  • 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
    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
