Informix® JDBC Driver
Informix® JDBC Driver is a native-protocol, pure-Java driver (Type 4) that supports the JDBC specification.
For information about JDBC specification compliance, go to Java™ software development kit.
When you use Informix® JDBC Driver in a Java™ program to interact with the Informix® database, your session connects directly to the database or database server, without a middle tier.
You can use the JDBC driver for Java™ applications that access the Informix® database server. The installation includes ifxjdbc.jar driver and several support .jar files.
Javadoc™ pages describe the Informix® extension classes, interfaces, and methods in detail.
- UNIX™: Javadoc™ pages are in $JDBCLOCATION/doc/javadoc, where $JDBCLOCATION refers to the directory where you installed Informix® JDBC Driver.
- Windows™: Javadoc™ pages are located in %JDBCLOCATION%\doc\javadoc, where %JDBCLOCATION% refers to the directory where you installed Informix® JDBC Driver.
If you want to run Java™ user-defined routines (UDRs) in the database server, you must use the server-side version of the driver that is installed with the optional J/Foundation component of the database server. The server-side driver includes a jdbc.jar file, which is derived from the ifxjdbc.jar file. The J/Foundation Developer's Guide describes the interfaces and subprotocols that the Informix® JDBC Driver provides specifically for server-side JDBC applications, as well as restrictions that apply to server-side JDBC applications.
