Effective in version 10.1, if the Data Integration Service runs on UNIX or Linux, you can create operating system profiles and configure the Data Integration Service to use operating system profiles. Use operating system profiles to increase security and to isolate the run-time user environment in Informatica products such as Big Data Management, Data Quality, and Intelligent Data Lake.
The Data Integration Service uses operating system profiles to run mappings, profiles, scorecards, and workflows. The operating system profile contains the operating system user name, service process variables, Hadoop impersonation properties, the Analyst Service properties, environment variables, and permissions. The Data Integration Service runs the mapping, profile, scorecard, or workflow with the system permissions of the operating system user and the properties defined in the operating system profile.
