In case of failure or any other circumstances that prevent the Data Pump job from successfully ending its work, an implicit recommencing feature is activated. The job enters a suspended mode that allows the DBA to attach this feature to the job. It is important to emphasize that the master job table must positively identify the interrupted job, otherwise it won't be possible to restart the job once the circumstance behind the failure has been properly corrected.

In order for the user to attach to the job, it must be connected with the ATTACH command line option properly set. At this point, it becomes evident why it is a good practice to have a name for the data pump job, other than the default system generated name.
