Oracle Database 11g release 1 or 2

m o c . f f u t s - s p p a . w w w e g a P | 51


3- Copy the image file from APEX folder to the location on the file system containing the Oracle

home for Oracle HTTP Server.

Oracle Application Server 10g Copy images folder to Apache folder

Oracle HTTP Server in 11g Copy images folder to ohs folder

4- Editing the dads.conf file the dads.conf file contains the information about the DAD(database

access descriptor) to access Oracle Application Express

Go to dads.conf file and open it with text editor you find it in \Apache\modplsql\conf\dads.conf (10g), ohs\modplsql\conf\dads.conf(11g)

The content of this file can you copy from below and paste in your dads.conf file after

you change it according your parameters

Replace ORACLE_HTTPSERVER_HOME, host: port: service_name and

apex_public_user_password


Alias /i/ " "ORACLE_HTTPSERVER_HOME/Apache/images/" "

AddType text/xml xbl

AddType text/x-component htc

Order deny,allow

PlsqlDocumentPath docs

Now you can access Oracle APEX by write this URL:

http://hostname:7777/pls/apex/apex

Note: to know what web Server are running in you instance (EPG,APEX Listener or HTTP)

Just go into APEX SQL Workshop -> SQL Commands and enter and execute this:

select owa_util.get_cgi_env('SERVER_SOFTWARE') from dual


Install Oracle Application Express in Oracle 11g

Installation of Oracle Application Express in Oracle Database 11g has become much easier. In Oracle Database 11g, Oracle Application Express is installed when the database is installed. All you need to do is configure the PL/SQL gateway. Before the release of Database 11g, We have to manually run a few scripts to install APEX into Oracle database, and now the common Apex script is executed automatically while using DBCA for 11g (unless you deselect apex in the below step).

Now you want to access oracle APEX must choose whether to use Oracle HTTP server or the embedded light weight PL/SQL gateway to run Apex .it is easier to use embedded PL/SQL gateway. Configure the embedded PL/SQL gateway: In Oracle Database 11g, you configure the embedded PL/SQL gateway by running the configuration script apxconf.sql. Running this script enables you to

configure the port for the Oracle XML DB HTTP server

Specify a password for the Oracle Application Express ADMIN account.

1- Connect to SQL plus as SYSDBA to run apxconf script under the directory of $ORACLE_HOME/apex and run SQL>@apxconf Enter Password when prompted for the ADMIN password, Press enter (to use the 8080 default) when prompted for the port for the XDB HTTP Listener.

2- Unlock the ANONYMOUS Account: ALTER USER ANONYMOUS ACCOUNT UNLOCK;

3- Enable Oracle XML DB HTTP server: EXEC DBMS_XDB.SETHTTPPORT(8080);


4- Now you can access the APEX Page http://host:port/apex

http://host:port/apex/apex_admin , for admin page

Note: you can use Oracle HTTP server with mod_plsql in Oracle Database 11g but is easy to use embedded PL/SQL gateway where it run using Oracle XML DB HTTP server which is already in Oracle

database, so there is no need to install a separate HTTP server.
