The figures below show the Resource Component Analysis Reports for this case study. As this report shows, the DATABASE and ONLINE workloads are the largest contributors to the overall processor usage. The next most relevant workloads are BATCH and TSO. Of these, TSO is interesting in that while it ranks fourth in terms of relative importance, its average CPU usage value is rather small, less than 18 minutes per week. Other workloads that are much higher in CPU usage rank less, perhaps indicating a relationship between the TSO workload and others, the DATABASE workload being the likely candidate. The analyst should do additional research regarding this result to better understand the overall affect TSO may have on the capacity planning effort.

Figure 13-2.03 Resource Component Analysis Report - first execution For a second execution, only the DATABASE, ONLINE, BATCH and TSO workloads are used. The report produced is shown next. Notice that the Importance weight values have changed as one would expect, but that the weight for the TSO workload has increased, indicating a stronger relationship with the other workloads. Again, additional analysis may be indicated before making any final conclusions regarding the workloads and their makeup.
