TR3271 Management Programming Manual

PREFACE
In the Tandem environment, TR3271 provides application programs
with the ability to communicate with IBM hosts and IBM
3270-family devices. This manual provides subsystem-specific
information for application programmers using the management-
programming interfaces to manage the TR3271 subsystem. The
management-programming interfaces are based on the Subsystem
Programmatic Interface (SPI). This manual describes the control-
and-inquiry interface and the Event Management Service (EMS)
interface available to an application program for subsystem-
management purposes.
This manual is intended for application programmers in one of the
following categories:
• TAL, COBOL85, and C programmers who are writing management
applications that communicate with the TR3271 subsystem.
• TACL users who are writing macros and routines to perform
management functions on the TR3271 subsystem.
This manual serves as a reference manual for the development of
management applications. The seven sections and two appendixes
of this manual contain information as follows:
• Section 1 introduces the TR3271 subsystem and the objects
it controls. It also describes the required management
functions, the relationship of the subsystem to other
subsystems, and the architecture of the TR3271 subsystem.
• Section 2 describes management programming. This section
describes the purpose of management programming and how
applications fit into the Distributed Systems Management
(DSM) architecture. It also contains tables of TR3271
programmatic commands and a comparison of programmatic and
operator commands.
• Section 3 describes the elements of SPI messages.
