If you are installing Oracle Web Tier on a DHCP host, you must follow the configuration steps in this section for your platform.
On UNIX systems, configure the host to resolve hostnames to the loopback IP address by modifying the /etc/hosts file to contain the following entries:
127.0.0.1 hostname.domainname hostname 127.0.0.1 localhost.localdomain localhost
After doing so, check that the hostname resolves to the loopback IP address by entering the following command:
/bin/ping hostname.domainname
On Windows systems, install a loopback adapter on the DHCP server (see Section 2.2.3, "Installing a Loopback Adapter (Windows Only)"). This assigns a local IP address to your computer.
After installing the adapter, add a line to the %SYSTEMROOT%\system32\drivers\etc\hosts file with the following format, immediately after the localhost line:
IP_address hostname.domainname hostname
Replace IP_address with the local IP address of the loopback adapter.
To install a loopback adapter on Windows 2003 or Windows XP:
Open the Windows Control Panel.
Windows 2003: Select Start > Control Panel > Add Hardware.
Windows XP: Select Start > Control Panel, then double-click Add Hardware.
In the "Welcome" window, click Next.
In the "Is the hardware connected?" window, select Yes, I have already connected the hardware, then click Next.
In the "The following hardware is already installed on your computer" window, in the list of installed hardware, select Add a new hardware device, then click Next.
In the "The wizard can help you install other hardware" window, select Install the hardware that I manually select from a list, then click Next.
In the "From the list of hardware types, select the type of hardware you are installing" window, select Network adapters, then click Next.
In the "Select Network Adapter" window, make the following selections:
Manufacturer: Microsoft
Network Adapter: Microsoft Loopback Adapter
Click Next.
In the "The wizard is ready to install your hardware" window, click Next.
In the "Completing the Add Hardware Wizard" window, click Finish.
If you are using Windows 2003, restart your computer.
Right-click My Network Places on the desktop and choose Properties. This displays the Network Connections Control Panel.
Right-click the connection that was just created. This is usually named "Local Area Connection 2". Choose Properties.
On the "General" tab, select Internet Protocol (TCP/IP), then click Properties.
In the "Properties" dialog box, click Use the following IP address and do the following:
IP Address: Enter a non-routable IP for the loopback adapter. Oracle recommends the following non-routable addresses:
192.168.x.x (x is any value between 1 and 255) 10.10.10.10
Subnet mask: Enter 255.255.255.0.
Record the values you entered, which you will need later in this procedure.
Leave all other fields empty.
Click OK.
In the "Local Area Connection 2 Properties" dialog, click OK.
Close Network Connections.
Restart the computer.
To remove a loopback adapter on Windows 2003 or Windows XP:
Start the System Control panel.
Windows 2003: Select Start > Control Panel > System.
Windows XP: Select Start > Control Panel, then double-click System.
In the "Hardware" tab, click Device Manager.
In the "Device Manager" window, expand Network adapters. You should see Microsoft Loopback Adapter.
Right-click Microsoft Loopback Adapter and select Uninstall.
Click OK.
You can install Oracle Portal, Forms, Reports and Discoverer on a non-networked computer, such as a laptop. Because a non-networked computer has no access to other computers, you have to install all the components that you need on the computer.
In addition, you must follow the instructions in Section 2.2, "Installing on DHCP Hosts" to install a loopback adapter and modify the hosts file on your system.
You can install Oracle Web Tier on a multihomed computer. A multihomed computer is associated with multiple IP addresses. This is typically achieved by having multiple network cards on the computer. Each IP address is associated with a host name; additionally, you can set up aliases for each hostname.
The installer picks up the fully qualified domain name from the first entry in /etc/hosts (on UNIX) or %SYSTEMROOT%\system32\drivers\etc\hosts (on Windows) file. So if your file looks like the following:
127.0.0.1 localhost.localdomain localhost 10.222.333.444 myhost1.mycompany.com myhost1 20.222.333.444 devhost2.mycompany.com devhost2
myhost1.mycompany.com would be picked for configuration.
For specific network configuration of a system component, refer to the individual component's configuration documentation.
This section contains information and instructions for installing Oracle Web Tier. The following topics are covered:
Section 2.5.5, "Installation Instructions for the "Install and Configure" Installation Type"
Section 2.5.6, "Installation Instructions for the "Install Only" Installation Type"
The Oracle Web Tier installer provides two installation options:
Installation Instructions for the "Install and Configure" Installation Type
Installation Instructions for the "Install Only" Installation Type
The Install and Configure option will install the product binaries in an Oracle Home directory and create and configure a working instance in an Oracle Instance directory. After this is complete, you should be able to begin configuring and managing your products using the Administration Console or Enterprise Manager.
Note:
For more information about Oracle Home and Oracle Instance directories, refer to "Installation Overview" in Oracle Fusion Middleware Installation Planning Guide.For more information, refer to Section 2.5.5, "Installation Instructions for the "Install and Configure" Installation Type"
The Install Software - Do Not Configure option only installs the software binaries in an Oracle Home directory. You must then manually run the Configuration Tool from your Web_Tier_ORACLE_HOME/bin (for UNIX) or Web_Tier_ORACLE_HOME\bin (for Windows) directory to configure your products before you can use them. This option can be used to quickly create multiple instances of the software that share a common disk.
For more information, refer to Section 2.5.6, "Installation Instructions for the "Install Only" Installation Type"
The installer writes logs files to the Oracle_Inventory_Location/log (for UNIX) or Oracle_Inventory_Location\logs (for Windows) directory. On UNIX systems, if you do not know the location of your Oracle Inventory directory, you can find it in the Web_Tier_ORACLE_HOME/oraInst.loc file. On Windows systems, the default location for the inventory directory is C:\Program Files\Oracle\Inventory\logs.
The following install log files are written to the log directory:
installdate-time-stamp.log
installdate-time-stamp.out
installActionsdate-time-stamp.log
installProfiledate-time-stamp.log
oraInstalldate-time-stamp.err
oraInstalldate-time-stamp.log
If you start the installer with the -printtime parameter, the timeTakendate-time-stamp.log file is created in the same directory.
To start the installer, insert the CD-ROM and run the following command:
On UNIX:
% ./runInstaller
On Windows:
G:\ setup.exe
If you are installing on a UNIX system, and if this is the first time any Oracle product is being installed on your system with the Oracle Universal Installer, you will be asked to provide the location of an inventory directory. This is where the installer will set up subdirectories and maintain inventory data for each Oracle product that is installed on this system.
Follow the instructions in Table 2-1 to configure the inventory directory information. For more help, click on the screen name in the table below, or click the Help button in the GUI.

After installation and configuration are complete, there may be some post-installation tasks you need to perform, depending on your specific topology and configuration. The following topics are covered in this section:
By default, routing between Oracle HTTP Server and Oracle WebLogic Server is not configured. In order to allow requests to be proxied from Oracle HTTP Server to Oracle WebLogic Server, you must configure a plug-in.
For instructions on how to do this, see "mod_wl_ohs" in the Oracle Fusion Middleware Administrator's Guide for Oracle HTTP Server.
If you are using Oracle Web Cache with Oracle BAM, you must perform the configuration steps detailed in "Basic Tasks for Configuring and Monitoring Caching Rules" in Oracle Fusion Middleware Administrator's Guide for Oracle Web Cache.
Use the following Oracle BAM settings:
Expression Type : Regular Expression URL Expression : oracle.bam.web (or Event=viewReport, for the second rule) HTTP Methods : Select all Leave URL and POST Body Parameters empty. POST Body Expression : .* Caching Policy : Don't Cache Leave Comment as it is. Compression : Off Enabled : yes
You can perform any combination of the following tasks to verify that your installation was successful:
Check for the presence of installation log files in logs directory inside your Oracle Inventory directory. On UNIX systems, if you do not know the location of your Oracle Inventory directory, you can find it in the WebTier_ORACLE_HOME/oraInst.loc file. On Windows systems, the default location for the inventory directory is C:\Program Files\Oracle\Inventory\logs.
Check the domain server logs, which are located in the servers directory inside the domain home directory. For example, on UNIX systems:
Web_Tier_ORACLE_HOME/user_projects/domains/domain_name/servers/server_name
On Windows systems:
Web_Tier_ORACLE_HOME\user_projects\domains\domain_name\servers\server_name
Run the opmnctl status command from the INSTANCE_HOME/bin (for UNIX) or INSTANCE_HOME\bin (for Windows) directory in your instance home location. For example:
> ./opmnctl status Processes in Instance: instance2 ---------------------------------+--------------------+---------+--------- ias-component | process-type | pid | status ---------------------------------+--------------------+---------+--------- webcache1 | WebCache-admin | 24057 | Alive webcache1 | WebCache | 24056 | Alive ohs1 | OHS | 23890 | Alive
This information shows the components configured for this installation. The status "Alive" means the component is up and running.
Run the opmnctl status -l command from the INSTANCE_HOME/bin (for UNIX) or INSTANCE_HOME\bin (for Windows) directory in your instance home location to obtain a list of ports used by the components. For example:
> ./opmnctl status -l ---------------------------------+--------------------+---------+----------+------------+----------+-----------+------ ias-component | process-type | pid | status | uid | memused | uptime | ports ---------------------------------+--------------------+---------+----------+------------+----------+-----------+------ webcache1 | WebCache-admin | 24057 | Alive | 1067146469 | 43712 | 14:43:29 | http_admin:7799 webcache1 | WebCache | 24056 | Alive | 1067146468 | 64072 | 14:43:29 | http_stat:7800,http_invalidation:7801,https_listen:7802,http_listen:7798 ohs1 | OHS | 23890 | Alive | 1067146467 | 50260 | 14:43:39 | https:9999,https:4447,http:7777
