Event processing

When a file is uploaded, events are posted to the B2Bi application queue immediately. The file is uploaded to the local data center without waiting for being replicated to other data centers.

For event processing to be successful, Cassandra is required in the local data center.

In event processing, protocol traffic is automatically routed to a remote data center if a WebSphere MQ outage occurs on the local data center. Files are not processed more than once. In case of failures, all files are automatically processed.

If event processing fails because the queue manager failed or the WebSphere MQ service failed, the files are processed when the events are resent through the UI or through the eventUtility script. The files are resent to the data center from which the files originated, and the files are then processed.
