Use START LISTENER to start a channel listener.
Notes:
1. On UNIX systems, the command is valid only for AIX, HP-UX, and Sun Solaris.
2. On OS/390:
a. This is valid only for channels used for distributed queuing without CICS.
If you are using CICS for distributed queuing, see the MQSeries
Intercommunication manual.
b. The command server and the channel initiator must be running.
c. A total of four listener tasks can be started. These are for TCP/IP and LU62
with dispositions of INDISP(QMGR) or INDISP(GROUP).
d. If IPADDR is not specified, the listener listens on all available addresses.
e. For TCP/IP, it is possible to listen on multiple addresses and port
combinations.
f. For each START LISTENER for TCP/IP request, the address and port
combination is added to the list of combinations upon which the listener is
currently listening.
g. A START LISTENER for TCP/IP request fails if it specifies the same, or a
subset or superset of an existing, combination of addresses and ports upon
which a TCP/IP listener is currently listening.
h. If you are starting a listener on a specific address to provide a secure
interface with a security product, for example a firewall, it is important to
ensure there is no linkage to the other non-secure interfaces in the system.
You should disable IP forwarding and routing from other non-secure
interfaces so that packets arriving at the other interface do not get passed to
this specific address.
Consult the appropriate TCP/IP documentation for information on how to
do this.
3. On OS/400, OS/2 Warp, UNIX systems, and Windows NT, this command is
valid only for channels for which the transmission protocol (TRPTYPE) is TCP.
