Hi experts,
I am a beginner of dump reading and have a simple S0C4. Could anyone please
guide me.
The PSW looks 079D0000 9B76D1B4. The failing instruction is L R15,X'0C'(R15).
The value of R15 is 000128FC.
The output of VERBX VSMDATA shows;
DATA FOR SUBPOOL 251, KEY 8 FOLLOWS:
-- DQE LISTING (VIRTUAL BELOW, REAL BELOW)
DQE: ADDR 00012000 SIZE 2000
FQE: ADDR 00012000 SIZE 870
DQE: ADDR 0001B000 SIZE 2000
FQE: ADDR 0001B000 SIZE 480
So my analysis is that a pgm running with storage key 9 tries to access key 8
fetch protected storage and the access is denied.
Am I correct ?
How do I know the area is fetch protected ? Is there any IPCS command to tell
fetch protected or not?
Thanks in advance.
Al Chu
