file_name format a60
SYS@userdata>column tablespace_name format a20
SYS@userdata>select tablespace_name,file#,file_name,v.status,v.enabled from dba_data_files d,v$datafile v where d.file_id=v.file#;
TABLESPACE_NAME FILE# FILE_NAME STATUS ENABLED
-------------------- ---------- ------------------------------------------------------------ --------------------- ------------------------------

UNDOTBS1 2 /u01/app/oracle/oradata/userdata/undotbs01.dbf ONLINE READ WRITE
SYSAUX 3 /u01/app/oracle/oradata/userdata/sysaux01.dbf ONLINE READ WRITE
USERS 4 /u01/app/oracle/oradata/userdata/users01.dbf ONLINE READ WRITE
EXAMPLE 5 /u01/app/oracle/oradata/userdata/example01.dbf ONLINE READ WRITE
将users表空间设置为只读,尝试修改只读的表空间
SYS@userdata>column file_name format a60 SYS@userdata>column tablespace_name format a20 SYS@userdata>alter tablespace users read only; SYS@userdata>select tablespace_name,file#,file_name,v.status,v.enabled from dba_data_files d,v$datafile v where d.file_id=v.file#; TABLESPACE_NAME FILE# FILE_NAME STATUS ENABLED -------------------- ---------- ------------------------------------------------------------ --------------------- ------------------------------ SYSTEM 1 /u01/app/oracle/oradata/userdata/system01.dbf SYSTEM READ WRITE UNDOTBS1 2 /u01/app/oracle/oradata/userdata/undotbs01.dbf ONLINE READ WRITE SYSAUX 3 /u01/app/oracle/oradata/userdata/sysaux01.dbf ONLINE READ WRITE USERS 4 /u01/app/oracle/oradata/userdata/users01.dbf ONLINE READ ONLY EXAMPLE 5 /u01/app/oracle/oradata/userdata/example01.dbf ONLINE READ WRITE
SYS@userdata>update scott.emp set sal=sal+1; update scott.emp set sal=sal+1 * ERROR at line 1: ORA-00372: file 4 cannot be modified at this time ORA-01110: data file 4: ‘/u01/app/oracle/oradata/userdata/users01.dbf‘
将表空间重新设置为只读
SYS@userdata>alter tablespace users read write;
2.表空间脱机
SYS@userdata>alter tablespace users offline; Tablespace altered. SYS@userdata>select tablespace_name,file#,file_name,v.status,v.enabled from dba_data_files d,v$datafile v where d.file_id=v.file#; TABLESPACE_NAME FILE# FILE_NAME STATUS ENABLED -------------------- ---------- ------------------------------------------------------------ --------------------- ------------------------------ SYSTEM 1 /u01/app/oracle/oradata/userdata/system01.dbf SYSTEM READ WRITE UNDOTBS1 2 /u01/app/oracle/oradata/userdata/undotbs01.dbf ONLINE READ WRITE SYSAUX 3 /u01/app/oracle/oradata/userdata/sysaux01.dbf ONLINE READ WRITE USERS 4 /u01/app/oracle/oradata/userdata/users01.dbf OFFLINE DISABLED EXAMPLE 5 /u01/app/oracle/oradata/userdata/example01.dbf ONLINE READ WRITE SYS@userdata>update scott.emp set sal=sal+1; update scott.emp set sal=sal+1 * ERROR at line 1: ORA-00376: file 4 cannot be read at this time ORA-01110: data file 4: ‘/u01/app/oracle/oradata/userdata/users01.dbf‘ SYS@userdata>alter tablespace users online; Tablespace altered.
