Upgrading Third-Party or Other Deployment Components

Before beginning the infrastructure upgrade process, see System Requirements & Supported Platforms for Oracle Business Intelligence Enterprise Edition. Upgrading to Oracle Business Intelligence Infrastructure might require upgrading third-party or other deployment components, such as the Presentation Services servlet, database software, and ODBC drivers.

If an upgrade of a component is required, then that component upgrade must be performed before the Oracle BI Infrastructure upgrade is performed.

The components that must be upgraded depend on the version of Siebel Business Analytics that you are upgrading from and on the deployment environment. You must ensure that your system satisfies all of the requirements for the Oracle BI Infrastructure. The following are examples of some requirements:

• For all Microsoft Windows, Linux, and UNIX versions, JDK 1.5 or higher must be installed before you upgrade.
• On Windows 2003 SP1, the DEP settings must be changed before you upgrade.
• For Microsoft Windows systems that use the Microsoft Excel add-in, .Net Framework 2.0 must be installed before you upgrade.
• For Red Hat Linux, ensure that gcc files (C++ shared object files) are installed before you upgrade.
