Error description

  • "(HPU 5.2 and HPU 6.1)
    A Db2 HPU job terminates with an ABEND U1129 R=00000001 under
    the following conditions:
    
    - The unload is performed in native mode
    - LOB and/or XML columns are unloaded
    - The unload requires an encoding scheme conversion
    
    The likelihood of this ABEND occurring depends on the objects
    contained within the tablespace and the occurrence cannot be
    predicted beforehand.
    

Local fix

  • Perform the unload in SQL mode with DB2 FORCE
