ABORT. A sensitive command that terminates the operation of a NonStop™ IPX/SPX object
abruptly without regard for interruption of data transfer.
ABORTING. The state of an object, indicating that it is responding to an ABORT
command
or some type of malfunction.
Access Control Server (ACS). An optional NonStop™ Himalaya S-series server process
that can be used to grant or deny workstation access to the Remote Server Call (RSC)
services on the NonStop™ Himalaya S-series server. Users must create their own RSC
ACS.
access list. The file maintained by the LAN Manager (LANMAN) process
that defines which
ServerNet addressable controllers (SACs) a LAN Monitor (LANMON) process owns.
action event. An event that requires operator intervention to resolve. Each subsystem
determines which events are action events by including a unique Event Management
Service (EMS) token in the event message. Action events are reported as pairs of event
messages: an action-attention message that reports the problem and an action-
completion message that reports the resolution.
adapter card. See network adapter card (NIC)
.
ADD. A sensitive command
that adds a process with its associated attributes to the
NonStop™ IPX/SPX subsystem.
address mask. A bit mask used to select bits from an Internet address for subnet addressing.
The mask is 32 bits long and selects the network portion of the Internet address and 1 or
more bits from the local portion.
address resolution. Conversion of an Internet address into a corresponding physical address.
Depending on the underlying network, address resolution may require broadcasting on a
local network. See also Address Resolution Protocol (ARP)
.
Address Resolution Protocol (ARP). The Internet protocol used to dynamically bind a high-
level Internet address to a low-level physical hardware address. ARP applies only across
a single physical network and is limited to networks that support hardware broadcast
.
ALTER. A sensitive command
that changes the values of one or more attributes of an object.
API. See application program interface (API)
.
application program interface (API). A general term for a software interface that allows an
application program to talk to or control another service-providing program so that the
application program can use the services provided. For example, an application program
in the form of a client
might use an API to talk to a server program.
ARP. See Address Resolution Protocol (ARP)
