APAR status

  • Closed as program error.

Error description

  • An hanging situation can occur during the unload
    of LOB data into a spanned dataset (SPANNED YES option)..
    
    This can occur regardless of the processing (native or SQL)
    mode, during any unload of LOB data into a spanned dataset but
    its probability increases with the number of NULL values and
    inline LOB data in the involved LOB data.
    

Local fix

  • as the issue is less likely in SQL mode, consider specifying DB2
     FORCE if the issue occurs with an unload run in native mode.
