Question
Why am I receiving message DFHSM0001 with an abend0C4 abendAKEA in DFHSMPP during startup of my CICS region when running with vendor product IAM from Innovation Data Processing? I received the following error message, and the region would not initialize:
DFHSM0001 AN ABEND (CODE 0C4/AKEA) HAS OCCURRED AT OFFSET X'0694' IN MODULE DFHSMPP
Answer
Reviewing a dump from the program check showed the problem to be with Register 7. It is supposed to be a pointer to a PPX or Pagepool Extent Control area, there has been corruption of our PPX control blocks leading to this program check. A normal PPX should have the following eyecatcher:
| .&>DFHSMPPX |
| ESDSA .o...p(. |
| .....\.......=.. |
But one of our PPX control blocks have been overlaid, and does not have the correct eyecatcher above. Backing up from this area, to the page boundary I found an IAM eyecatcher:
-------------------
| IAMV.........o&. |
| .-.{............ |
| ................ |
| .o .....&.&..... |
-------------------
It appears IAM has overlaid our PPX control block. Contact Innovation Data Processing for further assistance.
