Don't be so sure...  my MVS folks are telling me that there is no way TSM=
 is
over riding their micro-code hardware level compression.  (but I will dou=
ble
check with them and again as well as with
Tivoli). =20

With regard to compressing data twice, I disagree.  There's something ver=
y
wrong with it.  That's why it is strongly recommended not to do it. (not
just with TSM, but with all data)  Some data that
goes thru multiple compression routines can "blow up" to 2x the size the
file started out as.

And finally, the reason we turn compression on at the client, is to compr=
ess
it before it rides our very slow network.  Otherwise, I wouldn't. =20
