5. Data set allocation standards 5 |Copyright © Interskill Learning Pty Ltd 2011 – Commercial in Confidence z/OS Class Selection Routines Automatically Fill in the Blanks. Do Not Set the VOLSER Use your own DCB attributes if needed. No limit on space, but be frugal. Special Attributes DATACLAS = VSAMRLS – VSAM Record Level Sharing UNIT=VIO – in-memory dataset for temporary datasets < 1 cylinder UNIT=TAPE – tape datasets. MGMTCLAS = DELIN1 – delete this dataset in one year from when it was last updated.
