Actions that Run-Time Policies Can Execute
A run-time action is a single task that is included in a run-time policy and is evaluated by webMethods Mediator. Actions in run-time policies perform tasks such as identifying and validating consumers, traffic management and logging transaction activity. You specify actions when you define the policy.
CentraSite provides run-time action templates. A run-time action template is a definition of an action that can be used in a run-time policy. Most action templates specify a set of parameters associated with a particular policy action. For example, when you configure the Evaluate WSS Username Token action you use an identifier (for example, a WSS username token) to identify and validate the consumers who are trying to access the APIs. You can include multiple actions in a single policy.
Built-in Actions
CentraSite includes many built-in actions that you can use to compose run-time policies. Built-in actions are provided in the following categories:
Category | Description |
Logging and Monitoring | Actions that monitor and collect information about the number of messages that were processed successfully or failed, the average execution time of message processing, and the number of alerts associated with an API. |
Security | Actions that enforce identification and validation of the consumers who are trying the access the API. |
Traffic management | Actions that limit the number of service invocations allowed during a specified time interval, and send alerts to a specified destination when the performance conditions are violated. |
Validation | Actions that validate all XML request and/or response messages against an XML schema referenced in the WSDL. |
For information about the built-in actions that CentraSite provides for run-time policies, see Run-Time Governance with CentraSite .
Custom Actions
If you need to execute a task that is not provided by a built-in action, you can create a custom action to perform the work. CentraSite offers the functionality to implement custom computed actions with your own algorithms using the GWT framework. For information about adding custom actions to CentraSite, see Run-Time Governance with CentraSite .
