To install DSfW, you need a server that meets the system requirements for Open Enterprise Server. For more information, see Installing OES 2018 SP2 as a New Installation
in the OES 2018 SP2: Installation Guide.
You should have access to the installation media for OES, either on physical CD/DVD media or on a networked installation source server. For more information about installing OES from an installation source, see Setting Up a Network Installation Source
in the OES 2018 SP2: Installation Guide
NOTE:Ensure that only root account is created during the SLES installation because administrator or other Active Directory account names can conflict with the DSfW users.
