Creating and Running a z/OS Task
Before You Begin
The z/OS task allow you to run a platform-specific application on a z/OS machine. To run a z/OS task, you must first complete the following tasks:
- Install Universal Agent for z/OS on a z/OS machine.
- Launch the Agent. When the Agent connects with the Universal Controller, it automatically creates an Agent resource definition in the database.
- Optionally, customize the Agent heartbeat and log levels, as described in z/OS Agent Details Field Descriptions.
Built-In Variables
The following built-in variables can be used in a z/OS task to pass data where appropriate:

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. |
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: 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. |
z/OS Details | This section contains assorted detailed information about the task instance. |
JCL Location |
File and member name containing the JCL script. When you are using the JCL_LIBRARY feature, you can substitute the name of the library with a string starting with "&", that names the library specified in the uags.conf file with the JCL_library definitions. For example, the name of a job might look like the following:
|
Use JCL Override Library | Allows the task to work with a JCL override library on the target system. If this option is selected, the Agent will check the JCL override path (specified in JCL Override Location) before submitting the job from JCL Location. |
JCL Override Location | If Use JCL Override Library is selected; Required. Specifies the file and member name potentially containing an override JCL script. |
Delete Override JCL | If Use JCL Override Library is selected; Optional. Allows the task to define criteria that will control the automated clean-up of the override JCL. If this option is not selected, the Controller and Agent will take no action to delete the override JCL from the target system. |
Submitted JCL Location | System-supplied; actual path that was used for job submission. |
Override Instance Count for Deletion | If Delete Override JCL is selected; Required. Specifies the number of successful override instances that must occur before the override JCL library member is deleted. Note Manual resubmissions of a task instance do not increment the tracked number of successful override instances that go towards satisfying the deletion criteria. |
Number of Override Instances | If Delete Override JCL is selected; Read only; system-supplied. Indicates the number of successful override instances that have occurred for this task. This number is checked against the deletion criteria to determine when the override JCL member should be deleted. Note This number is automatically reset to 0 by the system if a task instance does not submit from override JCL (that is, no override member was found). |
New Jobname |
Job name that will replace the one in the JCL member. This allows you to override the value in your JCL from the Controller without having to modify the JCL. This value should be validated before the job is launched to avoid JES start failures. The syntax of a job name is:
|
New Jobclass |
New Jobclass to replace the one in the JCL member. This allows you to override the value in your JCL from the Controller without having to modify the JCL. |
New Msgclass |
New MSGCLASS to replace the one in the JCL member. This allows you to override the value in your JCL from the Controller without having to modify the JCL. |
Procedure Library |
The PROCLIB field allows for defining a JES2 PROCLIB control statement in the job JCL. For example, a PROCLIB value of PROC01 will result in the following JES2 control statement generated in the job JCL:
The PROCLIB value must refer to a ddname defined in the JES2 procedure. Refer to IBM MVS JCL Reference for more information regarding the JES2 PROCLIB control statement. |
JCL Changes Confirmed | If Status = Confirmation Required; indicates that JCL changes have been confirmed. You cannot rerun a job if this field is not selected. |
Schedule ID |
|
SYSTEM or SYSAFF Override Parameter | Specifies the SYSTEM or SYSAFF Override Parameter using the following syntax: SYSTEM={SystemName} SYSAFF={MemberName} Value must conform to documented IBM JCL syntax. |
Parameters | Displays a list of parameters that will be inserted into the JCL. Each parameter consists of a Name and a Value. You can enter as many parameters as needed. To add a parameter, click the + icon; add a Name and Value, and click the Update button. To delete a parameter, click the parameter on the list, the - icon, and the Update button. Each parameter that you enter creates a separate JCL construct called the SET command. Each one appears as a new line inserted dynamically into the JCL submitted to the Controller for the current execution. The JCL is not permanently modified. For example, you might specify a parameter Name = RUNTYPE and Value = PROD. This results in the following JCL SET statement being inserted in the job after the job card: // SET RUNTYPE=PROD The Parameter fields also support two additional special functions:
|
Result Processing Details | This section contains assorted detailed information about result processing for this task. |
Exit Code Processing | Specifies how the Controller should determine whether the executed command failed or completed successfully. Options:
Note If Step Conditions has been selected for Exit Code Processing, and you then select a different option, a confirmation pop-up displays to warn that any defined Step Conditions will be removed. |
Output Type | Required if Exit Code Processing = Success Output Contains or Failure Output Contains; type of output. Options:
|
Scan Output For | Required if Exit Code Processing = Success Output Contains or Failure Output Contains; text for which the Controller should scan the output file. The Controller will process this field as a regular expression. |

Exit Codes | Required if Exit Code Processing = Success Exitcode Range or Failure Exitcode Range; range of exit codes. Format: Numeric. Use commas to list a series of exit codes; use hyphens to specify a range. Example: 1,5, 22-30. Variables are supported. |
Automatic Output Retrieval |
Specifies whether you want the Controller to automatically retrieve any output from the job and attach it to the task instance record. Options:
Note Tasks specifying Automatic Output Retrieval will fail with Start Failure if the Agent Output Prohibited field is true in the Details of the specified Agent. |
Wait For Output | If Automatic Output Retrieval = Standard Output, Standard Error, File, or Standard Output/Error, and Failure Only is not enabled (checked); Specification that the task should wait for the requested output before completing. |
Failure Only | If Automatic Output Retrieval = Standard Output, Standard Error, File, or Standard Output/Error, and Wait For Output is not enabled (checked); Indication for whether output should be retrieved on task failure only. |
Start Line | If Automatic Output Retrieval = Standard Output, Standard Error, File, or Standard Output/Error; Instructs the Controller to retrieve data beginning at the line indicated.
|
Number of Lines | If Automatic Output Retrieval = Standard Output, Standard Error, File, or Standard Output/Error; Allows you to limit the retrieved data to the number of lines specified. If a Number of Lines value is not specified, the default is the value of the Retrieve Output Default Number Of Lines Universal Controller system property. |
Scan Text | If Automatic Output Retrieval = Standard Output, Standard Error, File, or Standard Output/Error; Regex pattern that the Controller will search for a match for in STDOUT/STDERR or a specified file. The Controller will include the Number of Lines above and below the first line matched. |
Output File (for Automatic Output Retrieval) | Required if Automatic Output Retrieval = File; path and file name containing the output that you want automatically retrieved and attached to the task instance. |
Retry Options | This section contains specifications for retrying the task. |
Auto-Restart Option | Allows the z/OS job to be resubmitted with controlled step selection. This option is processed when/if a task transitions to a failed state. It works in conjunction with the Maximum Retries, Retry Interval, and Retry Indefinitely options. Note The Maximum Retries value must be greater than 0 for the Auto-Restart Option to be processed. Options:
If you select an option other that None for a task that ends in a failed state, audit records will be generated to record the step selection that took place for the restart. The audit records include all restart options, criteria matching, and directives that were used to select the set of job steps to be re-run. z/OS auto-restart audit records show up as audit type z/OS Auto-Restart from source Task Instance. Note If Use Restart Criteria has been selected for Auto-Restart Option, and you then select a different option, a confirmation pop-up displays to warn that any defined Restart Criteria will be removed. |
Maximum Retries |
User-defined; maximum number of times that the Controller should retry this task after it has started and gone to a failed state. |
Retry Indefinitely | User-defined; indicates whether the Controller should continue trying indefinitely to run this task. If you enable this field, it overrides any value placed in the Maximum Retries field. |

|
Delay Duration | If Delay On Start = Duration; Number of days, hours, minutes, and seconds to delay after starting the task. |
Delay Duration In Seconds | If Delay On Start = Seconds; Number of seconds to delay after starting the task. |
Time Options | This section contains time-related specifications for the task instance. |
Late Start | If enabled, and if the task instance starts after the time or period specified, the task instance is flagged as late. You can specify a time or duration to determine a late start (see Late Start Type). To determine whether a task instance started late, open the task instance and locate the Started Late field; the field is checked if the instance started after the specified time. The Started Late field displays in the task instance Details only if the user specified a Late Start in the task Details. |
Started Late | System-supplied; this field is flagged if the task started later than the time specified in the Late Start fields. |
Late Start Type | Required if Late Start is enabled. Options:
|
Late Start Time | If Late Start Type = Time; Time after which the task start time is considered late. Use HH:MM, 24-hour time. |

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. |

Computed Late Finish Time | If Late Finish is enabled, the computed Date/Time for when the task instance will be Late Finished. |
Early Finish | If enabled, and if the task instance finishes before the time or period specified, the task instance is flagged as early. You can specify a time or duration to determine an early finish (see Early Finish Type). To determine whether a task instance finished early, open the task instance and locate the Finished Early field; the field is checked if the instance finished before the specified time or did not last as long as expected. This field only appears on the task instance if the user added Early Finish specifications to the task definition. |
Finished Early | System-supplied; this field is flagged if the task finished earlier than the time specified in the Early Finish fields. |
Early Finish Type | Required if Early Finish is enabled. Options:
|

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 w |
