This question reminds me of the "Not knowing how to ask for help" section of Tom Kyte's UKOUG 2009 presentation. One of his responses shown was this one: http://bit.ly/7CTybt Followup October 7, 2009 - 7am Central time zone: my car won't start. I won't tell you anything else - now please tell me why it's happening and the solution for it. I won't tell you what errors I'm seeing on the dashboard. I won't tell you what noise it is or is not making. I won't tell you what version of car I'm using. I won't tell you what roads I'm driving it on (think OS) Help us help you: provide enough detail so people can understand the issue.
