中财网阿里云服务器登录密码:RMAN： 从NBU备份磁带库恢复到异机案例
来源：百度文库 编辑：中财网 时间：2024/04/29 05:31:40
人力资源系统数据库于
本次恢复主要是获取人力资源系统生产库在NBU Veritas磁带库上的全备份数据到应急系统数据库上进行完全恢复。
下面是具体的操作步骤及过程：
1. 在应急系统数据库上创建新的数据库实例：
1) 登录应急数据库服务器：
#su – oracle
$who
$export DISPLAY=10.xxx.xx.xxx:0.0
$dbca
（然后在图型界面中进行ORACLE数据库安装）
2) 配置相关数据库信息：
设置实例名，数据文件存放位置等,本次数据库的实例名：JMHRMS
2. 在应急系统数据库上安装配置NBU管理客户端：
1） 安装NBU的CLIENT：
#mount -rv cdrfs /dev/cd0 /mnt
#cd /mnt
#ls
#./install *nbuserver:jmbackupsrv (10.151.17.21)
2） 安装NBU的AGENT：
#mount -rv cdrfs /dev/cd0 /mnt
#cd /mnt
#ls
#./install *nbuserver:jmbackupsrv
3） 配置NBU的AGENT：
#su - oracle
#cd /usr/openv/netbackup/bin
#./oracle_link
LIBOBK path: /usr/openv/netbackup/bin
ORACLE_HOME: /oracle/10.2
Oracle version:
Linking LIBOBK:
ln -s /usr/openv/netbackup/bin bobk.a64 /oracle/10.2 b bobk.a
Done
Please check the trace file located in /tmp/make_trace.684536
to make sure the linking process was successful.
4） 测试AGENT是否成功：
#su – oracle
$rman target /
RMAN>run {
allocate channel ch01 TYPE 'SBT_TAPE';
release channel ch01;
} **测试连接磁带库是否成功
3. 登录人力资源生产数据库检查该机的RMAN配置是否正确：
1） 检查并修改RAMAN配送配置：
jm_hr_db[/]#su - oracle
$ORACLE_SID: jmhrms
$ORACLE_HOME: /oracle/product/
jm_hr_db[/home/oracle]@rman target /
Recovery Manager: Release
Copyright (c) 1982, 2007, Oracle. All rights reserved.
connected to target database: JMHRMS (DBID=3805380100)
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/product/
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully stored
**配置修改成功
2） 进行SPFILE文件备份：
RMAN> run {
2> allocate channel ch1 type 'sbt_tape';
3> backup current controlfile;
4> release channel ch1;
5> }
released channel: ORA_DISK_1
allocated channel: ch1
