Error description

  • SAP BI 7
    BW PACK 4.2.1
    DS 7.5.2
    HPUX 11.X
    
    They have a couple of ds jobs which loads data into BW . The
    jobs are being called from BW and use the same source system.
    One job seems to process multiple data packets and the other
    job is process data packet sequentially.
    
    Want to be able to enable parallelism in BW load stage.
    

Local fix

  • NA
    

Problem summary

  • Loading large amounts of data is too slow when using the
    Sequential Execution mode.
    

Problem conclusion

  • Enabled BW Load stage to run in parallel.
    Note: the recommended job configuration is BW Load stage with
    one input link - this will allow the engine maximum flexibility
    to partition the load.
    
    Please note the following environment variable is introduced:
    
    ASC_BWLOAD_NODE_SYNC_TIMEOUT - Timeout (in seconds) for all
    nodes/links to register for a Parallel load. Increase this value
    for complex loads. Default is 10 seconds.
    
    IMPORTANT NOTE:
    ===============
    There are some limitations for cleanup of temporary files in
    case of job abort on PX. In order to maximize the cleanup
    capabilities the following
    patch should be installed: JR34990.
    Even with patch JR34990 installed there are still a couple of
    scenarios when the cleanup will not occur (e.g. when forcefully
    stopping a running job in
    DS Director or when the job aborts because of a stage other than
    the BW stage). In that case the user has to manually run the
    cleanup utility after job
    aborts (otherwise the next job run may not work correctly,
    hanging on execution or producing unexpected results)
    
    Description of the cleanup tool (jobReset):
    
    If the BW Load job aborts, it may be necessary to cleanup the
    temporary files by running the jobReset utility.
    Open a command prompt window to the DS Server and:
    - source dsenv
    cd <IIS Install Folder>/Server/DSEngine
    . ./dsenv
    
    - run the job reset utility
     cd $DSSAPHOME/DSBWbin
    ./jobReset  <Connection Name> <Source System> <InfoSource>
    <InfoSource Type> <JobName>
    
    where  <InfoSource Type> = MASTER | MASTERTEXT | TRANSACTION |
    MASTERHIERARCHY
    
    for example:
    cd  /hpithome/IBM/InformationServer/Server/DSBWbin
    ./jobReset SAPBW8 PACK09 IS1 MASTER bwload
    
    You should get a confirmation message: "jobReset - Successful"
