Error - Oracle: ORA-12154: TNS
Am unable to connect to the Oracle Database. The error is - "Oracle: ORA-12154: TNS:could not resolve the connect identifier specified". Can anybody offer a solution. Thanks
Do you still need TNSnames file? or it will work without updating/adding connection to TNS file?
I tried the same and still getting the same error (Without any TNS Name file)
I don't believe you should need the TNSNames files ans that would be redundant. In the parameter, you are alredy providing what TNSNames file provides. You can update the TNSNames file to make use is TNSping to ensure that the connection is open.
