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.
Important:

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.
