When you build and upload a subscription triggered process, Process Engine uses the default Integration Server connection alias, based on the message provider configured in Integration Server. The default connection alias for webMethods Broker (deprecated) is IS_BROKER_CONNECTION. The default connection alias for Universal Messaging is IS_UM_CONNECTION. When you change the default connection alias, you must reload the WmPRT package in Integration Server Administrator.

When you create a custom IS connection alias, you must set it as the default connection alias. Process Engine always uses the default IS connection alias.
