Is master started correctly ?

[@eshwarnetha2038]

@@LearningJboss Yes.. it started with out any issues..

[@eshwarnetha2038]

I have three agents..

[@LearningJboss]

please double check below points : 1.open master port 9999 at firewall level. 2. check ages should have all interfaces ( public,private,management and unsecure 3. while starting agent mention master ip address.

I don't know if it helps but I had a similar problem and the bug was that I wasn't adding the admin user correctly to the host-controller's host-slave.xml.

Hello dear Mr. Veera. In an environment like the one shown in the video, how can the activemq messaging service be configured using JMS? Thanks a lot.

[@LearningJboss]

Need more clarity please as by default full and full-ha profiles are come up with defeat inbuilt queue configuration

[@CarlosTrujilloAlmeida]

@@LearningJboss, Thank you very much for answering, I have a jboss EAP 7.2 environment in domain mode with a master and two slaves, I am using a full-ha profile.

[@LearningJboss]

perfect, Now tell me what do you want to do ? 1. configure queues/topics ? 2. create queue connection factory to send messages into queue ? 3. queue consumer application development ? 4. queue clustering ?

[@CarlosTrujilloAlmeida]

@@LearningJboss I want to do configure queues create queue connection factory to send messages into queue the application that consumes the queue I have already developed queue clustering Thank you so much for everything

[@glimmer3302]

Hi Veera, Is it mandatory to run application on domain mode on production ?

[@LearningJboss]

No it's not mandatory

[@sureshgaddameddi3858]

Good Video on domain mode. Please share RH-SSO7.3 setup

[@LearningJboss]

Hi sir, I have followed every instruction in this tutorial as well as your session replication with wildfly15. cluster is running ok, but sessions are not replicating. i have tried with my project as well as 3 war files shared by you. every time i turn a server off, application goes to login page. Please help me

[@LearningJboss]

Please check jboss servers are clustered properly by seeing the logs

[@sarbajitbhattacharjee6652]

@@LearningJboss Thanks for the quick response. In log both instances are single member of the cluster. warning: ManagedMulticastSocketBinding was set to 20.00MB, but the OS only allocated 212.99KB

Please share startup logs after deploying war file
