Loaders

A loader is a tool for introducing new or modified system components, programs, or data to a TPF system. All loaders have both an online and offline component.

Offline Component
Takes system components, programs, or data from the MVS data sets and writes them to a storage medium such as tape, DASD, virtual reader, or user-defined device.

Online Component
Takes the system components, programs, or data from the storage medium and loads them to their proper location on the online system.

The load functions of a TPF system are handled by the general file loader, data loader, E-type loader, and auxiliary loader. Only the general file loader is used for an initial full load (see Loading System Components to a New TPF System).

Once you complete a full load, you do not need to do another except for some DASD configuration or core image restart (CIMR) changes.
