Executing an Integration Process
After you define an integration process, including process steps and logged fields, you can create running instances of the integration process.
The following example shows how you might use the pub.monitor.integrationProcessLogging services to create and execute an instance of an integration process that you have already defined.
Note: Although you can view information about integration processes using Monitor, integration processes are not eligible to be stopped, suspended, resumed, or resubmitted.
Executing an Integration Process
The following table describes how to create and execute an instance of an integration process.
Flow
Description
1.
Each process requires a unique process instance ID. You can create one on your own or use the pub.monitor.integrationProcessLogging:generateProcessInstanceID service to generate a unique process instance ID.
Note: This service does not add data to the Process Audit Log database. That is, it does not start a new instance of the integration process.
2.
To log a running instance of an integration process, create a process instance. To create a new process instance, invoke the pub.monitor.integrationProcessLogging:createProcessInstance service.
As input to this service, you must identify the process definition for which you are creating the instance. The process definition must already exist in the Process Audit Log database, which you add using the pub.monitor.integrationProcessLogging:createProcessMetadata service, as shown in the sample in Defining an Integration Process.
After you create the process instance, its process status is Started. Use the pub.monitor.integrationProcessLogging:updateProcessInstanceStatus service if you want to change the process status.
3.
To start logging information about the first step in the integration process, create an instance of the first step. To create a step instance, invoke the pub.monitor.integrationProcessLogging:createStepInstance service. As input to this service, you identify:
*The process instance in which the step is running. Specify the same process instance ID that you specified as input to the pub.monitor.integrationProcessLogging:createProcessInstance service in the previous INVOKE flow operation.
*The step definition for which you are creating the instance. The step definition must already exist in the Process Audit Log database, which you add using the pub.monitor.integrationProcessLogging:createStepMetadata service.
After you create the step instance, the step status is Started. Use the pub.monitor.integrationProcessLogging:updateStepInstanceStatus service if you want to change the step status.
4.
After the step instance is logged, execute the service(s) for the first step of the integration process. The next flow operations are based on the outcome of this step.
5.
This series of flow operations shows the logic you might perform when a step fails:
*The step status is set to Failed using the pub.monitor.integrationProcessLogging:updateStepInstanceStatus service.
*The process status is set to Failed or Failed (Escalated) using the pub.monitor.integrationProcessLogging:updateProcessInstanceStatus service.
*An error message is logged for the process using the pub.monitor.integrationProcessLogging:createProcessError service.
*A service you create is invoked to exit the integration process.
6.
This series of flow operations shows the logic you might perform when a step is successful:
*Values are set for logged fields that are associated with the step using the pub.monitor.integrationProcessLogging:createLoggedFieldInstance service.
*The step status is set to Completed using the pub.monitor.integrationProcessLogging:updateStepInstanceStatus service.
7.
This series of flow operations handles the second step in the integration process. The flow operations are similar to those described above in steps 4, 5, and 6.
8.
This series of flow operations handles the third step in the integration process. The flow operations are similar to those described above in steps 4, 5, and 6.
