Service Request Processor data instances
When an EJB, HTTP, Java, JMS, MQ, or SOAP service rule is configured to process service requests asynchronously, or is configured to requeue failed service requests for a later execution attempt, service request information is stored as a persistent object in a request queue in the PegaRULES database.
- How to handle the queued service request objects
- Which queue to use
- How many times to run the requests if they fail the first time
- Whether to store the request object with the results of the processing after the processing is finished.
The first execution of an asynchronous service request
occurs in the service requestor, but in a separate background Thread that executes after,
rather than before, the service response is set. Queuing and the
agent are used for the second and subsequent retries, if
configured. Queuing also occurs when configured through a
condition on the
the service rule.

- Service Request Processor - Completing the New or Save As form
Before creating a service request processor, create or identify a service package data instance; the name of the service package becomes the first key part of the service request processor data instances.
- Service Request Processor form - Queuing Options tab
Complete this tab to specify where to store the service request objects supported by this service request processor instance — that is, which queue class to use, and when.
- Service Request Processor form - Dequeuing Options tab
Use this tab to instruct the Pega-IntSvcs agent how to handle the service requests stored in the queues defined on the Queuing Options tab.
