  • Patent number: 11238386
    Abstract: Techniques are described for workflow management, including automatically deriving characteristics of a user task node in a workflow based on an analysis of other workflow elements such as conditional sequence connectors. In some implementations, elements of a workflow presented in the modeler user interface of a workflow management platform are analyzed, and element(s) of the workflow are automatically and dynamically modified based on the analysis. For example, a workflow may include a first user task that is connected to subsequent node(s) in the workflow, such as other user task(s) downstream from the first user task. The first user task may be connected to each subsequent node by a conditional sequence connector. The condition information for each connector can be extracted from the workflow information and used to automatically modify the first user task to include decision branches for each element of condition information extracted from a respective connector.

  • Patent number: 10904238
    Abstract: Techniques are described for managing access tokens in a computing environment. A proxy service can be configured to issue a first token to a workflow engine, the first token having a substantially unlimited lifetime to not time out during the workflow duration. The first token may be provided to the workflow in place of a shorter-lifetime token that may have otherwise been requested from a backend service. The first token may be used by the workflow engine to provide authorization for operations of the workflow. On completion of the workflow, the workflow engine may send an indication to the proxy service to request interactions with the backend service. The proxy service may request a second (e.g., limited-lifetime) token from the backend service, and use the second token to interact with the backend service on behalf of the workflow, thus acting as an intermediary between the workflow and the backend service.

  • Patent number: 9721230
    Abstract: In a first method, a developer mode is determined when a workflow template patch is received, and execution of new workflow instances is either blocked or permitted, or continued execution of workflow instances is forbidden. In a second method, parallelization of workflow execution is provided in an in-memory database management system. In a third method, after received user privilege information, database records associated with a workflow are determined and stored for use at workflow instance runtime. In a fourth method, artifacts used by a workflow are identified using a workflow template. When a command to execute a workflow instance is received, information is stored for generating instances of artifacts for use during execution of the workflow instance. In a fifth method, for a workflow template to be inactivated, the associated workflow template is suspended after currently executing workflow instances have completed and job executors have acknowledged a suspending state.
