How do you pass variables between sessions in Informatica?
1 Answer
- In mapping1 create a mapping variable say var1 and set its value to join_date.
- Create a workflow variable in the workflow, say var_wkf.
- In session1, in Post-session on success variable assignment, assign var_wkf = var1.
- In mapping2, create a mapping variable, say var2.
What is $$ $$$ in Informatica?
$$$ refers System Parameters like $$$SessStartTime. Actually $ means internal Parameter/Variable (such as $DBConnection prefix or $PMSessionLogDir) whereas $$ are used for user-defined parameters or variables (which could be defined at mapping or workflow/worklet level).
What is session level parameters in Informatica?
Session parameters are either user-defined or built-in. Use user-defined session parameters in session or workflow properties and define the values in a parameter file. When you run a session, the Integration Service matches parameters in the parameter file with the parameters in the session.
What is set variable in Informatica?
Sets the current value of a mapping variable to a value you specify. Based on the aggregate type of the variable, it saves a final current value to the repository. Unless overridden, it uses the saved value as the initial value of the variable for the next session run.
How do you pass a mapping variable to workflow variable in Informatica?
If the value is ‘X’ run session S1, if ‘Y’ run session S2. I tried creating a Mapping variable and assigning it with the value I calculated using SETVARIABLE and finally assigned it to the workflow variable using post session variable assignment. That workflow variable,then I used it in the LINKs between sessions.
What are session parameters?
A session parameter is a variable that IBM® Cognos® Framework Manager associates with a session. For example, user ID and preferred language are both session parameters. Because session parameters are key and value pairs, you can think of each session parameter as an entry in a parameter map named Session Parameters.

How to get infomatica session start time, Sessi?
Session start time, end time, status, and numbers of processed / produced rows are available as workflow variables, e.g. $s_m_LoadSession1.SrcSuccessRows (please don’t nail me down on the syntax, you can look up these variables in one of the workflow guides or maybe in the Transformation Language guide for PowerCenter, not sure).
What does setvariable do in Informatica powercenter-ETL?
SETVARIABLE sets the variable to a value that you specify (executes only if a row is marked as insert or update). At the end of a successful session, the Integration Service saves either the MAX or MIN of (start value.final value) to the repository, depending on the aggregate type of the variable.
What happens to the variable at the end of a session?
At the end of a successful session, the Integration Service saves either the MAX or MIN of (start value.final value) to the repository, depending on the aggregate type of the variable. Unless overridden, it uses the saved value as the start value of the variable for the next session run.
Where do I set the parameters in Informatica?
Parameters can be set on workflow, worklet or session level. The physical location of a parameter file is set in Workflow manager in Workflows -> Edit. It can also be specified using the pmcmd command when starting a session task.
