I can see in the dump that my program is in subpool 251 and this is fetch
protected, so it explains the abend I guess.
SUBPOOL 251 KEY 08 OWNED BY TCB 008D2AA0
ADDRESS 20000000 LENGTH 00002000
FREE AREA 20000000 LENGTH 000000A8
Is there a way to force the program to go to subpool 244 for example, that is
not fetch protected?
I'm trying to create an easy test program that could simulate the situation
where the svc is called from a cics task running in key 9 trying to access key
8 storage. That case would fail if I start using MVCSK en MVCDK, and perhaps I
can add an ESTAE to do recovery in that scenario. First thing I would like to
try is to create an ESTAE that would just WTO the 0C4 situation, for example
'task running in key xx tried to access storage in key yy' .
The dump shows:
