RE: Oracle 9i refuses to allow client connection -- I need

Stephen

   Technet (aka. otn) is good, but sometimes it helps to have a book help you get started. Consider picking up a copy of Oracle9i DBA 101. http://www.amazon.com/exec/obidos/tg/detail/-/0072224746/qid=1059408389/sr=8 -1/ref=sr_8_1/002-8977984-5541669?v=glance&s=books&n=507846 Don't worry too much about Windows vs. Unix. There is very little with Oracle that is Windows or Unix specific. Most of the differences relate to file naming and starting/stopping the instance. Pretty much any of the books give you the syntax for each system where there is a difference.

   Actually, you are probably fortunate with your training being delayed for a few months. The class covers so much in a few days that if you are really new to Oracle it is hard to comprehend everything. By messing with it for a few months, the class will make a lot more sense.

Thanks for the encouragement and yes I would like to know some of the good Oracle 101 under a windows environment books. I'm pretty certain that my approved training will be funded with year-end money, but that means the earliest I'll get to class is in late October or early November.

Hope you don't mind me bugging you all a while until I get squared away.
