Funny - I'm sure I remember reading this on one of IBM's Hints and Tips web pages (a long time ago). Still, I can't find it now so I'll just have to put it down to old age! But Paul's explanation was very clear so thanks for asking the question.

Heartbeat is valid for recievers. The below is from the Intercommunication Handbook. <Quote> HeartBeat This attribute is valid for sender, cluster-sender, server, receiver, cluster-receiver, and requester channels. Other than on OS/390 and OS/400, it also applies to server-connection and client-connection channels. On these channels, heartbeats flow when a server MCA has issued an MQGET command with the WAIT option on behalf of a client application. <End Quote> Peter Potkay IBM MQSeries Certified Specialist, Developer [EMAIL PROTECTED] X 77906 -----Original Message----- From: Paul Meekin [mailto:[EMAIL PROTECTED]] Sent: Monday, December 02, 2002 11:34 AM To: [EMAIL PROTECTED] Subject: Re: Keep Alive vs Heartbeat - What's the diff? If I remember correctly, Heartbeat only works for Sender channels, keepalive only works for receivers.
