Orchestrating
Orchestrate anything with HCL Universal Orchestrator.
- Orchestration CLI commands
  You can use the various command options in Orchestration CLI to achieve specific results. The command options are not case sensitive and you can use either uppercase or lowercase letters.
- Workflow definition
  A workflow is a set of tasks to be run, together with times, priorities, and other dependencies that define the processing order.
- Task definition
  A task definition is a unit of work that specifies an action to be performed on specific workstations in the HCL Universal Orchestrator network.
- Event source definition
  An event source is an item that allows HCL Universal Orchestrator to receive events from specific event plug-ins.
- Calendar definition
  Calendars define the days in which workflows do or do not run.
- Folder definition
  You can use folders to organize your items accordingly to your business needs.
- Credentials definition
  Credential definitions are used to store user IDs and passwords, or tokens.
- Variable table definition
  Variables are values that can change according to the purpose of workflows and task templates.
- Workstation definition
  A workstation is a scheduling item that runs tasks.
- Resource definition
  A resource is an item that represents a quantifiable asset, measured in terms of units. You can add resources as dependencies in tasks or workflows.
  - Managing a resource definition from the Orchestration CLI
    You can run the new command to create a resource. Configure the mandatory and optional parameters to create a unique resource.
  - Managing a resource definition from the UI
    You can create a new resource and add it to tasks or workflows using the UI.

Resource definition

A resource is an item that represents a quantifiable asset, measured in terms of units. You can add resources as dependencies in tasks or workflows.

You can specify any positive integer as resource units and then allocate these units in tasks or workflows. Tasks or workflows that are dependent on the availability of a certain amount of resource units only run when the specified number of units is available.

For example, if you create a resource definition with quantity as 10 units and allocate 5 units to a task, you can run only two instances of that task simultaneously, since a single run needs 5 units of the resource. If you want more instances of the task to run simultaneously, you must either increase the quantity of the resource or decrease the quantity of units specified in the resource dependency of the task. The amount of resource units defined in resource dependencies is not limited by the maximum amount of available resource units. Task or workflow definitions that do not meet their resource dependency requirements are put in HOLD status until the required amount of resource units becomes available.

Note: If you define resources for a subflow task, they override the resources specified for the workflows nested within the task, if any.

Resource definitions can be managed from the Orchestration CLI and from the UI.
