Glossary
This glossary defines terms used and referred to in this manual. For abbreviations of
terms specific to SNAX and HP NonStop products, the definition consists of a cross-
reference to the spelled-out term.
In addition, several definitions have been borrowed from the IBM Dictionary of
Computing and the IBM Network Program Products: General Information manual.
ABORTING state. As defined by SCF or SPI, the state of an object when an ABORT
command has been issued against that object but has not completed. This state
indicates that sessions and data traffic are being interrupted abnormally, with possible
loss of data.
ACTIVE state. An SNA object state indicating that the object is able to perform the function
for which it was designed.
ADAPTER object. An SCF object defining a SWAN concentrator.
ADD command. A sensitive Subsystem Control Facility (SCF) command that defines an
object to a subsystem.
advanced peer-to-peer networking (APPN). Networking in which all nodes communicate
as peer type 2.1 nodes. An extension of SNA featuring greater distributed network
control that avoids critical hierarchical dependencies, thereby isolating the effects of
single points of failure. APPN extends the LU 6.2 peer orientation for end-user services
to network control. Implemented (at the entry level) in the SNAX/APN product. Contrast
with subarea networking.
advanced program-to-program communication (APPC). An implementation of the SNA
LU 6.2 protocol that allows program-to-program communication among interconnected
systems. Implemented in the SNAX/APC product.
alias LU name. A temporary LU name used by SNAX/CM that is generated by SNAX/XF.
The alias LU name is the first LU name of the LUs configured under the connected PU.
A portion of the alias LU name and the alias LU count can be used to construct all the
alias LU names for a connected PU.
alphanumeric. A parameter definition indicating that a valid character can be alphabetic (A
through Z, upper case or lower case) or numeric (0 through 9).
ALTER command. A sensitive Subsystem Control Facility (SCF) command that changes
the values of the attributes of an existing object. This command changes only the
specified attributes of the named (or assumed) object or objects.
alternate path. A path not enabled as the preferred path. An alternate path can become a
primary path when a primary path is disabled. Contrast with primary path
.
