    you may need to increase open_cursors init.ora parameter.

    To get over credential problem.

    Open the sqlnet.ora and look for statements like

    sqlnet.crypto_seed = "some text"

    and comment out these lines using a "#" sign.

    Once you have eliminated all of the impossible,
    whatever remains however improbable,
    must be true.
