Figure 6-1 shows three unrelated applications—App1, App2, and
App3—sharing a server without the benefit of duration management.
The applications most critical to the business, App1 and App2, run
continuously and tend to consume about 20% and 50% of the CPU
resources, respectively. The CPU-intensive App3 is started once a day
and runs for about two hours, using about 60% of the CPU resources and
finishing about 6 am. Unfortunately, it also greatly reduces the CPU
resources that App1 and App2 receive. These other applications quickly
recover once App3 finishes, though.
