Task workflows are used to execute system housekeeping tasks such as removing files or cleaning up database tables. The following are the Task Workflow agents we have:

Data Hub Task Agent

The Data Hub Task agent is explained in detail in Data Hub Task Agent.

Data Veracity Task Agent

The Data Veracity Task Agent is explained in detail in Data Veracity Task Agent.

Python Task Agent

The Python Task Agent runs Python scripts and is configured in two tabs – General where the code is entered and MIM where MIM values can be freely assigned. 

General

The Python collection agent configuration - General tab

In the General tab, you enter the selected code string that needs to be executed in a task workflow. You can Validate the input code and confirm your choice by clicking on the OK button.

Code Area

This is the text area where you enter your code, see Python Writer's Guide for further information.

The entered code will be color-coded depending on the code type, and for input assistance, a pop-up menu is available.

Below the text area, there are line, column, and position indicators. See Python Code Editor Assistance.

Interpreter

Select which https://infozone.atlassian.net/wiki/x/SBU0D you want to use. If no selection is made the interpreter that has been set as default in the https://infozone.atlassian.net/wiki/x/uwgzD will be used.

MIM

The MIM tab of the Python Task Agent

 

You can assign MIM values and edit entries using the Add, Edit, Remove, Up, and Down buttons. 

When you click on the Add button the Add MIM dialog box will open. 

 

Here, you can insert the relevant MIM values.

SQL Agent

The SQL agent executes an SQL statement or script in the database specified by a database profile.

Database

Click Browse... to select a Database profile.

For further information about how to configure a Database profile, see Database Profile.

SQL Statement

Enter a PL/SQL script or SQL statements.

Note!

Group several SQL statements within a block. For a single SQL statement omit the semicolon (;) at the end.

Script Agent

This agent runs a shell script or other executable located on the filesystem of an EC. The workflow will stop when it receives an exit code from the script. If the script returns a non-zero exit code, the workflow will abort. Output to stdout will appear in the debug output from the agent.

Warning!

It is strongly recommended that you run script task workflows on a separate EC. Running script task workflows on the same EC as other workflows may cause unpredictable errors and loss of data.

During a short time before exec() runs the actual script, fork() allocates the same amount of memory for the script as used for the EC. If the memory is not available, the EC will abort with an out-of-memory error and must then be restarted.

Description

Script Name

Enter the absolute path and name of the script file or executable that will perform the task.

You may omit the path if it is not required by the shell. For instance, to remove files or directories you can simply enter rm or rmdir.

Parameters

Enter the arguments and options expected by the script. The value will be passed as-is to the shell, except for carriage return characters, which will be handled as a blank spaces.

To call the script without options parameters, leave this field blank.

Unit Test Runner Agent

This task agent executes unit tests. You can customize the queries and define the exact location where the reports are saved.
