TCPStackType (MQLONG)

This specifies whether the channel initiator can use only the TCP/IP stack specified in TCPName, or can optionally bind to any selected TCP/IP stack. This parameter is only applicable in CINET multiple stack environments.

MQTCPSTACK_SINGLE

The channel initiator can use only the TCP/IP address spaces named in TCPName. This is the default value.

MQTCPSTACK_MULTIPLE

The channel initiator can use any TCP/IP address space available to it. It defaults to the one specified in TCPName if no other is specified for a channel or listener.

This attribute is supported on z/OS® only.

To determine the value of this attribute, use the MQIA_TCP_STACK_TYPE selector with the MQINQ call.
