there is no (easy) way to determine when a data set has data placed in it.
Yes and no, though some agent has to be waiting and periodically checking

Check DS1LSTAR in the format 1 DSCB.
Check DS1REFD in the format 1 DSCB
Intercept SMF writes. Assume the data set has been modified when a type 15 record appears for the data set.


And that is (using SMF/JES2) what a scheduler is doing.
