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.

_RLD_LIB_PATH

The location where the Java VM and other Java programs search for the TNS/E jdbcMx PIC file. Set

_RLD_LIB_PATH explicitly or with the _RLD_LIB_PATH environment variable.

See Remote Duplicate Database Facility (RDF).

Remote Duplicate Database Facility (RDF)

The HP software product that does the following:

Assists in disaster recovery for online transaction processing (OLTP) production databases

Monitors database updates audited by the TMF subsystem on a primary system and applies those updates

to a copy of the database on a remote system

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.

server

One of the following:

An implementation of a system used as a stand-alone system or as a node in an Expand network.

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.

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.

set() method

A method used to modify a data item. For example, the SQLMPConnection.setAutoCommit() method changes

the transaction mode of the JDBC driver's connection to an SQL/MP or SQL/MX database. Compare to get()

method.
