  • 1.  Problem with the prefetch buffer

    Posted Mar 28, 2007 08:01 AM
    In the log of ODBC connector to the database I obtain the next error. It only lets me introduce 24 machines.

    That's definitely interesting, but I believe the warning about the prefetch buffer is more just a performance warning, not an error; it shouldn't be blocking you from working with more than 24 machines. If you send me a copy of the ngserver.log file from your GSS console (to nigel dot bree at gmail dot com) then that may contain some diagnostic information from my code that will perhaps help me determine the cause of what you're seeing.

    The logfile may be very large, but it compresses really well so if you zip it up and attach the zip, it shouldn't be too big.
