This chapter describes how to install the Oracle Web Tier components. During the install and configuration process, you will have the option to install and configure the following products:
Oracle HTTP Server (OHS)
Oracle Web Cache
Oracle Process Manager and Notification Server (OPMN) is installed and configured by default.
The following topics are covered:
Make sure you have read "Before you Begin" in Oracle Fusion Middleware Installation Planning Guide before you install Oracle Web Tier.
In addition, you should also check the following prior to installation:
Section 2.1.1, "Installing 32-bit Oracle Web Tier on a 64-bit Operating System"
Section 2.1.2, "Oracle Fusion Middleware Support of 64-bit JDK"
This section contains important information regarding the installation of 32-bit Oracle Web Tier products on a 64-bit operating system. If this does not describe your environment, you can skip this section.
If you are installing the 32-bit version of the product on a Windows operating system, the system on which you are installing must also be a supported 32-bit system. Installing a 32-bit version of the product on a 64-bit system is not supported.
A 32-bit Linux version of Oracle Web Tier may be installed on most 64-bit Linux platforms. To see which platforms are supported, refer to the "System Requirements and Supported Platforms for Oracle Fusion Middleware 11gR1" document, available on the following page:
http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html
To install your 32-bit Oracle Web Tier software on a certified 64-bit Linux system, do the following:
Run the following command before starting the installer:
linux32 bash
During the installation, you will receive an error during the linking phase. To work around this error:
Login as root user.
Move the existing /usr/bin/gcc file to /usr/bin/gcc.orig with the mv command:
mv /usr/bin/gcc /usr/bin/gcc.orig
Using a text editor such as vi, create a new file called gcc41 that contains the following content:
#!/bin/sh exec /usr/bin/gcc.orig -m32 -static-libgcc -B /usr/lib/gcc/i586-suse-linux/2.95.3/ $*
Note:
The filei586-suse-linux/2.95.3 may differ slightly depending on the exact version of your Linux operating system. Verify the exact version of your Linux operating system in use; search for the 32bit directory in /usr/lib/gcc and obtain the exact file name.Change the file permission for the gcc41 file using the following command:
chmod 755 /usr/bin/gcc41
Create a symbolic link to /usr/bin/gcc with the following command:
ln -s -f /usr/bin/gcc41 /usr/bin/gcc
If you are using a 64-bit JVM in your environment, ensure that all your Oracle Fusion Middleware components are using the 64-bit JVM. You cannot mix components using a 32-bit JVM with those using a 64-bit JVM.
For more information, refer to the "System Requirements and Supported Platforms for Oracle Fusion Middleware 11gR1" document, available on the following page:
http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html
If your Oracle Fusion Middleware components are running in a 64-bit JVM environment, ensure that WebLogic Server is installed with the 64-bit JDK. For 32-bit JVM support, refer to the Oracle Fusion Middleware Release Notes for information on how to configure your environment for 32-bit JVM support for your platform.
The Oracle Web Tier installer provides two installation options:
Install and Configure
This 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.
Install Software - Do Not Configure
This option only installs the software binaries in an Oracle home directory. You must then manually run the Configuration Tool from the bin directory in your Web Tier Oracle home 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.
To install the latest Oracle Web Tier software, you must choose the Install Software - Do Not Configure installation type, as described in Section 1.4, "Installation Roadmaps".
If you are installing Oracle Web Tier and associating the components with a WebLogic Server domain, you will need to do the following:
Creating a WebLogic Server Domain for your Oracle Web Tier Components
Starting Node Manager When Registering Oracle Web Tier with a WebLogic Server Domain
If you do not already have a WebLogic Server domain to associate with your Oracle Web Tier components, you can create one as follows:
Install certified versions of a JDK and Oracle WebLogic Server.
Install (do not configure) any Oracle Fusion Middleware product, including Oracle Web Tier.
Installation of an Oracle Fusion Middleware product creates the Oracle Common home directory (MW_HOME/oracle_common on UNIX operating systems, or MW_HOME\oracle_common on Windows operating systems). This directory contains the domain templates for Enterprise Manager and Java Required Files (JRF).
Run the Configuration Wizard from the Oracle Common home directory (config.sh on UNIX operating systems or config.cmd on Windows operating systems).
On the Select Domain Source screen, select the Oracle Enterprise Manager and Oracle JRF templates associated with the oracle_common directory. The Oracle JRF template is selected automatically when the Oracle Enterprise Manager template is selected.
After the installation is complete, start the Administration Server in the domain, and then verify that the Oracle Web Tier components are listed by accessing the following URL:
http://host:port/em
If you are registering your Oracle Web Tier instance with an existing WebLogic Domain, you must start Node Manager as described below:
On UNIX operating systems, run the ORACLE_HOME/common/bin/setNMProps.sh script.
On Windows operating systems, run the ORACLE_HOME\common\bin\setNMProps.cmd script.
This script appends the required properties to the nodemanager.properties file. These properties can also be appended manually, or provided as command-line arguments.
Note:
TheStartScriptEnabled=true property is required for Managed Servers to receive proper classpath and command arguments.On UNIX operating systems, start Node Manager by running the WebLogic_Server_Home/server/bin/startNodeManager.sh script.
On Windows operating systems, start Node Manager by running the WebLogic_Server_Home\server\bin\startNodeManager.cmd script.
For more information about Node Manager, refer to Oracle Fusion Middleware Node Manager Administrator's Guide for Oracle WebLogic Server.
This section contains information and instructions for installing Oracle Web Tier. The following topics are covered:
See "Obtain the Oracle Fusion Middleware Software" in Oracle Fusion Middleware Installation Planning Guide for information on where to obtain the software.
Select one of the download locations and download "Oracle Web Tier." This will be saved to your system as a .zip archive file.
After you download the archive file, unpack the archive file into a directory of your choice on the machine where you will be performing the installation.
To start the installer, go to the directory where you unpacked the archive file and switch to the Disk1 directory.
If you are installing on an IBM AIX operating system, you must run the rootpre.sh script from the Disk1 directory before you start the installer.
Start the installer from the Disk1 directory:
On UNIX operating systems:
./runInstaller
On Windows operating systems:
setup.exe
Note:
Running the installer asroot user is not supported.The installer writes logs files to the Oracle_Inventory_Location/log (on UNIX operating systems) or Oracle_Inventory_Location\logs (on Windows operating systems) directory. Refer to Section D.2.1, "Installation Log Files" for more information about the log files and their contents.
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.

When configuration is complete, go to Section 2.5, "Post-Installation Tasks".
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 (on UNIX operating systems) or INSTANCE_HOME\bin (on Windows operating systems) 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 (on UNIX operating systems) or INSTANCE_HOME\bin (on Windows operating systems) 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
