You can collect information
on active and inactive data set space
utilization and capacity planning by using the ISMF Data Collection
application to produce a DCOLLECT job. DCOLLECT provides measurement
data in a sequential data set (also called a flat file), which can
be used as input to the DFSMSrmm Report Generator
for creating customized reports and to other applications such
as billing and report formatting.
You can use it to produce
measurement data on: active data sets,
which are data sets that have not been backed up or migrated; inactive
data sets, which are data sets that
have been
backed up or migrated; capacity planning, which concerns volume capacity
and usage; and volumes. Information can be obtained on the following:
- Active data sets
- Volumes
- Migrated
data sets (DFSMShsm)
- Backup data sets (DFSMShsm)
- DASD
capacity planning (DFSMShsm)
- Tape capacity planning (DFSMShsm)
DCOLLECT is an access method services function.
