Using Data Facility Storage Management Subsystem (DFSMS)

This topic gives you a brief overview of DFSMS, and explains ISMF applications.

ISMF has a number of applications that the storage administrator uses to automate and simplify storage and data management tasks. These applications form DFSMS and provide a user interface to many DFSMSdfp, DFSMShsm, DFSMSdss, DFSMSrmm, and ICKDSF functions.

The ISMF applications include:

Aggregate Group
Automatic Class Selection
Control Data Set
Data Class
Data Collection
Library Management
Management Class
Storage Class
Storage Group

As an end user, you have access to information about the Data Class, Management Class, Storage Class and Aggregate Group applications of DFSMS. The other DFSMS applications are available only to your storage administrator, and therefore they are not discussed in this manual. For more information about these other applications refer to z/OS DFSMSdfp Storage Administration.
