Dear Support Team,
Our application gets segmented MQ messages by the queuemanager.
The MQ produced an FDC file, and the AMQ7924 error message in the AMQERR01.LOG, but I cannot find relevant information about the solution.
I could reproduce the problem, so I was trace the MQ, but it is too big to attach here, I should send if someone need it.
I copied the errors below, if someone need more information, please ask me to send it.
Any help would be appreciated!
AMQERR01.LOG
*************************

Host(lxveld1)
AMQ7924: Bad length in the PCF header (length = 4206866).
EXPLANATION:
Message data conversion cannot convert a message in Programmable Command Format
(PCF) because the PCF header structure contains an incorrect length field.
Either the message has been truncated, or it contains data that is not valid.
ACTION:
Use the standard facilities supplied with your system to record the problem
identifier, and to save the generated output files. Do not discard these files
until the problem has been resolved. Use the file containing the Message
Descriptor of the message to determine the source of the message and to see how
data that is not valid became included in the message.

So why would a segmented message have a PCF header? That does not sound right to me
Can you take a dump of the offending message(s) with something like amqsbcg?
Otherwise, it looks like a PMR Issue.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Yes I know, but I did not find a better addressee. Next time I will pay more attention. |

"Folks", "experts", "random strangers on the internet", "people with too much time on their hands", anything really.

"Chaps"?
"All"?
What my most worthy associate is correctly trying to do is underline that we're not any kind of support team with any kind of SLA, nor does our advice come with any kind of backing save our perceived wisdom.
In contrast with (for example) the support team on the back of a PMR, which has clearly defined SLAs and who's advice comes with the full weight of IBM behind it.

I checked the code with a developer, which creates the message, it is not manipulating any MQEPH fields.
Unfortunately, the 7.0.1 mq version is unsupported right now, I can not open a PMR.
If You want to get extra data, please write me to gerimqseries@gmail.com.
Now the workaround is to set the queues and channels MAXMSGL property to a higher value, then the message will be not segmented, and there is no error when mqget issued. |
