Copying and Merging Datasets (TSIDDTD)
Description TSIDDTD is a dataset-to-dataset copy/merge utility program. You can
use TSIDDTD to copy a single dataset or to merge multiple input datasets
into a single output dataset. TSIDDTD uses standard LIOCS access
methods enabling BIM-EPIC to completely control the input and output
datasets.
TSIDDTD supports any sequential dataset with a fixed, variable,
spanned, or undefined record format. However, TSIDDTD can only
process tape datasets that follow the standard LIOCS format conventions.
See “
Tape Formats Supported,” for additional information.
TSIDDTD performs one copy operation per execution. To copy a
multi-file tape, execute TSIDDTD once for every dataset on the tape. You
must include input and output labels for each dataset.
Configuration
Options
To use TSIDDTD for disk datasets, the GDI=YES configuration option
must be specified.
JCL
Requirements
The following is an example of the JCL requirements.
input dataset label(s)
output dataset label
// EXEC TSIDDTD
[optional control statements ]
/*
UPSI Values There are no UPSI values.
Dataset
Requirements
You must submit a label for one output dataset and at least one input
dataset. The default DTF names are INPUT and OUTPUT, but you can
specify the use of other DTF names in your control statements.
The output dataset block size will be the same as the input dataset block
size unless you specify a new block size in the output dataset definition.
Uncontrolled disk datasets can be reblocked using option code B=n on the
DLBL statement.
When copying uncontrolled datasets, use SYS005 for output dataset and
SYS004 for input dataset.
If more than one input dataset is copied to the output dataset, specify
option code T for every input dataset label except the last dataset label.
Using option code T, you can merge tape and disk versions into a single
dataset. If all input is on the same device type, you can also use the
BIM-EPIC DD statement concatenation feature.
