Hi, I want to find out the Reason code for below :
00000000: 444C 4820 0100 0000 0000 0100 4D51 492E I am using the below logic to read the value:
Go to 1 row --> 6 column --> Reading the values in the order 3,4,1,2
I got 0001 and after converting to decimal I am getting the same. Please let me know if this correct. I am not able to find MQRC 0001 Reason code. |

Where is this emitted from?

How did you arrive at this logic? How did you determine (for example) that 4820 is not a specific endian representation of 2048 and the error is that you're applying persistence to a temporary dynamic queue?

It is emitted from Broker Local Queue. |

Next time you post, please include the right-hand end - where 444C 4820 is converted to printable characters.
444C 4820 is 'DLH ' (DLH and a single blank character) - an MQ dead-letter header.
If you examine this with the MQExplorer, it will decode the ReasonCode - if it's an MQ reason-code. In this case, it does not appear to be an MQ-created DLH, and does not contain an MQ Reason-Code.
You will need to look at the broker application that created the DLH to find out what it means.

Nothing is "emitted" from a queue - messages are put onto a queue.
Where it ended up says nothing about what produced it.

I got this logic from some documentation i searched on Google...which is mentioned as below:
To read the messages from DLQ
Go to 1 row --> 5 column --> Read the values in the order 3,4,1,2
eg.:- 0308 will turn into 0803
Convert from Hexa to Decimal using calculator, we will get a unique reason code
To find the error:- mqrc <reason code> |

To help you with the deciphering of the Reason field:
The above is in a little endian format (since the Version field is x'01000000'), so bytes need to be reversed. As bruce2359 mentioned, it is a DLH structure.
The Reason field = x'00000100'
Byte reversed (due to it being in little endian) is the following:
x'00010000' = 65,536

Which is explicitly a Broker DLQ MQRC value - it's an "application error code".
So, guess what.
Reading the message on the DLQ doesn't really help you figure out why it failed.
Try normal Broker troubleshooting. |
