oracle 11g RMAN新特性active database duplication createing standby

Network-Enabled Database Duplication Without Backups
Prior to Oracle 11g, an RMAN database duplication to a different host required copies of
the relevant backups and archived redo logs to be manually copied to the remote server.
Oracle 11g allows active database duplication, so there is no need for the presence of pre-existing
database backups and manual copying of files.
Once the DUPLICATE command is initiated, RMAN automatically performs the following steps:
Copies the spfile to the destination server.
Starts the auxiliary instance with the spfile.
Copies the relevant database files and archived redo logs over the network to the destination server.
Recovers the database.
Opens the database with the RESETLOGS option.
This method is suitable for creating a duplicate database or physical standby database.
也就是说oracle 11g 用DUPLICATE命令 创建standby database 或 duplicate database 不再需要主库的备份数据文件,
归档日志文件,参数文件,控制文件等
而是直接从主库拷贝到standby库,不需要做copy文件手工操作
需要做手工的地方就是拷贝主库的密码文件PWDprimary.ora 命名为PWDstandby.ora文件
oracle 11g rman新特性 active database duplication
下面是在同一台机利用active database duplication 搭建standby 的操作过程
操作系统环境windows 2003 server +oracle 11.1.0.6
数据库名 primary
主库 sid=primary
存放数据文件路径:d:\app\administrator\oradata\primary\
存放归档文件路径:d:\primary\archivelog
闪回文件路径:d:\app\administrator\flash_recovery_area\primary
备库
sid=primary
存放数据文件路径:d:\app\administrator\oradata\standby\
存放归档文件路径:d:\standby\archivelog
闪回文件路径:d:\app\administrator\flash_recovery_area\standby
建好备库的存放文件相关目录
d:\app\administrator\admin 目录下建立standby 目录
d:\app\administrator\admin\standby 目录下建立以下三个文件夹
adump, dpdump, pfile
操作步骤如下:
1.在windows下新建standby 实例,用oradim工具
C:\Documents and Settings\Administrator>oradim -NEW -SID standby -STARTMODE auto -S
RVCSTART system
Instance created.
The Oracle standby VSS Writer Service service is starting.
The Oracle standby VSS Writer Service service was started successfully.
2.在f:目录下新建个文件init.ora文件 用于启动standby 实例
编辑init.ora 输入 db_name=primary 保存退出
3.编辑listener.ora与tnsnames.ora文件 使能够与备库相同
listener.ora文件如下:
# listener.ora Network Configuration File: D:\app\Administrator\product\11.1.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = paul2003)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_NAME =primary)
(ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1)
(SID_NAME =primary)
)
(SID_DESC =
(GLOBAL_NAME =primary)
(ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1)
(SID_NAME =standby)
)
)
tnsnames.ora文件如下:
primary =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.1.227)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = primary)
)
)
standby =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.1.227)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME =standby)
)
)
重新启动监听
lsnrctl stop
lsnrctl start
4.启动standby实例到nomount状态
C:\Documents and Settings\Administrator>set oracle_sid=standby
C:\Documents and Settings\Administrator>sqlplus / as sysdba

5.在执行DUPLICATE之前,首先设置PRIMARY数据库为归档模式,FORCE LOGGING和DATA GUARD相关的初始化参数:
C:\Documents and Settings\Administrator>set oracle_sid=primary
C:\Documents and Settings\Administrator>sqlplus / as sysdba
SQL*Plus: Release 11.1.0.6.0 - Production on Thu Jul 31 11:17:30 2008

SQL> ALTER DATABASE FORCE LOGGING;

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_1 = 'LOCATION=d:\primary\archivelog VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=primary' SCOPE = SPFILE;

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 = 'SERVICE=standby ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=standby' scope=spfile;
System altered.
SQL> ALTER SYSTEM SET DB_FILE_NAME_CONVERT='PRIMARY','STANDBY';
System altered.
SQL> ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='PRIMARY','STANDBY'; 用于搭建过程中主库和备库目录转换
如果是两台机器相同目录 则不需要设置这两个参数
System altered.

6.登录主库 执行duplicate命令
C:\Documents and Settings\Administrator>set oracle_sid=primary
C:\Documents and Settings\Administrator>rman target / auxiliary mailto:sys/abcdefg@stan]sys/abcdefg@stan
dby log=c:\rman.log
