Oracle 18c Datapump-PARALLEL Parameter

PARALLEL :-

• PARALLEL parameter is used to improve the speed of the export and import.
• The PARALLEL parameter specifies the maximum number of threads of active execution operating on behalf of the export job.Each Data Pump execution thread writes exclusively to one file at a time.
• This PARALLEL option can be used in conjunction with the “%U” wildcard in the DUMPFILE parameter to allow multiple dumpfiles to be created or read. The same wildcard can be used during the import to allow you to reference multiple files.
• The PARALLEL parameter is valid only in the Enterprise Edition of the Oracle database.
