Debug Manager (v9011)
 No IP address/port required in the application startup JCL
– Prevents problems where DHCP reassigns client IP addresses
– Once set up for debug, JCL doesn't need to be modified again
 The direction of the debug connection now matches direction of the
RSE connection
– No outbound connection from the z/OS host is required
– Avoids problems where the client machines are behind a router or NAT
 Uses RSE credentials to match a debug sessions to an appropriate UI
 Debug jobs will wait until an appropriate user connects through RSE
