Offloading and Backing Up Datasets (TSIDOFL)

Description TSIDOFL offloads or backs up selected datasets according to the settings

on the UPSI statement and the contents of control statements.

Control statements specify which datasets and versions are to be

processed and are supplied as SYSIPT data. These control statements can

be generated by TSIDOFD or specified manually. Unless UPSI x1 is

present, TSIDOFL sorts the control statement information into

descending version within dataset name before beginning writing the

specified data to tape.

The offload tape is always associated with a cataloged dataset. You can

use the default offload dataset, OFFLOAD.DATA.SET, or you can create

your own dataset. If you create your own dataset, you must catalog the

dataset and supply a TLBL or DD statement using the DTF name

OUTPUT.

A tape version containing offloaded disk versions is not eligible for

scratch until all the offloaded disk versions either expire or are loaded

back to disk. In addition, any additional retention criteria attributed to the

tape version must be satisfied.
