TSN <num>:<num> contains DDL information that cannot be
  optimized

  Explanation:  The identified transaction contains an AIJ record
  with DDL information.  DDL information cannot be optimized and
  forces a flush of the accumulated SORT information.  Too many of
  these operations limit the effectiveness of the resulting
  optimized after-image journal and decrease the overall
  optimization performance.
