SMFVIEW by ASPG is a tool for examining and repairing critical SMF data, essential for daily operations. It operates as an ISPF based full-screen browser and editor for any SMF data source. Using the powerful filtering and data selection capabilities of SMFUTIL, SMFVIEW allows quick access to selected SMF data. Input sources may be SMFUTIL archive files, current SMF MANx files, or a user-specified sequential SMF dataset. Record selection is by type, subtype, date, and time. Filtering criteria include SMF system ID, jobname, userid, account code, dataset name, and volume serial. Masking is supported for each filter. A scrollable full-screen display of each selected record is available. The SMFVIEW display mode is a DUMP mode showing a hexadecimal dump and EBCDIC translation of the record. Each line on the display shows the hex and decimal offset into the record, starting with the record descriptor word (RDW). This mode enables data content alteration at the hex or character level. SMFVIEW provides quick and easy access to selected SMF data, saving time and CPU resources, leading to cost savings. It allows developers to quickly access and review specific record types under development or scan archives for particular dataset names. SMFVIEW brings the speed and agility of the SMFUTIL product to the TSO screen in a unique and functional way. It allows users to select specific record types and subtypes or exclude certain rectypes, as well as additional filtering criteria.
