Using WLM/DNS

You must set DNSWLM(YES); optionally you can add the name of the group name to be used as a hostname to the DNSGROUP attribute. If you leave the name blank the queue-sharing group name is used.

 ALTER QMGR TCPNAME(TCPIP) DNSWLM(YES) DNSGROUP(MYGROUP)

WLM/DNS does not offer any support for mapping one incoming port number to a different outgoing port number. This means that each channel initiator must use a different hostname, by one of the following methods:

See z/OS(R) Communications Server: IP User's Guide and Commands, SC31-8780 for more information on VIPA.

See z/OS Communications Server IP Configuration Reference, SC31-8776 for more information on SHAREPORT.

See "Redbook: TCP/IP in a sysplex", SG24-5235 for more information on WLM/DNS.
