Data set naming standards
4 | Copyright © Interskill Learning Pty Ltd 2011 – Commercial in Confidence
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:•**.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.
Software Configuration Manager
•IBM SCLM and SCLM Advanced Edition• Runs on the Mainframe
• Holds all mainframe source code
• Controls all software compiles and migrations.
• Connected to Rational ClearCase.
• Access from SYSD. No access from SYSA or SYSB.
•Rational ClearCase• Runs on AIX Server AIX0001
• Holds all non-mainframe source code
• Connected to IBM SCLM
