Hi

One important difference in NT cannot write to open files..so for backups you gotta to use ocopy,

for killing session you need to use orakill at the os level

learn about ms toolkit

You can install cygwin and make NT behave as Unix (well sorta of)

Batch scripting isnt as rich Unix shell scripting

Learn how to use Oradim

And windows if you want to start a database the oracle service has to be up n running

windows does not have a mailx utility ..but you can download blat search for it on google..

And the most important thing..when all else fails JUST REBOOT THE SERVER..AND EVERYTHING WILL START WORKIN FINE..(I DONT KNOW WHY THIS IS ALWAYS TRUE)and this can be a differentiating factor when you come from a Unix background
