The following error can occur when installing Oracle BI 11g on a windows platform and you are placing the Weblogic components on a shared drive (e.g. to install a "clustered" OBIEE environment):
[46153] The configuration file (O:\user_projects\lonbsobi01\bifoundation_domain\config\fmwconfig\jps-config.xml)was not found or is inaccessible.
This error is caused because the OPMN service does not know about the shared drive mapping (in the above example, the shared drive is O:\).
In order to fix, you have to prevent OPMN from starting up as a windows service:
1) Open up the [Middleware]\instances\instance1\bin\opmnctl.bat file for editing
2) Remove the following line from the file and then save:
set OpmnService=OracleProcessManager_instance1
3) Start up your OPMN processes using the opmnctl command-line (e.g. opmnctl startall)
