Activities
Activities are the individual units of work in a process.
Activities generally interact with an external system and perform a task. Activities that perform similar tasks are grouped in an entity called a palette. TIBCO Business Studio for BusinessWorks provides various technology-specific palettes using which you can build a business process.
Each activity in a palette is represented by an icon.
For example, the
JDBC Update activity is represented by the

Activities can be classified into three types:
- Regular Activities perform a specific task. Regular activities can have input and output in addition to their configuration. Activities can also state the faults they can generate at runtime. This allows the process to be designed to handle these faults and perform the necessary actions. Regular activities can be further classified into synchronous and asynchronous activities.
Synchronous activities are blocking. They block the execution of the process until the activity task completes.
Asynchronous activities are non-blocking. They perform a task asynchronously without blocking the execution of a process.
- Process Starter Activities are configured to react to events. They trigger the execution of a process when the event occurs. Process starter activities can have only outputs in addition to their configuration. For example, the HTTP Receiver process starter activity starts a process when an HTTP request is received.
