oracle移动数据文件
1.链接到数据库
[oracle@linux]$ sqlplus /nolog
SQL> conn / as sysdba
2. 查看数据文件位置
SQL> select file_name from sys.dba_data_files;
或
SQL> select name from v$datafile;
FILE_NAME
------------------------------------------------------------------------
/oradata/PMPTGDB/users01.dbf
/oradata/PMPTGDB/undotbs01.dbf
/oradata/PMPTGDB/sysaux01.dbf
/oradata/PMPTGDB/system01.dbf
/oradata/PMPTGDB/work.dbf

2. 关闭数据库
SQL> shutdown immediate;

4. 移动文件到新的位置(好比新的位置为/media/hdd1/oradata/PMPTGDB )
cd /oradata/PMPTGDB/
mv users01.dbf undotbs01.dbf sysaux01.dbf system01.dbf work.dbf /media/hdd1/oradata/PMPTGDB

5. 以mount模式启动数据库
SQL> startup mount;
SQL> alter database rename file 'C:\APP\WANGXW\ORADATA\ORCL\MYMOTIF_TS.DBF' to 'D:\oradata\orcl\MYMOTIF_TS.DBF';
对每个要移动的文件重复执行上面的alter database rename file ... to ...

6. 打开数据库
SQL> alter database open;
再次查看文件位置，发现已经更该。java

第 1 行出现错误:
ORA-01125: 没法禁用介质恢复 - 文件 1 设置了联机[url=]备份[/url]
ORA-01110: 数据文件 1: 'G:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\SYSTEM01.DBF'linux

SQL>
是在归档模式下出现的问题,
解决办法是:sql

conn / as sysdba
startup mount
recover datafile "select name from v$datafile;" ;
alter databae open;

EXAMPLE 100 78.75 21.25 21.25%

确认文件：
select file_name,bytes/1024/1024 from dba_data_files where tablespace_name like 'UNDOTBS1';
检查UNDO Segment状态
select usn,xacts,rssize/1024/1024/1024,hwmsize/1024/1024/1024,shrinks from v$rollstat order by rssize;app

一、建立一个新的小空间的undo tablespace
create undo tablespace UNDOTBS2 datafile 'D:\oradata\orcl\UNDOTBS02.DBF' size 150m autoextend off;url

二、设置新的表空间为系统undo_tablespace
alter system set undo_tablespace=UNDOTBS2;

3.等待原UNDO表空间全部UNDO SEGMENT OFFLINE
select usn,xacts,status,rssize/1024/1024/1024,hwmsize/1024/1024/1024,shrinks from v$rollstat order by rssize;
四、删除旧的表空间
alter tablespace UNDOTBS1 offline;
drop tablespace UNDOTBS1 including contents and datafiles;
5.检查空间状况
往后增长数据文件方法
ALTER TABLESPACE UNDOTBS2 ADD DATAFILE 'D:\oradata\orcl\UNDOTBS03.DBF' size 150M reuse AUTOEXTEND ON;

询回滚段状况(原undo表空间的回滚段所有offline,能够删除相关表空间)
select tablespace_name,segment_name,status from dba_rollback_segs;

离线原undo表空间
alter tablespace undotbs1 offline;

肯定原undo回滚段所有offline,直接删除
drop tablespace undotbs1 including contents and datafiles;

六、其余方法
禁止undo tablespace自动增加
alter database datafile 'C:\APP\WANGXW\ORADATA\ORCL\UNDOTBS01.DBF' autoextend off;
扩大undo tablespace的大小：
alter database datafile 'C:\APP\WANGXW\ORADATA\ORCL\UNDOTBS01.DBF' resize 200m;

system表空间满:
其解决的方法有两个：
1）扩SYSTEM表空间，或者清理SYS.AUD$表；安装数据库时报以下错误：

ORA-00604:ERROR occurred at recursive SQL level 1
ORA-01653:unable to extend table SYS.AUD$ by 8192 in tablespace SYSTEM
ORA-02002:ERROR while writing to audit trail
ORA-00604:ERROR occurred at recursive SQL level 1
ORA-01653:unable to exten table SYS.AUD$ by 8192 in tablespace SYSTEM
WARNING:You are no longer connected to ORACLE.
SQL>SP2-0640:Not connected

报system系统表空间不足

能够使用以下语句查询system表空间中什么对象占用空间最大：

select SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024 from dba_segments where TABLESPACE_NAME='SYSTEM' and rownum < 10 order by BYTES/1024/1024 desc;

并对其进行分析，看system表空间过大的问题。

但如上显示的错误信息已经直接说明：一是：数据库的审计功能已经开启（SYS.AUD$表，只有开了审计功能才会向其中插入数据），如何开启和关闭oracle数据库中的审计功能？

扩展表空间能够参考以下方法：

方法一：手动重设并增长表空间tbsk的数据文件大小

SQL> alter database datafile '/opt/oracle/oradata/ora11g/system.dbf' resize 20G;

方法二：把表空间的数据文件设为自动增加(不建议使用此方法)

SQL> alter database datafile '/opt/oracle/oradata/ora11g/system.dbf' autoextend on next 10M maxsize unlimited;

一个表空间数据库文件最大能够扩展到32G。

方法三：增长新的数据文件(建议使用此方法)

SQL> alter tablespace system add datafile '/opt/oracle/oradata/ora11g/system2.dbf' size 10G autoextend off;

下面语句清理审计表，释放系统表空间：

sqlplus / as sysdba

truncate table SYS.AUD$;

2）关闭审计功能：（关闭审计须要从新启动Oracle）

SQL> show parameter audit
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
audit_file_dest                      string      /oracle/app/admin/ora11g/adump
audit_sys_operations                 boolean     TRUE
audit_syslog_level                   string
audit_trail                          string      DB  -->说明已经开启审计功能
SQL>

执行下面SQL：

SQL>alter system set audit_trail=none scope=spfile;

直接使用spfile文件中的审计功能参考audit_trail为none，即关闭审计功能。

执行完后，重启数据库。

启动后查看：

SQL> show parameter audit_trail

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
audit_trail string NONE

SYSTEM表空间如今又能插入数据了。

oracle 删除表空间及数据文件方法

oracle 关闭audit 功能

http://zxf261.blog.51cto.com/701797/762048

Oracle 11g缺省安装数据库启动了audit功能，致使oracle不断累积sys.aud$表及相关索引数据量增长；
若是致使表空间满了，在alert日志中将会报ORA-1654: unable to extend index SYS....错误。
若是不用到审计功能，建议关闭审计。

处理过程：
一、用oracle用户登陆到数据库服务器，执行：
sqlplus / as sysdba
二、取消audit，将初始化参数audit_trail设置为NONE
alter system set audit_trail=none scope=spfile;
三、而后重启数据库.
shutdown immediate;
sqlplus / as sysdba
startup;
四、删除签权数据，oracle用户登陆到数据库服务器：
sqlplus / as sysdba
truncate table SYS.AUD$;

关闭审计功能：
 sqlplus / as sysdba
 SQL> alter system set audit_trail=none scope=spfile;
 SQL> shutdown immediate;
 SQL> startup;
 SQL> truncate table SYS.AUD$;
