Server and Trigger Properties that Affect Transient Error Handling During Trigger Preprocessing
Overview of Transient Error Handling During Trigger Preprocessing
Trigger preprocessing encompasses the time from when a trigger first receives a message (document) from its local queue on Integration Server to the time Integration Server invokes the trigger service. Transient errors can occur during this time. A transient error is an error that arises from a temporary condition that might be resolved or corrected quickly, such as the unavailability of a resource due to network issues or failure to connect to a database. For example, if a document history database is used for exactly-once processing, the unavailability of the database may cause a transient error. Because the condition that caused the trigger preprocessing to fail is temporary, the trigger preprocessing might complete successfully if Integration Server waits and then re-attempts trigger preprocessing. To allow the preprocessing to complete successfully, Integration Server provides some properties and settings for transient error handling.
Note:
The transient error handling for trigger preprocessing applies to webMethods messaging triggers and JMS triggers. It does not apply to MQTT triggers.
