How to create multiple subscribers and producers in a application
Hi,
I want to create 7 producers and 5 durable consumers in my application
connecting to the same broker. I want to use spring Default message listener
container to create consumers and JMStemplate to create producers.
While reading I am confused about how connection factories should be used. I
was going through the posts and question about pooledConenctionFactory. Some
confusion:
1) Can I use "PooledConnectionFactory" for my use case. Would it cause any
trouble if I use durable subscriber and specify maxConnection in
"PooledConnectionFactory" to the required connections(12) ?

Sorry I gave you the wrong info, its the SpringJMSTemplate that uses a
connection per message. So use a pooled or cached connection factory
for that.
As for the consumers I don't think you need a pooled/cached connection.
See

With the DLMC and durable Topic subscribers, don't use a pooled connection -
use one connection. Separate connections per consumer can improve
throughput, but otherwise are not necessary - unless different Client ID's
are being used.

Sophia-
I suggest starting with a single connection per consumer. That model performs well for most applications. You can then look to add multiple consumers on top of a connection (maybe 4 max) and then look to add additional connections to scale consumption.

So should I use different pooled Connection factory for each listener in my
application ? OR should I not at all use pooledConnectionFactory ?
Thanks,

I don’t recommend using the same pool for consumers (especially if you use local or XA transactions). The benefit is pretty minimal, and it can cause issues once you start scaling.
I don’t see pooling being a big boost for the number of total connections you are describing, but it might make configuration management easier.

Hi,
And how should I use pooledConnection factory.
Should I use different pooled ConenctionFactory for each listener and
producer
or should I use only one pooled connection factory with maxConnection to
required number.
I can a see a similar thread

The spring dlmc opens a connection to send a message and then closes the
connection. This puts a lot of load on the broker. Using a pooled
connection factory gets around this by reusing the connections.
