This chapter includes the following sections:
This document is a resource for software developers and system administrators who develop and support applications that use the Java Database Connectivity (JDBC) API. It also contains information that is useful for business analysts and system architects who are evaluating WebLogic Server. The topics in this document are relevant during the evaluation, design, development, pre-production, and production phases of a software project.
It is assumed that the reader is familiar with Java EE and JDBC concepts. This document emphasizes the value-added features provided by WebLogic Server JDBC and key information about how to use WebLogic Server features and facilities to get an JDBC application up and running.
This chapter, Introduction and Roadmap, introduces the organization of this guide.
Using WebLogic JDBC in an Application, explains how to use a JDBC connection in your application.
Using DataSource Resource Definitions, explains how to use a DataSource resource definition in your application.
Performance Tuning Your JDBC Application, describes how to design JDBC connection usage in your applications for the best performance.
Using WebLogic-branded DataDirect Drivers, describes how to use WebLogic-branded DataDirect drivers in your applications.
Using WebLogic Wrapper Drivers, describes how to use some alternative drivers for getting a JDBC connection from a data source.
Using API Extensions in JDBC Drivers, describes special programming considerations for third-party drivers in your applications.
Using RowSets with WebLogic Server, describes how to use rowsets in your applications.
Troubleshooting JDBC, describes some common JDBC problems and solutions.
This document contains JDBC-specific programming information.
For comprehensive guidelines for developing, deploying, and monitoring WebLogic Server applications, see the following documents:
Administering JDBC Data Sources for Oracle WebLogic Server is a guide to JDBC configuration and management for WebLogic Server.
Developing Applications for Oracle WebLogic Server is a guide to developing WebLogic Server applications.
Deploying Applications to Oracle WebLogic Server is the primary source of information about deploying WebLogic Server applications in development and production environments.
In addition to this document, Oracle provides a variety of JDBC code samples that show JDBC configuration and API use, and provide practical instructions on how to perform key JDBC development tasks.
MedRec is an end-to-end sample Java EE application shipped with WebLogic Server that simulates an independent, centralized medical record management system. The MedRec application provides a framework for patients, doctors, and administrators to manage patient data using a variety of different clients.
MedRec demonstrates WebLogic Server and Java EE features, and highlights Oracle-recommended best practices. MedRec is optionally installed with the WebLogic Server installation. You can start MedRec from the ORACLE_HOME\user_projects\domains\medrec directory, where ORACLE_HOME is the directory you specified as the Oracle Home when you installed Oracle WebLogic Server. For more information, see "Sample Applications and Code Examples" in Understanding Oracle WebLogic Server.
WebLogic Server optionally installs API code examples in the ORACLE_HOME\wlserver\samples\server directory, where ORACLE_HOME represents the directory where you installed WebLogic Server. For more information, see "Sample Applications and Code Examples" in Understanding Oracle WebLogic Server.
This release includes the following new and changed features:
For a comprehensive listing of the new WebLogic Server features introduced in this release, see What's New in Oracle WebLogic Server 12.2.1.
In previous releases, the PasswordEncrypted attribute was not supported in data source definitions. This restriction has been removed. For more information, see Using an Encrypted Password in a DataSourceDefinition.
