Hi,

We are migrating from WMB V7 to IIB 9 and we are planning to implement Multi Instance broker feature for HA and Failover functionality. We have two servers. On first server, we have Integration Node INODE1 and QM (INQM1) and the corresponding standby instances (INODE1, INQM1) are running in standby mode on second server. Similarly, we have Integration Node INODE2 and QM, INQM2 on second server and the corresponding standby instnces are running on server1. And the broker queue managers are in cluster. I would like to test the failover functionality when one of the servers goes down while the flow on one of the servers is in the middle of processing the message that came to the flow. Consider that a flow is running on INODE1 and is doing some processing on the message that it consumed (from a queue or through http conenction). If the flow has to make a DB call to update some data in DB and subsequently call a Web Service to send this info about the DB update. If after the DB update is done and while calling the web service to send this update info, serevr1 goes down which means the flow running on INODE1 was in the middle of calling the web service. As we have the passive instance of INODE1 on second server, will the processing of message (in this case, calling the web service be resumed when the passive instance of INODE1 running on second server comes up?
