【脚本】Oracle控制文件移动增加删除多路复用

Oracle维护控制文件Controlfile相关脚本（移动增加删除多路复用操作）

?

-- 1-当数据库使用PFILE参数文件时，使用该方式维护控制文件
-- 1.1查看当前数据库使用的参数文件类型

SQL> SHOW PARAMETER PFILE;
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /home/oracle/product/11gR2/dbs/spfileora11g.ora

?

SQL> SHOW PARAMETER SPFILE;
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /home/oracle/product/11gR2/dbs/spfileora11g.ora

?
-- 1.2查看当前的数据库控制文件布局状况

SQL> SELECT NAME FROM V$CONTROLFILE;
 
NAME
--------------------------------------------------------------------------------
/home/oracle/product/oradata/ora11g/control01.ctl
/home/oracle/product/fast_recovery_area/ora11g/control04.ctl

/home/oracle/backup/controlfile/control05.ctl
/home/oracle/backup/controlfile/control06.ctl
/home/oracle/backup/controlfile/control07.ctl
 
7 rows selected

?

SQL> SELECT VALUE FROM V$PARAMETER WHERE NAME = ‘control_files‘;
 
VALUE
--------------------------------------------------------------------------------
/home/oracle/product/oradata/ora11g/control01.ctl, /home/oracle/product/fast_rec

?
-- 1.3关闭数据库并且修改动态参数文件PFILE(如果当前数据库使用的PFILE参数文件)

SQL> shutdown immediate

?

control_files=("/home/oracle/product/oradata/ora11g/control01.ctl", 
               "/home/oracle/product/fast_recovery_area/ora11g/control04.ctl",

               "/home/oracle/backup/controlfile/control06.ctl")

?
-- 1.4在操作系统层面多路复制控制文件,使得和规划相一致

-- 1.5使用PFILE参数文件启动数据库

-- 1.6根据PFILE参数文件创建SPFILE文件

SQL> CREATE SPFILE FROM PFILE;

?
-- 1.7使用静态参数文件重启数据库

SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP

?
-- 2-当数据库使用SPFILE参数文件时，使用该方式维护控制文件
-- 2.1查看当前数据库使用的参数文件类型

SQL> SHOW PARAMETER PFILE;
