Interface Types

Functions of the automated tape library interface may be implemented in either of the following ways:

• Through an interface supplied with Control-M/Tape
  • This type of interface usually consists of a automated tape library interface module that accesses the automated tape library database through an automated tape library API.
  • Automated tape library exits are also supplied with Control-M/Tape. These exits enable Control-M/Tape to obtain control of tape processing at certain key points (for example, volume ejection).

  The interface module and sample exits can be customized to reflect the needs of your site.

• Through an interface supplied with the automated tape library

  This type of interface usually consists of a batch utility that is added to the Control-M/Tape New Day procedure. This utility reads the Media Database through a Control-M/Tape API and updates volume status in the automated tape library database accordingly.

  Many vendor-provided interfaces automatically recognize Control-M/Tape mount and keep messages (for example, CTT101A and CT102A).

This chapter describes the automated tape library interfaces provided with Control-M/Tape. For information about the interfaces provided by an automated tape library vendor, see the relevant documentation.
