Download and install the Java Runtime Environment (JRE)

JDK version 1.6 (or later) from Oracle must be installed on your machine in order to use isCOBOL UDBC. For best results and performance, install the latest JDK version available for your platform.

Note - if you have previously installed a Java Development Kit (JDK), you can use the JVM of the development kit.

1.	Go to "http://www.oracle.com/technetwork/java/javase/downloads/index.html".

2.	Click the first "Download" button below "JRE"

3.	Accept the license agreement and click on the appropriate filename to download the JRE installer. For example, for Windows 32-bit click on "jre-7-windows-i586.exe".

4.	Run the JRE installer or self-extracting binary. JRE installation instructions can be found at "http://www.oracle.com/technetwork/java/javase/index-137561.html".

 

After installation, verify that the PATH variable includes the JRE bin directory.

On Windows platforms, the JDK and JRE are installed in subdirectories of "C:\Program Files\Java". For example:

C:\Program Files\Java\jre7

On UNIX and Linux platforms, the JDK and JRE may be installed in any directory. It is common to see "/opt/java" on Linux. For example:

/opt/java/jre7

Note - Oracle doesn’t provide Java for every UNIX platform. Some UNIX platforms provide their own Java environment. Refer to your UNIX documentation for details.
