Use WLM/DNS

 

Alter the queue manager object to use the correct distributed queueing parameters.

You must set DNSWLM(YES); optionally we 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:

• Run each channel initiator on a different MVS™ image

• Run each channel initiator with a different TCP stack on the same MVS image.

• Have multiple Virtual IP Addresses (VIPAs) on one TCP stack.

• Use the TCP/IP SHAREPORT option to allow the same port to be used for multiple listeners.

See z/OS 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 TCP/IP in a sysplex, SG24–5235, an IBM Redbooks publication, for more information on WLM/DNS.
