HPC1103W Duplicate log DSN.

Explanation
 The JCL presented for processing has defined a
SORT step with a log data set repeated with the DD DFSULOG concatenation.
The SORT step is marked not executable.

User response
 If the JCL was created by the DBRC GENJCL.CA
process, check the skeletal JCL member and variable settings that
were used. If the JCL was produced by a non-IMS process, change the
process to properly generate the DFSULOG DD concatenation into the
JCL for each SORT step.
If the IMS data sets are managed by DFSMS, refer to Preventing duplicate log DSN error.
