Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V6.1.0 using multiple applications   *
    *                  accessing the same JNDI name to look up a   *
    *                  cache instance.                             *
    ****************************************************************
    * PROBLEM DESCRIPTION: JNDI cache look ups fail after a        *
    *                      NameAlreadyBoundException occurs on a   *
    *                      JNDI cache look up.                     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When a NameAlreadyBoundException occured during a JNDI cache
    look up the dynacache service removes references to the cache.
    When an applcation performs another cache look up it fails
    with IllegalStateException because the references to the cache
    were removed.
    

Problem conclusion

  • When a NameAlreadyBoundException occurs dynacache will not
    destroy references to the cache and subsequent look ups will
    succeed.
    
    APAR PM29178 is currently targeted for inclusion in
    Service Level (Fix Pack) 6.1.0.39 of WebSphere Application
    Server V6.1
