oracle 学习笔记 Rman脚本（windowns）

Rman脚本（windowns）
1、RMAN 命令参数：

C:\>rman ;;;
-----一般敲错这个提示才会出来。
Argument Value Description
-----------------------------------------------------------------------------
target quoted-string connect-string for target database
catalog quoted-string connect-string for recovery catalog
nocatalog none if specified, then no recovery catalog
cmdfile quoted-string name of input command file
log quoted-string name of output message log file
trace quoted-string name of output debugging message log file
append none if specified, log is opened in append mode
debug optional-args activate debugging
msgno none show RMAN-nnnn prefix for all messages
send quoted-string send a command to the media manager
pipe string building block for pipe names
timeout integer number of seconds to wait for pipe input
checksyntax none check the command file for syntax errors
-----------------------------------------------------------------------------
2、编写批处理：

rman target sys/admin@orcl catalog rman/rman@rman cmdfile 'c:\temp\rmandk.sql' log 'c:\temp\rman_backup_"%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%".log' append checksyntax

---cmdfile 'c:\temp\rmandk.sql' 指我们执行批处理通过cmdfile调用rmanbk.sql运行RMAN脚本内容。

---log 指定日志的存放位置。
---append 指日志以追加方式写入
--- checksyntax 检查语法是否有误。

3、测试:

恢复管理器: Release 10.2.0.1.0 - Production on 星期五 5月 18 21:28:37 2012
Copyright (c) 1982, 2005, Oracle. All rights reserved.
连接到目标数据库: HUNT (DBID=719233105)
连接到恢复目录数据库
RMAN> run {
2> allocate channel ch01 device type disk;
3> allocate channel ch02 device type disk;
4> resync catalog;
5> sql 'alter system archive log current';
6> backup as compressed backupset incremental level 0 database format='e:\rman\Oracle10g_%d_data_0_%T_%U.rman' tag='Level_0_data';
7> sql 'alter system archive log current';
8> backup archivelog all delete all input format ='e:\rman\Oracle10g_%d_archivelog_0_%T_%U.rman';
9> DELETE NOPROMPT OBSOLETE;
10> sql 'alter system archive log current';
11> release channel ch01;
12> release channel ch02;
13> }
-----以上为rmanbk.sql的内容。
此 cmdfile 不存任何在语法错误
恢复管理器完成。
----加上checksyntax 仅做语法检查，不做实际备份。
生成如下日志: rman_backup_20120518.log
4、写入恢复目录：

可以将脚本保存在恢复目录当中，操作如下：

RMAN> create script rmanbackup_0 {
2> allocate channel ch01 device type disk;
3> allocate channel ch02 device type disk;
4> resync catalog;
5> sql 'alter system archive log current';
6> backup as compressed backupset incremental level 0 database format='e:\rman\Oracle10g_%d_data_0_%T_%U.rman' tag='Lev
l_0_data';
7> sql 'alter system archive log current';
8> backup archivelog all delete all input format ='e:\rman\Oracle10g_%d_archivelog_0_%T_%U.rman';
9> DELETE NOPROMPT OBSOLETE;
10> sql 'alter system archive log current';
11> release channel ch01;
12> release channel ch02;
13> }
created script rmanbackup_0

5、运行脚本：

Rman> run {
execute script rmanbackup_0;
}

批处理调用时只需修改rmanbk.sql ：

C:\TEMP>type rmandk.sql
run {
execute script rmanbackup_0;
}
6、修改脚本：

Rman>print script rmanbackup_0 to file ‘c:\temp\rmanbackup_0’;
script rmanbackup_0 written to file c:\temp\rmanbackup_0
修改完成后执行：

RMAN> replace script rmanbackup_0 from file 'c:\temp\rmanbackup_0';
script commands will be loaded from file c:\temp\rmanbackup_0
replaced script rmanbackup_0
7、查看脚本：

RMAN> print script rmanbackup_0;
printing stored script: rmanbackup_0
{allocate channel ch01 device type disk;
backup as compressed backupset incremental level 0 database format='e:\rman\Oracle10g_%d_data_0_%T_%U.rman'
release channel ch02;
}

RMAN> list script names;
List of Stored Scripts in Recovery Catalog
Scripts of Target Database HUNT
Script Name
Description
-----------------------------------------------------------------------
rmanbackup_0

以下脚本为本地脚本，仅当前数据库可用，我们可以通过以下命令创建全局脚本。
RMAN> Create global script glscr_01 {
2> Backup database;
3> }
created global script glscr_01
RMAN> list global script names;
List of Stored Scripts in Recovery Catalog
Global Scripts
Script Name
Description
-------------------------------------------
glscr_01
执行：
Rman> run {
execute global script glscr_01;
}
8、删除脚本：

RMAN>delete [global] script rmanbackup_0本文出自 “HUNT” 博客，请务必保留此出处http://hunt1574.blog.51cto.com/1390776/863422
