I have also used response time goals for batch work, but only for batch that should be short running (short test jobs) and where there would be a relatively large number of jobs in a given time period. Then I have a second period to drop the work into and give that a velocity goal if it goes past the desired turnaround time. In doing have used that to penalize programmers who submit jobs to my "short job" (30 minutes or less) job class that will end up running for hours. My thoughts on needing a large number of jobs going through are that if you don't have enough work then WLM won't get enough samples to calculate a valid response time. Am I thinking correctly here? Also, using discretionary work where a system is constrained could be good if you are sure the work is discretionary. It will get the hind most when WLM is given out resources, but that way your truly important work will get the resources. However, as I said earlier, without SLAs or some internal goals how do you know what is important. ***************************************************************************** If you wish to communicate securely with Commerce Bank and its affiliates, you must log into your account under Online Services at http://www.commercebank.com or use the Commerce Bank Secure Email Message Center at https://securemail.commercebank.com NOTICE: This electronic mail message and any attached files are confidential.
