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.
requester See client.
RMI See Remote Method Invocation (RMI).
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.
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.
Also, the command to run the Serial Version Command.
server An implementation of a system used as a stand-alone system or as a node in an Expand
network.
1.
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 Sun Microsystems. The servlets class is not
in the Core Packages for the JDK.
shell The command interpreter used to pass commands to an operating system; the part of the operating
system that is an interface to the outside world.
SIP See Scalable TCP/IP (SIP).
skeleton In RMI , the complement of the stub . Together, skeletons and stubs form the interface between
the RMI services and the code that calls and implements remote objects.
socket A logical connection between two application programs across a TCP/IP network.
SQL/MP See HP NonStop SQL/MP.
SQL/MX See HP NonStop SQL/MX.
SQLJ Also referred to SQLJ Part 0 the "Database Language SQL—Part 10: Object Language Bindings
(SQL/OLB) part of the ANSI SQL-2002 standard that allows static SQL statements to be embedded
directly in a Java program.
