SUN IMQ topic messages preview

Question

Is there any way to view the messages that reside inside a JMS Topic destiantion?

I've got a problem with messages not being released from Topic destination. The Topic has got 1 producer and 7 consumers and none of them is durable.

Thanks in advance for any suggestions.

Answer 1

After some digging finally found out the answer.

I need to use the following command:

imqcmd list msg -t t -n my_topic -nocheck

where my_topic is the name of my topic destination. After receiving a response like:

Listing messages for the destination
------------------------------------
Destination Name    Destination Type
------------------------------------
my_queue            Topic

On the broker specified by:

-------------------------
Host         Primary Port
-------------------------
localhost    7676

--------------------------------------------------------------------------------------------------
Message #   Message IDs                                                     Priority   Body Type
--------------------------------------------------------------------------------------------------

2           ID:11-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169717    4          TextMessage
3           ID:12-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169720    4          TextMessage
4           ID:13-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169723    4          TextMessage
5           ID:14-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169727    4          TextMessage

I can view Message details with this command:

imqcmd query msg -t t -n my_topic -msgID "ID:9-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169630" -nocheck

which willl print something like:

Querying message:
------------------------------------------------------------
Message ID
------------------------------------------------------------
ID:9-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169630

In the destination
------------------------------------
Destination Name    Destination Type
------------------------------------
my_topic            Topic

On the broker specified by:

-------------------------

Afterwards the message can be deleted with command:

imqcmd destroy msg -t t -n my_topic-msgID "ID:9-AAA.BBB.CCC.DDD(e9:3b:c8:51:8b:75)-58798-1217457169630" -nocheck

Hope this helps someone, someday...

Answer 2

Thanks, it helped me a lot! Is it possible to filter the listed messages by TimeStamp, or any other properties?
