HP NonStop Kernel
HP NonStop Kernel. The operating system for NonStop systems. The operating system
does not include any application programming interfaces.
IIOP. Internet Inter-ORB Protocol. A protocol used for communication between CORBA
object request brokers.
interoperability. The ability to have applications and computers from different vendors
(heterogeneous systems) work together on a network. Heterogeneous systems
interoperate by using standard application programming interfaces (APIs) and standard
formats and protocols. See also application programming interface (API) and
heterogeneous network.
interprocessor bus (IPB), A data channel that transmits data and messages between
processors in NonStop systems available prior to the NonStop servers. See also
ServerNet fabric.
I/O process. A system process that manages input/output devices. Applications use the
Guardian file system to send requests to I/O processes. See also file system.
IPB. See interprocessor bus (IPB),
J2EE. See Java 2 Platform, Enterprise Edition (J2EE).
Java 2 Platform, Enterprise Edition (J2EE). An environment for developing and deploying
enterprise applications. The J2EE platform consists of a set of services, application
programming interfaces (APIs), and protocols that provide the functionality for
developing multi-tiered, Web-based applications.
Java Database Connectivity (JDBC). A standard Java extension for data access that
allows Java programs to use a relational database API.
JDBC. See Java Database Connectivity (JDBC).
LAN. See local area network (LAN).
linear expandability. The linear relationship between the number of processors in a
NonStop system and the performance of the system. That is, adding a processor to a
NonStop system adds an entire processor’s worth of performance to the system.
link. An open of a server process within a server class. The server can then provide
services to a client process.
link management. The act of coordinating the sharing of links between client processes
and server processes.
load balancing. The act of distributing or balancing the server application workload among
a set of processors or server processes.
