DFSMSdss

The architecture of DFSMSdss is centered around several key components that work together to provide robust data management capabilities. The DFSMSdss address space is the primary execution environment for the utility. The data mover component handles the actual data transfer operations during backup, restore, and copy processes.

Control blocks manage the internal state and operation of DFSMSdss, coordinating various tasks. The catalog interface facilitates interaction with the z/OS system catalog, enabling the location and management of datasets. Communication between these components is primarily internal, using z/OS system services and control blocks.

Data is stored on DASD (Direct Access Storage Devices) and managed through the z/OS file system. DFSMSdss does not have specific network port requirements, as it operates within the z/OS environment. Security is integrated through RACF, which controls access to datasets and volumes.

Data encryption is supported during backup and restore operations. Auditing capabilities are provided through system logs, which record details of operations for security monitoring and compliance. DFSMSdss is a core utility for z/OS data management, offering essential backup and recovery capabilities.
