Hi All,
I have an issue with an application unable to get the message from a local queue.
The issue is if we put a message from an organizational application, it reaches the local queue. The receiving application is unable to get the message.
How ever, if the same message is put on directly on the local queue by MQexplorer, the receiving application processes that message.
MQ 6.0
Windows 2003.
Please share your experiences and help me to resolve this issue.
Thanks in advance.

Why not? MQ reason code? Application abend? Flying monkey attack? Rain of trout?
If you want some help, we're going to need some clues. Like what goes wrong, at what stage, in what MQI call.

If you really mean v6.0, you might want to consider applying some maintennce. Not saying that's your problem but it can't hurt.

This is the error log excerpt..
WebSphere MQ was unable to obtain the account details for MCA user ID 'XXXX'.
This user ID was the MCA user ID for channel 'TO.NTEHUBA' on queue manager
'NTEHUBA' and may have been defined in the channel definition, or supplied
either by a channel exit or by a client.
ACTION:
Ensure that the user ID is correct and that it is defined on the Windows local
system, the local domain or on a trusted domain. For a domain user ID, ensure
that all necessary domain controllers are available.

I'll make it clear.
Assume I put a message 'x' on local queue of a queue manager from application 'A'. The receiving application 'B' will not get the message.
but if I put the same message 'x' on the same local queue of a queue manager from MQexplorer application , the receiving applicatin 'B' is able to read that message and process it.
This is the issue. I've attached the error log excerpt in my previous post.
Thanks,
Vinay |

Well that seems fairly self explainatory.

How is appln A connecting to the queue manager? Is it in client mode? If then it should be using a channel. That channel could have a mcauser XXXX which your windows environment is not able to recognize.
Are your sure the MQPUT from application A really reaches the Q for B to consume? Your initial post says so..but to confirm  |

Yes, application 'A' connects using a webSphere MQ client. Client version is 6.0. It uses a server connection channel. However, in the channel properties in MCA, there is indeed a user 'XXXX'.
MQPUT from application 'A' reaches the local queue. The 'curdepth' of the local queue increases as soon as the message is put from 'A'.
My doubt is, why is the application processing the message from MQexplorer and not from the MQclient.
MQexplorer and MQclient (Application 'A') are on Server1.
Application 'B' is on Server2.
Regards,
Vinay |

How is MCA user ID 'XXXX' defined on 'NTEHUBA'? How long is the ID?
btw, if I am not mistaken, you mentioned application B is on another server (say server B), then how can application B on server B get messages from a queue on server A? |

when I check the channel properties - MCA : I literally see 'XXXX' as the user id.
there are two servers.
Application 'A' puts the message to an alias queue on Server 'A'.
This alias queue resolves to a remote queue on Server A.
The remote queue on Server 'A' points to a local queue on Server 'B'.
Application 'B' connects to Server 'B' local queue to get the message for processing.
This is the MQ setup.. |

And what are the odds that user 'XXXX' does not exist? That looks like a null user to me.

Are you getting the above MQ exception in server B or Server A?
Is there any application exception for appln A or B?
What type of channel is TO.NTEHUBA ? |

Implies a SDR...and I still think that user 'XXXX' is a null user, same as 'NOBODY'.

If the user is a null character string, why is application 'B' processing the messages when put from MQexplorer on Server 'A'.
Even now, the MCA user is XXXX. There is no change made to the configuration. |

So what you're saying is that if you put a message onto a remote queue definition on server A using MQExplorer, the message travels to the local queue on server B where it's processed. If you put it using a client app it doesn't travel to B and you get an error saying the non-existant MCA User can't be verified?
Do I have that right? Do you still not see the problem?
