Selecting Datasets To Be Offloaded (TSIDOFD)
User Reference
Connectivity Systems, Inc.—Copyright © 2006
Use Pursuant to Company Instructions
13-19
Start Track 1 disk datasets are selected for backup using the following
criteria:
Pool name
Dataset name
Dataset names beginning with a specific character string
Datasets can be omitted from the inclusion list by:
Dataset name
Dataset names beginning with a specific character string
JCL
Requirements
The following is an example of the JCL requirements for using
TSIDOFD:
[// xLBL OUTPUT,'sysin.data.set']
//EXEC TSIDOFD
control statements
/*
An internal table is used during the dataset selection process to store each
selected dataset version. The capacity of this internal table depends on the
amount of excess partition storage available. The capacity, which can be
up to but does not include partition GETVIS storage, will never be less
than 100 entries. This internal table size is increased by approximately 21
entries for each 1K of excess partition storage available beyond the first
5K. For example, if SIZE=(TSIDOFD,50K) is specified on the EXEC
statement, then the internal table capacity will be about 1060 entries.
Specifying a SIZE operand value that results in 200K for partition
maximizes this internal table. For example, when utilizing a 2048K
partition, including GETVIS, a SIZE operand value of 1848K would be
appropriate.
If the Dataset Selection report is produced, the actual capacity of the
internal table for the current processing is stated on the second report
heading line. If TSIDOFD attempts to select more dataset versions than
can be held in the internal table, no output will be created. The program
will issue an EP618 message and terminate with a return code of 4.
UPSI Values There are no UPSI values.
Dataset
Requirements
The control statements created by TSIDOFD are created on SYSPCH if
SYS005 is assigned to SYSPCH. Otherwise, control statements can be
written to tape or disk by supplying a TLBL, DLBL, or DD with the DTF
name OUTPUT.
