After you create a session, you can edit it. For example, you might need to adjust the buffer and cache sizes, modify the update strategy, or clear a variable value saved in the repository.
Double-click the Session task to open the session properties. The session has the following tabs, and each of those tabs has multiple settings:
Enter session name, mapping name, and description for the Session task, assign resources, and configure additional task options.
Enter session log information, test load settings, and performance configuration.
Config Object tab.
Enter advanced settings, log options, and error handling configuration.
Enter source and target information, override transformation properties, and configure the session for partitioning.
Configure pre- or post-session shell commands and emails.
Metadata Extension tab.
Configure metadata extension options.
You can edit session properties at any time. The repository updates the session properties immediately.
If the session is running when you edit the session, the repository updates the session when the session completes. If the mapping changes, the Workflow Manager might issue a warning that the session is invalid. The Workflow Manager then lets you continue editing the session properties. After you edit the session properties, the Integration Service validates the session and reschedules the session.
