Glossary
This glossary defines the terms used in this manual and related terms.
ABEND. (1) An abnormal end of a task or process. (2) An error condition that can result in
the termination of a program.
ABORT. A sensitive SCF command that terminates the operation of an object as quickly as
possible; only enough processing is done to ensure subsystem security.
ADD. A sensitive SCF command that adds an object to the PAM subsystem.
aggregate SDU. A grouping of multiple SDUs into one request or response.
ALTER. A sensitive 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.
AppleTalk Address Resolution Protocol (AARP). A protocol that reconciles addressing
differences between the Ethernet Data Link protocol and the addressing scheme used by
the AppleTalk protocols, facilitating the transport of Datagram Delivery Protocol (DDP)
packets over an EtherTalk network. The AARP module also uses the ServerNet LAN
systems access (SLSA) interface (Data Link Layer) to access an Ethernet LAN.
ASCII. American National Standard Code for Information Interchange. (1) A method of
coding data, consisting of 7 bits for each character plus a parity bit. Designed for
asynchronous or byte-synchronous use, the code has 128 standard characters. (2) An 8-
bit code representing characters and control codes. One of two major codes used to
represent and exchange data (the other is EBCDIC).
attribute. In DSM, a characteristic of an entity. For example, two attributes of a SLSA
communications line might be its DFT and its RETRYLIMIT. In a token-oriented
interface based on the Subsystem Programmatic Interface (SPI), an attribute of an object
is usually expressed as either a simple token or a field within an extensible structured
token.
command file. A text file containing a series of commands that the user can run by issuing
the OBEY command in TACL or Subsystem Control Facility (SCF), followed by the
name of the text file.
CONFTEXT. The main configuration file that contains all the hardware descriptions
applicable to your Tandem system.
CONNECTION object. Represents a link between local and remote NETNAM line
handlers.
