Chapter 5 General Activities Palette : Wait

Wait

Activity

The Wait activity suspends execution of the process instance and waits for a Notify activity with a matching key to be executed in another process instance. The key specified in the Notify Configuration resource specified on the Configuration tab and the Key field of the Input tab creates a relationship between the Wait activity and the corresponding Notify activity.

The same Notify Configuration shared configuration resource must be specified by corresponding Wait and Notify activities so that data can be passed from the process instance containing the Notify activity to this process instance. The schema in the Notify Configuration resource can be empty, if you do not want to pass data between processes.

The Wait, Receive Notification, and Notify activities allow running process instances to communicate. See TIBCO ActiveMatrix BusinessWorks Process Design for more information on inter-process communication.

Configuration

The Configuration tab has the following fields.

Field

Description

Name

The name to appear as the label for the activity in the process definition.

Description

Short description of the activity.

Shared Configuration

The Notify Configuration shared configuration resource that defines a data schema for this activity. See Notify Configuration for more information.

The Notify Configuration resource is required, but the schema can be empty if you do not want to pass data between processes.

Input

See TIBCO ActiveMatrix BusinessWorks Process Design for more information about mapping and transforming input data.

The input for the activity is the following.

Input Item

Datatype

Description

key

string

The key that coordinates a Wait activity with the corresponding Notify. For example, in an order handling process, the order ID might be the key that Wait and Notify use to determine which Wait activity corresponds to the Notify activity.

The key can be an XPath expression, but it must evaluate to a string.

See TIBCO ActiveMatrix BusinessWorks Process Design for more information and examples of choosing the key for Wait, Notify, and Receive.

timeout

integer

The timeout (number of milliseconds) for this Wait activity. If a Notify activity that has a matching key is not executed in this specified number of seconds, the Wait times out and transitions to the next activity.

If no value or if zero is specified in this field, this activity waits indefinitely.

Output

The output for the activity is the following.

Output Item

Datatype

Description

schema

complex

The schema specified by the Shared Configuration on the Configuration tab. This schema is used to pass data from the process instance containing the Notify into this process instance.
