RE: working with datafile > 2Gb in HadHat 7.3

There is no such hardware limitation like that. Those are the OS i.e. software limitations. For instance, the 2gb file size limit is because of the
32 bit OS, actually, to be more specific, it's the 32 bit file system. You can have a 32bit OS kernel, but if your file system supports 64bit, then you can support >2gb files. Same thing for the memory.

OK. I stand corrected. You do need third party tools though. But I suppose engineers can always hack their way through hardware limitations to make thing work. Like the >4GB memory limit of intels - this is not more since I believe Windows 2K and XP have this feature(in software?) where it can access greater than 4GB memory..
