If you extract data from or load data into Siebel EIM tables and a fatal error occurs, the PowerCenter Integration Service terminates the session.
The PowerCenter Integration Service terminates the session when you invoke an EIM task and any of the following fatal errors occur:
Connection errors
Invalid IFB file
Failure to invoke an EIM task
If a session timeout occurs, the Siebel server continues to run the EIM task even though the PowerCenter Integration Service terminates the session. However, the PowerCenter Integration Service does not write the EIM task ID to the session log.
