I am working on a 5.3 install on HPUX. I have created the sample queues for testing as defined in the installation manual. It works fine for amqsput/get of small amounts of data. I turned it over to our programmer and he seems to be getting messages truncated at about 1-1.5k. He is using the supplied MQPUT and MQGET api's. I check to make sure that the MAXMSGL are all set to default 4MB. Not sure what else to check. I did notice if I use amqsblst with a -b of over about 300, the amsqget errors with a 2080, then locks the queue.
Any help is appreciated and thank you for tolerating a noob. |

What programming language is your developer using?
How big a buffer is your developer specifiying on the MQ Get and MQ Put?
What is being specified for the buffer length on the MQ Get and MQ Put?
You both should spend some time reading the Application Programming Guide and the sample programs that are included with MQ. Your developer needs to read it to learn how to write MQ programs, and you need to read it to learn how to fix the code your developer writes, because almost all developers will blame MQ first and not the code...

Thanks for the questions....
My developer states he is using C, with 10000 bytes for the buffers. |

| Programmer came over and said that the MQGET is showing 5500 bytes received, but the buffer is only displaying 1500 bytes........... |

Is the buffer length also being specified correctly?
It's probably best to have the developer compare their code with the sample amq0get0.c and amq0put0.c code supplied with the product (<install_dir>/samp/ on Unix or <install_dir>\Tools\c\samp\ on Windows).

That's what my brain said was true, but I wasn't confident of my brain. So I went and looked at one of our systems... and my eyes saw amq0get0.cbl and extrapolated.
I guess I should have trusted my brain...
