Hi
I am writing a program in Cobol( CICS/Mainframe environment) to read, Process and Write messages to the Queue. While writing a message greater than 4,193,876 bytes, I am getting a message code of 2030. I need to be able to write approximately 5 MB. The Systems people have let me know that they have increased the size of the Queue as 5,450,000 and the Queue manager as 104,857,600 bytes.
I understand 4 MB was the limit in an older version. They say there are other applicaions which are able to write more than 5 MB of data.
Can anyone tell me what is the problem? Is there any additional Parm or setting to be done other than increasing the MAXMESGL of MQ?

If the queue is a remote queue, you are really putting to the transmission queue so you need to check the MAXMSGL of that and the sending and receiving MCA's, and of course the receiving QMgr.
If you are putting via an alias queue, you need to specify the MAXMSGL on the alias too.
Apart from that, what you are attempting is well within MQ's capabilities, suggesting your program is not behaving quite as you intend?

Also make sure your Dead Letter Queue is set to handle the larger messages.
Also if you are using a Client connection make sure your SVRCONN channel has the proper MAXMSGL set.
