Device arrays

A device array groups several I/O devices so that the 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.
