Using DBIntegrator
Client for JDBC
[Top] [Prev] [Next] [Bottom]
Introducing DBIntegrator Client for JDBC
DBIntegrator Client for JDBC is the universal
Java Database Connectivity (JDBC) client-side driver component of DBIntegrator.
DBIntegrator Client connects users and data over Local Area Networks (LAN),
Wide Area Networks (WAN), Intranets or the Internet. The DBIntegrator server
component is included with Unify DataServer and Unify DataServer/ELS,
and provides the database connectivity services.
This DBIntegrator Client component contains a JDBC 2.1 driver.
DBIntegrator Client for JDBC is a "100%
Pure Java" driver capable of connecting to any data source from
JDBC-enabled applications or Java applets.
What's New
This release delivers the JDBC 2.1 Core API and the JDBC 2.0 Optional Package
functions, as specified in the JDBC specifications produced by Sun Microsystems:
1. JDBC 2.1 Core API: Performance Enhancements
2. JDBC 2.1 Core API: BigDecimal Methods
3. JDBC 2.1 Core API: Object Resolution
4. JDBC 2.1 Core API: Time Zones
5. JDBC 2.0 Optional Package Classes:
SimbaDataSource (implements javax.sql.DataSource, java.io.Serializable,
javax.naming.Referencable)
SimbaObjectFactory (implements javax.naming.spi.ObjectFactory)
SimbaRowSet (implements javax.sql.RowSet, java.io.Serializable,javax.naming.Referenceable)
SimbaPooledConnection (implements javax.sql.PooledConnection)
SimbaConnectionPoolDataSource (implements javax.sql.ConnectionPoolDataSource,
javax.sql.ConnectionEventListener, javax.naming.Referenceable, java.io.Serializable)
SimbaConnectionHandle (implements java.sql.Connection and acts as a wrapper
to a Connection object)

About JDBC
JDBC is a set of standard interfaces that enable Java applications
and applets to access multiple database management systems using Structured
Query Language (SQL). The JavaSoft JDBC Driver Manager handles multiple
drivers connecting to different databases.
About the Documentation
This online manual contains information specific to
installing DBIntegrator Client for JDBC, deploying it with Java applications
and applets, and setting up data source connections. For information about
installing and using DBIntegrator, see Unify DBIntegrator: Installation
and Configuration Guide and Unify DBIntegrator: User's Guide
(available in electronic format or hard copy). Note that chapters in that
documentation referring to the DBIntegrator Client are ODBC-specific and
you should consult this document for JDBC-specific information.
System Requirements
In order to use the
DBIntegrator Client for JDBC's JDBC 2.1 driver,
the following components are required:
-
Java Development Kit version 1.3.1 or higher
-
The CLASSPATH environment variable properly set (see Setting
the CLASSPATH Variable section)
-
Unify DataServer 7.1 or higher installed on an NT or UNIX server, or DataServer
ELS 6.5 or higher installed on a UNIX server, with the DBIntegrator Server
option enabled.
Deployment Strategies
DBIntegrator can be deployed in a number of ways to
suit your particular environment, including using it as a driver with a
Java application or bundling it with a Java applet.
The figures below illustrate both methods:
NOTE: The initial release of the DataServer ODBC driver only supports
accessing local databases. In these examples the DataServer ODBC
driver (including the web server) and the database server must exist on
the same machine, limiting you to a two-tier deployment. Future releases
of the DataServer ODBC driver may support accessing remote databases, allowing
three-tier deployment. Also note that the DataServer ELS ODBC driver
for DBIntegrator is not scheduled to support accessing remote databases.
