Understanding the Uninstallation

The installation and upgrade processes do not automatically remove any JD Edwards EnterpriseOne databases. You should have a database administrator (DBA) for your relational database management system (RDMS) manually remove any unused databases according to the list of databases and associated components, which are provided in this document.

The uninstallation program restricts you from uninstalling a mandatory component without also removing all associated optional components that were previously installed. The relationship between the mandatory and optional components is shown in this table:

Server	Mandatory Component	Optional Components
Deployment Server	JD Edwards EnterpriseOne Files	Production Environment Prototype Environment Development Environment Pristine Environment
Enterprise Server	JD Edwards EnterpriseOne Foundation	ES Production ES Prototype ES Development ES Pristine
