归档和非归档模式下ORA-01145错误的解决方法

Oracle 作者:xulongxc 时间:2014-04-08 14:34:15 0 删除 编辑
总结了一下,在归档和非归档的场景下,ora-01145这个错误可能有如下三种情况:
1.off line tablespace
--在非归档模式下尝试ofline 数据文件
SQL> alter tablespace tools offline immediate;
alter tablespace tools offline immediate
*
ERROR at line 1:
ORA-01145: offline immediate disallowed unless media recovery enabled
 
以上操作需要在归档模式下才可以。
SQL> archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     244
Next log sequence to archive   246
Current log sequence           246
SQL> alter tablespace tools offline immediate;
Tablespace altered.
--在非归档模式下可以采用如下
SQL> alter tablespace tools offline;
Tablespace altered.
 
2.offline datafile
SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline;
alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline
*
ERROR at line 1:
ORA-01145: offline immediate disallowed unless media recovery enabled
--在归档模式下,直接offline数据文件就可以

SQL> alter database datafile  '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline ;
Database altered.
--而在非归档模式下,需要先把表空间给offline掉,然后才能offline数据文件,可以参见如下的实例。
 
3.offline drop
误删数据文件后,这个需要 alter database datafile xxxxx offline drop;
 
 
 
--关于测试环境
库为10g 10.2.0.1.0  非归档模式
 
表空间情况如下:
SQL> select tablespace_name,status from dba_tablespaces;
TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
SYSAUX                         ONLINE
TEMPTS1                        ONLINE
TBS1                           ONLINE
TBS3                           ONLINE
TEMP1                          ONLINE
TEMP2                          ONLINE
TOOLS                          ONLINE
OMF1                           ONLINE
UNDOTBS2                       ONLINE
数据文件情况如下:
SQL> select name,status from v$datafile;
NAME
--------------------------------------------------------------------------------
STATUS
-------
/u01/app/oracle/oradata/disk_4/system01.dbf
SYSTEM
/u01/app/oracle/oradata/disk_4/sysaux01.dbf
ONLINE
/u01/app/oracle/oradata/disk_1/tbs01.dbf
ONLINE

NAME
--------------------------------------------------------------------------------
STATUS
-------
/u01/app/oracle/oradata/disk_2/tbs02.dbf
ONLINE
/u01/app/oracle/oradata/disk_3/tbs03.dbf
ONLINE
/u01/app/oracle/oradata/disk_3/tbs3.dbf
ONLINE

NAME
--------------------------------------------------------------------------------
STATUS
-------
/u01/app/oracle/oradata/disk_4/undotbs2.dbf
ONLINE
/u01/app/oracle/oradata/disk_5/tools.dbf
ONLINE
/u01/app/oracle/oradata/disk_5/PODD/datafile/o1_mf_omf1_88ygncsw_.dbf
ONLINE

9 rows selected.
--我尝试将数据文件tbs01给offline掉
SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline;
alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline
*
ERROR at line 1:
ORA-01145: offline immediate disallowed unless media recovery enabled
 
但是操作失败,我记得平时都好好的,怎么就不行了。
--查看错误解析
SQL> !oerr ora 01145
01145, 00000, "offline immediate disallowed unless media recovery enabled"
// *Cause: ALTER TABLESPACE ... OFFLINE IMMEDIATE or ALTER DATABASE DATAFILE
//         ... OFFLINE is only allowed if database is in ARCHIVELOG mode.
// *Action:Take tablespace offline normally or shutdown abort. Reconsider your
//         backup strategy. You could do this if you were archiving your logs.
 
我这个库是非归档的,
 
SQL> alter tablespace tbs1 offline;
Tablespace altered.
SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline;
Database altered.
