A concurrent workflow is a workflow that can run as multiple instances concurrently. A workflow instance is a representation of a workflow. When you configure a concurrent workflow, you enable the Integration Service to run one instance of the workflow multiple times concurrently, or you define unique instances of the workflow that run concurrently.
Configure a concurrent workflow with one of the following workflow options:
Allow concurrent workflows with the same instance name.
Configure one workflow instance to run multiple times concurrently. Each instance has the same source, target, and variables parameters. The Integration Service identifies each instance by the run ID. The run ID is a number that identifies a workflow instance that has run.
Configure unique workflow instances to run concurrently
. Define each workflow instance name and configure a workflow parameter file for the instance. You can define different sources, targets, and variables in the parameter file.
When you run concurrent workflows, the Workflow Monitor displays each workflow by workflow name and instance name. If the workflow has no unique instance names, the Workflow Monitor displays the same workflow name for each concurrent workflow run.
The Integration Service appends either an instance name or a run ID and time stamp to the workflow and session log names to create unique log files for concurrent workflows.
