IAMSMF Overview

Overview

The IAM product includes a specialized SMF reporting program called IAMSMF. This program is intended to aid customers in converting VSAM data sets to IAM and in using IAM data sets in their installation. Customers can use IAMSMF to:

  1. Aid in conversion of data sets from VSAM to IAM, by providing the capability to determine what jobs and job steps are defining the VSAM data sets, as well as processing the selected data sets.
  2. Provide reports on SMF job statistics to help evaluate the benefit of IAM. You can obtain reports that include CPU time, EXCPs, and elapsed time for jobs using VSAM data sets. Then, compare the jobs based on those statistics to see the improvements realized after converting the VSAM data sets to IAM.
  3. Provide detailed reports on IAM data set activity by producing the IAMINFO reports from the IAM SMF records.
  4. Find what jobs or users are accessing data sets.
  5. Print or copy selected SMF records.

Functional Summary

The IAMSMF program has been designed to give users the ability to extract data and statistics from Systems Management Facility (SMF) records. The functions include data set query, printing IAMINFO reports, job reporting, record copy, and record print. IAMSMF is a batch program, which based upon simple control statements, will extract resource utilization information from SMF job/step and data set records. Information can be selected directly from the active system SMF data sets, from SMF format archival files, or from extract files created by the COPY function of the program itself.

Command Summary

IAMSMF has the following commands:

  • COPY: Copy selected SMF records to a sequential file creating a subset of the data for later use.
  • IAMINFO: Produce IAMINFO reports from IAM generated SMF records.
  • PRINT: Print selected SMF records in dump (Hexadecimal) format.
  • QUERY: Produces a data set oriented report, to find out what job steps use the specified data sets, and how they are used. It can be requested for specific data set names or by data set name prefixes (data set groups).
  • REPORT: Produces a job oriented report, with a break out or resource and data set utilization by job step. The report is produced in chronological order from the available SMF data. Can be requested for a specific Jobnames or by Job Group Names.
Error
Warning

The REPORT process is provided on an as-is basis. The use of the reports generated by the IAMSMF REPORT process are intended for general informational purposes provided to help evaluate the IAM product. The results are not certified to meet with all of the complexities involved in processing SMF data which are beyond the scope of the intentions of this program.
