RE: Re[1]:AIX and Largefiles Performance

I'm still using 2G files, even though I've got big files enabled. You never know when you're going to come across something (e.g. /usr/bin/tar) that doesn't like files larger than 2G.. I have a relatively small (< 0.5TB) database though..

Thanks and Regards,
Prem.
