AVEVA Batch Management Events

The AVEVA Batch Management Server is an Event Provider to the ArchestrA Event Services platform, which in turn uses the ArchestrA Service Bus (ASB) for sending and receiving data. The events are primarily related to state changes during the execution of batches. Each event contains an "Event Type" and also relevant context data properties associated with the event type. Events are fired to a local Event Service where they are queued and made available to interested clients. Event clients can connect to the Event Service and poll for new events. The event client can then use the event and its context data properties to perform external/custom actions.

Note: Batch Events are only supported on AVEVA Batch Management Servers where a System Platform 2014 R2 (or later) Platform is deployed. It also requires that the AVEVA Batch Management Components for ArchestrA IDE feature is installed on the Galaxy Repository or Service Repository node. After these prerequisites are met, you must run the AVEVA Batch Management Configurator for the AVEVA Batch Management Server feature and select and configure the Batch Event option.

If the AVEVA Batch Management Server is not configured for the Batch Events option, Batch Events are not available. A warning message is shown from the "InBatchEventServer" component in the ArchestrA Logger. This is normal on systems that do not expect Batch Events to be enabled.

Important: Batch Events do not support guaranteed delivery if exceptional conditions occur. For example, if a Batch Server is powered down, any events that have occurred that have not been fetched by the client will be lost. Also, if a client is not actively polling around the time when an event occurs, it will likely not see the event.
