Hello Listers, I'd like to be able to update a common storage area across all CICS and batch regions. I've looked at IARV64 REQUEST=GETCOMMON, but it seems that it requires supervisor state and/or key 0-7.
It seems that something like issuing a STORAGE macro similar to: STORAGE OBTAIN LENGTH=32768,SP=241,KEY=x,LOC=31,OWNER=SYSTEM ...from an authorized program would allocate the storage needed. But I don't know the rules for accessing it from "user-mode" (unauthorized, key 8) programs like a CICS application. a) Given the address of the storage obtained like that, can any user-mode program read that storage? b) Could a user-mode program update that storage? c) Should the KEY parameter be specified, and if so, what value should I use. Afaik it has to be 0-7 since User-key CSA was outlawed. d) Am I correct that there isn't an IRAV64 option that will allow a user-mode program to update the storage? Thanks for your help!
