Hello all:
After reading up on <Extended Addressability Guide> ,I am confused on
ASN resue issue. According to the book,if address space owns a spaces
switch ET and connect it to the system lx,then this address space's ASID is
not reusable for the duration of IPL. This is because other address space
could pass control to code running in the address space that reused this
ASID.My question is:
1. Before service provider(owner of ET) termination, the ET was usually
destroyed(ETDES PURGE=YES), How could the other address space pass
control to PC running in the address space which reused the service provider's
ASID. How could this happen?
2. does ASN-reuse-facility have something to do with it,how the ASN-
reuse-facility remedy the potential system integrality problem.
I searched for a couple days but can't find more information,so could you
please explain more details for me. thanks
