Hi please, Because memory constraints we are thinking to move from x32 to x64 windows 2003 enterprise edition. I read we'll have to reformat, is there another important point to think about when migrating the server or Oracle 10g?. Thank you :) -- ---------------------------------------- http://www.oracleboliviaspecialists.com/ Oracle Certified Profesional 9i 10g Oracle Certified Professional Developer 6i 10 years of experience from Oracle 7 to Oracle10g and developer 6i
