Data from up to sixteen different SYSIDs can be processed by CRURRSV. If for some reason the user has SMF data from more than sixteen systems merged together, even though fewer than sixteen systems could have updated the catalog being recovered, then the data for just the systems that could have updated the catalog should be extracted (using IFASMFDP or another utility) before the data is passed to CRURRSV. If more than sixteen systems could have updated the catalog (due to intermittent use of test systems, for example), use IFASMFDP (SMF dump) or another utility to create more than one data set, each of which has sixteen or fewer SYSIDs represented. Run each batch through CRURRSV separately, then concatenate the outputs from the CRURRSV runs as input to the sort.
