High-Performance Loader overview
- Overview of HPL features
The High-Performance Loader (HPL) is a database server tool that you can use to load and unload large quantities of data efficiently to or from a database. - The HPL data-load process
The data-load process reads a source data file, converts the data to a different format, and inserts the converted data into a database table. - The HPL data-unload process
- HPL loading modes
The High-Performance Loader (HPL) offers two load modes, deluxe mode and express mode. The express mode is faster, and the deluxe mode is more flexible. - HPL components
The HPL consists of the onpload utility, the ipload utility, the onpladm command-line utility, and the onpload database. - Environment variables needed for the HPL
The High-Performance Loader (HPL) is part of the database server, so you must start the database server before you use the HPL. Before you start the database server and use HPL, you must set environment variables. - Architecture of the onpload utility
The ipload utility is the interface that allows you to prepare the parameters that the onpload utility uses. The onpload utility, which is a client application that attaches to the database server, actually loads and unloads the data.
