Device arrays

A device array groups several I/O devices so that the High-Performance Loader (HPL) can perform parallel processing of the input and output. When you specify multiple devices in a device array, onpload sets up separate, parallel streams of input or output, when it performs a database load or unload.

Device arrays set up simultaneous access to one or more tape devices, files, or pipes (UNIX only) so that the onpload utility can take advantage of parallel processing.

Device arrays are not project specific. You can use the same device array for a load or unload job on any of the projects that you define.
