Juan, I don't have a paper, but I do have several database where my files are larger the 1G. Works fine. There were problems in the past. But I never had any problems. I'm running on 8.1.7 on Windows NT.

Hi list Please my customer received one email asking to resize a datafile and he said "According to the email you sent the datafile affected has a size more than 1gb, that could be causing the problem, because windows operating system has problems managing datafiles bigger than 1GB. .... This information is not official." I think this is definitively wrong, but I don't have nothing official to say do you have please some paper demonstrating that this seems to me ridiculous or I'm wrong and this is true. Thanks a lot.
