UPSI Values The following UPSI values can be used when offloading and backing up

datasets.

WARNING:

If UPSI x1 is used with a TSIFOFL execution where the TSIDOFL

control statements were NOT created by the TSIDOFD program,

it becomes the your responsibility to verify that, when multiple

versions of a dataset are restored using TSIDONL, the oldest

version is restored first, the second oldest version is restored

second, and so on.

Dataset

Requirements

OUTPUT specifies a tape dataset that will be the offload/backup tape.

Note:Note:

This dataset name must be cataloged. If a label is not supplied for the

OUTPUT dataset, TSIDOFL catalogs the dataset using the dataset name

OFFLOAD.DATA.SET.

IJSYSIN specifies that the input control statements reside on a

TSIDOFD-created tape or disk dataset instead of on SYSIPT. You can

use either standard VSE assignments or GDI.

PARM Values PARM=’DLAUPD=NO’ can be specified on the EXEC Job Control

statement. This prevents the offload/backup job name and current date

Position Setting Function

0 0 Specifies OFFLOAD function

1 Specifies BACKUP function.

Note: If control statements for Start Track 1

datasets are submitted, UPSI 1 is automatically

forced since OFFLOAD cannot be done for Start

Track 1 datasets.

1 1 Specifies the control statements are not sorted and

datasets are offloaded in the order in which the

control statements were submitted.

2 1 Specifies that the DSN selection will be by

generation number rather than by version number.

Do not use if TSIDOFD created the control

statements.
