The error message that in the description comes from the HttpMethodDirectory and that is part of the communication with VDSM, not related to the database. What makes you think that this is problem related to the database? Juan, there were DB issues at the log, I suspected due to that Backend bean was not deployed, so Dafna could not perform a login. The bug is about connecting from UI to the engine, and not about the communication with VDSM (which is another issue in the environment). Attaching the part that raises my suspicion - VdsCpuVdsLoadBalancingAlgorithm] (QuartzScheduler_Worker-13) [10d9037c] VdsLoadBalancer: number of over utilized vdss found: 0. 2013-06-18 11:04:03,859 INFO [org.ovirt.engine.core.bll.VdsCpuVdsLoadBalancingAlgorithm]2013-06-18 12:28:08,213 ERROR [org.ovirt.engine.core.utils.ejb.EJBUtilsStrategy] (ServerService Thread Pool -- 41) Error looking up resource DATA_SOURCE 2013-06-18 12:28:08,216 ERROR [org.ovirt.engine.core.dal.dbbroker.DbFacadeLocator] (ServerService Thread Pool -- 41) Unable to locate DbFacade instance: java.lang.RuntimeException: Datasource is not defined at org.ovirt.engine.core.dal.dbbroker.DbFacadeLocator.<clinit>(DbFacadeLocator.java:34) [engine-dal.jar:] at org.ovirt.engine.core.dal.dbbroker.DbFacade.getInstance(DbFacade.java:212) [engine-dal.jar:] at org.ovirt.engine.core.bll.Backend.checkDBConnectivity(Backend.java:126) [engine-bll.jar:] at org.ovirt.engine.core.bll.Backend.create(Backend.java:120) [engine-bll.jar:] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [rt.jar:1.7.0_09-icedtea] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) [rt.jar:1.7.0_09-icedtea] According to the stack trace in comment 2 I would say that this is a duplicate of 879904. *** This bug has been marked as a duplicate of bug 879904 *** |
