Hi,
Environment 1
- Windows Server 2008 R2 Standard
- Message Broker 7 (Ver 7.0.0.0)
- Websphere MQ 7.0.1.10
Environment 2
- OS400
- Websphere MQ 8.0.0.0 (Level p000-140429.1)
1. The AS400 environment was upgraded from Websphere MQ 7 to Websphere MQ 8
2. Since the upgrade, GROUP messages sent from the windows server (using the message broker) ends up on the AS400 queue manager in format MQHMDE instead of MQSTR.
3. There seems to be header data preceding the data portion of the message but making it part of the data
4. The trace below is immediately after the messagebroker writes the message out to the Windows remote queue which points to the AS400 queue

SET OutputRoot.MQMD.MsgFlags = MQMF_LAST_MSG_IN_GROUP;
SET OutputRoot.MQRFH2 = NULL;
SET OutputRoot.MQMD.Format = MQFMT_STRING;
SET OutputRoot.MQMD.GroupId = InputRoot.MQMD.MsgId;
SET OutputRoot.MQMD.MsgSeqNumber = cntTotRecs;

Any ideas on what needs to change to avoid the MQHMDE header to be added or for the AS400 Ver 8 queue manager to avoid making group messages header info part of the actual data part of the message?

Can you define more specifically what you mean there?
Have you heard of the header chaining concept?
What exactly are you trying to do?
Maybe you need to set the MQMD-VersionId? to current version before sending on windows...

The Version on the MQMD is set to 2.
| Code: |
(0x03000000:NameValue):Format = 'MQSTR ' (CHARACTER)
(0x03000000:NameValue):Version = 2 (INTEGER)
(0x03000000:NameValue):Report = 0 (INTEGER) |
This is a simple group message that's being sent using a message broker from a windows ( MQ Ver 7 ) to an AS400 ( MQ Ver 8 ) environment. It's been running forever without any issues.
The only change within this environment is that the AS400 use to be on MQ ver 7 and was upgraded to MQ ver 8.
This issue only happens on group messages since the MQ ver 8 upgrade on the AS400. Even though the message has a the MsgFlags = 16 when it's sent from the broker, when I view it in the explorer on the AS4000 queue manager it shows on Segmentation "Segmentation inhibited, None" which implies it somehow landed that side as a normal message (not part of a group).
Below is the way that the AS400 interprets the data. However the actual data sent starts from "DDIS". Hence I suspect the part before "DDIS" is header information which is erroneously made part of the data when it hits the Websphere MQ Ver 8 AS400 Queue Manager
Using rfhutilV7 give exactly the same result with group messages. This is purely a Webshpere MQ issue

Is there perhaps a setting or configuration change required on the AS400 which might prevent this. A PTF to be applied?
I hope this points out a bit better the problem which I'm experiencing.

Did you open a PMR? If not do so.
I figure that what you have is a chained header.
Please do not use a static constant like 2, use something like MQMD_CURRENTVERSION ...

I'm actually not using a static constant. The value 2 merely appears in the trace file when the data is written to the file system after the constant MQMD_CURRENTVERSION was translated to a value.
I've tested data using RFHUtil and got the same results.
The AS400 administrator will open a PMR soon.
