When the INFORMIXTERM environment variable is set to terminfo, the runtime system will use the ncurses or curses library of the UNIX™ system to display and interact with the terminal device, according to the TERM environment variable.
Make sure that the libncurses.so or the libcurses.so library is installed on your UNIX operating system.
The TERMINFO environment variable can be used to define a different terminal capabilities database as the default. If your UNIX system is properly configured, you should not have to set the TERMINFO environment variable.
