Thank you for your reply.
If I understand correctly, we should use the same client ID for each
client. And, if that is the case, then this has already been tried,
and the result is that every client after the first throws this
exception:
I know that ActiveMQ doesn't support shared subscriptions of any sort so
if you tried this with ActiveMQ you will not get anything to work, and
if it did somehow create a subscription it would not be a valid one.
You would need to use Apache Artemis for shared subscription support as
that has full support for the AMQP JMS mapping. As the specification
states the subscription is named by the subscription name and the client
ID so if you want to share your clients either need no client ID or they
all need the same for the subscription in question.

Hi Tim,
Yes, each client has a unique Client ID. And this has been verified.
However, should the Client ID follow a specific pattern?
That's your problem then, you are creating many uniquely identified
shared subscriptions.
From the JMS specification
"A shared non-durable subscription is identified by a name specified by
the client and by the client
identifier if set. If the client identifier was set when the shared
non-durable subscription was first
created then a client which subsequently wishes to create a consumer on
that shared non-durable
subscription must use the same client identifier."

Hi,
I have stumbled across an issue that I believe is with
Apache.NMS.AMQP
library. I'm using the latest stable version, 2.4.0, for my .NET C#
service
for message handling, with the latest Apache Artemis and Apache
ActiveMQ
message brokers.
Both the web page on Uri Configuration (
https://activemq.apache.org/components/nms/providers/amqp/uri-configuration
)
and the GitHub project (
https://github.com/apache/activemq-nms-amqp/blob/main/docs/configuration.md
)
state that "nms.clientId" should be used in the Connection Uri to
configure
the Client ID.
However, I have found that using "nms.clientId" breaks consumer
functionality for Shared Consumers, who will then receive every
message
in
the topic. And that, excluding the query parameter, allows Shared
Consumers
to function correctly, with each consumer receiving only their share
of
the
messages.
Please also note that if one does not include the parameter in the
Uri
but
instead sets the ClientId on the connection object itself, the Shared
Customer will still not function correctly, having the same issue as
using
the parameter in the Uri.
However, by not including the nms.clientId parameter, a Client ID is
automatically generated, which I guess is why it works correctly.
Nevertheless, it is less than ideal not being able to use my own
Client
ID.
But maybe I'm doing something wrong. Here is some simple example code
using
the nms.clientId parameter that has the issue:
static async Task SharedAsync(string clientId, CancellationToken
stoppingToken)
{
string uri =
$"amqp://localhost:61616?nms.username=artemis&nms.password=artemis&nms.clientId={clientId}";
Are you giving each client the same ID or are they each being assigned
there own unique client ID ?
var connecturi = new Uri(uri);
var factory = new NMSConnectionFactory(connecturi);
using IConnection connection = await
factory.CreateConnectionAsync();
connection.Start();
using ISession session = await
connection.CreateSessionAsync();
ITopic destination = await
session.GetTopicAsync("topic-name");
using var consumer = await
session.CreateSharedConsumerAsync(destination, "sub-name");
while (!stoppingToken.IsCancellationRequested)
{
var msg = await
consumer.ReceiveAsync(TimeSpan.FromMicroseconds(250)) as
ITextMessage;
if (msg is not null)
{
// process message
}
}
}
Thanks,
John
