Concurrent user 4GL

Hello Guys. I'd like to know how to determine the number of concurrent users or sessions that uses my 4GL application. No informix.

If you are using a *nix O/S, you could run something like "ps -ef | grep <my 4gl program name> | grep -v grep | wc -l". If you want a snapshot of how many users are running the program at various times, you could set up a cron or recurring "at" job that runs that ps script once (or multiple times) an hour.
