• J2EE and Web Cache:

  The J2EE and Web Cache is the smallest of the three installation types and includes the Oracle HTTP Server (OHS), Oracle Containers for Java (OC4J), and the Web Cache components. The components included with this type of installation are considered the base components for all of the midtier and will be included in all other installation types. This type of installation can function as a standalone J2EE server or can be included within an infrastructure instance's farm. It is important to understand that a J2EE and Web Cache installation does not require an infrastructure configuration. When used as a standalone J2EE server, however, you will have to resort to manual configuration and management. If you elect to include this type of installation as a member of a farm, the instance can be configured using the Oracle Enterprise Manager Application Server Control.

• Portal and Wireless:

  This type of installation will include all components of a J2EE and Web Cache installation plus the Portal and Wireless components. Unlike the J2EE and Web Cache installation type, a Portal and Wireless installation type requires access to Oracle's Identity Management and the metadata repository within an infrastructure instance. It is required to have an infrastructure instance installed and configured before performing a Portal and Wireless installation.

• Business Intelligence and Forms:

  This is the largest installation type that includes all midtier components available in Oracle10gAS. The Business Intelligence and Forms installation type includes all components of a Portal and Wireless plus Oracle Application Discoverer, Personalization, Reports Services, and Oracle Forms components. Just like the Portal and Wireless installation type, this type of installation requires access to Oracle's Identity Management and the metadata repository within an infrastructure instance.

• Infrastructure:

  An Infrastruction installation provides many capabilities to most of the midtier components that we have already discussed in the above installation types. In fact, a successful Infrastructure installation is required for two of the three types of midtier installation types. An Infrastructure installation provides access to Oracle's Internet Directory (OID), Identity Management, and the metadata repository for all midtier components.

  When planning the installation of Oracle10gAS you must first determine if you are going to need an Infrastructure. If you are going to be performing either a Portal and Wireless installation or a Business Intelligence and Forms installation, then you have no choice; you must install and configure an Infrastructure instance. If you are going to only perform a J2EE and Web Cache installation, then the Infrastructure instance is optional. If an Infrastructure installation is going to be used, then it must be installed, configured, and running before attempting the midtier installation types.

For the purpose of this article, I will be installing and configuring a Business Intelligence and Forms installation type as well as the required Infrastructure installation. Both instances will be installed on the same MS Windows server.

Screen 2: - Specify File Locations

Enter the Name and Location for the Infrastructure install and hit the <Next> button.

Screen 3: - Select a Product to Install

Select the "OracleAS Infrastructure 10g" option and hit the <Next> button.

Screen 4: - Select Installation Type

Select the "Identity Management and OracleAS Metadata Repository" option and hit the <Next> button.

NOTE: After hitting the <Next> button on my installation, I was prompted with a dialog box indicating that several components are not certified for Windows XP. Since this is a testing server, I simply hit <OK> to continue with the installation.

Screen 5: - Preview of Steps for Infrastructure Installation

Review the steps that the OUI will perform when installing the Infrastructure and hit the <Next> button.

Screen 6: - Select Configuration Options

Select the components you want to configure. By default, the recommended components to configure are already checked. I leave the defaults and hit the <Next> button.

Screen 7: - Specify Namespace in Internet Directory

In most cases, you can leave this option set to its default. It will use the hostname and domain for your server. In my case, I wanted to override this and use a Custom Namespace of idevelopment.info. Select your option and hit the <Next> button.

Screen 8: - Database Identification

This screen allows you to name the Oracle9i database (repository) that will be used to store metadata for the Infrastructure. Keep in mind that Oracle requires you to specify a domain name for the Global Database Name. I appended the idevelopment.info domain name. You should select the appropriate domain name for your environment. Hit the <Next> button.

Screen 9: - Set SYS and SYSTEM Passwords

This screen requires you to enter a password to be used for the SYS and SYSTEM account for the repository database. Enter a valid password and hit the <Next> button.

Screen 10: - Database File Location

Enter the directory name where Oracle should put all database files, control files, and online redo log files for the repository database. I typically keep the default selection. Hit the <Next> button.

Screen 11: - Database Character Set

Enter the Character Set you would like to use for the repository database. I typically keep the default selection. Hit the <Next> button.

Screen 12: - Specify Instance Name and ias_admin Password

This is an important screen. Here you will provide the name of the Infrastructure instance and then provide a password for the ias_admin user id. In this example, I name the Infrastructure instance the same name as the OUI Name for this installation which is 10gASInfrastructure. Also, make sure to take note of the password you provide for the ias_admin user id. You will need this password for managing the Infrastructure instance. Hit the <Next> button.

Screen 13: - Summary

Review the summary screen and hit the <Install> button to begin the installation process.

Installation Process

The OUI provides a screen that allows you to monitor the installation process. This process can take a long time to complete depending on the speed of your server.

Configuration Assistants

Once the installation is complete, the OUI starts the configuration assistants used to set up the application server components. This process configures and deploys those components.

End of Installation

Once all of the configuration assistants have successfully completed, the OUI will display the End of Installation screen. At this point, you should take note of the server ports that have been configured to connect to the Infrastructure Instance and its Oracle Enterprise Manager Application Server Control. The OUI will also log this port information to the ORACLE_HOME\Apache\Apache\setupinfo.txt file.

You can point your browser to the addresses shown to login to the Infrastructure Instance and the Oracle Enterprise Manager Application Server Control. For my installation, I want to test both addresses by using the following:

• Infrastructure Instance

  http://bartman.idevelopment.info:7777

• Oracle Enterprise Manager Application Server Control

  http://bartman.idevelopment.info:1810

Once you have verified that the Infrastructure Instance and the Oracle Enterprise Manager Application Server Control are working, you should go back to the OUI End of Installation screen and hit the <Exit> button.

Also in our configuration, we will be installing the application server middle tier on the same physical server as the Infrastructure instance.

NOTE: Previous versions of Oracle Application Server required you to shut down the Oracle Enterprise Manager web site. This is no longer a requirement with Oracle10gAS. The application server installation process will install over a fully running infrastructure. In most cases, you can simply exit the OUI from the Infrastructure install and restart the installation process for the application server install.

To start the installation process for the application server, change to the same Disk1 directory you used for the Infrastructure install and execute the setup.exe command:

C:\OraInstall\Disk1> setup.exe

    Starting Oracle Universal Installer ...

    Checking requirements...
