Defining a TCP connection for queue sharing groups

To define a TCP connection for a queue sharing group, certain attributes on the sending and receiving end must be configured.

For information about setting up your TCP, see Defining a TCP connection on z/OS.


Send end

The connection name (CONNAME) field in the channel definition to connect to your queue sharing group must be set to the generic interface of our queue sharing group (see Queue sharing groups ). For more details, refer to Use Sysplex Distributor.


Receive on TCP using a queue sharing group

Receive shared channel programs are started in response to a startup request from the sending channel. To do so, a listener must be started to detect incoming network requests and start the associated channel. You start this listener program with the START LISTENER command, using the inbound disposition of the group, or using the operations and control panels.

All group listeners in the queue sharing group must be listening on the same port. If we have more than one channel initiator running on a single MVS image we can define virtual IP addresses and start your TCP listener program to only listen on a specific address or host name by specifying IPADDR in the START LISTENER command. (For more information, see START LISTENER.)
