To diagnose problems using DFSORT, you must be able to see the DFSORT messages
and control statements in the DWWSORT message data set.
DFSORT messages
start with 'ICE'. If you receive a condition code of 20 or do not see the DFSORT messages
and control statements, add the following to your change accumulation JCL:
//DWWSORT DD SYSOUT=A
and
resubmit your job.
If you still do not see the DFSORT messages and control statements
in the DWWSORT message data set, add the following to your change accumulation
JCL:
//SORTDIAG DD DUMMY
to force out the DFSORT messages
and control statements, and resubmit your job.
