Hard to believe you have not turned up relevant advice. This kind of question has been asked and answered a whole bunch of times on the internet. Yes even on cdos a bunch of times.
I have not tried searching cdos with the google groups interface for a while ... it used to work pretty well.
The Oracle documentation is pretty good here. Have you looked at it?
Other places to check are the Oracle forums for the database area or asktom ... Received on Thu May 27 2010 - 15:40:53 CDT
