Well I got a message in DLQ while browsing the message from the queue it is throwing 2080 error. I know what 2080 means i.e the size of message that application is putting to queue is too large than buffer size.
In order to process the message from dlq what action should be taken?
if your suggestion is increase the buffer then how? |

Search for dead-letter queue handler supplied application.

And when you read this, what conclusions did you reach?
That your application could allocate a new buffer of the size returned and try the MQGET again?
I have to assume this error is coming from the application you are using to read the DLQ, right?
What tool is that? RfhUtil or RfhUtilC or qload or what? |

Browsing the DLQ with what application? MQExplorer? Something else?
How big (length) is the message supposed to be? How big is it in the queue?
If runmqdlq gets the same 2080, then modify the supplied source-code MQ_INSTALLATION_PATH\tools\c\samples\dlq to make the buffer larger.

You could install the MQExplorer on Windows or Linux, and use it to remotely connect to AIX, and then browse the DLQ. You can change MQExplorer message browsing preferences to see more of the message than amqsbcg displays for you.

Okay.
I'm interested.
What part of the message doesn't amqsbcg show you? |

It's been quite some time since I looked at the source-code for amqsget, amqsbcg, and the other MQGET utilities. If memory serves, the buffer size was 100 bytes; so, if your message is longer than 100 bytes, you would receive the 2080 reason code.
Source-code is provided in the MQ installation. Expand the buffer, and recompile.

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

That's amqsget - amqsbcg streams everything

Well, no. amqsbcg0.c shows the same buffer size. |

From source of amqsbcg0.c:
| Code: |
| define BUFFERLENGTH 65535 /* Max length of message accepted */ |
Must be a big message...

Also, later versions of amqsbcg0.c set the MQGMO_ACCEPT_TRUNCATED_MSG GMO option so that larger than 64 K messages are just accepted with the truncation.
| Code: |
/* Accept but truncate the data received for messages */
/* larger than the 64K buffer */
GetMsgOpts.Options += MQGMO_ACCEPT_TRUNCATED_MSG ; |
