Re: Unable to login error

Hi @harryishs,


Regarding the error message "Oracle: ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA", the issue should be caused by Oracle client is not installed, or if it is not configured properly. If it is installed, you will want to verify the tnsnames.ora file is properly configured and you are using the proper net_service_name. See:


You can also take a look at jmiridium 's suggestion in this similar thread Connect To Oracle Database .
