Resolution

The problem comes from the OMVS profile environment.

After modifying the profile environment on OMVS by resetting the DISPLAY variable to null, the following command on OMVS can be used to reset the DISPLAY environment variable on OMVS.

    export DISPLAY=''   (Note: use two single quotes to indicate a null value for DISPLAY)

The user may also need to add the JAVA options with IBM_JAVA_OPTIONS=-Xms1024m -Xmx1024m parameters, allowing the installation to be successful.
