partitions.
class path
The location where the Java VM and other Java programs that are located in the directory search for class libraries (such as
classes.zip). Include the t4sqlmx.jar file in your class path. The t4sqlmx.jar file is in the location where you installed this product. You
can set the class path explicitly or with the
CLASSPATH environment variable.
client
A software process, hardware device, or combination of the two that requests services from a
server. Often, the client is a process
residing on a programmable workstation and is the part of a program that provides the user
interface. The workstation client might also
perform other portions of the program logic. Also called a requester.
CLOB
Short for Character Large OBject, text data stored as a single entity in a database management system. A Java
Clob object (Java type,
java.sql.Clob) corresponds to the SQL CLOB data type.
command
The operation demanded by an operator or program; a demand for action by, or information from, a subsystem. A command is typically
conveyed as an interprocess message from a program to a subsystem.
concurrency
A condition in which two or more transactions act on the same record in a database at the same time. To process a transaction, a
program must assume that its input from the database is consistent, regardless of any concurrent changes being made to the database.
TMF manages concurrent transactions through concurrency control.
concurrency control
Protection of a database record from concurrent access by more than one process. TMF imposes this control by dynamically locking and
unlocking affected records to ensure that only one transaction at a time accesses those records.
connection pooling
A framework for pooling JDBC connections.
Core API
The minimal set of
APIs that developers can assume is present on all delivered implementations of the Java Platform when the final API
is released by Oracle. The NonStop Server for Java 4 conforms to every Core API in the
JDK. Core API is also called Java Core
Classes and Java Foundation Classes.
D
Data Control Language (DCL)
The set of data control statements within the SQL/MP language.
Data Manipulation Language (DML)
The set of data-manipulation statements within the SQL language. These statements include INSERT, DELETE, and UPDATE, which
cause database modifications that
Remote Duplicate Database Facility (RDF) can replicate.
data source
A logical name that defines the information required to access data.
On the client side, it defines the driver name, network address, and specific attributes such as catalog and schema names.
On the server side, it defines startup values, number of servers in a pool, Guardian defines, SQL/MX control statements, and
resource management policies. On the server side, data source is referred to through the serverDataSource property.

Distributed transactions
A transaction that spans across multiple databases.
driver
A Java class that implements the java.sql.Driver interface. For example, the com.tandem.t4jdbc.SQLMXDriver is a Type 4 JDBC driver
that implements the
java.sql.Driver interface (see HP JDBC Type 4 Driver for NonStop SQL/MX).
DriverManager
The JDBC class that manages drivers.
E
exception
An event during program execution that prevents the program from continuing normally; generally, an error. Java methods raise
