手工冷备份脚本

首先了解各种set值含义，参考：http://blog.csdn.net/rlhua/article/details/11849883

RMAN脚本：http://blog.csdn.net/rlhua/article/details/12714647

手工热备份脚本：http://blog.csdn.net/rlhua/article/details/11850629

 

 

1、新建两个目录，分别为cold_bak和hot_bak，分别用作冷备份和热备份转储的位置。

[oracle@rtest oracle]$ cd bak

[oracle@rtest bak]$ mkdir cold_bak

[oracle@rtest bak]$ mkdir hot_bak

[oracle@rtest bak]$ pwd

/u01/app/oracle/bak

[oracle@rtest bak]$ ls

cold_bak  hot_bak

2、冷备份，即拷贝数据文件和控制文件到新的位置，转储。

首先查看需要备份的数据文件和控制文件的位置。

sys@TEST0910> select name from v$datafile order by 1;

NAME

----------------------------------------------------------------------------------------------------

/u01/app/oracle/oradata/test0910/example01.dbf

/u01/app/oracle/oradata/test0910/sysaux01.dbf

/u01/app/oracle/oradata/test0910/system01.dbf

/u01/app/oracle/oradata/test0910/testtb.dbf

/u01/app/oracle/oradata/test0910/undotbs01.dbf

/u01/app/oracle/oradata/test0910/users01.dbf

6 rows selected.

sys@TEST0910> select name from v$controlfile order by 1;

NAME

----------------------------------------------------------------------------------------------------

/u01/app/oracle/fast_recovery_area/test0910/control02.ctl

/u01/app/oracle/oradata/test0910/control01.ctl

3、拼SQL语句。执行操作系统拷贝命令。

•   数据文件的拷贝命令

sys@TEST0910> set verify on

sys@TEST0910> select 'host cp ' ||name|| ' &bakdir' from v$datafile order by 1;

Enter value for bakdir: /u01/app/oracle/bak/cold_bak

old   1: select 'host cp ' ||name|| ' &bakdir' from v$datafile order by 1

new   1: select 'host cp ' ||name|| ' /u01/app/oracle/bak/cold_bak' from v$datafile order by 1

'HOSTCP'||NAME||'/U01/APP/ORACLE/BAK/COLD_BAK'

----------------------------------------------------------------------------------------------------

host cp /u01/app/oracle/oradata/test0910/example01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/sysaux01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/system01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/testtb.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/undotbs01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/users01.dbf /u01/app/oracle/bak/cold_bak

6 rows selected.

• 控制文件的拷贝命令

sys@TEST0910> select 'host cp ' ||name|| ' &bakdir' from v$controlfile order by 1;

Enter value for bakdir:  /u01/app/oracle/bak/cold_bak

old   1: select 'host cp ' ||name|| ' &bakdir' from v$controlfile order by 1

new   1: select 'host cp ' ||name|| '  /u01/app/oracle/bak/cold_bak' from v$controlfile order by 1

'HOSTCP'||NAME||'/U01/APP/ORACLE/BAK/COLD_BAK'

----------------------------------------------------------------------------------------------------

host cp /u01/app/oracle/fast_recovery_area/test0910/control02.ctl  /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/control01.ctl  /u01/app/oracle/bak/cold_bak

• 冷备脚本：

[oracle@rtest bak]$ vi cold_bak.sql

set echo off trimspool off heading off feedback off verify off time off

set pagesize 0 linesize 200

define bakdir='/u01/app/oracle/bak/cold_bak'

define bakscp='/u01/app/oracle/bak/cold_cmd.sql'

spool &bakscp

select 'host cp ' ||name|| ' &bakdir' from v$datafile order by 1;

select 'host cp ' ||name|| ' &bakdir' from v$controlfile order by 1;

spool off

shutdown immediate

@&bakscp

startup

• 执行冷备脚本：

sys@TEST0910> @/u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/example01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/sysaux01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/system01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/testtb.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/undotbs01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/users01.dbf /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/fast_recovery_area/test0910/control02.ctl /u01/app/oracle/bak/cold_bak

host cp /u01/app/oracle/oradata/test0910/control01.ctl /u01/app/oracle/bak/cold_bak
