5 Configuring the Web Tier

5.1 Configuring the Web Tier

This chapter describes how to configure the Oracle Web Tier.

Follow these steps to configure the Oracle HTTP Server on Webhost1 and Webhost2.

Prior to configuring the Oracle Web Tier software must have been installed on WEBHOST1 and WEBHOST2 as described in Chapter 4, "Installing the Software."

5.2 Configuring the Oracle Web Tier

The steps for configuring the Oracle Web Tier are the same for both webhost1 and webhost2.

Perform these steps to configure the Oracle web tier:

1. Change the directory to the location of the Oracle Fusion Middleware Configuration Wizard:

   WEBHOST1> cd ORACLE_HOME/bin
   

2. Start the Configuration Wizard:

   WEBHOST1> ./config.sh
   

Enter the following information into the configuration wizard:

1. On the Welcome screen, click Next.

2. On the Configure Component screen, select: Oracle HTTP Server.

   Ensure that Associate Selected Components with WebLogic Domain is not selected.

   Ensure Oracle Web Cache is NOT selected.

   Click Next.

3. On the Specify Component Details screen, specify the following values:

   Enter the following values for WEBHOST1:

   • Instance Home Location: /u01/app/oracle/admin/ohs_inst1

   • Instance Name: ohs_inst1

   • OHS Component Name: ohs1

   Enter the following values for WEBHOST2:

   • Instance Home Location: /u01/app/oracle/admin/ohs_inst2

   • Instance Name: ohs_inst2

   • OHS Component Name: ohs2

   Click Next.

4. On the Configure Ports screen, use a file to specify the ports to be used so that you can bypass automatic port configuration. You do this in order to have all of the ports used by the various components synchronized across hosts, which is advisable but not mandatory in High Availability implementations, Select a file name and then click View/Edit. Enter the following text into the file:

   [OHS]
   #Listen port for OHS component
   OHS Port = 7777
   [OPMN]
   #OPMN Local port no
   OPMN Local Port = 6700
   

   You can find a sample staticports.ini file on installation Disk1 in the stage/Response directory.

   Click Save, then click Next.

5. On the Specify Security Updates screen, specify these values:

   • Email Address: The email address for your My Oracle Support account.

   • Oracle Support Password: The password for your My Oracle Support account.

   Select: I wish to receive security updates via My Oracle Support.

   Click Next.

6. On the Installation Summary screen, review the selections to ensure that they are correct. If they are not, click Back to modify selections on previous screens.

   Click Install.

   On the Configuration screen, the wizard launches multiple configuration assistants. This process can be lengthy. When it completes, click Next.

   On the Installation Complete screen, click Finish to confirm your choice to exit.

5.3 Configuring Oracle HTTP Server with the Load Balancer

Configure your load balancer to route all HTTP requests to the hosts running Oracle HTTP Server, that is, WEBHOST1 and WEBHOST.

You do not need to enable sticky session (insert cookie) on the load balancer when Oracle HTTP Server is the front end to Oracle WebLogic Server. You need sticky session if you are going directly from the load balancer to Oracle WebLogic Server, which is not the case in the topology described in this guide.

Also, set Monitors for HTTP.

5.4 Configuring Virtual Hosts

In order for Oracle Identity Management Suite to work with the load balancer, you must create two virtual hosts.

To do so, create a file called virtual_hosts.conf in ORACLE_INSTANCE/config/OHS/component/moduleconf.

On WEBHOST1, add the following entries to the file:

NameVirtualHost *:7777
<VirtualHost *:7777> 
   ServerName https://sso.mycompany.com:443
   RewriteEngine On
   RewriteOptions inherit
   UseCanonicalName On
</VirtualHost>
<VirtualHost *:7777>
   ServerName http://oim.mycompany.com:80
   RewriteEngine On
   RewriteOptions inherit
   UseCanonicalName On
</VirtualHost>

5.5 Validating the Installation

Once the installation is completed check that the it is possible to access the Oracle HTTP Server via the following URL's:

http://webhost1.mycompany.com:7777/

http://webhost2.mycompany.com:7777/

https://sso.mycompany.com/

http://oiminternal.mycompany.com

5.6 Backing up the Web Tier Configuration

It is an Oracle best practices recommendation to create a backup after successfully completing the installation and configuration of each tier, or at another logical point. Create a backup after verifying that the installation so far is successful. This is a quick backup for the express purpose of immediate restoration in case of problems in later steps. The backup destination is the local disk. You can discard this backup when the enterprise deployment setup is complete. After the enterprise deployment setup is complete, you can initiate the regular deployment-specific Backup and Recovery process. For more details, see the Oracle Fusion Middleware Administrator's Guide.

To back up the web tier installation, follow these steps,

1. Shut down the instance as described in Section 19.1, "Starting and Stopping Oracle Identity Management Components."

2. Back up the Middleware home on the web tier using the following command, as root:

   tar -cvpf BACKUP_LOCATION/web.tar MW_HOME
   

3. Back up the Instance home on the web tier using the following command, as root:

   tar -cvpf BACKUP_LOCATION/web_instance.tar ORACLE_INSTANCE
   

4. Start the instance as described in Section 19.1, "Starting and Stopping Oracle Identity Management Components."

For information about backing up the application tier configuration, see Section 19.4, "Performing Backups and Recoveries."
