executable
executable. See object code file.
Executable and Linkable Format (ELF). A common standard for executable files and
object code. On HP NonStop™ servers, ELF replaced the less extensible Common
Object File Format (COFF) for native files.
execution mode. The emulated or real instruction set environment in which object code
runs. A TNS system has only one execution mode: TNS mode using TNS compilers
and 16-bit TNS instructions. A TNS/R system has three execution modes: TNS/R
native mode using MIPS native compilers and MIPS instructions, emulated TNS
execution in TNS interpreted mode, and emulated TNS execution in TNS accelerated
mode.
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™ operating system network that extends the concept of
fault-tolerant operation to networks of geographically distributed HP NonStop™
systems. If the network is properly designed, communication paths are constantly
available even if a single line failure or component failure occurs.
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. 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 every 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).
