The OpenLink Drivers for JDBC are packaged either as a bundle alongside the other OpenLink data access drivers (ODBC and OLE-DB) that make up the OpenLink Universal Data Access Driver Suite or as a separate release archive which contains only the OpenLink Megathin Drivers for JDBC. The Megathin Driver for JDBC is a 100% pure Type 3 Network enabled Java Driver. If you are not installing these Drivers from a CD you would have to visit the OpenLink Web Site's download page, http://www.openlinksw.com, to obtain these Drivers.

OpenLink Drivers for JDBC Installation & Configuration

Once you have downloaded your OpenLink drivers for JDBC using the instructions provided above, the next step in the process is the actual configuration of these drivers for use within your operating environment. Java is operating system independent by virtue of its core philosophy, but JDBC Drivers may or may not be operating system independent as this is JDBC Driver format and implementation specific. The sections that follow walk your through the OpenLink Driver for JDBC installation and configuration process.

Java Based Local Client-Server

Mon, 16 Nov 2009 14:28:45 GMT

In this scenario the Java Virtual Machine is acting as the host of your OpenLink client component for JDBC (a 100% Pure Java Driver for JDBC). The operating system hosting your Java Virtual Machine, also hosts the OpenLink Server server components for JDBC. Thus, you are going to install your OpenLink Client and Server components for JDBC on the same machine.

Java Based Client-Server (2-Tier) Installation

Mon, 16 Nov 2009 14:28:45 GMT

In this scenario the Java Virtual Machine and OpenLink Drivers for JDBC reside on separate to OpenLink Server server components for JDBC and Database Connectivity. Thus, you are going to install your OpenLink Client and Server components for JDBC on separate machines, one acting as the Client and the other the Server. The Server also hosts the actual database engine that you will be connecting to via JDBC.

Java Based Application-Server (3-Tier) Installation

Mon, 16 Nov 2009 14:28:45 GMT

In this scenario the Java Virtual Machine and OpenLink Drivers for JDBC and the OpenLink Server server components for JDBC reside on the same machine which is known as the Application Server. The OpenLink Database Server components reside on a separate Database Server machine (if required) which hosts the database that you will be connecting to via JDBC.

OpenLink Server Components Configuration

Mon, 16 Nov 2009 14:28:45 GMT

The OpenLink JDBC agent and OpenLink Database agents form the OpenLink server components, In the prior section you would have installed these components on the appropriate server machine. Following installation you have to configure these server components in order to enable connectivity between your backend database(s) and your OpenLink Driver for JDBC. Both of these components are exposed to your OpenLink Driver for JDBC via the OpenLink Request Broker. This new OpenLink release enables the direct connection to an OpenLink Database agent from your OpenLink Java client classes, as JDBC support in now built in to the database agents. Thus you no longer have to connect via the OpenLink JDBC Agent proxy, as in the past, although connection via this method is still supported. Obviously connecting directly to the Database agent will provide better performance, and is now the recomended connection method whenever possible. OpenLink Database Agents are the OpenLink data access server components that actually provide database connectivity services to your OpenLink Driver for JDBC. A Database Agent exists for each database engine supported by OpenLink, the supported database list currently includes: Oracle, DB2, Informix, Sybase, Ingres, Progress, Microsoft SQL Server, OpenLink Virtuoso, Solid, PostgresSQL, and other ODBC based databases. Please follow the instructions provided in the OpenLink Database Agents configuration guide prior to attempting to use your OpenLink Drivers for JDBC (if you haven't already done so as part of the installation process).

OpenLink Drivers for JDBC Utilization

Mon, 16 Nov 2009 14:28:45 GMT

OpenLink Drivers for JDBC are available in three different JDBC Driver formats. JDBC Applets, Applications, Bean Components, and Servlets communicate with JDBC drivers through JDBC Uniform Resource Locators (URLs). Theses URLs are service request and binding formats implemented slightly differently for each OpenLink Driver for JDBC format. The general JDBC URL format is: jdbc::[jdbc implementation specific URL attributes]

OpenLink Demonstration Programs

To assist you further during your utilization or evaluation of OpenLink's Drivers for JDBC a number of demonstration JDBC compliant Applets and Applications are bundled with your OpenLink Driver for JDBC installation, these programs are provided in both binary and source code format for your free use. The sections that follow guide you through the process of using these programs
