Workflow in Informatica: Create, Task, Parameter, Reusable, Manager
![assignment task in informatica bdm David Carter](https://www.guru99.com/images/david-carter-author-120x120.png)
What is Workflow?
Workflow is a group of instructions/commands to the integrations service in Informatica. The integration service is an entity which reads workflow information from the repository, fetches data from sources and after performing transformation loads it into the target.
Workflow – It defines how to run tasks like session task, command task, email task , etc.
To create a workflow
- You first need to create tasks
- And then add those tasks to the workflow.
A Workflow is like an empty container, which has the capacity to store an object you want to execute. You add tasks to the workflow that you want to execute. In this tutorial, we are going to do following things in workflow.
![assignment task in informatica bdm Workflow in Informatica](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn1.png)
Workflow execution can be done in two ways
- Sequence : Tasks execute in the order in which they are defined
- Event based : Tasks gets executed based on the event conditions.
How to open Workflow Manager
Step 1) In the Informatica Designer, Click on the Workflow manager icon
![assignment task in informatica bdm Open Workflow Manager](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn2.png)
Step 2) This will open a window of Workflow Manager. Then, in the workflow Manager.
- We are going to connect to repository “guru99”, so double click on the folder to connect.
- Enter user name and password then select “Connect Button”.
![assignment task in informatica bdm Open Workflow Manager](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn3.png)
Step 3) In the workflow manager.
- Right click on the folder
- In the pop up menu, select open option
![assignment task in informatica bdm Open Workflow Manager](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn4.png)
This will open up the workspace of Workflow manager.
![assignment task in informatica bdm Open Workflow Manager](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn5.png)
How to Create Connections for Workflow Manager
To execute any task in workflow manager, you need to create connections . By using these connections, Integration Service connects to different objects.
For Example, in your mapping if you have source table in oracle database, then you will need oracle connection so that integration service can connect to the oracle database to fetch the source data.
Following type of connections can be created in workflow manager.
- Relational Connection
- Ftp Connection
- Application
The choice of connection you will create, will depend on the type of source and target systems you want to connect. More often, you would be using relational connections.
To Create a Relational Connection
Step 1) In Workflow Manager
- Click on the Connection menu
- Select Relational Option
![assignment task in informatica bdm Create a Relational Connection](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn6.png)
Step 2) In the pop up window
- Select Oracle in type
- Click on the new button
![assignment task in informatica bdm Create a Relational Connection](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn7.png)
Step 3) In the new window of connection object definition
- Enter Connection Name (New Name-guru99)
- Enter username
- Enter password
- Enter connection string
- Leave other settings as default and Select OK button
![assignment task in informatica bdm Create a Relational Connection](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn8.png)
Step 4) You will return on the previous window. Click on the close button.
![assignment task in informatica bdm Create a Relational Connection](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn9.png)
Now you are set with the relational connection in workflow manager.
Components of Workflow manager
There are three component tools of workflow manager that helps in creating various objects in workflow manager. These tools are
- Task Developer
- Worklet Designer
- Workflow Designer
![assignment task in informatica bdm Components of Workflow manager](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn10.png)
Task Developer – Task developer is a tool with the help of which you can create reusable objects. Reusable object in workflow manager are objects which can be reused in multiple workflows. For Example, if you have created a command task in task developer, then you can reuse this task in any number of workflows.
The role of Workflow designer is to execute the tasks those are added in it. You can add any no of tasks in a workflow.
You can create three types of reusable tasks in task developer.
- Command task
- Session task
Command task – A command task is used to execute different windows/unix commands during the execution of the workflow. You can create command task to execute various command based tasks. With help of this task you can execute commands to create files/folders, to delete files/folders, to do ftp of files etc.
Session Task – A session task in Informatica is required to run a mapping.
- Without a session task, you cannot execute or run a mapping
- A session task can execute only a single mapping. So, there is a one to one relationship between a mapping and a session
- A session task is an object with the help of which informatica gets to know how and where to execute a mapping and at which time
- Sessions cannot be executed independently, a session must be added to a workflow
- In session object cache properties can be configured and also advanced performance optimization configuration.
Email task – With the help of email task you can send email to defined recipients when the Integration Service runs a workflow. For example, if you want to monitor how long a session takes to complete, you can configure the session to send an email containing the details of session start and end time. Or, if you want the Integration Service to notify you when a workflow completes/fails, you can configure the email task for the same.
How to create command task
Step 1) To create a command task we are going to use Task Developer. In Workflow Manager, open the task developer by clicking on tab “task developer” from the menu.
![assignment task in informatica bdm Create Command Task](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn11.png)

- Enter workflow name
- Select OK Button ( leave other options as default)
![assignment task in informatica bdm Create Workflow to Execute Command Task](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn22.png)
This will create the workflow.
Naming Convention – Workflow names are prefixed with using ‘ wkf_’ , if you have a session named ‘ s_m_employee_detail ‘ then workflow for the same can be named as ‘ wkf_s_m_employee_detail’ .
![assignment task in informatica bdm Create Workflow to Execute Command Task](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn23.png)
When you create a workflow, it does not consist of any tasks. So, to execute any task in a workflow you have to add task in it.
Step 4) To add command task that we have created in Task developer to the workflow desinger
- In the navigator tree, expand the tasks folder
- Drag and drop the command task to workflow designer
![assignment task in informatica bdm Create Workflow to Execute Command Task](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn24.png)
Step 5) Select the “link task option” from the toolbox from the top menu. (The link task option links various tasks in a workflow to the start task, so that the order of execution of tasks can be defined).
![assignment task in informatica bdm Create Workflow to Execute Command Task](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn25.png)
Step 6) Once you select the link task icon, it will allow you to drag the link between start task and command task. Now select the start task and drag a link to the command task.
![assignment task in informatica bdm Create Workflow to Execute Command Task](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn26.png)
Now you are ready with the workflow having a command task to be executed.

![assignment task in informatica bdm Execute Workflow](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn28.png)
Once the workflow is executed, it will execute the command task to create a folder (guru99 folder) in the defined directory.
![assignment task in informatica bdm Execute Workflow](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn29.png)
Session Task
A session task in Informatica is required to run a mapping.
Without a session task, you cannot execute or run a mapping and a session task can execute only a single mapping. So, there is a one to one relationship between a mapping and a session. A session task is an object with the help of which Informatica gets to know how and where to execute a mapping and at which time. Sessions cannot be executed independently, a session must be added to a workflow. In session object cache properties can be configured and also advanced performance optimization configuration.

How to add tasks in serial mode
But before we add tasks in serial mode, we have to delete the task that we added to demonstrate parallel execution of task. For that
Step 1) Open the workflow “w.kf_run_command”
- Select the link to the session task.
- Select edit option in the menu
- Select delete option
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn52.png)
Step 2) Confirmation dialogue box will appear in a window, select yes option
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn53.png)
The link between the start task and session task will be removed.
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn54.png)
Step 3) Now again go to top menu and select the link task option from the toolbox
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn55.png)
Step 4) link the session task to the command task
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn56.png)
After linking the workflow will look like this
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn57.png)
Step 5) To make the visual appearance of workflow more clear
- Right click on wokspace of workflow
- Select arrange menu
- Select Horizontal option
![assignment task in informatica bdm Add Tasks in Serial Mode](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn58.png)
If you start the workflow the command task will execute first and after its execution, session task will start.
Workflow Variable
Workflow variables allows different tasks in a workflow to exchange information with each other and also allows tasks to access certain properties of other tasks in a workflow. For example, to get the current date you can use the inbuilt variable “sysdate”.
Most common scenario is when you have multiple tasks in a workflow and in one task you access the variable of another task. For example, if you have two tasks in a workflow and the requirement is to execute the second task only when first task is executed successfully. You can implement such scenario using predefined variable in the workflow.
Implementing the scenario
We had a workflow “wkf_run_command” having tasks added in serial mode. Now we will add a condition to the link between session task and command task, so that, only after the success of command task the session task will be executed.
Step 1) Open the workflow “wkf_run_command”
![assignment task in informatica bdm Implementing the Scenario](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn60.png)
Step 2) Double click on the link between session and command task
![assignment task in informatica bdm Implementing the Scenario](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn61.png)
An Expression window will appear
![assignment task in informatica bdm Implementing the Scenario](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn62.png)
Step 3) Double click the status variable under “cmd_create_folder” menu. A variable “$cmd_create_folder.status” will appear in the editor window on right side.
![assignment task in informatica bdm Implementing the Scenario](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn63.png)
Step 4) Now we will set the variable “$cmd_create_folder.status” condition to succeeded status . which means when the previous tasks is executed and the execution was success, then only execute the next session task.
- Change the variable to “$cmd_create_folder.status=SUCCEEDED” value.
- Click OK Button
![assignment task in informatica bdm Implementing the Scenario](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn64.png)
The workflow will look like this
![assignment task in informatica bdm Implementing the Scenario](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn65.png)
When you execute this workflow, the command task executes first and only when it succeeds then only the session task will get executed.
Workflow Parameter
Workflow parameters are those values which remain constant throughout the run. once their value is assigned it remains same. Parameters can be used in workflow properties and their values can be defined in parameter files. For example, instead of using hard coded connection value you can use a parameter/variable in the connection name and value can be defined in the parameter file.
Parameter files are the files in which we define the values of mapping/workflow variables or parameters. There files have the extension of “.par”. As a general standard a parameter file is created for a workflow.
Advantages of Parameter file
- Helps in migration of code from one environment to other
- Alows easy debugging and testing
- Values can be modified with ease without change in code
Structure of parameter file
The structure of parameter file
- [folder_name.WF:Workflow_name]
- $Parameter_name=Parameter_value
Folder_name is the name of repository folder, workflow name is the name of workflow for which you are creating the parameter file.
We will be creating a parameter file for the database connection “guru99” which we assigned in our early sessions for sources and targets.
How to create parameter file
Step 1) Create a new empty file (notepad file)
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn66.png)
Step 2) In the file enter text as shown in figure
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn67.png)
Step 3) Save the file under a folder guru99 at the location “C:\guru99” as “wkf_run_command.par”
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn68.png)
In the file we have created a parameter “$DBConnection_SRC”, we will assign the same to a connection in our workflow.
Step 4) Open the workflow “wkf_run_command”
- Select edit option
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn69.png)
Step 5) This will open up edit workflow window, in this window
- Go to properties tab menu
- Enter the parameter file name as “c:\guru99\wkf_run_command.par”
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn70.png)
Now we are done with defining the parameter file content and point it to a workflow.
Next step is to use the parameter in session.
Step 6) In workflow double click on the session “s_m_emp_emp_target”, then
- Select mappings tab menu
- Select connection property in the left panel
- Click on the target connection, which is hardcoded now as “guru99”
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn71.png)
Step 7) A connection browser window will appear, in that window
- Select the option to use connection variable
- Enter connection variable name as “$DBConnection_SRC”
- Select Ok Button
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn72.png)
Step 8) In the edit task window connection variable will appear for the target, Select OK button in the edit task window.
![assignment task in informatica bdm Create Parameter File](https://www.guru99.com/images/informatica/083115_0719_WorkflowsIn73.png)
Now we are done with creating parameter for a connection and assigning its value to parameter file.
When we execute the workflow, the workflow picks the parameter file looks for the value of its paramters/variables in the parameter file and takes those values.

Hi Admin, May I know how are you increasing value by one for $$Session_Counter after each successful run?
Hi Vaibhav, Please see about post 9th point. 9. Enter the value or expression you want to assign. If you have still doubt, please let me know.
Hi..nice solution...but i have multiple sessions in my workflow..is there any other technique than using assignment task at session level
Hi goutham, I don't how to assign the values of workflow variables to target.
How can we solve that when the source file getting along with date and time ,but we do not require that date and time with document name as target
can we assign the the value of variable in the parameter file?
Si así lo requieres si se puede asignar desde un archivo de parámetros pero depende de la necesidad.

You can add an Assignment task to the workflow to assign another value to the variable. The Data Integration Service uses the assigned value for the variable during the remainder of the workflow. For example, you create a counter variable and set the initial value to 0. In the Assignment task, you increment the variable by setting the variable ...
Click Create. Then click Done. The Workflow Designer creates and adds the Assignment task to the workflow. Double-click the Assignment task to open the Edit Task dialog box. On the Expressions tab, click Add to add an assignment. Click the Open button in the User Defined Variables field. Select the variable for which you want to assign a value.
An Assignment task assigns a value to a user-defined workflow variable. Add an Assignment task before the Mapping task in the workflow. Use an expression in the Assignment task to assign the value of the department name parameter and the current date to the workflow variable. Right-click the workflow editor and select. Add Workflow Object.
As a workflow progresses, the Data Integration Service can calculate and change the initial variable value according to how you configure the workflow. You can assign a value to a user-defined variable using an Assignment task. Or, you can assign a value to a user-defined variable using task output.
In the workflow, create a non-reusable task (s_m_dummy) pointing to the mapping. In the session, click components > post session on success variable assignment > Assign mapping variable to workflow variable for both parameters. In the same workflow create a command task and link it from session s_m_dummy. In the command task edit the command as ...
For example, each task includes an Is Successful output value that indicates whether the task ran successfully. The workflow cannot directly access this task output data. To use the data in the remainder of the workflow, you create a boolean workflow variable named TaskSuccessful and assign the Is Successful output to the variable.
Before you can define a variable in the assignment task, you need to add the variable in Workflow Manager. To add a variable to the Workflow, perform the following steps: In Workflow Manager, open the workflow for which you wish to define user-defined variables. Navigate to Workflow | Edit | Variables. Click on the Add a new variable option to ...

Introduction. Informatica ® Big Data Management ™ allows users to build big data pipelines that can be seamlessly ported on to any big data ecosystem such as Amazon AWS, Azure HDInsight and so on. A pipeline built in the Big Data Management (BDM) is known as a mapping and typically defines a data flow from one or more sources to one or more targets with optional transformations in between.
Step 1) In the Informatica Designer, Click on the Workflow manager icon. Step 2) This will open a window of Workflow Manager. Then, in the workflow Manager. We are going to connect to repository "guru99", so double click on the folder to connect. Enter user name and password then select "Connect Button".
Create the Principal Name and Keytab Files in the Active Directory Server. Step 5. Specify the Kerberos Authentication Properties for the Data Integration Service. Step 6. Configure the Execution Options for the Data Integration Service. Configuring Big Data Management to Access an SSL-Enabled Cluster.
Tasks Overview. The Workflow Manager contains many types of tasks to help you build workflows and worklets. You can create reusable tasks in the Task Developer. Or, create and add tasks in the Workflow or Worklet Designer as you develop the workflow. The following table summarizes workflow tasks available in Workflow Manager: Task Name. Tool.
Use a Command Task step to run shell scripts or batch commands from multiple script files on the Secure Agent machine. For example, you can use a command task to move a file, copy a file, zip or unzip a file, or run clean scripts or SQL scripts as part of a taskflow. You can use the Command Task outputs to orchestrate subsequent tasks in the ...
We will use Decision Transformation to achieve this. We define a strategy and concatenate the results of the previous if statement to the current one and obtain the entire result. The mapping looks like the following: The strategy definition is: The output port product is reused in the next if statement. That is, the result of next if statement ...
To create an Informatica Command Task, First, go to the Task Developer Tab. Next, navigate to Tasks Menu and select the Create option. Once you select the Create option, a new window called Create Task will open. First, select the Command Task, provide a unique name for this Task and click on the Create button.
The Integration Service evaluates the condition in the Decision task and sets the predefined condition variable to True (1) or False (0). We can specify one decision condition per Decision task. Depending on the workflow, we might use link conditions instead of a Decision task.
Step 4. Create the Principal Name and Keytab Files in the Active Directory Server. Step 5. Specify the Kerberos Authentication Properties for the Data Integration Service. Step 6. Configure the Execution Options for the Data Integration Service. Configuring Big Data Management to Access an SSL-Enabled Cluster.
