Data set naming standards
High Level Qualifiers:
•User Datasets: uid.**
(e.g. U10153.MISC.CNTL)
•Group Datasets: ghlq.**
(e.g. APPGRP1.SRC.CNTL)
•Production Datasets: prod.**
(e.g. PROD.JCL)
•System Datasets: sys%.**
(e.g. SYS1.LINKLIB)
Low Level Qualifiers:
4
|
•**.CNTL or **.JCL – JCL libraries
(e.g. U10153.MISC.CNTL)
•**.SRC – Program Source
(e.g. U10153.SRC)
•**.H – C includes
(e.g. U10153.H)
•**.TEXT – text libraries
(e.g. PROD.BATCH.TEXT)
•**.LOAD – load libraries
(e.g. PROD.IMS.LOAD)
•**.OBJ – object libraries
(e.g. PROC.CICS.OBJ)
•**.PROCLIB – procedure libraries.
(e.g. PROD.PROCLIB)

Data set allocation standards
• 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.
