control and inquiry
subsystem sends a response message that does not contain a context token, the
series of response messages is complete.
control and inquiry. In DSM, those aspects of object management that affect the state or
configuration of an object, such as inquiries about the object and commands pertaining
to the environment (for example, commands that set default values for the session).
Compare event management.
critical event. A DSM event that is considered to be crucial to the operation of the system
or network. Each subsystem determines which of its events are critical, designating
them as such by setting the value of the emphasis token to TRUE. Compare noncritical
event.
CSMA. See Carrier Sense Multiple Access (CSMA).
CSMA/CD. See Carrier Sense Multiple Access with Collision Detection (CSMA/CD).
DARPA. See Defense Advanced Projects Research Agency (DARPA).
data communications standard definitions. In DSM, the set of declarations provided by
HP for use in all management programs that manage or retrieve event messages from
NonStop data communications subsystems. The names of these definitions start with
either ZCOM or ZCMK. See also definition or definition files. Compare SPI standard
definitions or EMS standard definitions.
data list. In DSM programmatic interfaces, a group of tokens used to separate response
records within an SPI message for a response, or used to enclose a single response
record, if the program so requests. A data list consists of a list token that denotes a
data list (different from the token that starts an error list or a generic list), followed by a
response record and an end-list token. See also response record.
DDN. See Defense Data Network (DDN).
Defense Advanced Projects Research Agency (DARPA). Formerly called ARPA. The
government agency that funded research and experimentation with the ARPANET and
DARPA Internet.
Defense Data Network (DDN). Used to loosely refer to the MILNET, ARPANET, and the
TCP/IP protocols they use. More literally, it is the MILNET and associated parts of the
Internet that connect military installations.
definition. One of the declarations provided by HP for use in applications that call APS or
SPI procedures. These definitions are provided in definition files. See also definition
files.
definition files. A set of files containing declarations for use in applications that call SPI
procedures. SPI has a standard definition file for the Data Definition Language (DDL)
and one for each of the programming languages supporting SPI; the latter files are
derived from the DDL definition file. Likewise, each subsystem that has a token-
