History data set - Job Optimizer
You can use your existing SMF data as a starting point for choosing candidate jobs for Job Optimizer job performance processing. Job Optimizer uses the job structure and data access information that it collects during job analysis to optimize job performance processing.
Rather than waiting for jobs to accumulate sufficient historical information for job optimization, you can populate the History data set with SMF data from previously run jobs so that Job Optimizer can begin optimizing jobs immediately.
To populate the History data set with SMF data, your site must collect the following SMF record types:
- 14
- 15
- 17
- 18
- 30 (subtypes 1, 4, and 5)
- 61
- 63
- 64
- 65
- 66
- 67
- 68
- 101
Check your active SMFPRMxx member of PARMLIB to see what record types are being collected.
