As Steve said that is what X37 type software does.  The X37 software steps in 
to determine if it should try to help recover from a X37 error.  Now if that 
type of software is not in the cards, then maybe looking at how datasets are 
allocated might be a way to help reduce X37 errors.

If SMS is in the picture, you could look at some type of general rule around 
volume count.  The down side to that is it takes up room in the TIOT below the 
line.  If you open/allocate lots of datasets you might run out of room in the 
TIOT.  If you are pushing all TIOT stuff above the line then space may not be 
an issue.

Keeping with SMS maybe look at dataset allocation stuff.  It comes down to the 
size of the primary and secondary allocation.  Maybe some datasets are better 
off with a large primary and small secondary.  While other datasets might work 
better with a small primary and large secondary.

As far as I know SMS changes really only come into play during dataset 
allocation.  Will not help with datasets already allocated.

What you’re describing and wanting to do is exactly how the product stop X 37 
works
