环境说明：

提前配置好两个库的监听与tnsnames.ora
IP：10.100.25.13 为目标数据库  
IP：10.100.25.14 为恢复目录数据库（catalog database）

以下操作全部都在恢复目录数据库下执行：

1.为恢复目录创建一个表空间，表空间名称是 catalogts。用户名是catalogdemo 密码是
oracle。给这个用户赋予恢复目录拥有者权限。

SQL> create tablespace catalogts datafile'/home/oracle/app/oradata/catalog01.dbf' size 50m autoextend on;

Tablespace created.

SQL> create user catalogdemo identified by oracle default tablespace catalogts quota unlimited on catalogts;

User created.

SQL> grant recovery_catalog_owner to catalogdemo;

Grant succeeded.

2.使用RMAN用catalogdemo用户连接到恢复目录数据库。在 catalogts 表空间中创建恢复目录。

[oracle@11g ~]$ rman catalog catalogdemo/oracle@10.100.25.14:1521/orcl

connected to recovery catalog database

RMAN> create catalog tablespace catalogts;

recovery catalog created

3.使用RMAN，连接到目标数据库和恢复目录数据库。

[oracle@11g ~]$ rman target sys/oracle@10.100.25.13:1521/orcl catalog catalogdemo/oracle@10.100.25.14:1521/orcl

Recovery Manager: Release 11.2.0.1.0 - Production on Thu Dec 4 14:56:21 2014

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to target database: ORCL (DBID=1388303183)
connected to recovery catalog database

5.在恢复目录中注册目标数据库，执行resync catalog 命令来同步控制文件和恢复目录。

RMAN> register database;

database registered in recovery catalog
starting full resync of recovery catalog
full resync complete

RMAN> resync catalog;

starting full resync of recovery catalog
full resync complete

RMAN> list incarnation;

List of Database Incarnations
DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time
------- ------- -------- ---------------- --- ---------- ----------
2       21      ORCL     1388303183       PARENT  1          15-AUG-09
2       4       ORCL     1388303183       CURRENT 945184     09-OCT-14

catalog RMAN存储脚本

脚本的分类
    local : 在rman连接的目标数据库下创建的脚本，此类脚本仅仅适用于当前目标数据库。即是针对特定的数据库创建的rman脚本
    global : 能够在恢复目录注册的任意目标数据库中执行
    如：create global script XXXX comment 'A script for full backup to be used with any database' {。。。。}

a:  创建rman本地存储脚本
RMAN> create script whole_backup { backup database; }

created script whole_backup

b：执行rman本地存储脚本
RMAN> run { execute  script whole_backup; }

executing script: whole_backup

c:  查看当前恢复目录内的脚本
list [global | all] script names
       
RMAN> list script names;

d:  更新脚本
    replace [global] script scrip_name {....}
    replace [global] script script_name from file '<dir>'  --从文件更新脚本

RMAN> replace  script whole_backup { allocate channel ch1 type disk;
allocate channel ch2 type disk;
backup incremental level 0 database plus archivelog  delete input
format '/home/oracle/rmanbak/db_%d_%U'
tag=db_inc_0;
release channel ch1;
release channel ch2; }2> 3> 4> 5> 6> 7>

replaced script whole_backup

e:  查看脚本内容
RMAN> print script whole_backup;

printing stored script: whole_backup
{ allocate channel ch1 type disk;
allocate channel ch2 type disk;
backup incremental level 0 database plus archivelog  delete input
format '/home/oracle/rmanbak/db_%d_%U'
tag=db_inc_0;
release channel ch1;
release channel ch2; }

f： 删除脚本
delete [global] script script_name
