DFSMSdfp™ provides several types of tools for system programmers and database administrators to use to manage the organization and storage of data in the z/OS® environment.

With DFSMS™ tools, you can use access methods with macro instructions to organize and process a data set or object; use access method services commands to manage data sets, volumes, and catalogs; use utilities to perform tasks such as copying or moving data. You also can use system commands to display and set SMS configuration parameters, callable services to write advanced application programs, and installation exits to customize DFSMS.
