Hi,

Can anybody explain me the difference between DYNALLOC vs SORTWKnn in SORT. Also which is better to use and why??
I saw the manual also but not able to understand the exact difference.
I ran the test job also using both the options but not able to make up which is optimum to use for large volume of input datasets.
Please help.

Thanks,
Anand.

DYNALLOC allows DFSORT to dynamically allocate work data sets as needed and thus allows for more flexibility. SORTWKnn DD statements allocate the work space before DFSORT is invoked.

We recommend using DYNALLOC rather than specifying SORTWKnn DD statements.
