Dear OS-Team,

after upgrading to yuuvis7 our core-service.log prints following error:

2021-07-07 16:31:28,362 ERROR [org.apache.camel.component.jms.DefaultJmsMessageListenerContainer] (WorkerQueueProcessorThread-1) Could not refresh JMS Connection for destination 'BPMWORKERQUEUE' - retrying using FixedBackOff{interval=5000, currentAttempts=104, maxAttempts=unlimited}. Cause: Error while attempting to add new Connection to the pool; nested exception is javax.jms.JMSException: Could not connect to broker URL: tcp://127.0.0.1:61616. Reason: java.net.ConnectException: Connection refused: connect

We were updating the applicaton-mq.yml based on our understanding of https://help.optimal-systems.com/yuuvis_develop/display/onpremise/How to upgrade to yuuvis RAD 7.0

There are some misunderstanding about the messaging-service. Based on the documentation, we assume the messaging-service is the microservice "Messaging" in spring boot admin and therefore installed on the service-manager (not on core-service).

Following setup do we have:

core-service (separate machine)
service-manager (separate machine; Ports 61616 and 61777 are open)

application-mq.yml

spring.activemq.broker-url: 'tcp://127.0.0.1:61616'
spring.activemq.broker-url-stomp: 'stomp://127.0.0.1:61777'
spring.activemq.in-memory: false
spring.activemq.pooled: true
spring.jms.pubSubDomain: true

Result: All microservices using the "Messaging" microservice are happy. But core-service is trying to connect to 172.0.0.1:61616. Do we have to set a configuration on the core-service in order to solve this Connection error?

If we change the application-mq.yml to set the ip of the core-server, than the service-manager.log will throw errors because the custom-microservices cannot connect to the messaging-server.

if we change the application-mq.yml to set the IP or hostname of the service-manager, the service-manager.log will throw Connection Refused errors, even though its his own IP.

Thank you for your help,

Dennis

Hello Dennis,

you need to put the public IP address of the service-manager server in the application-mq.yml.

Thanks Nicolai, your info helped. Now it's working.
It would be good if it could be written like that in the documentation :)
