SNAX Creator
SNAX Creator. Compaq software that supports SNAX/XF and SNAX/CDF by creating new
application processes. Creator enables the creation of a Compaq process when a terminal
on an IBM subarea network sends a logon request to the application. Creator does not
support SNAX/APN.
SNAX Creator-2. Compaq software that supports SNAX/APN and SNAX/XF by creating
new application processes. Creator-2 enables the creation of a Compaq process when a
terminal on an IBM subarea network sends a logon request to the application. The
differences between Creator and Creator-2 are that Creator-2 has more functionality, can
be configured using SCF, provides load-balancing capabilities, and does not support
SNAX/CDF.
SNAX over Ethernet. A feature of the SNAX/APN-EN (End Node) product that provides an
interface to the NSK LAN Server and enables SNA communication over an Ethernet
LAN. This feature is not offered with the basic SNAX/APN (LEN Node) product.
SNAX/XF. A Compaq software product that provides a gateway between Compaq
NonStop™ systems and SNA systems and devices. SNAX/XF uses subarea networking
to communicate with directly attached SNA devices and directly attached SNA hosts,
and to function as fully integrated components of an hierarchical SNA network. The
Compaq system functions either as a type 5.0 node (without cross-domain functions) or
as a type 2.0 node. These functions can be combined to allow transparent pass-through
of data flows between SNA devices in a Compaq network and SNA hosts. SNAX/XF
provides device control, session passthrough, and application-to-application
communication.
SPI. See Subsystem Programmatic Interface (SPI)
.
SPI buffer. The buffer that contains an SPI message. See also SPI message
.
SPI common extensions standard definitions. The set of declarations provided by Compaq
for use in all management programs that manage, or retrieve event messages from, many
Compaq subsystems. The names of these definitions start with ZCOM-, ZCDG-, or
ZCMK-. See also definition files
.
SPI message. A message specially formatted by the SPI procedures for communication
between a management application and a subsystem, or between one subsystem and
another. The message consists of a collection of tokens. Note that an SPI message is a
single block of information sent at one time as one interprocess message. There are two
types of SPI messages, distinguished by different sets of tokens in the header: command
and response messages, and event messages.
SPI procedures. The set of Guardian procedures used to build and decode buffers for use in
system and network management and in certain other applications. These procedures are
SSINIT, SSNULL, SSPUT, SSPUTTKN, SSGET, SSGETTKN, SSMOVE, and
SSMOVETKN.
SPI standard definitions. The set of declarations available for use with the SPI procedures.
There is also a set of subsystem-specific declarations for each subsystem (the tokens
defined for SNAX/XF start with ZSX1-), and some sets of declarations that apply to
