Table 1-1 Oracle WebCenter Installation Procedure

Task	Description	Mandatory or Optional?	Documentation
Task 1 - Prepare your system environment for installation	Ensure that your system environment meets the general installation requirements for Oracle Fusion Middleware, Oracle WebCenter, and Repository Creation Utility (RCU). Oracle WebCenter requires the availability of a supported database. Ensure that you have a supported database up and running.	Mandatory	For system requirements information, go to: http://www.oracle.com/technology/software/products/ias/files/fusion_requirements.htm For the latest information about supported databases, see the Oracle Fusion Middleware Supported System Configurations page on Oracle Technology Network at: http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html
Task 2 - Create WebCenter schemas	Use the RCU to create WebCenter schemas. Note: If you are using an IBM DB2 database, make sure you create the operating system users (one for each schema) before running the RCU.	Mandatory	In Oracle Fusion Middleware Repository Creation Utility User's Guide, refer to the following sections: See section "Oracle WebCenter Schemas" for information about WebCenter schemas that must be created depending on the WebCenter components you plan to install. See section "Creating Schemas" for information about how to create schemas.
Task 3 - Install Oracle WebLogic Server	Install Oracle WebLogic Server.	Mandatory	See the Oracle Fusion Middleware Certification Document to determine the exact version required for your installation: http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html See "Product Distribution" in Oracle Fusion Middleware Installation Guide for Oracle WebLogic Server for instructions on how to download the latest Oracle WebLogic Server. See "Running the Installation Program in Graphical Mode" in Oracle Fusion Middleware Installation Guide for Oracle WebLogic Server for installation instructions.
Task 4 - Install Oracle WebCenter	Use the WebCenter installer to install Oracle WebCenter. The installer lays down the binaries for all Oracle WebCenter products. Within the Middleware home directory, the installer creates the Oracle home directory (`Oracle_WC1` by default) and the Oracle Common home directory (`oracle_common`), as shown in Figure 1-1.	Mandatory	Chapter 2, "Installing Oracle WebCenter"
Task 5 - Configure Oracle WebCenter	Create a domain for Oracle WebCenter and choose the components you want to install. The Configuration Wizard creates the Domain home and Application home directories, along with the domain for the products you choose to configure. The Domain home and Application home directories can reside anywhere on your system. While creating your WebCenter domain, if you choose not to configure one or more WebCenter components, you can add them later by extending your WebCenter domain.	Mandatory	Chapter 3, "Configuring Oracle WebCenter"
Task 6 - Start the Administration Server and managed servers	To start Oracle WebCenter, you must first start the Administration Server. To start working with any Oracle WebCenter component, you must start the managed server to which that component is deployed. You can then access the component's URL and configure the component according to your requirements.	Mandatory	Section 3.2.1, "Starting the Servers"
Task 7 - Install and configure an external LDAP-based identity store	By default, Oracle WebCenter uses Oracle WebLogic Server's embedded LDAP identity store. For a production environment, you must reassociate Oracle WebCenter with an external LDAP-based authentication provider.	Mandatory for production environment	Section 3.3, "Setting Up an External LDAP-Based Identity Store"
Task 8 - Install and configure back-end components for WebCenter services	Developers and applications users can integrate WebCenter services into WebCenter applications. Certain services, such as Documents, rely on back-end components, such as Oracle Content Server. To provide for service integration into WebCenter applications, you must install and configure required back-end components. WebCenter Spaces provides several prebuilt workflows for Space membership notifications, Space subscription requests, and so on. To enable them, you must install and configure a Business Process Execution Language (BPEL) server.	Optional	Chapter 5, "Preparing Back-End Components for WebCenter Services"
