Hey Joan, > Do you know if window 2003 x64bit is certified for 11g 64 bit. I checked > the platform on metalink, there is no entry for Microsoft Windows 2003 > (x64), I asked our os system, he said the server is not AMD64/EM64T, nor > Itanium, just x64. Do you have any idea if it is available? Are your co-workers sure about that??? http://www.tech-faq.com/em64t.shtml If you're still in-doubt, contact your Oracle Sales Rep who should be able to find out for you. HTH! GL!
