Exploiting the System Sort Utility
Probably the best dataset copy utility available to you will be your
system SORT utility. A lot of effort is put into tuning the CPU and I/O
performance of the SORT and it will normally perform very well as a copy
utility. Most types of dataset formats will be supported; refer to the
documentation for your SORT product for any restrictions.
The SORT utility is also capable of producing multiple copies or even
extracting multiple subsets of the same input dataset in a single pass.
Simple Data Analysis
The SORT utility can also be used to
for one or more specified fields.
- identify records with duplicate keys
- count the number of unique key values
- perform simple tabular reports
Loading VSAM Keyed Datasets
Since SORT can output to VSAM datasets and keyed datasets can be loaded
more efficiently when sorted by the key value, why not use SORT when
loading VSAM keyed datasets?
