First, your datafile is already 2000M, so you don¹t need to resize it: 2097152000B / 1024 = 2048000K / 1024 = 2000M Second, since the datafile is already at its max size, why bother turning autoextend on at all? alter database datafile '/oracle/sub/datafile4/psub_1/psub_datafile1.dbf' AUTOEXTEND OFF; If you do want autoextend on for whatever reason, you can change its maxsize without resizing the datafile: alter database datafile '/oracle/sub/datafile4/psub_1/psub_datafile1.dbf' AUTOEXTEND ON NEXT 20M MAXSIZE 2000M; On 11/22/06 4:12 AM, Kean Jacinta wrote: > Sorry , there are some mistake .
