Thread: ORA-12545 Pls. help.. unable to connect to server

    Hi all,

    I am unable to connect to the Oracle server from a client. I am able to use SQL Plus in the server. But unable to connect from a client machine.

    I get an error ORA-12545: Connect failed because target host or object does not exist

    Can any of you help? I tried restarting the server. I thought there would be some network problem and so the host couldn't be found. But when I stop the listener I get the error No listener.. so the server is being addressed properly. The port is also right... I couldn't figure out any reason...

    Help of any level would be greatly appreciated....

    Thanks in advance...

    Check the tnsnames.ora file on your client machine to see whether it had been configured correctly.

    Then try

    tnsping servicename


    sqlplus username/password@servicename
