--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
PL/SQL Release 11.2.0.2.0 - Production

数据库规划(db_unique_name):
主库: DREAM
备库: DREAM01

操作步骤如下:

1.检查主库是否为归档模式，并且主库为force logging，(database flashback模式可选，选择有利于备库在failover模式迅速恢复)

SQL> select log_mode,force_logging from v$database;

LOG_MODE FOR
------------ ---
ARCHIVELOG NO

SQL> alter database force logging;

Database altered.

SQL> select log_mode,force_logging from v$database;

LOG_MODE FOR
------------ ---
ARCHIVELOG YES

SQL>

2.检查是否创建standby log file,假如没有创建，则创建
standby log file的文件大小和redo log file 文件大小一样，并且组数为redo log group count * thread count + 1

SQL> select * from v$logfile;
rows will be truncated

SQL> select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS
---------- ---------- ---------- ---------- ---------- ---------- --- ----------

3 1 3 52428800 512 1 YES INACTIVE

SQL> select 52428800/1024/1024 from dual;

3,修改主数据库配置DATAGUARD参数:

alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(DREAM,DREAM01)';

alter system set LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=DREAM';

alter system set LOG_ARCHIVE_DEST_2='SERVICE=DREAM01 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=DREAM01';

alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;

alter system set FAL_SERVER=DREAM01;

alter system set FAL_CLIENT=DREAM;

alter system set DB_FILE_NAME_CONVERT='/media/oracle/oradata/DREAM01/','/media/oracle/oradata/DREAM/' scope=spfile;

alter system set LOG_FILE_NAME_CONVERT='/media/oracle/oradata/DREAM01/','/media/oracle/oradata/DREAM/' scope=spfile;

SQL> alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(DREAM,DREAM01)';

System altered.

SQL> alter system set LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=DREAM';

System altered.

SQL> alter system set LOG_ARCHIVE_DEST_2='SERVICE=DREAM01 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=DREAM01';

SQL> alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;

SQL> alter system set LOG_FILE_NAME_CONVERT='/media/oracle/oradata/DREAM01/','/media/oracle/oradata/DREAM/' scope=spfile;

4,配置主备监听器,tnsname.ora文件，使双方可以连上:

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin$ vi listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ATS.COM)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = ATS)
)
(SID_DESC =
(GLOBAL_DBNAME = DREAM.COM)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = dream)
)
(SID_DESC =
(GLOBAL_DBNAME = DREAM01.COM)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = dream01)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = admtps-Sun-Fire-X4150)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

ADR_BASE_LISTENER = /u01/app/oracle

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin$ lsnrctl reload

The command completed successfully
oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin$

编辑 tnsnames.ora文件添加

DREAM01 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.201)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DREAM01.COM)
)
)

配置完毕以后用tnsping看是否能够相互ping通;

SQL> host;
oracle@admtps-Sun-Fire-X4150:/media/oracle/fast_recovery_area$ tnsping dream

TNS Ping Utility for Linux: Version 11.2.0.2.0 - Production on 05-JUN-2012 16:16:25

OK (0 msec)

oracle@admtps-Sun-Fire-X4150:/media/oracle/fast_recovery_area$

5.配置standby database

5.1拷贝主库的密码文件到备机，然后改成备库自己的

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/dbs$ cp orapwDREAM orapwDREAM01

5.2创建备库初始化参数:

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/dbs$ more initDREAM01.ora
db_name = 'DREAM01'
db_unique_name = 'DREAM'
db_domain = 'COM'

5.3创建备库文件存放路径:

SQL> show parameter user_dump_dest

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
user_dump_dest string /media/oracle/diag/rdbms/dream

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/dbs$mkdir /media/oracle/oradata/DREAM01

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/dbs$mkdir /media/oracle/diag/rdbms/dream01

5.4用SQLPLUS启动备库到nomount状态:

oracle@admtps-Sun-Fire-X4150:/media/oracle/fast_recovery_area$ export ORACLE_SID=DREAM01
oracle@admtps-Sun-Fire-X4150:/media/oracle/fast_recovery_area$ sqlplus / as sysdba

Connected to an idle instance.

SQL> startup nomount pfile="/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initDREAM01.ora"

SQL> host;
oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/dbs$

5.5 用rman在主库上连接主库和辅助库（备库）,执行创建备库操作:

rman duplicate.log

conn target sys/@dream;
conn auxiliary sys/@dream01;

run {
duplicate target database for standby from active database
spfile
parameter_value_convert 'DREAM','DREAM01'
set db_unique_name='DREAM01'

set log_archive_dest_2='service=dream ASYNC valid_for=(ONLINE_LOGFILE,PRIMARY_ROLE) db_unique_name=DREAM';
}

oracle@admtps-Sun-Fire-X4150:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin$ rman
