Error description

  • We have observed file I/O overhead with SI/SFG when using
    a mounted document storage filesystem. A significant
    amount of time is spent on native unix I/O operations (within
    the getCanonicalPath() method) that could potentially be
    eliminated by either caching or using other methods. (eg.
    getAbsolutePath).
    The particular code affected is in:
    com.sterlingcommerce.woodstock.workflow.BaseDocument,
    and the method is getNewOutputFile().
    

Local fix

Problem summary

  • Users Affected:
    All
    
    Problem Description:
    There is a performance issue within Sterling B2B Integrator
    and Sterling File Gateway with regard to time spent on I/O
    operations.
    
    Platforms Affected:
    All
    

Problem conclusion

  • Resolution Summary:
    The paramter getAbsolutePath has been added to
    jdbc.properties.in.
    By default it is set to false. By setting it to true the user
    enables IBM Sterling B2B Integrator to use the Java
    getAbsolutePath method instead of getCanonicalPath when creating
    documents under FS storage. This improves performance.
