Preface: SAP System Landscapes –
Basics!
•
When running business critical processes on an SAP production system, you have to customize
and develop on a separate SAP system, called the
development system
. Upon completion of
a change, the change needs to be transferred to a
•
quality assurance system
(also called
test system
), where the changes will be tested with
master data, ported from the
production system
. When it has been verified that the changes
function correctly, these changes will be ported from the development system to the production
system. Consequently, SAP recommends the implementation of at least three systems in every
SAP project.
•
On big systems, we recommend the additional installation of a
lab system
for testing new
software versions and operational concepts. Another critical task handled by the lab system is to
verify
if
backups from the production system can be restored
, implying that the
database size needs to be the same as that on the production system.
•
If your
production system
is deployed on a
cluster
, SAP
strongly recommends
the
installation of a
lab
system
which is also operated
in a cluster
.
•
HP recommends to provide high availability for production systems and to use a cluster generally
for 300 users and above.
