Programmatic Interface to DSM/TC Functions

Management application control of the DSM/TC subsystem takes place by using

Subsystem Programmatic Interface (SPI) procedures to communicate with the

DSM/TC programmatic process, MEDIASRV. The application uses the SPI procedures

to compose SPI command messages for the MEDIASRV process and to interpret the

responses received from the MEDIASRV process. MEDIASRV is the interface between

the management application and the other elements that make up the DSM/TC

subsystem.

Application Management Functions

To manage the various aspects of the DSM/TC subsystem, use commands supported

by the MEDIASRV programmatic interface. These commands are similar to those

issued through the interactive interface MEDIACOM. Use them to:

•

Define subsystem elements

•

Implement a new configuration

•

Start and stop the subsystem

•

Start and stop transaction processing

•

Display the status of DSM/TC objects

•

Control specific transactions

•

Implement changes in a configuration
