remote procedure call system
remote procedure call system. A set of facilities that includes a programming library,
network resource mapping, and binding services to provide a mechanism for a client
process to execute a procedure on a remote server. A remote procedure call system is
a subset of the Distributed Computing Environment (DCE) and of other products.
remote processor. A processor in a node other than the node running the ServerNet
cluster monitor process (SNETMON) that is reporting status about the processor.
remote switch. An HP NonStop Cluster Switch (model 6770) or HP NonStop ServerNet
Switch (model 6780) in a ServerNet cluster that is not directly connected to the server
that you are logged on to. The OSM Service Connection and the TSM Service
Application cannot perform any actions on a remote switch. To perform actions or get
additional information on a remote switch, use the OSM Service Connection (for either
the 6770 or 6780 switch) or TSM Service Application (for the 6770 switch only) to log
on to a server that is directly connected to the switch.
remote system. An active ServerNet node to which the local system has active external
ServerNet paths. Contrast with local system.
request packet. A ServerNet packet sent from one ServerNet device to another, requesting
either a read action or a write action on the part of the receiving device. In the case of
a write request, the packet contains the data to be written. The receiving device is
expected to take the appropriate action and return a response packet to the device that
sent the request packet. See also response packet, ServerNet packet, and ServerNet
transaction.
requester missed address file (RMAF). A file used by the HP NonStop™ operating
system during memory-caching operations.
reserved symbol. An identifier that is reserved for use by system or compiler language
implementors.
resistance. The measure of noninductive or capacitive opposition (impedance) to current
that limits the amount of current that can be produced by an applied voltage.
Conductors have very little resistance; insulators have a large amount of resistance.
Resistance is measured in ohms.
resource. A component of a computer system that works with other components to process
transactions. Terminals, workstations, processors, memory, disk drives, processes,
files, and applications are examples of resources.
response. The information or confirmation supplied by a subsystem in reaction to a
command. A response is typically conveyed as one or more interprocess messages
from a subsystem to an application.
response packet. A ServerNet packet returned from one ServerNet device to another,
responding to an earlier received read request or write request. In the case of
responding to a read request, the response packet contains the data that the
