Oracle数据库文件路径变更
环境：CentOS 7.7 + Oracle 11.2.0.4
1.检查所有文件的绝对路径
- 查看数据文件、临时文件、日志文件、控制文件当前目录
SQL> select name from v$datafile;
NAME
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/u01/app/oracle/oragata/ora11g/system01.dbf
/u01/app/oracle/oragata/ora11g/sysaux01.dbf
/u01/app/oracle/oragata/ora11g/undotbs01.dbf
/u01/app/oracle/oragata/ora11g/users01.dbf
SQL> select name from v$tempfile;
NAME
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/u01/app/oracle/oragata/ora11g/temp01.dbf
SQL> select member from v$logfile;
MEMBER
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/u01/app/oracle/oragata/ora11g/redo01.log
/u01/app/oracle/oragata/ora11g/redo02.log
/u01/app/oracle/oragata/ora11g/redo03.log
SQL> select name from v$controlfile;
NAME
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
/u01/app/oracle/oragata/ora11g/control01.ctl
/u01/app/oracle/oragata/ora11g/control02.ctl
- 查看参数文件
[oracle@weblog dbs]$ ll
total 20
-rw-rw---- 1 oracle oinstall 1544 Dec 17 14:42 hc_ora11g.dat
-rw-r--r-- 1 oracle oinstall 2851 May 15 2009 init.ora
-rw-r----- 1 oracle oinstall 24 Dec 17 14:24 lkORA11G
-rw-r----- 1 oracle oinstall 1536 Dec 17 14:24 orapwora11g
-rw-r----- 1 oracle oinstall 2560 Dec 17 14:42 spfileora11g.ora
- 创建spfile
SQL> create pfile from spfile;
File created.
[oracle@weblog dbs]$ ll
total 24
-rw-rw---- 1 oracle oinstall 1544 Dec 17 14:42 hc_ora11g.dat
-rw-r--r-- 1 oracle oinstall 2851 May 15 2009 init.ora
-rw-r--r-- 1 oracle oinstall 876 Dec 17 14:49 initora11g.ora
-rw-r----- 1 oracle oinstall 24 Dec 17 14:24 lkORA11G
-rw-r----- 1 oracle oinstall 1536 Dec 17 14:24 orapwora11g
-rw-r----- 1 oracle oinstall 2560 Dec 17 14:42 spfileora11g.ora
2.关闭实例
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
3.创建新目录
[oracle@weblog dbs]$ cd /u01/app/oracle/
[oracle@weblog oracle]$ ll
total 0
drwxr-x--- 3 oracle oinstall 28 Dec 17 14:24 admin/
drwxr-x--- 6 oracle oinstall 80 Dec 17 14:42 cfgtoollogs/
drwxr-xr-x 2 oracle oinstall 10 Dec 17 14:14 checkpoints/
drwxrwxr-x 11 oracle oinstall 168 Dec 17 14:09 diag/
drwxr-xr-x 2 oracle oinstall 10 Dec 17 14:21 oradata/
drwxr-x--- 3 oracle oinstall 28 Dec 17 14:24 oragata/
drwxrwxr-x 3 oracle oinstall 28 Dec 17 13:48 product/
4.修改控制文件
- 在pfile中更改控制文件地址
[oracle@weblog oracle]$ cd $ORACLE_HOME/dbs
[oracle@weblog dbs]$ more initora11g.ora
ora11g.__db_cache_size=3456106496

- 用修改过控制文件目录的参数文件启动数据库至mount
SQL> startup pfile='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initora11g.ora' nomount;

控制文件必须真实存在在参数文件记录的地址中
报错原因：需要将控制文件移至要修改的目录下
[oracle@weblog dbs]$ cp /u01/app/oracle/oragata/ora11g/control01.ctl /u01/app/oracle/oradata/ora11g/control01.ctl
cp: cannot create regular file ‘/u01/app/oracle/oradata/ora11g/control01.ctl’: No such file or directory
！注意，要提前创建好目录
[oracle@weblog dbs]$ cd /u01/app/oracle/oradata/
[oracle@weblog oradata]$ mkdir ora11g
[oracle@weblog oradata]$ ll
total 0
drwxr-xr-x 2 oracle oinstall 10 Dec 17 15:02 ora11g/

[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/control02.ctl /u01/app/oracle/oradata/ora11g/control02.ctl
- 重新mount数据库
SQL> alter database mount;
Database altered.
5.修改数据文件、日志文件、临时文件
SQL> alter database rename file '/u01/app/oracle/oragata/ora11g/system01.dbf' to '/u01/app/oracle/oradata/ora11g/system01.dbf';
alter database rename file '/u01/app/oracle/oragata/ora11g/system01.dbf' to '/u01/app/oracle/oradata/ora11g/system01.dbf'
*
ERROR at line 1:

ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3
！错误原因同上
- 将数据文件、日志文件等移动到目标目录下
[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/system01.dbf /u01/app/oracle/oradata/ora11g/system01.dbf
[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/sysaux01.dbf /u01/app/oracle/oradata/ora11g/sysaux01.dbf
[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/undotbs01.dbf /u01/app/oracle/oradata/ora11g/undotbs01.dbf

[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/temp01.dbf /u01/app/oracle/oradata/ora11g/temp01.dbf
[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/redo01.log /u01/app/oracle/oradata/ora11g/redo01.log
[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/redo02.log /u01/app/oracle/oradata/ora11g/redo02.log
[oracle@weblog oracle]$ cp /u01/app/oracle/oragata/ora11g/redo03.log /u01/app/oracle/oradata/ora11g/redo03.log
- rename数据文件、日志文件等
SQL> alter database rename file '/u01/app/oracle/oragata/ora11g/system01.dbf' to '/u01/app/oracle/oradata/ora11g/system01.dbf';
Database altered.
SQL> alter database rename file '/u01/app/oracle/oragata/ora11g/sysaux01.dbf' to '/u01/app/oracle/oradata/ora11g/sysaux01.dbf';
Database altered.

控制文件已经卸载参数文件里了，不需要rename
SQL> alter database rename file '/u01/app/oracle/oragata/ora11g/control01.ctl' to '/u01/app/oracle/oradata/ora11g/control01.ctl';
