Offload System Offloading and Backing Up Datasets (TSIDOFL)

Chapter 13. Disk Space Management 13-23

// RESET SYSIPT

UPSI 0 specifies OFFLOAD.

UPSI 1 specifies BACKUP. Note that if control statements for start-track-1 datasets are

submitted, UPSI 1 is automatically forced.

UPSI x1 specifies special handling when the number of control statements exceeds the internal

work area used by TSIDOFL. When this UPSI setting is used, the control statements are not

sorted, and datasets are offloaded in the order in which the control statements are submitted.

UPSI xx1 specifies that DSN selection will be by Generation Number rather than by Version

Number. DO NOT USE THIS UPSI if selection statements were created by the TSIDOFD

program.

If UPSI x1 is used with an execution of TSIDOFL where the TSIDOFL control statements

were NOT created by the TSIDOFD program, it becomes the user's responsibility to assure

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.

OUTPUT specifies a tape dataset to control the offload tape. This dataset must be cataloged.

If a label is not supplied for the OUTPUT dataset, TSIDOFL catalogs and uses the dataset

name OFFLOAD.DATA.SET.

IJSYSIN specifies that the control statements reside on a tape or disk dataset that was created

by the TSIDOFD program. You can use either standard VSE assignments or GDI.

PARM=’DLAUPD=NO’ can be specified on the EXEC Job Control statement or command to

prevent the current job name and date from being stored as the last accessed information for

each version read by the TSIDOFL program. By specifying PARM=’DLAUPD=YES’ or not

specifying the PARM operand, the current job name and date will be stored as the last

accessed information for each version read by the TSIDOFL program.

Use control statements to indicate which datasets to offload or backup. These can be

generated with TSIDOFD. Control statements for disk datasets versions identified in the

BIM-EPIC catalog and control statements for start-track-1 datasets cannot be mixed together

for input to the same execution of TSIDOFL.

If UPSI xx1 is used, control statements must not have been generated by the TSIDOFD

program.
