Choosing the Platform Components
The platform components provide the internet infrastructure necessary for your Windchill solution installation.
PSI allows you to select and configure the required platform components for your installation. This screen allows you to select some components to install with the main solution, such as Windchill PDMLink, and later install other components on a separate machine using the PSI’s option to install Standalone Products or Components.
The options for this step will vary depending on whether you are installing a monolithic or multi-tier system. If Java, the PTC HTTP Server, and Windchill Directory Server are installed already in their respective tiers, select Configure to an existing local installation. Otherwise, select Install and configure as the default for all options.
The following table describes each of the platform components:
Component
Description
Java SE Development Kit  (JDK)
The JDK provides a Java development and runtime environment for Windchill solutions.
PTC HTTP Server
The front-end authentication mechanism for your Windchill Web application. The PTC HTTP Server is bundled with Windchill solutions.
* 
If you plan to use a Web server other than PTC HTTP Server, PTC highly recommends that you install the bundled PTC HTTP Server to initially test your Windchill solution. After testing your solution with PTC HTTP Server, use the documented procedures to reconfigure your solution to use the other Web server. Testing your installation with PTC HTTP Server takes very little additional time up front and generally saves a great deal of time in troubleshooting if anything is not working properly with the other Web server.
Windchill Directory Server
Windchill Directory Server is an LDAP-compliant enterprise directory that is bundled with Windchill solutions.
An LDAP server is required for managing Windchill operation definitions. It can also optionally manage Windchill user information.
Database Software
• Install Pro/INTRALINK Oracle
Select the database you are using with your Windchill solution and click Next.
Oracle or SQL Server provides persistent data storage for Windchill solutions.
If you are installing bundled Pro/INTRALINK Oracle, select the Install Pro/INTRALINK Oracle check box.
If you are installing using the Oracle Real Application Cluster option, see Advanced Deployment Considerations for more information.
* 
Selecting either Oracle Advanced or SQL Server Advanced allows you to connect to your database using different database connection strings. For more information see Entering Your Database Information.
The following table lists the actions available in the drop-down list for the platform components:
Action
Description
Install and configure
Installs and configures this component on the local machine.
Configure to an existing local installation
Configures your Windchill solution to an existing local installation of the component.
Do not install or configure
Only select this option if you will install and configure the component at a later time. This option also is available if you can manually configure a remote component of that type. For example, select this option under servlet engine if you wish to manually connect to a remote servlet engine.
