oracle 10g 数据库RMAN创建 Data Guard方法

一、主从监听程序都一样，如下：

# listener.ora Network Configuration File: /data/oracle/oracle/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = sms)

(ORACLE_HOME = /data/oracle/oracle)

(SID_NAME = sms)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = Server-Name)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

)

)

INBOUND_CONNECT_TIMEOUT_LISTENER = 0

SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF

二、主从tnsnames.ora文件内容，都一样的，主库配置为primary，从库配置为standby：

# tnsnames.ora Network Configuration File: /data/oracle/oracle/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

)

PRIMARY=

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = *.*.*.99)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = sms)

)

)

STANDBY=

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = *.*.*.27)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = sms)

)

)

四、在从库上建好相应的目录，免得出现找不到目录的错误

五、在主库上单独备份control文件(**必须的**)，备份整个数据库和需要的归档日志文件，拷贝到从库的相同目录下，目录不同就不好使

--备份控制文件

RMAN> backup current controlfile for standby format '/data/rman_backup/control_new.ctl';

RMAN> sql "alter system switch logfile";

--压缩备份数据库(局域网可以不用压缩备份)：

RMAN> backup as compressed backupset database format '/data/rman_backup/2_%T_%U.bak' plus archivelog;

--可以分开备份归档日志，因为会自动备份到闪回区里面

RMAN> backup as compressed backupset database format '/data/rman_backup/full_%T_%U.bak';

*****备份所有归档日志

RMAN> backup archivelog all format '/data/rman_backup/archive_%T_%U.bak';

*****备份最近一天的归档日志

RMAN> backup archivelog from time "sysdate-1" until time "sysdate" format ='/data/rman_backup/archivelog_%T_%U.bak' ;

六、拷贝init参数文件和远程密码文件到从库

从库启动到nomount状态

SQL> conn /as sysdba

SQL> startup nomount

七、在主库用RMAN执行连接主库和从库的操作

RMAN> connect catalog rman/*****

RMAN> connect target / (远程连主库则 connect targetrman/***@primary)

RMAN> connect auxiliary sys/******@standby (用sys用户连接)

八、执行命令：

RMAN> duplicate target database for standby dorecover;

RMAN> duplicate target database for standby dorecover nofilenamecheck;

如果主库和从库的目录一模一样则加上nofilenamecheck，否则报错如下：

RMAN-05001: auxiliary filename /data/oracle/oradata/sms/develptbs01.dbf conflicts with a file used by the target database
