Broker is generating a coredump file. The file is unreadable and its size is huge. From the system log, I've extracted the following...
| Code: |

END OF SYMPTOM DUMP |
What is the cause of the coredump? Whenever it happens, the broker will stop picking up messages from its input queues. And the only remedy is by stopping and restarting it.
The broker is residing on an OS/390 system.
At first, I thought this was a fixed-decimal parsing issue (noted on one of my posts), but this time it just occured even when I'm not parsing a fixed decimal! (I was parsing a string, which never gave me any errors before)
Please help.
Thanks. |

Hi,
Completion Code = 0C4 means "The system detected a protection exception", so it's time to contact IBM service. You will need the coredump ( TERSEd ) and probably collect stderr/stdout/syslog/etc data - see WMQI "Problem Determination Guide" for more details...
BTW: Which WMQI release/CSD do you have ? |

I have contacted our IBM representative, but they have yet to give me a reply on this. However I really need to resolve this issue as soon as possible because there is on-going testing.
Can you clarify what does it mean by "The system detected a protection exception"?
I am using WMQI 2.1 CSD03.
Thanks! |

CSD05 may help to solve the problem, in my 390 environment CSD05 works really stable.
Otherwise you have to wait for answer from WMQI Service Team...
FYI:
Protection exception means:
CEE3204S The system detected a protection exception (System Completion Code=0C4).
Explanation: your program attempted to access a storage location to which it was not authorized.
Programmer Response: Check your application for these common errors:
. Using the wrong AMODE to reference storage
. Trying to use a pointer that has not been set
. Trying to store data into storage reserved for the system
. Using an invalid index to an array
System Action: The thread is terminated. |
