for some old unix system that doesn't support large file ( large than 2G) , then the choice is 2G ,
but even for some system such as Windows 2000, in theory , it can support a very very large file ( TB or more ? , I forgot the number) , I also just use 4GB as long as the database is not larger than 100 GB, that means we only need to manage 25 datafile.
there uses to be a bug in 8i that when the data file autoextend to larger than 4GB, Oracle may crash. but I don't know any other bugs about file size larger than 4GB.
Some people say small file ( <= 4GB) is better for backup and recovery , also easy to assign to different disks etc.
Friends, could you share with your experience on this ?
but may be in future with the 10G ASM function , this is no longer relevant any more. |
