Ah, "I see", said the blind man.

With that restriction, I still have a gut feel that there is an easier way to solve this, but off hand, can't think of any.

If I understand (that is sometimes a very big "if") the standard tablespace full alert would work if it could be tuned down to something like "alert when 99.9995 % full, alarm when 99.9997 % full" Not that it can be that fine, but if it could . . . . am I right?
