Error description

  • The DB2 Connector auto generated syntax for the DB2 LOAD
    utility can lead to concurrency issues if multiple DataStage
    jobs are invoked to write to specific partitions for the same
    paritioned table using the DB2 Connector "Partition number"
    property.
    
    The issue occurs due to specifying LOAD RESUME, rather than
    PART integer RESUME, which causes LOAD to serialize on the
    entire tablespace, thus inhibiting concurrent processing of
    separate partitions.
    
    Please note that the correct LOAD syntax is generated when the
    DB2 Connector "Partition number" property is not utilized

Problem summary

  • DB2 CONNECTOR JOBS THAT WRITE TO DB2 FOR Z OS CAN ABORT WHEN RUN
     IN PARALLEL WHILE USING STAGE PARTITION NUMBER PROPERTY.
    

Problem conclusion

  • The DB2 Connector auto generated syntax for the DB2 LOAD utility
     can lead to concurrency issues if multiple DataStage jobs are
    invoked to write to specific partitions for the same paritioned
    table using the DB2 Connector "Partition number" property.
    
    
    The issue occurs due to specifying LOAD RESUME, rather than PART
    integer RESUME, which causes LOAD to serialize on the entire
    tablespace, thus inhibiting concurrent processing of separate
    partitions.
    
    Please note that the correct LOAD syntax is generated when the
    DB2 Connector "Partition number" property is not utilize.
    
    With this fix, connector will generate correct LOAD syntax
      when the DB2Connector "Partition number" property is utilized.
