Chapter 3. Operating NetView FTP V2.2.1 MVS - IBM

where the interruption occurred instead of from the
beginning of the file.
checkpoint file. A synonym for checkpoint data set.
checkpoint record. A record of a checkpoint data set
or file. One checkpoint record contains the information
needed to restart one file transfer from a checkpoint.
checkpoint/restart data set. A deprecated term for
checkpoint data set.
checkpoint/restart record. A deprecated term for
checkpoint record.
class. See server class.
client. On a local area network, a workstation that
requests service from a server workstation.
CLIST. Command list.
Coded character set identifier. In NetView FTP, an
identifier that represents a set of graphic characters and
their code point assignment. The coded character set
identifier defines how characters are mapped to decimal
values.
command control block. A control block that contains
details of the queue handler command to be carried out.
command list. A list of commands and control statements
that is assigned a name. When the name is
invoked (as a command) the commands in the list are
executed.
common service area. In MVS, a part of the common
area that contains data areas that are addressable by
all address spaces. During use, these areas are protected
by the key of the requester.
completion user exit. Deprecated term for posttransfer
user exit.
compression. A technique for converting data into a
form that requires less storage space and less transmission
time than its original form. Contrast with
decompression. See also SNA compaction and SNA
compression.
condition code. A 4-digit decimal value derived from
the value a server places in register 15 before returning
control to the operating system. The digits of the condition
code consist of the server return code and, for a
server running in single mode, the file-transfer return
code.
continuous mode. A server running mode in which a
server continues running after it has transferred a file.
control language. The set of all commands with
which a user requests system functions.
control point. A component of an APPN or LEN node
that manages the resources of that node. In an APPN
node, the CP is capable of engaging in CP-CP sessions
with other APPN nodes. In an APPN network node, the
CP also provides services to adjacent end nodes in the
APPN network.
control statement. A statement that controls or affects
the running of a program. For example,
NOTAFTER=(‘21:34’,‘94/12/25’) is a control statement
that assigns the value (‘21:34’,‘94/12/25’) to the parameter
represented by the keyword NOTAFTER.
conversation. In SNA, a connection between two
transaction programs over an LU-LU session that lets
them communicate with each other while processing a
transaction.
CP. Control point.
CP-CP sessions. The parallel sessions between two
control points, using LU 6.2 protocols.
Cross-domain resource. In VTAM programs,
synonym for other-domain resource.
Cross-domain resource manager. The functions of
the system services control point (SSCP) that control
initiation and termination of cross-domain resources.
cryptographic key. A value used to encrypt and
decrypt data transmitted in an LU-LU session that uses
cryptography.
cryptography. The transformation of data to conceal
its meaning.
CSA. Common service area.
current request. The request currently being created
or changed by the user of the NetView FTP panels.
daemon. In the AIX operating system, a program that
runs unattended to perform a standard service.
daemon process. In the AIX operating system, a
process begun by the root user or the root shell that
can be stopped only by the root user. Daemon processes
generally provide services that must be available
at all times.
DASD. Direct-access storage device.
data control block parameters. The following parameters:
Record Format, Logical Record Length, and
Physical Block Size.
