Perform the following steps to test that you can connect to Oracle Database XE.
To test that Oracle Database XE is accessible, connect to the database using the Oracle Database XE home page:
In a browser, enter the URL for your Oracle Database Express Edition home page:
http://localhost:8080/htmldb
In the Oracle Database XE Login page, enter hr in the Username and Password fields. Click Login:
The Oracle Database XE Home page appears:
If the message, Invalid Login Credentials appears, you may need to unlock the HR user. See Unlocking the HR User following.
Click the Logout link to terminate the HTMLDB session.
The Logout Confirmation page appears:
The PHP application connects to the database as the HR user. You may need to unlock the HR account as a user with DBA privileges. To unlock the HR user:
In a browser, enter the URL for your Oracle Database Express Edition home page:
http://localhost:8080/htmldb
At the login screen, in the Username field enter system, and in the Password field enter manager (or the password you entered at the prompt during configuration of Oracle Database XE). Click Login.
In the Home page, click the arrow on the Administration icon, move the mouse over Database Users, and click Manage Users:
In the Manage Users page, click the HR user icon:
In the Manage Database User page, select Unlocked from the Account Status list and then click the Alter User button. The message User Altered appears below the navigation breadcrumb toward the top of the page.
Click the Logout link to terminate the HTMLDB session.
For further information about unlocking an Oracle Database account, see Chapter 6, "Managing Users and Security," in the Oracle Database Express Edition 2 Day DBA guide.
You can download Apache for Windows or Linux from:
Apache is normally a standard part of a Linux environment.
Install Apache following the instructions available from the same site.
To test the Apache Web server installation:
Start your Web browser on the host on which you installed Apache.
Enter the following URL:
http://localhost/
Your browser should display a page similar to the following:
If this page does not appear check your Apache configuration. Common problems are that Apache is not running, or that it is listening on a non-default port.
To test the Apache Web server installation:
Start your Web browser on the host you installed Apache on, and enter the following URL:
http://localhost/
Your browser should display a page similar to the following:
If this page does not appear check your Apache configuration. Common problems are that Apache is not running, or that it is listening on a non-default port.
In the default Apache Web server configuration file, set up a public virtual directory as public_html for accessing your PHP files. Use your preferred editor to open the Apache configuration file /etc/httpd/conf/httpd.conf (the directory may be different in your installation of Linux) and remove the "#" character at the start of the following line:
#UserDir public_html
This enables the browser to make an HTTP request using a registered user on the system and to serve files from the $HOME/public_html directory of the user. For example:
http://localhost/~user/
In this example, your Apache httpd.conf file should contain the following lines:
<IfModule mod_userdir.c>
#
# UserDir is disabled by default since it can confirm the presence
# of a username on the system (depending on home directory
# permissions).
#
#UserDir disable
#
# To enable requests to /~user/ to serve the user's public_html
# directory, remove the "UserDir disable" line above, and uncomment
# the following line instead:
#
UserDir public_html
</IfModule>
In a command window, to use the new Apache configuration file, restart Apache by entering the following commands:
su - Password: <enter your su (root) password> apachectl restart
If the Apache Web server does not start, check the error log files to determine the cause. It may be a configuration error.
In the command window, log in as a normal (not root) user and create a public_html subdirectory in the $HOME directory with the following command:
mkdir $HOME/public_html
