JCL Setup

Copy the JCL member VMAJCL1 and make the following changes:

1. Add a job card.
2. Specify the HLQ parameter with a data set name high-level qualifier used to prefix the generated output data set name.
3. Check all marked statements for proper space parameter information. The VMA manual makes specific recommendations regarding these size specifications. Depending on how much data you process, this job can run for an hour or more, so it is important to provide enough space to avoid abends.
4. Specify the data set name and VOLSER information for all input SMF data you want to process.
5. Check the output data set specification to ensure it is valid and is on a volume where it can be saved for later processing.
6. Due to long processing times, confirm the TIME parameter on the JOB and STEP statement to ensure your job is not automatically terminated for lack of time.
7. You can specify VMA statements to limit collection of data to specific time periods, for example, for all the days in one month. Refer to the VMA documentation for details. Input parameters are not required, so the XTRCNTL DD statement may refer to an empty input list.
8. After your changes are complete, submit the job.
