    The DeploymentManager status cache code tries to refresh its
    information about applications by calling
    the Application mbean in its servant.  If the
    websphere.ws390.servant.started notification
    has not been received yet at the control region, then this may
    cause exceptions in the control region:
    BBOO0222I: ADMN0007I: The getAttribute method results in
    exception
    com.ibm.websphere.management.exception.AdminException:
    javax.management.MBeanException: Exception thrown in

    com.ibm.ws.management.status.DeploymentManagerStatusCache.refres
    hCache(DeploymentManagerStatusCache.java:762)
    There may also be an FFDC log created which shows:

    In another case, the TraceService MBean proxy code was also
    noticed to have the same issue with InstanceNotFoundException.

Problem conclusion

  • The code has been modified to wait for
    websphere.ws390.servant.started notification.
    
    APAR PM38627 is currently targeted for inclusion in Service
    Level (Fix Pack) 6.1.0.41 of WebSphere Application Server V6.1.
    and Fix Pack 8.0.0.1 of WebSphere Application Server V8.0.
    
    Sysroute APAR PM46035 will be used to deliver this fix in
    WebSphere Application Server V7.0.
