表空間基本操作
create tablespace users
datafile '/opt/ora9/oradata/big58/users01.dbf' size 26M autoextend on
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
//這樣的表空間段空間是手動管理的
drop tablespace users including contents and datafiles;
連物理檔案一起刪除。
create tablespace users
datafile '/opt/ora9/oradata/big58/users01.dbf' size 26M autoextend on
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
alter tablespace users add
2 datafile '/opt/ora9/oradata/big58/users02.dbf' size 20M;
alter tablespace users offline;
//在作業系統下刪除users02.dbf
alter tablespace users online;
alter tablespace users online

ERROR at line 1:
ORA-01157: cannot identify/lock data file 9 - see DBWR trace file
ORA-01110: data file 9: '/opt/ora9/oradata/big58/users02.dbf'
quote:
最初由 huakaibird 釋出
表空間有8，9兩個資料檔案，刪除9。
由於表空間是offline的，所以生成的trace檔案檔案中沒有該表空間的datafile 8和9,
在trace檔案中新增未刪除的表空間資料檔案8，alter database open resetlogs,會報 file 8（未刪除的） was not restored from a sufficiently old backup。然後dba_data_files中兩個資料檔案變成MISSING00008，MISSING00009。
