  After the compare, the changed DDL in the APPLY job or in the
  Work Statement List (WSL) may cause the DB2 object to be
  in a different Pending state and the post utility sequence
  will group together/execute the following sequence:
  
  1 - CHECK DATA
  2 - REBUILD INDEX
  3 - REORG TABLESPACE.
  
  to remove the Pending status.
  
  However, when the TABLE SPACE and INDEX are both in
  REORG PENDING, REBUILD PENDING and CHECK PENDING states,
  we need to run REORG to first remove the REORG PENDING
  state, then other post utility statements can be executed
  successfully.  When the TABLE SPACE and INDEX is not in
  REORG PENDING state (for example, ADVISORY REORG PENDING,
  REBUILD PENDING and CHECK PENDING), a REBUILD INDEX,
  CHECK DATA and REORG TS is needed to remove the pending
  state.
  
  Considering this situation and the post utility statements are
  grouped together after all changed DDL for all the DB2 objects,
  the correct post utility sequence should be:
  
  1 - REORG to remove the REORG PENDING state (phase
      1 REORG)
  2 - REBUILD INDEX
  3 - CHECK DATA
  4 - REORG for non-REORG (like ADVISORY REORG PENDING)
      PENDING state (phase 2 REORG)
  

Problem conclusion

• The program has been changed to generate the following
  POST utility sequence :
  
  1 - REORG to remove the REORG PENDING state (phase
      1 reorg)
  2 - REBUILD INDEX
  3 - CHECK DATA
  4 - REORG for non-REORG (like ADVISORY REORG PENDING)
      PENDING state (phase 2 reorg)
