0 - 2 of 2 tags for blocking

Hi guys,
just want to ask the purpose of Serialize ON in TPUMP. How is it related to the types of blocking or locking if it is not specified in a TPUMP? Are there any circumstances that would affect the blocking or locking?
Thanks! :)

The Teradata Named Pipe Access Module (NPAM) provides an inter-process communication link between a writer process (such as FastExport) and a reader process (such as FastLoad).  The NPAM can also be used by Teradata Parallel Transporter (TPT) for data transfer.

This article details the different modes in which Named pipes are opened and used by NPAM for data transfer activity.
