Resolve Name Immediately

If enabled, the Instance Name of the task instance will be resolved immediately at trigger/launch time.

Time Zone Preference

User-defined; Allows you to specify the time zone that will be applied to the task.

Options:

  • – System Default –
    Time zone is based on the value of the Task Time Zone Preference Universal Controller system property: Server or Inherited.
  • Server (xxx)
    Where (xxx) is the time zone ID of the server; time zone is evaluated in the time zone of the server.
  • Inherited
    Time zone is evaluated in the time zone of the Parent Workflow or Trigger / Launch specification in the case there is no Parent Workflow.

Hold on Start

If enabled, when the task is launched it appears in the Activity Monitor with a status of Held. The task runs when the user releases it.

Hold Reason

Information about why the task will be put on hold when it starts.

Virtual Resource Priority

Priority for acquiring a resource when two or more tasks are waiting for the resource. This priority applies to all resources required by the task.

Options: 1 (high) - 100 (low).

Default is 10.

Hold Resources on Failure

If enabled, the task instance will continue to hold Renewable resources if the task instance fails. Renewable resources will be returned only if the task instance status is either Complete, Finished, or Skipped.

Mutually Exclusive With Self

If enabled, the task will not be allowed to run concurrently with itself. Task will not start until the instance that is running finishes. An instance will transition to Exclusive Wait status if it cannot start due to another instance already running. 

Simulate

Specifies if the instance should execute under simulation mode

Override Previous Instance Wait

Specifies whether or not to override the parent workflow's Previous Instance Wait configuration.

This option only applies for an instance running within a workflow.

Options: 

  • No

  • Yes / -- None --

    Regardless of the parent workflow configuration, the task instance will never wait for a previous instance to complete.
  • Yes / Wait for Last

    Regardless of the parent workflow configuration, the task instance will remain in Instance Wait until the most recent prior instance of the same task has completed.
  • Yes / Wait for Last / Same Workflow

    Regardless of the parent workflow configuration, the task instance will remain in Instance Wait until the most recent prior instance of the same task, within an instance of the same workflow, have completed.
  • Yes / Wait for All

    Regardless of the parent workflow configuration, the task instance will remain in Instance Wait until all prior instances of the same task has completed.
  • Yes / Wait for All / Same Workflow

    Regardless of the parent workflow configuration, the task instance will remain in Instance Wait until all prior instances of the same task, within an instance of the same workflow, have completed.

Agent Details

This section contains assorted detailed information about the Agent / Agent Cluster selected for this task.

Cluster

Indication that selecting an Agent Cluster is required and selecting Broadcast, which lets you select a Cluster Broadcast, is optional.  If Cluster is selected, selecting an Agent is not required unless Agent Variable is selected.

Agent

Name of the Agent resource that identifies the machine where the operation will run. If you do not specify an Agent, you must specify an Agent Cluster or Cluster Broadcast.

Agent Variable

Indication of whether the Agent field is a reference field for selecting a specific Agent (unchecked) or a text field for specifying the Agent as a variable (checked). Use the format: ${variable name}. The variable must be a supported type as described in Variables and Functions.
 

Note

When updating multiple Tasks, to change from using an Agent reference to using an Agent variable, you must change the Agent Variable field to Yes and specify the Agent variable in the Agent Unresolved field. Conversely, to change from using an Agent variable to using an Agent reference, you must change the Agent Variable field to No and specify the Agent reference in the Agent field.

Agent Cluster

If Cluster is selected and Broadcast is not selected; Group of Agents, one of which the Controller will choose to run this task (compare with Cluster Broadcast). You can specify an agent cluster in addition to or in place of a specific Agent. If you specify an Agent and an agent cluster, the Controller first tries to run the task on the specific agent. If the Agent is not available, the Controller reverts to the agent cluster. See Agent Clusters for more information.


Agent Cluster Variable

Indication of whether the Agent Cluster field is a reference field for selecting a specific Agent Cluster (unchecked) or a text field for specifying the Agent Cluster as a variable (checked). Use the format: ${variable name}.

The variable must be a supported type as described in Variables and Functions.
 

Note

When updating multiple Tasks, to change from using an Agent Cluster reference to using an Agent Cluster variable, you must change the Agent Cluster Variable field to Yes and specify the Agent Cluster variable in the Agent Cluster Unresolved field. Conversely, to change from using an Agent Cluster variable to using an Agent Cluster reference, you must change the Agent Cluster Variable field to No and specify the Agent Cluster reference in the Agent Cluster field.

Broadcast

Displays only if Cluster is selected; Indication that selecting a Cluster Broadcast is required. Selecting Broadcast hides the Agent and Agent Cluster fields; you cannot select values for them.

Cluster Broadcast

Group of Agents, all of which will run this task (compare with Agent Cluster). If Broadcast is selected for a task, you must select a Cluster Broadcast instead of a specific Agent and/or agent cluster. Each instance of the task running on its own Agent becomes a separate task instance record in the database and displays separately on the Activity Monitor.

Cluster Broadcast Variable

Indication of whether the Cluster Broadcast field is a reference field for selecting a specific Cluster Broadcast (unchecked) or a text field for specifying the Cluster Broadcast as a variable (checked). Use the format:

${variable name}.

The variable must be a supported type as described in Variables and Functions.
 

Note

When updating multiple Tasks, to change from using a Cluster Broadcast reference to using a Cluster Broadcast variable, you must change the Cluster Broadcast Variable field to Yes and specify the Cluster Broadcast variable in the Cluster Broadcast Unresolved field. Conversely, to change from using a Cluster Broadcast variable to using a Cluster Broadcast reference, you must change the Cluster Broadcast Variable field to No and specify the Cluster Broadcast reference in the Cluster Broadcast field.

Credentials

Credentials under which an Agent runs this task. These Credentials override any Credentials provided in the Agent Details for any Agent running this task.

If the user does not have a login shell, add a - character in front of the runtime credentials name. The Controller will provide a shell for that user and strip the - character from the name.

Required if the Agent Credentials Required Universal Controller system property is true. When required, if the Credential is specified as a variable, and the variable resolves to blank, a Start Failure will occur.


Credentials Variable

Indication of whether the Credentials field is a reference field for selecting a specific Credential (unchecked) or a text field for specifying the Credential as a variable (checked). Use the format: ${variable name}.

The variable must be a supported type as described in Variables and Functions.
 

Note

When updating multiple Tasks, to change from using a Credentials reference to using a Credentials variable, you must change the Credentials Variable field to Yes and specify the Credentials variable in the Credentials Unresolved field. Conversely, to change from using a Credentials variable to using a Credentials reference, you must change the Credentials Variable field to No and specify the Credentials reference in the Credentials field.
