• RMAN学习笔记之1:RMAN的登陆与登出


    一、登陆登出RMAN及相关注意点
    1、在oracle账户下,输入rman进入rman环境

    [oracle@ocpserver ~]$ rman
    Recovery Manager: Release 10.2.0.1.0 - Production on Thu Jun 20 20:15:25 2013
    Copyright (c) 1982, 2005, Oracle.  All rights reserved.
    RMAN> 

    2、输入connect target / 

    RMAN> connect target / 
    connected to target database 
    RMAN> 

    说明:

    connect target / 和在SQL*PLUS里面的sqlplus / as sysdba有类似的疑问。你也可以输入connect target user/passwd@instance_name 这样进入指定instance;

    当然这个命令可以汇总为直接输入rman target /
    connect不能像SQL*PLUS里面缩写为conn

    3、用rman启动oracle

    RMAN> startup;
    Oracle instance started
    database mounted
    database opened
    
    Total System Global Area     218103808 bytes
    Fixed Size                     1218604 bytes
    Variable Size                 96470996 bytes
    Database Buffers             117440512 bytes
    Redo Buffers                   2973696 bytes
    RMAN>

    4、用rman关闭oracle

    RMAN> shutdown immediate;
    using target database control file instead of recovery catalog
    database closed
    database dismounted
    Oracle instance shut down
    RMAN>

    5、暂时回到系统界面host
    如同SQL*PLUS里面的“!”符号作用一样。其实在SQL*PLUS里面也是可以使用host命令暂时退出SQL*PLUS,输入exit后回到SQL*PLUS欢迎一样。
    RMAN> host;
    [oracle@ocpserver ~]$ exit
    exit
    host command complete
    RMAN>

    6、RMAN界面下执行SQL命令
    ##RMAN不能执行select语句,郁闷
    语法: SQL '<command>' ;
    语法比较简单,就是提示符下输入SQL,后接SQL命令,命令用单引号括起来command 通常为可执行的SQL命令语句,也可以为PL/SQL块
    使用限制
    如果SQL语句中包含文件名,则文件名及路径需要使用两个单引号括起来,整个SQL语句首尾需要使用双引号
    可以执行SQL查询语句,但是无任何结果输出
    RMAN提示符下常用的命令

    • startup [nomount | mount], shutdown immediate
    • alter system archive log current
    • alter database open [resetlogs]

    RMAN> sql 'create table testrman(name varchar2(20),id number)';
    using target database control file instead of recovery catalog
    sql statement: create table testrman(name varchar2(20),id number)
    RMAN>

    RMAN> startup nomount;
    Oracle instance started
    Total System Global Area 218103808 bytes
    Fixed Size 1218604 bytes
    Variable Size 100665300 bytes
    Database Buffers 113246208 bytes
    Redo Buffers 2973696 bytes
    RMAN> alter database mount;
    using target database control file instead of recovery catalog
    database mounted
    RMAN> alter database open;
    database opened
    RMAN>

    二、登出RMAN

    国际惯例,exit,quit,自己试试也就知道了。

    三,参考深入学习文档
