Before You Begin

The Linux/Unix task allows you to run a platform-specific application on a Linux/Unix machine. To run a Linux/Unix task, you must first complete the following tasks:

Built-In Variables

The following built-in variables can be used in a Linux/Unix task to pass data where appropriate:

Creating a Linux/Unix Task

Step 1

From the Automation Center navigation pane, select Tasks > Linux/Unix Tasks. The Linux/Unix Tasks list displays a list of all currently defined Linux/Unix tasks.
 
To the right of the list, Linux/Unix Task Details for a new Linux/Unix task displays.
 

Step 2

Enter / select Details for a new Linux/Unix task, using the field descriptions below as a guide.

  • Required fields display an asterisk ( * ) after the field name.
  • Default values for fields, if available, display automatically.

To display more of the Details fields on the screen, you can either:

  • Use the scroll bar.
  • Temporarily hide the list above the Details.
  • Click the  button above the list to display a pop-up version of the Details.

Step 3

Click the  button. The task is added to the database, and all buttons and tabs in the Task Details are enabled.

Note

To open an existing record on the list, either:

  • Click a record in the list to display its record Details below the list. (To clear record Details below the list, click the New button that displays above and below the Details.)
  • Clicking the Details icon next to a record name in the list, or right-click a record in the list and then click Open in the Action menu that displays, to display a pop-up version of the record Details.
  • Right-click a record in the a list, or open a record and right-click in the record Details, and then click Open In Tab in the Action menu that displays, to display the record Details under a new tab on the record list page (see Record Details as Tabs).

Linux/Unix Task Details

The following Linux/Unix Task Details is for an existing Linux/Unix task.

Depending on the values that you enter / select for these fields, and whether or not the Linux/Unix task has ever been launched, more (or less) fields may display. See the field descriptions, below, for a description of all fields that may display in the Linux/Unix Task Details.
 

Linux/Unix Task Details Field Descriptions

The following table describes the fields, buttons, and tabs that display in the Linux/Unix Task Details.
 

Field Name

Description

General

This section contains general information about the task.

Name

User-defined name of this task (Maximum = 255 alphanumeric characters); variables supported. It is the responsibility of the user to develop a workable naming scheme for tasks.

Version

System-supplied; version number of the current record, which is incremented by the Controller every time a user updates a record. Click the Versions tab to view previous versions. For details, see Record Versioning.

Description

Description of this record. Maximum length is 255 characters.

Member of Business Services

User-defined; Allows you to select one or more Business Services that this record belongs to.  (You also can Check All or Uncheck All Business Services for this record.)

You can select up to 62 Business Services for any record type, and enter a maximum of 2048 characters for each Business Service.

If the Business Service Visibility Restricted Universal Controller system property is set to true, depending on your assigned (or inherited) Permissions or Roles, Business Services available for selection may be restricted.

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

    Behavior determined by the parent workflow configuration.

  • 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.

Run as sudo

If Command or Script = Command; Run the command as sudo (superuser do).

The Run as sudo option prefixes the command with either:

  • sudo (if a credential is not specified; that is, the command is run as root)
  • sudo -u userid (if a credential is specified, where userid = the Runtime User from the supplied credential)

When using the Run as sudo option, you must grant Universal Broker userid authority to sudo to the requested userid without specifying its password; you can do this via the sudoers file. Please refer to your local security policy and documentation for updating the sudoers file.

Linux/Unix Details

This section contains assorted detailed information about the task.

Command or Script

Specifies whether a single command or a script is being executed.

Options:

  • Command (default)
  • Script

If the Windows/Linux Scripts Permitted Universal Controller system property is set to false:

  • The Command or Script field is set to Command and is read-only.
  • If the Command or Script field is set to Script, the field becomes modifiable so that you can change it to Command.

Script

Required if Command or Script = Script; Name of the script in the Controller database that will be executed by this task.
 

Note

If you click the Details icon for a Script selected in this field, the Script Type field in the Details is read-only.

Command

Required if Command or Script = Command; Command being executed on the remote machine. Variables supported.

Parameters


Any arguments needed by the program to execute properly. Variables supported.

Runtime Directory


Directory from which the application should be executed. Variables supported.

Environment Variables

Allows you to enter environment variables needed by the program to run.

To add a variable, click the + icon and enter a Name and Value. To delete a variable, select in the list of variables and click the - icon.

You can add a maximum of 4,000 characters for the combined Names and Values of all variables. The variable is listed in the space underneath.

Credential Functions, Database Connection Functions, SAP Connection Functions, Script Functions, Output Path Functions, and Variable Path Functions are supported. 

With Command or Script set to Script, the value of an environment variable named UAG_SCRIPT_DIRECTORY will be the directory where the temporary script file is written on the Agent system. The path formed with this value will be passed to the shell executing the script.

This variable and the variable UAG_SCRIPT_DIRECTORY_RELATIVE_TO is intended to support chroot environments, where the path used to refer to a script file may change depending on the context. The value of UAG_SCRIPT_DIRECTORY_RELATIVE_TO is prepended to UAG_SCRIPT_DIRECTORY when the Agent writes the script, but is not included in the path passed to the shell executing the script. For example, if a user's Agent system has a chroot in /jail, and wishes to see the script in /scripts while chrooted, they would set UAG_SCRIPT_DIRECTORY=/scripts and UAG_SCRIPT_DIRECTORY_RELATIVE_TO=/jail, so that UAG will write the script in /jail/scripts, and pass the path to the script to the shell as /scripts.

Result Processing DetailsThis section contains assorted detailed information about result processing for this task.

Specification for whether or not there is a restriction for this task to be run, skipped, or held.

Options are:

  • -- None -- No restriction for this task.
  • Run Restriction for when this task will be run.
  • Skip Restriction for when this task will be skipped.
  • Hold Restriction for when this task will be held.

If Execution Restriction on a task is Run or Skip, then when it is part of a Workflow that is being launched, the Restriction Period is evaluated. The task instance will be skipped if Execution Restriction is Skip and the date is within the Restriction Period or Execution Restriction is Run and the date is not within the Restriction Period. Execution Restriction can be set to Skip with a Restriction Period of - None -, meaning the restriction is always active and the task will be skipped when it is part of a Workflow.

Restriction Period

If Execution Restriction = Run, Skip, or Hold; Period of time when the task is restricted.

Options are:

  • – None –
    No period of restriction for this task.
  • Before
    Restriction is valid if the date is before the Before Date value.
  • After
    Restriction is valid if the date is after the After Date value.
  • Span
    Restriction is valid if the date is before the Before Date value and after After Date value.
  • On
    Restriction is valid if the date is one of the Date List values.

Before Date

If Restriction Period = Before or Span; Date before which the restriction is valid.

Before Time

If Restriction Period = Before or Span; Time on the selected date before which the restriction is valid.

After Date

If Restriction Period = After or Span; Date after which the restriction is valid.

After Time

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.

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.

Run as sudo

If Command or Script = Command; Run the command as sudo (superuser do).

The Run as sudo option prefixes the command with either:

  • sudo (if a credential is not specified; that is, the command is run as root)
  • sudo -u userid (if a credential is specified, where userid = the Runtime User from the supplied credential)

When using the Run as sudo option, you must grant Universal Broker userid authority to sudo to the requested userid without specifying its password; you can do this via the sudoers file. Please refer to your local security policy and documentation for updating the sudoers file.

Linux/Unix Details

This section contains assorted detailed information about the task instance.

Command or Script

Specifies whether a single command or a script is being executed.

Options:

  • Command (default)
  • Script

If the Windows/Linux Scripts Permitted Universal Controller system property is set to false:

  • The Command or Script field is set to Command and is read-only.
  • If the Command or Script field is set to Script, the field becomes modifiable so that you can change it to Command.

Script

Required if Command or Script = Script; Name of the script in the Controller database that will be executed by this task.
 

Note

If you click the Details icon for a Script selected in this field, the Script Type field in the Details is read-only.

Command

Required if Command or Script = Command; Command being executed on the remote machine. Variables supported.

Parameters


Any arguments needed by the program to execute properly. Variables supported.

Runtime Directory


Directory from which the application should be executed. Variables supported.

Environment Variables

Allows you to enter environment variables needed by the program to run.

To add a variable, click the + icon and enter a Name and Value. To delete a variable, select in the list of variables and click the - icon.

You can add a maximum of 4,000 characters for the combined Names and Values of all variables. The variable is listed in the space underneath.

Credential Functions, Database Connection Functions, SAP Connection Functions, Script Functions, Output Path Functions, and Variable Path Functions are supported. 

With Command or Script set to Script, the value of an environment variable named UAG_SCRIPT_DIRECTORY will be the directory where the temporary script file is written on the Agent system. The path formed with this value will be passed to the shell executing the script.

This variable and the variable UAG_SCRIPT_DIRECTORY_RELATIVE_TO is intended to support chroot environments, where the path used to refer to a script file may change depending on the context. The value of UAG_SCRIPT_DIRECTORY_RELATIVE_TO is prepended to UAG_SCRIPT_DIRECTORY when the Agent writes the script, but is not included in the path passed to the shell executing the script. For example, if a user's Agent system has a chroot in /jail, and wishes to see the script in /scripts while chrooted, they would set UAG_SCRIPT_DIRECTORY=/scripts and UAG_SCRIPT_DIRECTORY_RELATIVE_TO=/jail, so that UAG will write the script in /jail/scripts, and pass the path to the script to the shell as /scripts.

Result Processing DetailsThis section contains assorted detailed information about result processing for this task.

If the workflow starts at 9:00 a.m. but the task itself does not start until 10:30, the task has started late.

For a task that is not within a workflow, Late Start Duration has meaning only if the task has been held upon starting. For example, if a task has a Late Start Duration of 60 minutes and the Hold on Start field is enabled, if the task is not released from hold within the amount of time specified in the Late Start Duration field, the task has started late.

Computed Late Start Time

If Late Start is enabled, the computed Date/Time for when the task instance will be Late Started.

Late Finish

If enabled, and if the task instance finishes after the time or period specified, the task instance is flagged as late. You can specify a time or duration to determine a late finish (see Late Finish Type). To determine whether a task instance finished late, open the task instance and locate the Finished Late field; the field is checked if the instance finished after the specified time or lasted longer than expected. This field only appears on the task instance if the user specified a Late Finish in the task definition.

Finished Late

System-supplied; this field is flagged if the task finished later than the time or duration specified in the Late Finish fields.

Late Finish Type

Projected Late

System-provided if Late Start Time, Late Start Duration, or Late Finish Time is specified; This field is flagged if the task instance is projected to be late based on critical path projected end times (see Critical Path Projected Late Action Maximum and Critical Path Projected Late Threshold In Minutes Universal Controller system properties).

. 

Critical Path Options

This section contains Critical Path-related specifications for the task.

CP Duration

Optional; Allows you to override the estimated Critical Path Duration of the task when running in a Workflow; used in conjunction with the CP Duration Unit field. In most cases, this field should be left blank, which implies that the Controller will estimate the Critical Path Duration based on historical executions. Valid values are any integer equal to or greater than 0. Variables and Functions are supported.

CP Duration (Resolved)

Displays the current resolved value of the CP Duration field, which may contain variables or functions that will be displayed as unresolved until the task instance starts. The CP Duration (Resolved) field can continue to change value until the task instance starts, at which time CP Duration will display as resolved and CP Duration (Resolved) will no longer be visible unless there was an issue resolving the variables and/or functions contained within CP Duration. If the Controller is unable to resolve CP Duration or it resolves to an invalid value, CP Duration will be ignored and the Controller will estimate the Critical Path Duration based on historical executions.

CP Duration Unit

Type of CP Duration; used in conjunction with the CP Duration field. For example, for a CP Duration of two minutes, specify 2 in the CP Duration field and select Minutes in this field.
 

Options:

  • Seconds
  • Minutes
  • Hours

Default is Minutes.



Workflow Execution Options

This section contains Execution Restriction specifications for the task if it is within a Workflow.

Execution Restriction

Specification for whether or not there is a restriction for this task to be run, skipped, or held.

Options are:

  • -- None -- No restriction for this task.
  • Run Restriction for when this task will be run.
  • Skip Restriction for when this task will be skipped.
  • Hold Restriction for when this task will be held.

If Execution Restriction on a task is Run or Skip, then when it is part of a Workflow that is being launched, the Restriction Period is evaluated. The task instance will be skipped if Execution Restriction is Skip and the date is within the Restriction Period or Execution Restriction is Run and the date is not within the Restriction Period. Execution Restriction can be set to Skip with a Restriction Period of - None -, meaning the restriction is always active and the task will be skipped when it is part of a Workflow.

Restriction Period

If Execution Restriction = Run, Skip, or Hold; Period of time when the task is restricted.

Options are:

  • – None –
    No period of restriction for this task.
  • Before
    Restriction is valid if the date is before the Before Date value.
  • After
    Restriction is valid if the date is after the After Date value.
  • Span
    Restriction is valid if the date is before the Before Date value and after After Date value.
  • On
    Restriction is valid if the date is one of the Date List values.

Before Date

If Restriction Period = Before or Span; Date before which the restriction is valid.

Before Time

If Restriction Period = Before or Span; Time on the selected date before which the restriction is valid.

After Date

If Restriction Period = After or Span; Date after which the restriction is valid.

After Time

If Restriction Period = After or Span; Time on the selected date after which the restriction is valid.

Date List

If Restriction Period = On; Date(s) on which the restriction is valid.

Statistics

This section contains time-related statistics for the the task instance.
