What is the primary function of FDRARC?
FDRARC automates the archiving of datasets to less expensive storage, such as tape or Virtual Tape System (VTS). It manages the migration of datasets based on administrator-defined criteria like age and size. Datasets are automatically recalled when accessed.
How does FDRARC determine which datasets to archive?
Administrators define policies that specify which datasets to archive. These policies use criteria such as dataset age, size, and last-used date. The system then automatically migrates datasets matching these criteria.
How does FDRARC handle dataset recall?
When a user or application attempts to access an archived dataset, FDRARC automatically recalls it from the archive storage. The recall process is transparent to the user, who accesses the dataset as if it were still on disk.
What is the purpose of the FDRQUERY tool?
FDRQUERY is a utility provided with FDRARC. It allows administrators to simulate the effects of different migration criteria without actually archiving any data. This helps in fine-tuning archive policies.
