APAR status

  • Closed as program error.

Error description

  • The beanmanager is currently not cached.  The lack of a cache
    for these objects is causing a measurable performance impact
    between JAXRS 1.1 and JAXRS 2.0 in WebSphere Application
    Server V9.

    *                      to the lack of a cache for              *

    ****************************************************************
    The IBM performance team identified a sizable performance hit
    to JAXRS 2.0 applications when migrating from JAXRS 1.1.
    Investigation discovered that BeanManager objects were not
    being cached/reused and this contributed significantly to
    the observed performance hit.
    

Problem conclusion

  • The code was changed to cache and reuse the BeanManager
    objects.  This change was tested and verified by the IBM
    WebSphere Application Server performance team.
    
    The fix for this APAR is targeted for inclusion in fix pack
    9.0.5.5. For more information, see 'Recommended Updates for
    WebSphere Application Server':
