TSIDONL Control Statements Offload System

13-30 User Reference

Each backed up or offloaded dataset is processed as a separate entity. Therefore, if for any

reason a multi-dataset onload or restore job terminates abnormally and is restarted, special

restart considerations are necessary. In order to avoid dataset duplication and maintain

version order integrity, the job must be restarted on the dataset being processed at the time the

abend occurred. Use the following procedure.

Step Action

1 Refer to the restore/onload report and obtain the last dataset name and generation

listed.

2 Compare this to the backup/offload report and obtain the next dataset name (and

generation number, if appropriate).

3 Restart TSIDONL using a START control statement specifying the dataset name

and generation from Step 2.

START='

dataset-name

generation-number

dataset-name specifies the name of the dataset with which to begin onload or restore

processing.

generation-number specifies the absolute generation number of the disk dataset. The

generation number can be omitted for a work dataset identified in the BIM-EPIC catalog and

MUST be omitted for a start-track-1 dataset.

The following job onloads all the datasets on the tape. It uses version 1 of the default offload

dataset. The datasets remain assigned to their current relative version number (based upon

absolute generation number) unless that version has been scratched. If the version has been

scratched, they are assigned to version number 1.

// JOB ONLOAD

// EXEC TSIDONL

The following job restores all generations of the ACCOUNTS.PAY dataset. Each generation

is assigned version number 1 as it is restored. The last version restored is version number 1.

Because datasets are copied in reverse version order, the last version restored is the newest

version on the tape.

// JOB RESTORE

// UPSI 110

// EXEC TSIDONL

'ACCOUNTS.PAY',*

The following job onloads all datasets starting with and written after generation 112 of the

ACCOUNTS.PAY dataset. The datasets remain assigned to their current relative version

number unless that version has been scratched. If the version has been scratched, they are

assigned to version number 1. The job uses version 1 of the USER.DATA.SET offload tape.
