Error description

  • When unloading from image copies referenced in the Db2 catalog
    (COPYDDN LAST_IC/-integer option), Db2 HPU should automatically
    disable parallelism whenever at least two non cataloged image
    copy data sets involved in the unload are stored on the same
    tape.
    The LDS parallelism should be disabled when the two image copies
    stored on the same tape are the partition's image copies of a
    single partitioned tablespace.
    The TS parallelism should be disabled when the two image copies
    stored on the same tape are image copies of distinct table
    spaces involved in the same UNLOAD statement.
