FDRARC is a high-performance data migration and space management tool that can be used to control the consumption of your z/OS disk storage. With FDRARC, unwanted and expired data sets can be quickly and efficiently migrated to a less expensive medium, such as a high-capacity tape, a VTS, or to a compressed format on another disk.
Migrated data sets are recorded in a control file and recataloged to a volser of MIGRAT. FDRARC's auto-recall facility ensures that a migrated data set can be easily and transparently recalled to disk if it is referenced by a batch job, online application, or an end-user.
FDRARC is incredibly easy to use and it can be installed and operational in less than 1 hour. It can be used on a single volume, a pool of volumes, or your entire DASD subsystem.
When operating in a DFSMS environment, FDRARC can utilize the “space management” criteria set in the DFSMS Management Class for each data set on each volume processed. Thresholds can be established on volumes so that FDRARC space management can be invoked to maintain a certain level of free space within the DASD storage pool.
FDRARC can also be used in non-DFSMS environments, such as development or testing systems, where user data often goes unused for long periods of time.
Archive Simulation with FDRQUERY
FDRARC includes a report utility called FDRQUERY, which can be used to illustrate the effects of a data migration policy against one or more disk volumes using a range of “not-referenced” criteria.
