WebSphere and WebMethods Broker Connectivity Lost

Hi,

We are using webMethods broker as JMS provider and MDBs on WebSphere application server are consuming the messages from WM Broker’s queues. All the setup works and JMS communications works as expected. The issue we are seeing is, whenever WM Broker is down(these are scheduled outages for maintenance), we had to restart the WebSphere application server as websphere is unable to reconnect to WM Broker. Is there any settings/configuration on websphere or WM broker side to make the Websphere->WM Broker connection establish again without the need of restarting the Websphere application Server?
