NonStop Server for Java 7.0 Programmer's Reference

Private Key An encryption key that is not known to all parties.
Protocol A set of formal rules for transmitting data, especially across a network. Low-level protocols define
electrical and physical standards, bit-ordering, byte-ordering, and the transmission, error detection,
and error correction of the bit stream. High-level protocols define data formatting, including the
syntax of messages, the terminal-to-computer dialogue, character sets, sequencing of messages,
and so on.
Pthread A POSIX thread.
Public Key An encryption key that is known to all parties.
Pure Java Java that relies only on the Core Packages, meaning that it can run anywhere.
R

Remote Duplicate
Database Facility
(RDF)
The HP software product that does the following:
Assists in disaster recovery for OLTP production databases.•
• Monitors database updates audited by the TMF subsystem on a primary system and applies
those updates o a copy of the database on a remote system.
Remote Method
Invocation (RMI)
The Java package used for homogeneous distributed objects in an all-Java environment.
Requestor See client.

rmic The Java RMI stub compiler, which generates stubs and skeletons for remote objects.
rmicregistry The Java Remote Object Registry, which starts a remote object registry on the specified port on
the current host.
S
Scalability The ability to increase the size and processing power of an online transaction processing system
by adding processors and devices to a system, systems to a network, and so on, and to do so
easily and transparently without bringing systems down. Sometimes called expandability.
Scalable TCP/IP
(SIP)
A NonStop Server for Java feature that transparently provides a way to give scalability and
persistence to a network server written in Java.
Scavenge Young generation garbage collection is also know as scavenge.
Serialization See Object Serialization.
Serialized Object An object that has undergone object serialization.
serialver The Serial Version Command, which returns the serialVersionUID of one or more classes.

2. The hardware component of a computer system designed to provide services in response
to requests received from clients across a network. For example, NonStop system servers
provide transaction processing, database access, and other services.
3. A process or program that provides services to a client. Servers are designed to receive
request messages from clients; perform the desired operations, such as database inquiries
or updates, security verifications, numerical calculations, or data routing to other computer
systems; and return reply messages to the clients.
Servlet A server -side Java program that any World Wide Web browser can access. It inherits scalability
and persistence from the Pathway CGI server that manages it.
The Java class named servlets executes in server environments such as World Wide Web servers.
The Servlet API is defined in a draft standard by Oracle. The servlets class is not in the Core
Packages for the JDK.
