We had a successfully running Oracle application & database servers running together on one Dell Poweredge 2950 on RHEL 4 until we were requested by the 3rd party vendors application folks to upgrade the Oracle application server. We attempted patching and then one patch led to another and another. Once the infastructure database was upgraded to 10.1.0.5.0, we could not get the opmn process to start.
I have now blown away everthing from /u01/app/oracle and reloaded from a backup before any patching began. Now everytime it gets to "opmnctl: starting opmn and all managed processes..." , the system just hangs and will not start.
All suggestions will be greatly appreciated.
