IFX_NO_TIMELIMIT_WARNING environment variable
For users who dislike viewing warning messages, this feature is an alternative to redirecting the error output. Setting IFX_NO_TIMELIMIT_WARNING has no effect, however, on when a time-limited license expires; the software ceases to function at the same point in time when it would if this environment variable had not been set. If you do set IFX_NO_TIMELIMIT_WARNING, users will not see potentially annoying warnings about the impending license expiration, but some users might be annoyed at you when the database server (or whatever software has a time-limited license) ceases to function without any warning.
