Hello RAC people, RAC 10.1.0.3 Tru64 5.1 TruCluster and CRS We have a 4 node 10.1.03 RAC cluster on Tru64 5.1b with CRS and TruCluster. During the last (and the only one after the CRS installation) CRS shutdown (not reboot), listener on 2 nodes came back up automatically and not on the other 2. The order of shutting down CRS was: NODE NAME: Time Order Node1 3:48pm 1 Node2 3:54pm 2 Node3 4:00:01pm 3 Node4 4:00:17pm 4 Listener on node3 and node4 came back up at 4:00:36pm and 4:00:41pm respectively. I always thought that the expected behavior is when you shutdown CRS, it will bring down all the services/instances/listeners registered and will not restart automatically "before you start CRS". If I am correct, why the listeners on node3 and node4 did come back up and if I am wrong, why the listeners on node1 and node2 didn't come up fine. I looked at the following files, but couldn't find anything too relevant: CRS_HOME/crs/log/* CRS_HOME/crs/crs/log/* CRS_HOME/crs/crs/init/* CRS_HOME/crs/crs/public/* CRS_HOME/crs/css/log/* CRS_HOME/crs/css/init/* CRS_HOME/crs/evm/log/* CRS_HOME/crs/evm/init/* CRS_HOME/crs/srvm/log/* CRS_HOME/crs/srvm/init/* CRS_HOME/crs/racg/dump/* $OH/racg/dump/* $OH/network/log/<listener_name>.log The only thing that I found unusual in crs logs was: Node1.log (similar in Node2.log): `ora.node1.ons` ran out of restarts on `node1` `ora.node1.ons` failed on `node1`, relocating. Cannot relocate `ora.node1.ons`. Stopping dependents Node3.log (similar in Node4.log): No entry like above!! Any ideas? Is "ONS" (and running ONSCA) "mandatory" and not "optional"? BTW, ONSCA did finish successfully at the time of installation. TIA, -Amit.
