OID is Down For Ambiguous Reasons

Posted on by Osama Mustafa in Fusion Middleware
Today one of the customer called complaining about accessing to the system and how its not working ? Since everything is configured as single sign on (SSO) first thing to check was OID or oracle internet Directory.

The logs indicate to the below error :-

[2015-05-01T07:00:18+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: [oidmon]: Unable to connect to database,
will retry again after 10 sec

[2015-05-01T07:00:28+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: Connecting to database, connect string is oiddb

[2015-05-01T07:00:28+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: [gsdsiConnect] ORA-12514, ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.

from the above error the OID is unable to connect to database server i checked database and listener everything is up without any issue and all the other application working without any issues.

after investigation I checked the sqlnet.ora and add the following :-

SQLNET.AUTHENTICATION_SERVICES= (NONE)
NAMES.DIRECTORY_PATH= (TNSNAMES)

Restart the services and everything is working.

maybe this solution will not lead or help in so many cases i am working to know why this will effect on OID since it’s was working without any issues for 1 year

Thanks
