    Unanswered: TNS timeout from c# code


    Im new to Oracle.
    I have a C# code that connect to an Oracle DB.

    Application is running fine from my local machine.
    When I run the application from a win2003 server I get TNS-12535: TNSperation timed out occasionally (~4 out of 10 runs).

    I can connect the Oracle from this win2003 server using Toad and execute queries.
    I can tnsping the the Oracle from the and get ok response all time.

    What do you think can cause this problem?

    Thanks in advance,

    12535, 00000, "TNS:operation timed out"
    // *Cause: The requested operation could not be completed within the time out
    // period.
    // *Action: Look at the documentation on the secondary errors for possible
    // remedy. See SQLNET.LOG to find secondary error if not provided explicitly.
    // Turn on tracing to gather more information.
    I suspect that Oracle is victim; not culprit.
    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Good judgement comes from experience. Experience comes from bad judgement.
