Figure 39: Concept of Operation Modes
The type and number of work processes for each instance is defined in the
profiles. The distribution of work processes in the profiles is optimized
for fast dialog response times; that is, there are usually lots of dialog work
processes and a small number of background work processes. This means
that during the night, system resources, such as the main memory, are tied
to the dialog work processes, or are not fully utilized by the background
processes, such as the CPU. It is therefore practical to define different types
and numbers of work processes for these different demands on the SAP
system. This is realized through the concept of operation modes.
