    Arrow Unanswered: ORA-12571 TNS:packet writer failure

    hi everybody,

    I am new to oracle, i have installed oracle91 on win2000 server family and i installed 6i on client (not the same system). when i runs forms and try to connect to server it throws "ORA-12571 TNSacket writer failure" error. i have reinstalled my server and client .

    When i run eay config app from client and try to make configuration file on test service tab, it throws same error.

    I can connect to server from LAN. but can't from oracle form's

    Hoping for quick response.

    Try check that no other computer on the network has the same IP address as the machine on which the problem has been reported.
    Check allert.log for ORA-600 errors.
    Also check your computer for network colisions
    Try to set the directive DISABLE_OOB=TRUE in the sqlnet.ora file.
    Try to disable antivirus automatic protection if is some antivirus sw installed on computer.
    Try to add tcp.nodelay = yes to yor protocol.ora

    If will be ok, let us know...

    Hi,

    Check the tnsnames.ora file . In that look for port address & Ipaddress.
