You can also improve the performance of a dump operation by creating a non-restartable dump. However, if a non-restartable dump operation fails, you will not be able to restart the dump from the failure point. Instead, you must create a new dump record object to start the dump operation from the beginning.
A dump operation can only be non-restartable if it is a partial repository dump. Full repository dump operations are always restartable.
To create a non-restartable dump, set the dump_parameter property to restartable=F.
