This article explains how to allow the XSUM keyword in a JCL SORT procedure.
Problem:
We are getting an "Invalid Operand Keyword" error when trying to use the XSUM parameter to write duplicate records to a separate file: SUM FIELDS=NONE,XSUM SORT104E: ******************* Invalid operand keyword 'XSUM' SORT015U: Command statement error(s) detected.
Resolution:
You need to turn on the SYNCSORT emulation in order to use this. To specify that you want to use SYNCSORT, set the environment variable MFJSENGINE=SYNCSORT in Configuration Information on the Server > Properties > General page for the enterprise server you are using. For example:
[ES-Environment]
MFJSENGINE=SYNCSORT
