I am running few remote ssh sessions

# ls /dev/pts/  
0  1  2  ptmx

One of the sessions running a live program, which depends on some environment variable(e.g. $CATALINA_OPTS).

I want to change the value of this environment variable and apply on fly to the running instance of the tty and the program in it. I do not want to kill the current tty or logout.

Thanks for any hint.

    Terminals do not have environment variables. Processes do. This is a fundamental misconoception in this question. – JdeBP May 29 '20 at 09:17
