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

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 General tab of the Python Task Agent

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.

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.

The Add MIM dialog box

Here, you can insert the relevant MIM values.

Setting	Description
Assigned	Select the target assignee to which the MIM will be bound.
Name	Enter the name of the MIM value
Type	Select the data type, you can choose from the following supported data types: any, boolean, date, double, int, long, and string.

SQL Agent

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

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.
