Study Notes

Introduction to Parameter Sets

Parameter Sets in Informatica allow users to dynamically pass values to taskflow input parameters at runtime without external API calls.
Previously, this functionality required publishing taskflows as APIs and running them through external applications.

What is a Parameter Set?

A Parameter Set links a parameter file to a taskflow, defining values for taskflow input parameters.
This parameter file is uploaded to Informatica's cloud-hosted repository, ensuring its availability during taskflow execution.
During runtime, the taskflow retrieves values from the parameter file, ensuring dynamic parameterization.

ParamSetCli Utility

ParamSetCli is Informatica's command-line utility for managing Parameter Sets in the cloud-hosted repository.
It allows uploading, downloading, deleting and listing parameter sets, all from a local machine.

Setting up ParamSetCli

Java Runtime Environment Setup (Windows)

Verify if JRE is installed by running the java -version command in the command prompt.
If not installed, download and install the x64 Java installer from Oracle Java Downloads.
Add the path to the Java bin directory to the System Variables Path environment variable.
Create a new system variable named JAVA_HOME and set its value to the Java installation directory.
Verify successful installation by running java -version in a new command prompt.

Java Runtime Environment Setup (Linux)

Navigate to Oracle Java Downloads and copy the x64 RPM package download link.
Download the installation package to the desired directory using the wget command.
Install Java using the rpm -ivh command followed by the downloaded package path.
Test the installation with java -version.

Downloading ParamSetCli

Download the ParamSetCli utility from the Informatica Community article linked in the text.
Unzip the downloaded zip file to a desired location.

The downloaded restenv.properties file contains preloaded login credentials for connecting to Informatica Intelligent Cloud Services.
Configure the following parameters in restenv.properties:
- rest.endpoint: The endpoint URL for the Informatica Intelligent Cloud Services.
- rest.login: Username for Informatica Intelligent Cloud Services.
- rest.password: Password for Informatica Intelligent Cloud Services.

Password Encryption

To use an encrypted password in restenv.properties, set the use.encryption flag to true and use the following command:
- paramsetcli.bat/sh runParamSetCli createEncryptedPassword -password <password>

Parameter File Setup

The parameter file used in a Parameter Set is similar to those used in mapping tasks.
Multiple parameter definitions within a parameter set take precedence based on scope, with the smallest scope overriding larger ones.
Parameter names are preceded by two dollar signs ($$), followed by their values separated by an equal sign (=).

ParamSetCli Utility Commands

Use paramsetcli.bat (Windows) or paramsetcli.sh (Linux) from the downloaded zip file.

Uploading a Parameter Set

Use the following syntax:
- paramsetcli.bat/sh runParamSetCli upload -name <ParameterSetName> -file <paramfile.properties>
File size limit: 5 MB

Downloading a Parameter Set

Use the following syntax:
paramsetcli.bat/sh runParamSetCli download -name <ParameterSetName> -file <paramfile.properties>

Deleting a Parameter Set

Use the following syntax:
paramsetcli.bat/sh runParamSetCli delete -name <ParameterSetName>

Listing Parameter Sets

Use the following syntax:
- paramsetcli.bat/sh runParamSetCli list

Running IICS Taskflow with a Parameter Set

Create and upload the parameter file using the ParamSetCli upload command.
In the taskflow, navigate to the Start step.
In the Start step's Start tab, specify the parameter set name in the "Parameter Set" field.
Define input fields in the Start step, matching the parameter names in the parameter set.
Use these input fields throughout the taskflow.
Save and publish the taskflow.

Conclusion

Parameter Sets enable deploying taskflows with varying input parameter values across environments without modifying the taskflow itself.
Key considerations while using Parameter Sets:
- Ensure the parameter file is uploaded to the cloud-hosted repository.
- Use the correct Parameter Set name in the taskflow's Start step.
- Match input fields in the taskflow with parameter names in the parameter file.
