Expand line-handler process
Expand line-handler process. A process pair that handles incoming and outgoing Expand
messages and packets. An Expand line-handler process handles direct links and also
binds to other processes using the Network Access Method (NAM) interface to support
Expand-over-X.25, Expand-over-FOX, Expand-over-ServerNet, Expand-over-TCP/IP,
and Expand-over-SNA links. See also Expand-over-ServerNet line-handler process.
Expand network. The HP NonStop™ Kernel operating system network that extends the
concept of fault-tolerant operation to networks of geographically distributed HP
NonStop S-series systems. If the network is properly designed, communication paths
are constantly available even if there is a single line failure or component failure.
Expand node. A system in an Expand network. See also node.
Expand node number. A number in the range 0 through 254, sometimes referred to as the
system number, that identifies a node in an Expand network. Each Expand node
number must be unique within the network. See also ServerNet node number.
Expand-over-ServerNet line. The single line associated with an Expand-over-ServerNet
line-handler process. Note that an Expand-over-ServerNet line has the same name
and logical device number as its Expand-over-ServerNet line-handler process.
However, the line does not have the same states as the line-handler process.
Expand-over-ServerNet line-handler process. An Expand line-handler process that uses
the NETNAM protocol to access the Network Access Method (NAM) interface provided
by the ServerNet cluster monitor process, $ZZSCL. The Expand-over-ServerNet line-
handler process handles incoming and outgoing Expand messages. It also handles
packets leaving the server and security-related messages going between systems
within a ServerNet cluster. Each node in a ServerNet cluster must be configured with
an Expand-over-ServerNet line-handler process for each other node in the ServerNet
cluster.
expansion service processor (ESP). A service processor (SP) that is not a master service
processor (MSP). ESPs occur in pairs in groups 02 through nn (not in group 01). See
also master service processor (MSP)
.
explicit DLL. See explicit dynamic-link library (explicit DLL).
explicit dynamic-link library (explicit DLL). A dynamic-link library (DLL) that is named in
the libList of a client or is a native-compiled loadfile associated with a client.
export. To offer a symbol definition for use by other loadfiles. A loadfile exports a symbol
definition for use by other loadfiles that need a data item or function having that
symbolic name.
export digest. A mathematical hash of the exported symbol names and locations in a
library. Two libraries with the same export digest are interchangeable in that they both
export the same symbols at the same locations; they are not necessarily semantically
equivalent.
