The Unload Job windows
You can create an unload job or select an existing job for editing from the Unload Job Select window.
From the Unload Job window, you can also create or modify the components of an unload job and run the unload job. You can change unload options before you run the unload job. The unload options include the isolation level and the maximum number of errors to permit before onpload stops the unload job.
The ipload utility stores the information about the unload job in the session table of the onpload database. The session table draws information from other onpload tables, such as maps, formats, and so on.
