Hi,
I just need to see the message content(msg browse) when the queue(local) is inhibited. The purpose would be to delete it if the content is not the one as I expect.
Now why the queue is in inhibited state is that an application is listening to it. So if I enable the queue I cannot see the message. This is just for testing and not the case for a real time app as it is not a proper way I guess.
Experts: In case, this topic is already discussed, please give me the link.
Thanks, |

Why dont you stop the application from listening and then perform your analysis? (i'm assuming you can stop the message processing interface easily enough as I'm used to working with WAS interfaces. Extra information would be useful of course!).
AFAIK there is not way to read a message when the queue is get inhibited. |

if a queue is get inhibited there can't be an application active listening for messages on that queue. it would receive get-inhibitet too like you do. or is it just ignoring that fact and is retrying over and over?
if the queue is get inhibited to prevent a trigger from being generated then you coulds switch triggering off, and in a second step get enable the queue and perform your checks.
and like WMBDEV1 i also think there is no way to get your hands on the message content of a get inhibited queue.

One way to accomplish this is to define a queue alias, with queue local as target queue, and get-inhibit the queue alias. Apps that open the queue alias can't get/browse messages, but apps that open the queue local can. |

Exactly what error message did you observe when you attempted to browse the queue?
Are you sure that the queue is get-inhibited? Did you do an mqsc DISPLAY QLOCAL command?
Perhaps the queue was opened EXCLUSIVE. This would prevent a 2nd app from opening the queue.

This is a test I am making on a QL. Just need to know if its possible to read(see the content of) a msg in the get-inhibited queue.
Thanks, |

Nope.
(as you are doing some local test, leave get(enabled) on the queue and then read the queue and see msg contents using amqsget / amqsbcg / MO71 )

Note that amqsget has a limited buffer size (64Kb in V7.0?) and will regard a truncated message as a failure, and is a destructive-read sample, so maybe not the best thing to advise in this circumstance.

Its a kind of 'test' that's why its an option to test for small msgs to get destructively and see its content. ( I presumed he gonnu test for small messages, but I agree with you exerk on the fact with amqsget )
Go to Infocenter , search "Features demonstrated in the sample programs" , click on the result of that search ! There you can see many 'test' options.

I understand those points. But the fact is that (As I said in my first post of this topic) the queue which I am talking is being listened by another app (and I wanted to test in that way).
So I need to read a msg without stopping that app. |

So you would want to use the Browse sample rather than the Get sample.
But you can't guarantee that a) the other app hasn't opened the queue for exclusive get, b) that the message you want to Browse hasn't been consumed by the other app first. |

| And thats why I said I want to browse(in other words read) the msg when the queue is inhibited. If the queue is enabled then the msg would not stay in the queue for even a millisecond and would be consumed by the app. |

Yes.
But you can't do that either. |

Between applications MQ is configured to transport the msgs (simple distributed scenario).
Application teams are generally concerned about the payload of the msg. If they are receiving it then why don't you ask them to give you the payload of the msg (if its a 'test' msg).
If the msg is not perfect as it should be for the target appl. then target appl. should raise that concern by pointing out whats missing/extra in that msg.
