Input from system management facility (SMF) data on new allocations can be used to create test cases. This SMF input data is created by using the storage class ACS exit code available in the sample library SYS1.SACBCNTL. Once the exit is installed and a SMS minimal or null configuration is running, all new allocations are captured and written to SMF. A program (ACSTST) for postprocessing of the SMF data, which NaviQuest uses to generate standard SMS test cases, is also included.

Restriction: Use the SMF data created out of the IGDACSSC exit in selected situations. For example, the extensive testing of system temporary data sets.
