Default: system-generated name of the form SYS_EXPORT_<mode>_NN
Purpose
Used to identify the export job in subsequent actions, such as when the ATTACH parameter is used to attach to a job, or to identify the job using the DBA_DATAPUMP_JOBS or USER_DATAPUMP_JOBS views.
Syntax and Description
JOB_NAME=jobname_string
The jobname_string specifies a name of up to 30 bytes for this export job. The bytes must represent printable characters and spaces. If spaces are included, then the name must be enclosed in single quotation marks (for example, 'Thursday Export'). The job name is implicitly qualified by the schema of the user performing the export operation. The job name is used as the name of the master table, which controls the export job.
The default job name is system-generated in the form SYS_EXPORT_<mode>_NN, where NN expands to a 2-digit incrementing integer starting at 01. An example of a default name is 'SYS_EXPORT_TABLESPACE_02'.
Example
The following example shows an export operation that is assigned a job name of exp_job:
> expdp hr DIRECTORY=dpump_dir1 DUMPFILE=exp_job.dmp JOB_NAME=exp_job NOLOGFILE=YES
