Error description

  • A LOAD with fourteen INTO ... PART X clauses.   Thirteen of the
    SYSRECs are defined with  DD DUMMY . The job output shows
    PARTITIONS WILL BE LOADED IN PARALLEL, NUMBER OF TASKS = 6
    
    The first six parts processed (parts 1-6) had DD DUMMY input and
    completed showing
    NUMBER OF INPUT RECORDS PROCESSED=0
    
    The job abended processing the next set of 6 parts.  Five with
    DD DUMMY and one with an actual data set to load.
    
    
    The problem can occur when a load subtask loaded at least two
    partitions and the LRECL for first partition is smaller than
    the following ones'. It is because DB2 used to allocate the
    record work area for a subtask using the LRECL of the first
    partition as buffer length. When the record length of the next
    partition assigned to this task is bigger than the LRECL,
    then overlay will happen.

    ****************************************************************
    User ran a LOAD FORMAT DELIMITED INTO TABLE PART X INDDN utility
    with partition parallelism. When one of the load subtask was
    assigned two partitions and the LRECL of the input dataset for
    the first partition is smaller than the second one, an overlay
    happened which caused ABENDS0C4 RC00000038 at
    DSNURPLD + x'23C4'.
    
    The reported problem was caused by the LOAD utility not
    allocating a sufficiently large enough work area for record
    processing.
    
    Additional symptom: DSNUGSTB + x'1508'
    

Problem conclusion

  • The LOAD partition parallelism code has been modified to
    allocate a sufficiently large work area for FORMAT DELIMITED
    processing
