remote procedure call (RPC)
A client/server mechanism that enables processes on client systems to execute procedures
stored on remote systems. On the client side, the RPC software encapsulates the
parameters for a procedure call in a message and sends the message to a server. The
server unpacks the parameters, calls the procedure, and sends a response to the client.
From the application program’s perspective, remote procedures are indistinguishable from
local procedures because they are called in the same manner.
remote user agent (RUA)
The client software of an X.400 mail system that provides remote users with access to a
message store.
resilient cluster
Two or more Intel nodes, shared disk drives, and multiple (redundant) physical and virtual
network connections that make system resources highly available to clients. To the end
user, the resources appear to be available from a single system. Cluster software can
automatically detect failure of hardware or an application on one node and restart the
application on the other (surviving) node of the cluster with little noticeable interruption of
service. See also cluster.
