2.2.3 Shutting Down the Handler
When the network connection is lost, the Handler process automatically shuts down. The next service request sent causes the Listener to automatically start a new Handler, if necessary.
Use the supplied shutdown transaction BDWN to
terminate active TMA TCP for CICS programs. Depending on the
options specified, this causes all Handlers to shut down
gracefully. The name of the BDWN transaction may have
been changed at your site during installation, so verify the
name.
