Reporting with a Tool You Already Own - DCOLLECT

Administrators and analysts are often called on to answer adhoc questions - how
much disk space do certain applications use? What's the utilization level of
some volume(s) or storage group(s)? Where are the backups for these datasets?
Collecting the necessary information from multiple different sources - disk and
tape volumes, DFSMS constructs, DFSMShsm data, can be a challenge. But there's
an often-underutilized resource already available in every data center that can
help - simple IDCAMS DCOLLECT control statements and a few REXX execs or
ICETOOL/SYNCTOOL jobs can provide quick, customizable reports on datasets,
volumes, and more. In this session we'll take a look at DCOLLECT - how it's
used, it's various types of output records, and how DCOLLECT output can be
filtered and formatted to produce useful information.
