Relationships among the parts of the HPL

The following figure shows the relationships among the parts of the High-Performance Loader (HPL). The ipload utility or onpladm command-line utility connects to the database server to populate the onpload database. The ipload utility or the onpladm utility controls the onpload utility, which uses multithreaded architecture to make multiple connections to the database server and multiple I/O connections to tapes, files, or pipes.
