Help with Running the Sub-Capacity Reporting Tool (SCRT) and Interpreting the SCRT Report

The SCRT User Guide (PDF,2.77MB) should be your first point of reference for all questions about configuring your system for sub-capacity, tailoring the SCRT JCL, running the SCRT program, and interpreting the SCRT Reports.

If you have questions about how SCRT calculates the MSUs it reports for a program or questions about how Defined Capacity and Group Capacity can be used to help control your sub-capacity software charges, we offer two downloadable educational modules on the Reference Library web page.

If you have questions about how your SCRT Reports may be affected by moving LPARs between machines, moving workloads between LPARs, or moving programs, please see the Sub-Capacity Corner Terms web page.

If you have questions about the process to follow when you have machine upgrades or machine consolidations, please see the Sub-Capacity Corner Procedures web page.

For further help about running the SCRT program or the SCRT89RU program or further help interpreting the SCRT Report, please contact IBM via email. Please be sure to include all of the following information in any correspondence with the SCRT Support Team:

The SCRT Support Team maintains business hours of 9:00am to 5:00pm US Eastern Time, Monday through Friday. We will normally respond to your question/problem within two business days, however, some complex issues may require more time to research.
