How to install Apex5 with Oracle REST Data Services in windows

Category : Oracle | Tag : Oracle | Apex | Rest Data Service |

Installing Apex5

Before installing apex 5 you should determine which Web listener you would like to use. Available options include the followings -

In all of these options Apex installation procedure is same and configuring Embedded PL/SQL Gateway is simpler. Embedded PL/SQL gateway provides the equivalent core features of Oracle HTTP Server and MOD_PLSQL. In this article I’ll install apex 5 and configure the Oracle REST Data Services with tomcat server. In this case I've used

N.B. I’ve discussed on Apex 4.2 installation with Embedded PL/SQL Gateway configuration here
Remember I’ll not discus about installing database. I assume that you have a database already installed and you have the administrative privileges on the database. Also assume that you have downloaded apex. If not so, you may get a copy of Oracle Apex 5.0 on OTN

Steps to install Oracle Apex 5

 

Step 1: Login to database and create a table space (e.g.TS_APEX). Table space creating command is as below

CREATE TABLESPACE ts_apex 
DATAFILE 'C:\APP\ADMINISTRATOR\ORADATA\CANOPAS\TS_APEX01.DBF' 
SIZE 2048M AUTOEXTEND ON NEXT 100M 
MAXSIZE UNLIMITED
LOGGING
ONLINE
PERMANENT
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
BLOCKSIZE 8K
FLASHBACK ON;
Step 2: Unzip the apex folder. (Right click on apex_5.0.zip folder then choose extract here) you will find
a folder named apex. Copy this folder anywhere on your hard drive you wish. In my case I’ve put it in H:\SoftWare\Apex\apex.

Step 3: Open Command Prompt (cmd). Change your working directory to apex where you put the unzipped apex
folder (in my case it is H:\SoftWare\Apex\apex). Below images showing the command


Step 4: Now open SQL*Plus with nolog option by executing the command

 H:\SoftWare\Apex\apex> sqlplus /nolog
Then  
SQL> conn sys as sysdba
(To connect to database with sysdba privileges) When password require enter sys user’s password.

Step 5: Now you need to run apex installation file named apexins.sql. in command prompt enter the command like below

 SQL> @apexins.sql ts_apex ts_apex temp /i/

 [Here  
APEXINS.SQL is the apex main installation file.
TS_APEX is the table space name which we creates at first step for apex user,
temp is also a table space for apex temporary file.
/i/ is a virtual drive for images.
]
It may take 20/30 minutes and may be disconnect from database. Remember whenever you disconnect from database every time you must follow the step (3, 4) to connect again. When Oracle Application Express installed, it creates three new database accounts:

When installation is finished it shows message like flowing image

In a new installation of Oracle Application Express, you must change the password of the internal ADMIN account. To changes password connect to database again and run the flowing command

SQL> @apxchpwd

When prompted enter a password for the ADMIN account. It should be complex password like abcd#1234 Also you need to unlock APEX_PUBLIC_USER. To unlock account execute the following command

ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK;

ALTER USER APEX_PUBLIC_USER IDENTIFIED BY new_password;

Configuring Restful Services

To configure oracle restful service connect to the database as sysdba and enter the following command

SQL> @apex_rest_config.sql

Enter a password for the APEX_LISTENER user              []
Enter a password for the APEX_REST_PUBLIC_USER user              []

Installing and Configuring Oracle Rest Data Services

A. Download the file ” ords.version.number.zip” from the Oracle REST Data Services download page
B. Unzip the downloaded zip file into a directory (folder) of your choice. I put it in E:\ords.3.0.3.351.13.24. Actually there is nothing to install, that means your installation is done. Now you need to configure the Rest Data Service.

N.B.
B.I. By default, the context roots for accessing Oracle Application Express through Oracle REST Data Services is …/ords. If you wish to have a context root of … /apex for accessing Oracle Application Express, rename the file ords.war (E:\ords.3.0.3.351.13.24\ords.war) to apex.war before installing Oracle Rest Data Service. If you change the ords.war to apex.war then change the file ords_params.properties. Open the ords_params.properties file (location E:\ords.3.0.3.351.13.24\params) enter the line as it is here: rest.services.apex.add=true
 
B.II. Create a folder named config in the rest data service folder (E:\ords.3.0.3.351.13.24\config) to store rest data service configuration data. Later this location will be needed during configuration. Remember you can provide any location in your hard drive. To keep it in one place I've create this folder in ords.3.0.3.351.13.24 folder

C. following are the Installation/configuration options-

We will Choose 'Advanced Installation/configuration Using Command-Line Prompts' from these options

Now open cmd and change your working directory to the directory or folder containing the ords.war file (in my case it is E:\ords.3.0.3.351.13.24). If you don't have rename ords.war to apex.war then enter the following command  

N.B. Before executing following command you need to install java.
E:\ords.3.0.3.351.13.24> java -jar ords.war install advanced

if you have rename ords.war to apex.war then enter the following command
E:\ords.3.0.3.351.13.24> java -jar apex.war install advanced

It will prompt you for some configuration information. Here I’ve showed the full prompt and what I selected.
This Oracle REST Data Services instance has not yet been configured. Please complete the following prompts

Enter the location to store configuration data:D:\Oracle\RestDataService\ords.3.0.3.351.13.24\config

Confirm password:
Please login with SYSDBA privileges to verify Oracle REST Data Services schema. Installation may be required.
Enter the username with SYSDBA privileges to verify the installation [SYS]:

Confirm password:
Enter 1 if you want to use PL/SQL Gateway or 2 to skip this step. If using Oracle Application Express or migrating from mod_plsql then you must enter 1 [1]:
Enter the PL/SQL Gateway database user name [APEX_PUBLIC_USER]:
Enter the database password for APEX_PUBLIC_USER:
Confirm password:
Enter 1 to specify passwords for Application Express RESTful Services database users (APEX_LISTENER, APEX_REST_PUBLIC_USER) or 2 to skip this step [1]:
Enter the database password for APEX_LISTENER:
Confirm password:
Enter the database password for APEX_REST_PUBLIC_USER:
Confirm password:

Enter 1 if you wish to start in standalone mode or 2 to exit [1]:2

Installing Apache Tomcat Application Server

To download tomcat go to tomcat site. From left side click on your desired version number. On the next page click on 32-bit/64-bit windows service installer it will download the tomcat .exe for windows. Now install tomcat by running downloaded (.exe) file

1. Deploying to Apache Tomcat

To configure Oracle Application Express Images on Apache Tomcat: Create a folder into /webapps (in my case it is E:\Tomcat 9.0\webapps) named i. Copy the contents from the /images folder (in my case it is H:\SoftWare\Apex\apex\images) to /webapps/i/.

Installing the Apache Tomcat Deployment

Move the ords.war or apex.war file from rest data service into tomcat’s webapps folder (/webapps) folder where Apache Tomcat is installed Access Oracle Application Express by typing the following URL in your web browser: 
http://hostname:port/ords/ or 
http://hostname:port/apex/ 

Removing Oracle Application Express from the Database

  1. Change your working directory to the apex directory where you unzipped the Oracle Application Express software.
  2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role:sqlplus /nolog

    SQL> CONNECT SYS as SYSDBA
    Enter password: SYS_password
     
  3. Execute the following command:
    SQL> @apxremov.sql 
    
  4. After successfully removing Application Express using apxremov.sql, you must exit your current SQL*Plus session and reconnect before attempting another install using apexins.sql.
