netbackup 7.5.0.7 之oracle数据库的备份和恢复

Oracle数据库的数据结构

Oracle的文件系统主要分为四大部分：
1） 控制文件
2） 数据文件
3） 日志文件
4） 其他文件（如参数文件，密码文件等）
前三种文件系是Oracle文件系统的主要组成部分，一般在以下路径可以找到：
$ORACLE_HOME$\oradata\orcl
.CTL文件为控制文件
.DBF 文件为数据文件
.LOG 文件为日志文件
除了前三种文件还有一种参数文件，参数文件不是数据库系统中的有效组成部分，在启动数据库时，参数文件不直接参与工作，只是控制文件是由参数文件寻找的。参数文件位置：
$ORACLE_HOME$\admin\orcl\pfile
1.1.1 挂载裸LUN 1、 挂载裸LUN，mount到/nbubakcup。
1.1.2 确认安装环境 1、确认磁盘空间
在AIX/Linux环境中，/usr/openv目录下需要3GB以上的剩余空间。
2、解析相关服务器主机名与备份通信的ip地址
我们需要在/etc/hosts文件中添加本机及Master Server的主机名及IP地址。
3、确认Media Server已经正确识别磁带驱动器及磁带库
运行lsdev –Cc tape命令查看Media Server已经正确识别磁带库与磁带驱动器。
包括老带库及新带库。
1.1.3 安装NetBackup Media Server for AIX (Linux) 将NetBackup安装介质中标签为DVD3的DVD放入的P570A的光驱，
n 安装Media Server程序
运行install程序安装Media Server，过程如下：（红色为修改注意项）

新建存储单元；输入名称，介质服务器选择ssadb，目录的绝对路径名输入ssadb上裸lun路径（例如：/nbubackup66）。如下图。

第一章 安装Client端程序

1.1、前期准备
将客户端软件直接上传至AIX/Linux主机的/tmp目录,使用gzip -d和tar -xvf命令解压缩后进行安装;
1.2、安装步骤
Linux、Solaris和Aix上的安装步骤类似，进入对应系统的目录。

root# ./install Symantec Installation Script Copyright 1993 - 2012 Symantec Corporation, All Rights Reserved.

Enter the name of the NetBackup server : prd-nbu7 Would you like to use "sacnsun02102" as the configured name of the NetBackup client? [y,n] (y) y

验证查看是否生成了/usr/openv/netbackup目录 # ls -l /usr/openv/netbackup

第二章 配置Oracle备份

在NBU7.5客户端里已经包含了oracle客户端，接下来就是配置了。
2.1、建立连接

[root@localhost ~]# su - oracle [oracle@localhost ~]$ cd /usr/openv/netbackup/bin [oracle@localhost bin]$ ./oracle_link 2012年 08月 25日 星期六 09:43:28 CST All Oracle instances should be shutdown before running this script. Please log into the Unix system as the Oracle owner for running this script Do you want to continue? (y/n) y LIBOBK path: /usr/openv/netbackup/bin ORACLE_HOME: /orcl/oracle Oracle version: 10.2.0.1.0 Platform type: i686 Linking LIBOBK: ln -s /usr/openv/netbackup/bin/libobk.so /orcl/oracle/lib/libobk.so Done Please check the trace file located in /tmp/make_trace.4459 to make sure the linking process was successful.

2.2、创建备份脚本

[root@localhost ~]# mkdir -p /usr/openv/netbackup/script [root@localhost ~]# cd /usr/openv/netbackup/ext/db_ext/oracle/samples/rman [root@localhost rman]# ls cold_database_backup.sh database_restore.sh hot_tablespace_backup.sh cold_duplex_database_backup_full.sh hot_database_backup.sh pit_database_restore.sh [root@localhost rman]# cp hot_database_backup.sh /usr/openv/netbackup/script/ [root@localhost rman]# cd /usr/openv/netbackup/script/ [root@localhost script]# ls hot_database_backup.sh [root@localhost script]# mv hot_database_backup.sh rman.sh [root@localhost script]# chmod o+x rman.sh 一定要授权执行权限,否则NBU调用不了 [root@localhost script]# vi rman.sh

第三章 创建备份策略

3.1 选择策略类型和存储位置



3.2 创建备份策略



Frequency: 备份周期 Retention: 保留周期


策略时间表，默认的Default-Application-Backup不要随意更改，一般只更改保留周期。
3.3 选择备份客户端



3.4 选择备份脚本



3.5 执行备份策略

第四章 本机数据文件恢复

关闭数据库：
Sqlplus / as sysdba
shutdown immediate 立即关闭
4.1 删除数据文件
[root@orcl ～]# cd /u01/app/oracle/oradata/orcl
[root@orcl orcl]# rm -rf *.dbf
[root@orcl orcl]#
4.2 恢复数据文件
[oracle@orcl oradata]$ rman target /
RMAN> shutdown abort;
RMAN> startup mount;
connected to target database (not started)
Oracle instance started

4> send 'NB_ORA_SERV=master';
5> restore database;
6> recover database;
7> release channel ch00;

4.3 验证恢复效果

-rw-r-----. 1 oracle oinstall 5251072 8月 24 17:19 users01.dbf
可以看到删除的数据文件都已经恢复

第五章 本机控制、系统数据文件恢复

5.1 系统数据文件恢复
在删除了所有数据文件的情况下，需要先单独恢复系统的数据文件。
run {
allocate channel ch00 type 'sbt_tape';
send 'NB_ORA_CLIENT=szdbtest';
send 'NB_ORA_SERV=prd-nbu7';
restore datafile 1;
recover datafile 1;
release channel ch00;
sql 'alter database open';
}
run {
allocate channel ch00 type 'sbt_tape';
send 'NB_ORA_CLIENT=szdbtest';
send 'NB_ORA_SERV=prd-nbu7';
restore datafile 2;
recover datafile 2;
release channel ch00;
sql 'alter database open';
}
5.2全库恢复
再执行全库恢复即可。
run {
allocate channel ch00 type 'sbt_tape';
send 'NB_ORA_CLIENT=szdbtest';
send 'NB_ORA_SERV=prd-nbu7';
restore database;
recover database;
release channel ch00;
sql 'alter database open';
}

第六章 恢复控制文件

在测试环境中，发现控制文件出现了问题；恢复如下：（client:oracle-test; server:master）
# ./bplist -C oracle-test -S master -t 4 -R / 查看nbu的备份文件



#rman target /
Rman>startup nomount
Rman>run {
allocate channel ch00 type 'sbt_tape';
send 'NB_ORA_CLIENT=oracle-test';
send 'NB_ORA_SERV=master';
restore controlfile from '/cntrl_11_1_873557906';
release channel ch00;
}
Rman>alter database open resetlogs; 要打开数据时，重置重做日志，即将重做日志的sequence置零
到此，控制文件就已经恢复完成了。
alter database open resetlogs是要打开数据时，重置重做日志，即将重做日志的sequence置零，为什么要重置重做日志呢？
不完全恢复后，原来的online redo log里面包含的是未做恢复前的数据，而这些数据对于恢复后的数据库不再有效，所以数据库会要求在Open之前先对online redo log的sequence置零。
Resetlogs命令表示一个数据库逻辑生存期的结束和另一个数据库逻辑生存期的开始，每次使用Resetlogs命令的时候，SCN不会被重置，不过oracle会重置日志序列号，而且会重置联机重做日志内容。
加上resetlogs，只是修改了日志序列号，并没有删除数据。所有数据是仍然存在的。
注:
recover和restore的区别：
restore just copy the physical file, recover will consistent the database.
restore 是还原，文件级的恢复。就是物理文件还原。
recover 是恢复，数据级的恢复。逻辑上恢复，比如应用归档日志、重做日志，全部同步，保持一致。
用我自己的土话讲就是，用restore先把备份文件拷贝到数据库目录下进行替换，再用recover经过一些处理，数据库就恢复正常了。
1、restore 命令：用于还原已经备份的数据文件。
（1）、restore database 还原所有的数据文件。
（2）、restore tablespace 还原特定表空间的数据文件。
（3）、restore datafile 还原特定的数据文件。
（4）、restore controlfile 还原控制文件。
（5）、restore archivelog 还原归档日志文件。
2、recover 命令：当数据库需要应用归档日志文件恢复数据文件时，使用recover命令。使用该命令数据库系统会自动应用归档的日志文件。
（1）、recover database 恢复所有的数据文件。
（2）、recover tablespace 恢复特定表空间的数据文件。
（3）、recover datafile 恢复特定的数据文件。
restore 只是用备份来还原,recover是用archivelog或者online log
举例说明：
假设我时间点A,做了个备份,时间点B数据库挂了
restore database ;// 这个操作利用时间点A做的备份来还原,返回到时间点A
recover database ;//这个操作利用archivelog and online log做recover,从时间点A,推进到时间点B

第七章 卸载NetBackup客户端软件

Use the following procedure to remove all NetBackup client software components from a UNIX client. To remove NetBackup software from a UNIX client 1、 Log in to the client system as the root user. 2、Stop the NetBackup daemons by entering the following command: /usr/openv/netbackup/bin/bp.kill_all 3、Identify any installed add-on products by using the following command: AIX lslpp -L HP-UX swlist Linux rpm -qa Solaris pkginfo Remove each identified add-on product. ……………… 11、For all clients, navigate to the /usr/openv directory and proceed as follows: Warning: The rm -f /usr/openv command also removes any add-on products that are installed on this computer. ■ If /usr/openv is the actual directory, run the following command: rm -rf /usr/openv ■ If /usr/openv is a symbolic link to that directory, run the following commands: cd /usr/openv pwd ls Warning: Before you continue, make sure that you are at the correct location and verify that the subdirectories are what you expect them to be. To help prevent removing the wrong directories, the previous commands verify your current location and list the files in that directory. After you verify the directory location and its contents, remove the directory with the next commands. rm -rf * cd / rm -f /usr/openv 12、For Linux systems only: If you modified the startup and the shutdown scripts, run the following command: /sbin/chkconfig --del netbackup 13 Remove the following startup scripts: AIX /etc/rc.netbackup.aix Linux Red Hat /etc/rc.d/init.d/netbackup /etc/rc.d/rc0.d/K01netbackup /etc/rc.d/rc1.d/K01netbackup /etc/rc.d/rc2.d/S77netbackup /etc/rc.d/rc3.d/S77netbackup /etc/rc.d/rc5.d/S77netbackup /etc/rc.d/rc6.d/K01netbackup Other clients /etc/init.d/netbackup /etc/rc0.d/K01netbackup /etc/rc1.d/K01netbackup /etc/rc2.d/S77netbackup
