HP-UX WLM Duration Management Toolkit and HP-UX WLM Toolkit for Base SAS Software
Overview of how WLM’s duration management works
Chapter 6 109
Figure 6-3 Overview of how applications can be managed
Figure 6-4 shows how duration management works in environments
with SAS. It is the same situation as in Figure 6-3 except that you can
instrument the SAS jobs. You instrument a SAS job with the macro
hp_wlmtk_goals_report to fine-tune duration management. This
fine-tuning is desirable when there are fluctuations in data set size. For
example, the macro can inform wlmdurdc when the job is 25% complete,
despite the fact that the time to complete 25% of the job changes as the
size of the data set changes.
