OBIEE 11g Error: Unable to start coreapplication_obips1 component

While OBIEE presentation server is not up and running you will get below messages:

Error 500–Internal Server Error
From RFC 2068 Hypertext Transfer Protocol — HTTP/1.1:
10.5.1 500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.

Just check the status of all OBIEE components using opmnctl command as below
F:\MiddlewareHome\instances\instance1\bin>opmnctl status

All the components are alive except coreapplication_obips1.

Processes in Instance: instance1
ias-component | process-type | pid | status
coreapplication_obiccs1 | OracleBIClusterCo~ | 1160 | Alive
coreapplication_obisch1 | OracleBIScheduler~ | 1604 | Alive
coreapplication_obijh1 | OracleBIJavaHostC~ | 5484 | Alive
coreapplication_obips1 | OracleBIPresentat~ | N/A | Down
coreapplication_obis1 | OracleBIServerCom~ | 1236 | Alive

Also EM log showing error message below:

Failed to get messages for target /Farm_bifoundation_domain

Also the diagnostic log shows below:

EM-02694    Supplementary information regarding operation:

There may be various reason to it and one of the obvious reason is Loop-back adapter not configured for DHCP client .

The another main reason is any mistake at ‘instanceconfig.xml’ file .Any mistake in instanceconfig.xml tag placement could cause the issue of BIPS not starting up properly .Just correct the issue if did any changes and try to restart the service individually from EM UI .

Hope this could help somebody as it is very difficult to dig into issue just because of the junk OBIEE log file 😦 So tip is , do think and not blindly incorporate !!
