Rerunning the Platform Pack Installer

You must rerun the JD Edwards EnterpriseOne Platform Pack Installer to support these scenarios:

• You want to install the Enterprise Server and the Database Server on physically different machines.

• You want to add an Enterprise Server environment to the Enterprise Server.

• You want to add a Database Server database to the Database Server.

• You want to reinstall the JD Edwards EnterpriseOne Foundation on the Enterprise Server.

• You want to reinstall the System Database on the Database Server.

You should never reinstall any optional components without first deinstalling the components. If you select to deinstall the mandatory components you must also select to deinstall or have already deinstalled all related optional components. This table lists the mandatory and related optional components:

Server	Mandatory Component	Optional Components
