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.

The onpload utility can take advantage of parallel processing to perform both I/O and data conversion as efficiently as possible because it uses the same multithreading architecture that the database server uses.

The following sections describe how onpload uses multithreading for deluxe loads, express loads, and unloads.
