Re: MQ connection(s) from distributed side to Mainframe show Pend ing after server is dropped without dropping Bridge first
From the Intercommunication Guide. MAYBE?? bobbee Heartbeat interval (HBINT) This attribute applies to WebSphere MQ for AIX, iSeries, HP-UX, Linux, Solaris,and Windows systems, and MQSeries V5.1 for Compaq Tru64 UNIX, Compaq NonStop Kernel, Compaq OpenVMS Alpha, and OS/2 Warp, and for WebSphere MQ for z/OS without CICS. You can specify the approximate time between heartbeat flows that are to be passed from a sending MCA when there are no messages on the transmission queue. Heartbeat flows unblock the receiving MCA, which is waiting for messages to arrive or for the disconnect interval to expire. When the receiving MCA is unblocked it can disconnect the channel without waiting for the disconnect interval to expire. Heartbeat flows also free any storage buffers that have been allocated for large messages and close any queues that have been left open at the receiving end of the channel. The value is in seconds and must be in the range 0 through 999 999. A value of zero means that no heartbeat flows are to be sent. The default value is 300. To be most useful, the value should be significantly less than the disconnect interval value. This attribute is valid for sender, cluster-sender, server, receiver, cluster-receiver, and requester channels. Other than on z/OS 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. From: Keith A.

I don't know if this will help, but a long time ago, we had something that sounds vaguely similar (although it was a Solaris system where you have Windows). What we ended up doing is having the dist. side: 1) Send STOP CHANNEL commands to the mainframe telling it to stop the sender channel to the sun side 2) Issue STOP CHANNEL commands for the sender channels on the distributed side. Then at restart: 1) Send START CHANNEL commands to the mainframe telling it to restart its sender channels 2) Issue START CHANNEL for the local sender The only thing you have to watch for is if you WANT the channels to be down and you do a reboot, although that could be scripted around. Since we have no Windows qmgrs, I don't know if you can do something similar, but at least you now got a response :-) Good luck!
