A session is a set of instructions that tells the Integration Service how and when to move data from sources to targets. A session is a type of task, similar to other tasks available in the Workflow Manager. In the Workflow Manager, you configure a session by creating a Session task. You can run as many sessions in a workflow as you need. You can run the Session tasks sequentially or concurrently, depending on the requirement.


When you create a Session task, you enter general information such as the session name, session schedule, and the Integration Service to run the session. You can also select options to run pre-session shell commands, send On-Success or On-Failure email, and use FTP to transfer source and target files.
