connection
connection. (1) The path between two protocol modules that provides reliable stream
delivery service. (2) For the Compaq TSM package, the logical link established
between the TSM client software on a workstation and the TSM server software on an
HP NonStop™ S-series system after a logon sequence has been performed. There are
two types of logical connections: service connections and low-level links.
Connection view. One of several views of a server available in the view pane of the
Management window of the Compaq TSM package. The Connection view is a visual
representation of the connectivity among components within an enclosure. See also
Physical view.
connectivity. The ability of a system to transfer information between itself and a system
from another vendor. Other vendors use the term “connectivity” to mean hardware
compatibility. See also interoperability.
connector. See port.
console message. See operator message.
contiguous ground. An insulated grounding conductor that extends from an equipment
enclosure power receptacle to the final point of electrical service for the computer-room
equipment, whether that final point is the main service entrance or the separately
derived power source. In most instances, the final point of electrical service is an
isolating transformer installed in the computer room.
control and inquiry. Those aspects of Subsystem Control Facility (SCF) object
management related to the state or configuration of an object. Such aspects include
actions that affect the state or configuration of an object, inquiries about the object, and
commands pertaining to the session environment (for example, commands that set
default values for the session).
controller. See I/O controller or ServerNet addressable controller (SAC).
controlling process. In the Open System Services (OSS) environment, the session leader
that established the connection to the controlling terminal. The session leader stops
being the controlling process when the corresponding terminal stops being the
controlling terminal.
controlling terminal. In the Open System Services (OSS) environment, a terminal that
might be associated with a session. A session can have only one controlling terminal,
and a controlling terminal can control only one session at a time. When a session has
a controlling terminal, all the following are true:
•
Certain character sequences entered from that terminal cause signals to be sent to
all processes in the process groups of that session.
•
Certain characters entered from that terminal might receive special treatment.
•
Members of background process groups of the session are restricted from certain
kinds of access to the controlling terminal.
