Sounds ghastly - you either have to use Key-8 CSA (yuk) for the DCB/E or the participating ASIDs have to be executing in non-key8.
Open also builds other related control blocks - trying to locate them and adjust the pointers to CSA-versions would be a challenge and awful to support. I would consider some sort of PC-ss to the server ASID that pops I/O requests on a queue that is served in a serial fashion by a resident TCB in the server ASID.

And if so what considerations are required ? If I copy the DCB/DCBE to a Getmained Area that is below the line and in a COMMON subpool, could a PUT request be issued from other programs in other address spaces ? (i.e. Not the Address Space that issued the GETMAIN AND OPEN) The address of the DCB/DCBE in COMMON Storage would be placed in a NAME TOKEN PAIR after the DCB was Opened. Other Programs in other Address Spaces could retrieve the Name Token Pair and subsequently the DCB address and issue a PUT Request. The thought being that all I/O from the satelite address spaces would be directed to a physical dataset residing in the Address Space that owns (opened) the DCB. There are other techniques that accomlish the same thing but thats not the issue here. I am specifically asking about issuing PUT requests for a DCB/DCBE in Common Storage. Has anyone ever tried to accomplish this. Paul D'Angelo ____________________________________________________________ Get a life insurance quote online.
