Very similar level of sharing here. We used to have some application sharing
across sysplex boundaries, but it caused far too many problems versus what it
solved, so we replicated the data and apps spend a few minutes on the BDT
pipe over FCTC's or the ftp pipe over Hipersockets.

We choose to not allow any shared DASD across Sysplex boundaries.
It eliminates a whole class of problems.
We also chose to do the same thing in the mid-1990's.
And, at that time, the point was that DASD was cheap enough (especially
compared to the integrity problems) then.
Now, there is very
Nothing wrong with Sam's point of view and agree it is the safest.

In a few cases, we have to. Our Sun/STK VSMs and tape libraries are shared

There are two falacies regarding technology:
1. This is old, therefore good.
2. This is new, therefore better.

In those cases the integrity issues were more important than the cost of data
duplication.
