1. RMAN服务器的配置:

以下在Dataguard Server (目錄服务器)上配置.

1.0 建立RMAN数据库(比如SID=RMAN) .

1.1 建立RMAN用户表空间(表空间大小设置为500m左右即可) .

create tablespace rman_data

datafile '/u01/data/rman_data1.dbf' size 500M

extent management local uniform size 5M ;

1.2 建立RMAN用户:

create user rman identified by rman

default tablespace rman_data

temporary tablespace temp ;

1.3 给RMAN用户授于相关系统权限:

grant resource, connect, recovery_catalog_owner to rman;

1.4 在Dataguard Server(目錄服务器)上设置tnsnames.ora 用于連target服务器(Primary DB) .

tnsnames.ora 文件中加入以下内容:

DELL_RAC1 =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.161.8.71)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

(INSTANCE_NAME = orcl1)

)

)

1.5 連接目标服务器与CATALOG服务器. (在Dataguard Server上的RMAN数据库上操作)

rman target sys/oracle@dell_rac1 catalog rman/rman(user/password必须为目标服务器上的拥有sysdba权限的用户.如:sys)

1.6 在目标服务器上建立CATALOG 目錄.

CREATE CATALOG

1.7 在CATALOG服务器上注册目标服务器.

REGISTER DATABASE;

到这里,RMAN备份环境已经准备好了,幷已連接至目标与目錄服务器.

2. 建立Data Guard

2.1 COPY目标服务器上(Primary DB Server)的初始化參數文件及密码文件到Data Guard相对应目錄.

2.2 使用RMAN的Image copy拷贝目标服务器上的.DBF文件至Data Guard相应目錄.(见后面的详细介绍) .

2.2.1 使用REPORT SCHEMA可列出将要拷贝的所有目标數据库上的數据文件.

2.2.2 使用下面的SQL生成所有數据文件的copy脚本.

SELECT 'datafile '||''''||name||''''||' to '||''''||'/data'||name||''''||',' FROM v$datafile; 或者

SELECT 'datafile '||''''||name||''''||' to '||''''||name||''''||',' FROM v$datafile;

RMAN IMAGE COPY脚本:

RUN {

ALLOCATE CHANNEL XXXXX DEVICE TYPE DISK;

COPY

...........,

…..----- 这裡放入上面SQL生成的脚本 .

……… ;

RELEASE CHANNEL XXXX;}

脚本例子 (如果在Data Guard Server上文件路径有变化, 即与Primary DB上路径不一样, 我们会在生成控制文件后, 在Data Guard DB上Mount狀态下使用 alter database rename file 更改數据文件路径, 脚本中前面的文件路径表示Primary DB上的路径, 后面的路径表示Data Guard Server上的文件路径 ) .

以下脚本例子中的 /backup目录是dataguard上的/data目录影射到Primary DB上的Mount点Label (详细的nfs mount见后面的nfs mount介绍) .

RUN {

ALLOCATE CHANNEL XXXX DEVICE TYPE DISK;

在 Copy datafile ｀/ocfs_data/orcl/xx.dbf＇ to ｀/backup/ocfs_data/orcl/xx.dbf＇中.

第一个｀/ocfs_data/orcl/xx.dbf＇是目标服务器的數据文件地址. ｀/backup/ocfs_data/orcl/xx.dbf 是挂载到目标服务器上的dataguard的相应目錄.

假设脚本文件保存为 rman.txt 文件 .

說明:

需要先将将要成为dataguard服务器的文件存放目錄使用NFS映像至目标服务器(Primary DB Server ) 相关目錄.

具体步骤如下:

Linux下NFS的配置

2.3. NFS server端(在此处为Data Guard服务器)及客户端(Primary DB Server)设置:

2.3.1 在/etc/exports 发布挂载的目錄.

如: /data *(rw,no_root_squash)

/data为data guard server上分享的目錄,*表示允许任何主机分享,rw,no_root_squash为參數

代表意义如下:

rw: 可讀写的权限

ro: 只讀的权限

no_root_squash: 登入 NFS 主机使用分享目錄的使用者，如果是 root 的话，那么对于这个分享的目錄來說，他就具有 root 的权限！

root_squash: 在登入 NFS 主机使用分享之目錄的使用者如果是 root 时，那么这个使用者的权限将被压缩成为匿名使用者.

2.3.2 在Data Gurad DB Server上启动兩个相关服务

#/etc/rc.d/init.d/portmap start (or:#service portmap start)

#/etc/rc.d/init.d/nfs start (or:#service nfs start)

2.3.3. NFS客户端的设定(TARGET服务器, 即Primary database Server )

不用其它设定,直接挂载就可以了

#mount -t nfs dataguard_server_ip:/directory /mountpoint

/mountpoint 为Primary Database Server上的挂载点 .

如:

mount -t nfs 10.161.8.83:/data /backup
