Open Enterprise Server (OES) 2015 SP1 includes enhanced and updated services for Linux that were traditionally only on NetWare.
Managing the services after they are installed is very similar to managing them on NetWare. On the other hand, installing them is quite different.
Micro Focus recommends that you install SUSE Linux Enterprise Server (SLES) and OES at the same time, and also patch SLES and OES at the same time. Update the system with all of the SLES 11 SP4 patches as documented in the “YaST Online Update” section in the SUSE Linux Enterprise Server 11 SP4 Administration Guide.
If you install OES after you install SLES, Micro Focus recommends that you patch both SLES and OES before you start the OES configuration.
