This chapter describes how to configure the Oracle web tier to support the Oracle Fusion Middleware WebCenter Content implementation.
This chapter contains the following sections:
Before configuring the Oracle Web Tier software, you must install it on WEBHOST1 and WEBHOST2, as described in Section 6.2, "Installing Oracle HTTP Server." Run the Fusion Middleware Configuration Wizard to define the instance home, the instance name, and the Oracle HTTP Server component name.
This chapter also describes how to associate the Oracle web tier with the WebLogic Server domain. Once the web tier is associated with the WebLogic Server, you can monitor it using the Oracle Fusion Middleware Console.
You then configure the load balancer to route all HTTP requests to WEBHOST1 and WEBHOST2.
The last section describes how to define the directives of the
<VirtualHost> section of the httpd.conf file on both Oracle HTTP Servers. You created these virtual host names when you configured the load balancer in Section 3.3, "Configuring the Load Balancer."
The steps for configuring the Oracle Web Tier are the same for both WEBHOST1 and WEBHOST2.
To configure the Oracle Web Tier:
Change the directory to the location of the Oracle Fusion Middleware Configuration Wizard:
Start the Configuration Wizard:
In the Welcome screen, click Next.
In the Configure Components screen, select Oracle HTTP Server and unselect Associate Selected Components with WebLogic Domain. Make sure that Oracle Web Cache is not selected.
In the Specify Component Details screen, specify the following values:
Instance Home Location: ORACLE_BASE/admin/webn
AS Instance Name: webn
OHS Component Name: ohsn
(where n is a sequential number for your installation; for example, 1 for WEBHOST1, 2 for WEBHOST2, and so on.)
Oracle HTTP Server instance names on WEBHOST1 and WEBHOST2 must be different.
In high-availability implementations, it is not mandatory for all of the ports used by the various components to be synchronized across hosts. However, it does make the enterprise deployment much simpler. Oracle allows automatic port configuration to be bypassed by specifying ports to be used in a file.
In the Configure Ports screen, select a file name and then click View/Edit. The file will look like this:
[OHS] #Listen port for OHS component OHS Port = 7777 [OPMN] #Process Manager Local port no OPMN Local Port = 1880
You can find a sample staticports.ini file on installation disk 1 in the stage/Response directory.
In the Specify Security Updates screen, choose whether you want to receive security updates from Oracle support and if you do, enter your e-mail address.
In the Installation Summary screen, review the selections to ensure they are correct. If they are not, click Back to modify selections on previous screens. When you are ready, click Configure.
Multiple configuration assistants are launched in succession; this process can be lengthy. When it completes, click Next, and the Installation Complete screen appears.
In the Installation Completed screen, click Finish to exit.
Once the installation is completed, check that it is possible to access the Oracle HTTP Server home page using the following URL:
Once an Oracle WebLogic domain has been created, the Oracle web tier can be linked to the domain. The advantages of doing this are that the Oracle web tier can be managed and monitored via the Oracle Fusion Middleware console.
To associate the Oracle web tier with the WebLogic domain, execute the following commands on both WEBHOST1 and WEBHOST2:
cd ORACLE_BASE/admin/instance_name/bin ./opmnctl registerinstance -adminHost ADMINVHN -adminPort 7001 -adminUsername weblogic
Configure your load balancer to route all HTTP requests to the hosts running Oracle HTTP Server (WEBHOST1, WEBHOST2). You do not need to enable sticky sessions (insert cookie) on the load balancer when Oracle HTTP Server is front-ending Oracle WebLogic Server. You need sticky sessions 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, you should set monitors for HTTP.
The instructions for this configuration will vary depending on which load balancer you use. See your load balancer documentation for specific instructions.
To configure the virtual hosts complete the following three tasks:
In order for Oracle WebCenter Content to work with the load balancer, virtual hosts need to be created in the Oracle HTTP Server configuration. Edit the httpd.conf file located in ORACLE_INSTANCE/config/OHS/ohs1 (or ohs2) and add the following entries to the
NameVirtualHost *:7777 <VirtualHost *:7777> ServerName https://wcc.mycompany.com:443 RewriteEngine On RewriteOptions inherit UseCanonicalName On </VirtualHost> NameVirtualHost *:7777 <VirtualHost *:7777> ServerName admin.mycompany.com:80 RewriteEngine On RewriteOptions inherit UseCanonicalName On </VirtualHost> NameVirtualHost *:7777 <VirtualHost *:7777> ServerName soainternal.mycompany.com:80 RewriteEngine On RewriteOptions inherit UseCanonicalName On </VirtualHost>
Restart both Oracle HTTP Servers after modifying the httpd.conf files. On both WEBHOST1 and WEBHOST2, execute the following commands:
cd ORACLE_BASE/admin/instance_name/bin opmnctl stopall opmnctl startall
Access the following URLs to ensure that your load balancer and Oracle HTTP Server are configured properly:
If you cannot access these URLs, check to ensure that you completed the procedure in Section 3.3, "Configuring the Load Balancer" correctly.
