SNAX/HLS Management Programming Manual

2 Management Programming for
SNAX/HLS
104708 Tandem Computers Incorporated 2–1
The management programming interfaces to the SNAX/HLS subsystem enable
applications to execute configuration commands programmatically and to obtain
configuration and statistical information about SNAX/HLS.
Relationship of
Applications to the
SNAX/HLS Subsystem
Management programming applications do not communicate directly with the
SNAX/HLS subsystem. Instead, an application typically sends a request to the
Subsystem Control Point (SCP), which examines the request, determines its
destination data communications subsystem (in this case, SNAX/HLS), and sends it to
the indicated subsystem.
When the SNAX/HLS subsystem finishes processing a request, it returns the response
to the SCP, which then forwards the response back to the application.
Introduction to
SNAX/HLS
Programmatic
Interface Commands
This subsection briefly describes the programmatic interface commands available for
use with the SNAX/HLS subsystem.
The SNAX/HLS programmatic interface commands and the object types that apply
are shown in Table 2–1.
Table 2–1. SNAX/HLS Programmatic Interface Commands
Commands Object Types

SNAX/HLS controls the security of commands. Security is applied only to the
ABORT SESSION and SWITCH PROCESS commands. For further information on
security, see Section 5, “SPI Programming Considerations for SNAX/HLS.”
The SNAX/HLS commands are described in detail in Section 7, “Commands and
Responses.”
