Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V7.0 * * * **************************************************************** * PROBLEM DESCRIPTION: During the Deployment Manager * * startup, the Control Region may * * receive a * * javax.management.MBeanException, and * * FFDC recorded * * javax.management.InstanceNotFoundExcept * * ion. These do not * * indicate operational issues * * as subsequent mbean calls work * * fine after servant.started is * * received. * * * **************************************************************** * RECOMMENDATION: * **************************************************************** 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 RequiredModelMBean while trying to invoke operation getName at com.ibm.ws.management.AdminServiceImpl.getAttribute(AdminService Impl.java:763) at com.ibm.ws.management.AdminServiceImpl.getAttribute(AdminService Impl.java:708) at com.ibm.ws.management.status.DeploymentManagerStatusCache.refres hCache(DeploymentManagerStatusCache.java:762) There may also be an FFDC log created which shows: Caused by: javax.management.InstanceNotFoundException: Non-existant servant00000E2000000001 at com.ibm.ws390.management.ServantMBeanInvoker.getServantMBeanAttr ibute(ServantMBeanInvoker.java:1494) at com.ibm.ws390.management.ServantMBeanInvoker.getAnyServantMBeanA ttribute(ServantMBeanInvoker.java:1355) at com.ibm.ws390.management.ProxyMBeanSupport.mbeanGetterSimple(Pro xyMBeanSupport.java:957) at com.ibm.ws390.management.proxy.ServantMBeanInvokerProxy.mbeanInv okerSimple(ServantMBeanInvokerProxy.java:1077) at com.ibm.ws390.management.proxy.ServantMBeanInvokerProxy.invoke(S ervantMBeanInvokerProxy.java:939) In another case, the TraceService MBean proxy code was also noticed to have the same issue with InstanceNotFoundException. javax.management.InstanceNotFoundException: Non-existant servant0000039000000003 at com.ibm.ws390.management.ServantMBeanInvoker.invokeServantMBean( ServantMBeanInvoker.java:1046) at com.ibm.ws390.management.ServantMBeanInvoker.invokeAnyServant(Se rvantMBeanInvoker.java:856) at com.ibm.ws390.management.ServantMBeanInvoker.invokeSpecificServa nt(ServantMBeanInvoker.java:467) at com.ibm.ws390.management.proxy.TraceServiceMBeanProxy$SetRuntime TraceSpecification.run(TraceServiceMBeanProxy.java:1246)
Problem conclusion
The code has been modified to wait for websphere.ws390.servant.started notification. APAR PM46035 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.19 of WebSphere Application Server V7.0. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
