This section describes possible problems with an HTTP or HTTPS connection and provides guidance on how to handle them.
The consequences of a server or broker failure in an (HTTP or HTTPS) connection vary depending on the specific component that has failed:
If the application server or Web server fails and is restarted, all existing connections are restored with no effect on clients.
If the broker fails and is restarted, an exception is thrown and clients must reestablish their connections.
In the unlikely event that both the broker and the application server or Web server fail and the broker is not restarted, the application server or Web server will restore client connections and continue waiting for a broker connection without notifying clients. To avoid this situation, always restart the broker after a failure.
If an HTTPS client cannot connect to the broker through the tunnel servlet, do the following:
Start the tunnel servlet and the broker.
Use a browser to access the servlet manually through the tunnel servlet URL.
Use the following administrative commands to pause and resume the connection:
imqcmd pause svc -n httpsjms -u admin imqcmd resume svc -n httpsjms -u admin
When the service resumes, an HTTPS client should be able to connect to the broker through the tunnel servlet.
