Hi,
We have a sdr/rcvr channel pair defined b/t a Solaris and an OS390 mq servers. Can anybody share how do the MCAs negotiate HBINT, if they are not defined the same on both sides?
Thanks. |

You can find this in the MQSC Command Reference...

| The value that is used is the larger of the values specified at the sending side and the receiving side. |

Extracted this from the MQ intercommunication book:
"For client connections, heartbeats are only flowed from the server when the client issues an MQGET call with wait; none are flowed during other MQI calls. Therefore, you are not recommended to set the heartbeat interval too small for client channels. For example, if the heartbeat is set to ten seconds, an MQCMIT call will fail (with MQRC_CONNECTION_BROKEN) if it takes longer than twenty seconds to commit because no data will have been flowed during this time. This can happen with large units of work. However, it should not happen if appropriate values are chosen for the heartbeat interval because only MQGET with wait should take significant periods of time." |

Additionally...
The HBINT on a client channel defined using the MQSERVER method is the default, 300, so that is the initial negotiation value on the client.
If one of the other methods, MQCONNX with an MQCD structure, or the client channel method, is used, the initial value is the value from the channel definition. |
