This chapter describes how to configure the Oracle Web Tier to support the Oracle Fusion Middleware SOA Suite implementation.
This chapter contains the following sections:
This chapter 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 OHS servers. You created these virtual host names when you configured the load balancer in Section 3.3, "Configuring the Load Balancer."
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 Configuration Wizard to define the instance home, the instance name, and the Oracle HTTP Server component name.
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:
WEBHOST1> cd ORACLE_COMMON_HOME/common/bin
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 the Configure Ports screen, select a file name and then click View/Edit.
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 makes the enterprise deployment much simpler. Oracle allows automatic port configuration to be bypassed by specifying ports to be used in a file.
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:
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.
The instructions for this configuration will vary depending on which load balancer you use. See you load balancer documentation for specific instructions.
To configure the virtual hosts complete the following three tasks as described in this section.
httpd.conf file on both Oracle HTTP Servers
Restart both Oracle HTTP Servers
Validate the configuration
ORACLE_BASE/admin/instance_name/config/OHS/ohs1 (or ohs2)
Add the following entries to the file:
NameVirtualHost *:7777 <VirtualHost *:7777> ServerName https://soa.mycompany.com:443 ServerAdmin email@example.com RewriteEngine On RewriteOptions inherit </VirtualHost> <VirtualHost *:7777> ServerName admin.mycompany.com:80 ServerAdmin firstname.lastname@example.org RewriteEngine On RewriteOptions inherit </VirtualHost> <VirtualHost *:7777> ServerName soainternal.mycompany.com:80 ServerAdmin email@example.com RewriteEngine On RewriteOptions inherit </VirtualHost> #If using OSB <VirtualHost *:7777> ServerName https://osb.mycompany.com:443 ServerAdmin firstname.lastname@example.org RewriteEngine On RewriteOptions inherit </VirtualHost>
Restart both Oracle HTTP Servers after modifying the
httpd.conf files on the WEBHOST:
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.
