catalog备份数据库及RMAN存储脚本
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

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
