GRAVITY Process Invocation

Supported Process Trigger Types

The system includes the following built-in trigger types and start modes:

• Manual – the process is launched manually from the project configuration window.
• From another GRAVITY application – a project can contain operators that invoke another application during processing.
• Scheduler – starts a project based on a time-based scheduling mechanism.
• Database – starts a project in response to an event occurring in a database.
• File – starts a project when a new file appears in a specified directory.
• WebService – starts a project via a REST API call.
• RabbitMQ – starts a project upon receiving a message from the RabbitMQ server.
• Event – starts a project when a specific event occurs in the GRAVITY environment.
• Socket – starts a TCP server on a defined port; when a client sends a message to the server, the project associated with the trigger is launched.
• AS2 Server – runs an AS2 server that enables receiving and automatically processing EDI documents from defined business partners.

The configuration of automatic triggers is available in GRAVITY.exe under the TRIGGERS tab. Each trigger starts a single project unless that project uses another one — in such a case, the project is additionally invoked by another GRAVITY application.

Before using automatic triggers, make sure to review the Automatic Invocation Server section.

Triggers may be subject to execution queuing rules. These rules are described in the Managing GRAVITY Process Queues section.
