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.
The value is one of the following:
- 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.
