Hi All, Further to the investigation done to support coordination=false in MT mode, following is implemented.
With coordination=false inbound endpoint will not schedule any task, but run as a background thread. When starting the ESB, if there is a task scheduled tenant gets loaded automatically. Since we are not using tasks for inbounds in this case tenant won't get loaded. Solution:- When tenant creates a polling inbound endpoint this will make a entry in the config registry. (Similar to listening inbound). At the server start-up if there are such tenants (With polling inbound) will be loaded problematically. Since we are getting the tenant context in each execution cycle tenant will not get cleaned up.
