ADM100 Lesson: Setting up Operation Modes
Figure 40: Adjusting Instances to the Load Distribution
Using the operation modes, you can adjust the type and distribution of the
work processes to the varying load distribution during the day. You can
also adjust the distribution of the work processes to business requirements
that only occur once. By defining operation modes, you can change not
only the total number of work processes defined in the profiles, but also
thetypeanddistributionoftheindividualworkprocesstypeswithinthis
total number. The switch between the work process types is performed
dynamically during the runtime of the SAP system. The switch is triggered
using a defined schedule. A reserved work process is not immediately
terminated, but marked for switching. This means that certain delays may
occur. This type change is logged in the system log.
During the switch of the operation modes, neither the instance nor the
affected work processes need to be restarted. This means that the quality of
the buffer of the SAP system is retained during an operation mode switch,
and that the request that is currently being processed by a work process is
completed. The individual work processes retain their process ID after the
switch, which can be observed in the process overview (SM50).
