Error description

  • Business Object mappings in BPEL can demonstrate poor

    PROBLEM SUMMARY:
    Business Object mappings in BPEL can demonstrate poor
    performance or excessive memory usage when put under load or
    when using complex mappings. To improve performance under
    these conditions, module classloader-level caching of the XSL
    templates that execute the mappings was introduced.
    

Problem conclusion

  • The code was altered to better utilize caching in the
    transform service.
    
    The code fix was targeted to be included in the following fix
    packs:
    7.5.1 Fix Pack 2 (v7.5.1.2)
    8.0.1 Fix Pack 2 (v8.0.1.2)
