Subject [jira] [Commented] (AMQ-5732) Changing message selector leads to blocking message
Date Wed, 22 Apr 2015 05:50:59 GMT


Cadmean commented on AMQ-5732:

It is indeed what I want to achieve using ActiveMQ as a small database. The reason is that
all the clients (consumer) are always active. In this case, I use activemq broker to save
the file location (blobmessage) in a fileserver I build. If a client needs any file, they
just need to create a session and receive the blobmessage. 

Since I am not sure if the problem is caused by xml configuration, I am going to setup a new
broker and see if this problem exists.

>                 URL:
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker, JMS client
>    Affects Versions: 5.11.1
>         Environment: Suse Linux 11 sp2
>            Reporter: Cadmean

> The problem is:
> 1. I create a queue in activemq broker (version 5.11.1) and some message with string
property, for example "filename".
> 2. Use a client to consume the message with message selector "filename='123.tar'" with
consumer.receive(),it works.  After it receive the message, it acks the message and send the
same message back to the broker and commit the session. (client_acknowledge). 
> 3. Use the same client, change the message selector to "filename='456.tar'" with consumer.receive(),
the consumer is blocked. 
> 4. restart the broker and consumer "filename='456.tar'" again, it successfully receive
the message, but if i change the selector back to "filename='123.tar'", it blocked again.
> At first I thought that there might be some rules for message dispatching. However, with
ActiveMQ version 5.10.0, the problem is gone.
