Sorry for my OT, and thanks for the feedback to all of you. Thanks for taking in a good way. But I want to say it and know what you think about, I have it in my neck. And I think it was going to be useful for dbas, I hope it was. I always learn sharing what I think (even my stupid thinks) You know I'm the number one in ots, if you blockme I don't bother. And to end I'll including a fact: A customer can be extremely satisfied with a mediocre service, and can be disatisfied with a very good service, depending on several factors affecting his perception. About my english, first I have to end my book and learn a better oracle, I thinks this is more important, I have two projects non-ots I hope be useful for every one. But I'm going to fix it, I promess. And buy a site and a www.dba-ot.com. :) -- //www.freelists.org/webpage/oracle-l
