Workload
analysis is used to determine system performance.
Statistics
should be checked, and trends should be recorded to get a “feel” for the
system’s behavior and performance. Understanding the system when it is running
well will help determine what changes need to be made when it is not.
1.
In the Command field, enter transaction ST03 and
choose Enter (or choose ToolsàAdministration, then MonitoràPerformance, then WorkloadàAnalysis).
2. To check Response times
A. Choose Detailed analysis menu from
toolbar.
B. Choose One recent period
from Performance history, Global.
C. Choose a time period.
Ø Today
Ø Previous days
Ø This week
Ø Previous weeks
Ø This month
Ø Previous months
D. Select date.
E. Choose Dialog at the
bottom of the screen
F. Choose Transaction profile
from the toolbar
Ø Main menu dialog step average
time should be very short
§ If it is not, this could indicate
a dialog instance bottleneck
Ø Key dialog transaction step time
components
§ Wait time should be very short
§ DB time should be much less than
CPU time
3. To compare servers
A. Choose Detailed analysis menu
from toolbar
B. Choose Compare all servers
from Performance history, Global.
Ø This indicates average
performance across all instances
Ø If there is a performance problem
specific to an instance, Avg wait time and CPU time will be the
best indicators.
