2 Installing Oracle Web Tier

2.3.1 For UNIX Platforms

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

2.3.2 For Windows x86 Platforms

On Windows systems, install a loopback adapter on the DHCP server (see Section 2.3.3, "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.

2.3.3 Installing a Loopback Adapter (Windows Only)

2.6.1 Installation Types

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.

For more information, refer to Section 2.6.5, "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 (on UNIX operating systems) or Web_Tier_ORACLE_HOME\bin (on Windows operating systems) 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 2.6.6, "Installation Instructions for the "Install Only" Installation Type"

2.6.2 Installation Log Files

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.

2.6.3 Starting the Installer

To start the installer, insert the CD-ROM and run the following command:

On UNIX operating systems:

% ./runInstaller

On Windows operating systems:

G:\ setup.exe

2.6.4 Inventory Screens (UNIX Only)

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.

2.6.5 Installation Instructions for the "Install and Configure" Installation Type

Follow the instructions in Table 2-2 to install and configure Oracle Web Tier.

If you need additional help with any of the installation screens, refer to Appendix A, "Oracle Web Tier Installation Screens" or click Help to access the online help.

2.6.6 Installation Instructions for the "Install Only" Installation Type

Follow the instructions in Table 2-3 to install Oracle Web Tier.

If you need additional help with any of the installation screens, refer to Appendix A, "Oracle Web Tier Installation Screens" or click Help to access the online help.

After the installation is complete, you must configure the components. This is done by running a separate configuration tool.

On UNIX operating systems:

Web_Tier_ORACLE_HOME/bin/config.sh

On Windows operating systems:

Web_Tier_ORACLE_HOME\bin\config.bat

By default, the configuration tool will use the Oracle JRockit SDK that can be found inside the Middleware Home directory. If you want to invoke the configuration tool with a Sun JDK, you must point to the specific JDK from the command line:

On UNIX operating systems:

Web_Tier_ORACLE_HOME/bin/config.sh -jreLoc Sun_JDK_Location

On Windows operating systems:

Web_Tier_ORACLE_HOME\bin\config.bat -jreLoc Sun_JDK_Location

You must specify the full path to your Sun JDK location.

After you have started the configuration tool, follow the instructions in Table 2-4.

2.7.1 Configuring Routing Between Oracle HTTP Server and Oracle WebLogic Server

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.

2.7.2 Using Oracle Web Cache with Oracle BAM

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 

2.8.1 Verify the Installation Logs

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.

2.8.2 Verifying the Domain Server 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

2.8.3 Verifying OPMN Status

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.

2.8.4 Check Browser URLs

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
