ADB7400I Object compare prepends SYSTEM PATH names SYSIBM, SYSFUN, SYSPROC, and SYSIBMADM in the SET PATH statement of the compare source if SYSTEM PATH names are not explicitly specified in the compare source.

  Explanation
Db2® Object Comparison Tool detected a
   PATHSCHEMAS change, and therefore added the listed SYSTEM PATH names. Db2 11 and later uses these SYSTEM PATH names
   for an unqualified PATH value. Thus, prepending these SYSTEM PATH names does not alter the PATH
   value that you specified in the compare source.
