Answer Posted / raghu
It defines the cross-region and cross-system sharing
capabilities of the dataset. Syntax is SHR(Crvalue, CSvalue)
value 1 means multiple read OR single write (read integrity)
2 means multiple read AND single write (Write integrity) 3
means Multiple read AND multiple write 4 is same as 3, which
refreshes the buffer with every random access. default is
SHR(2 3).
