Calling activity
An HTTP connector is called by a connector activity — an
activity with the Activity Type set to
Connect
that applies to a class derived from the Work- base
class. Such activities can be referenced in an Integrator shape
() in a
flow rule.
Connector activities have the following kinds of steps:
- A step that creates a named page for the class that the connector
rule applies to. This page becomes the primary page for the
connector.
- A step that sets property values and input parameter values that
serve as the input for the connector's message sent to the
external application.
- A step that calls the connector rule. This step uses the
Connect-HTTP method. The step page is the primary page of the
connector.
- A step that processes the reply message that the connector rule
receives.
Asynchronous execution by the Pega-IntSvcs agents
To perform HTTP connector processing asynchronously: 5.5
GRP-255
- Create a Connector Request Processor data instance that defines
the characteristics and classes of queued requests. Associate this
data instance with the RuleSet that contains the Connect HTTP
rules.
- On the Service tab of the Connect HTTP
rule, select
queuing
in the Intended for
field and identify the Connector Request Processor created in step 1.
Leave the Response tab blank; it is not
used.
- Update one or more Data-Agent-Queue instances to
ensure that the ProcessConnectQueue agent entry within
the Pega-IntSvcs agent is enabled with an appropriate time
period.
- In the activity steps that execute the Connect-HTTP method, set
the Execution Mode parameter value to
Queue
.
- Test.
Performance Statistics
For information on gathering
performance information about this connector see
Testing Services and Connectors, a document on the
Integration pages of the Pega Developer Network.
Simulation and debugging
You can simulate an HTTP connector when the external system is
unavailable or when you need to test an application but lack a test
environment.
For more information on testing connectors, see Testing Services and Connectors, a document on the
Integration pages of the Pega Developer Network.
