JRE version 11, 17 or 21 must be installed on your machine in order to use isCOBOL UDBC. For best results and performance, install the latest update build available for your platform.

Note - When using Java 21 the default encoding is UTF-8 on every operating system.

Self-extracting setups are provided for the Windows platform.

On Unix/Linux platforms Java may be already installed. If it’s not the case, you can install it using the appropriate system commands (e.g. yum, or apt-get).
