pass-through error
pass-through error. An error originally reported by one subsystem or system component
but included in a response record produced by another subsystem. Typically, a
subsystem passes an error from a second subsystem only if that error prevented the
first subsystem from performing a command successfully. A pass-through error is
expressed as an error list that is nested within another error list. See nested error list
.
position descriptor. A four-word block of information that indicates a position within an SPI
buffer. A position descriptor is used as a parameter to some of the special operations
for SSGET and SSPUT.
positioning operation. An operation that gets, sets, or changes the current position in an
SPI buffer, or that creates in the buffer a construct (like a list) that provides a scope for
retrieval of data.
predefined value. A commonly used value that is given a symbolic name in an SPI
definition file.
private token type. A token type defined by, and specific to, a particular subsystem. A
private token type is built from standard SPI token data types, although it might have
additional semantic connotations for the subsystem. For example, a subsystem might
define a token type that looks to SPI like an integer but that implies to the subsystem a
range of values smaller than an integer type would allow. See token type
.
procedural interface. A means for obtaining services through procedure calls; also, the set
of procedures through which services are obtained. For instance, an application has a
procedural interface to SPI; that interface consists of the procedures SSINIT, SSNULL,
SSPUT, SSPUTTKN, SSGET, SSGETTKN, SSMOVE, and SSMOVETKN.
programmatic command. A command issued by a program, rather than by a human
operator.
programmatic interface. A means for a program to communicate with another program.
On an HP NonStop system, a programmatic interface typically includes: a message
format, a set of message formats, or a set of procedures (such as the SPI procedures)
to build and decode messages; definitions of message elements (commands, data
types, objects, parameters, response data, errors, and so on); rules for communication
between the requester and the server; and software to receive and respond to
messages defined for the interface.
programmed operator. A management application that performs functions that might
otherwise be performed by a human operator.
qualified token code. A token code that includes a subsystem ID.
requester. An SPI requester. A management application that sends SPI commands to a
subsystem server.
