Hi,
We are uisng MQ,MQ Link for R/3 in a SAP project. The message transfer is between SAP (on AIX) and Mainframe(OS/390).The files(IDOCS) go both ways.When the file size is BIG it is not uploading from SAP(AIX) to MVS.When the file is big the messages are put in DEADLETTER QUEUE.
The BIG files come once in a while.
How to transfer BIG files.What changes i have to make for this.
Thank you
Raj  |

Hey Raj-
Well, let me list some of the questions which may or may not be relevant-
1. What is the purpose of connecting SAP R/3 with the Mainframe systems?.
2. How are the IDocs transferred to the mainframe systems data structure. I mean how are you parsing IDocs to the legacy data structure (using developer tool?. If so then does IDoc domain exist like MRM ?).
3. How many mssg. flows are involved in doing the transformation?.
4. How frequently are the trigger monitors run to invoke the application on the legacy sys?.
I hope I am not irritating you.
Coming to your question how abt segmenting the big files logically?. Thanks.
Cheers,
Maha |

What is the reason code on the messages when they are in the Dead Letter Queue?
What does the manual say about that Reason Code?
What properties of queues and queue managers are you aware of that have anything to do with the size of a message?
What MQSeries objects are involved in moving the message between the AIX machine and the OS/390 machine?
Have you searched here for 'large messages' or for the Reason Code being given?

Well if the file is bigger than 4mb, which is the default max message size
1) Change the max Message Length on the xmitq, and the destination queue on the mainframe. You also have to change the channel definitions
max message length on both sides SDR/RCVR. MAX size is 100mb
assuming you have I think MQ V5.2 or greater.
