千家信息网最后更新 2025年01月25日oracle 11g duplicate active database 建立物理DG

环境：

primary:

OS: Red Hat Enterprise　5.8

IP: 10.131.119.118

DBVersion: 11.2.0.3.0

db_name: orcl

db_unique_name: orcl

standby:

OS: Red Hat Enterprise　5.8

IP: 10.131.119.119

DBVersion: 11.2.0.3.0

db_name: orcl

db_unique_name: std

步骤1：将主库设置为归档模式与force_logging模式

SQL>shutdown immediate;

SQL>startup mount;

SQL>alter database archivelog;

SQL>alter database open;

SQL>alter database force logging;

SQL> select DBID,NAME,LOG_MODE,FORCE_LOGGING from v$database;

DBID NAME LOG_MODE FOR

---------- --------- ------------ ---

1414106639 ORCL ARCHIVELOG YES

步骤2：将主库的pfile文件和密码文件拷备到备库

[oracle@CS-SI-DG01 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jan 27 16:05:21 2016

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create pfile from spfile;

File created.

SQL> exit

Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

[oracle@CS-SI-DG01 dbs]$ scp initorcl.ora 10.131.119.119:/u2/oracle/product/11.2.0/dbhome_1/dbs/initstd.ora

oracle@10.131.119.119's password:

stty: standard input: Invalid argument

initorcl.ora 100% 1112 1.1KB/s 00:00

[oracle@CS-SI-DG01 dbs]$ scp orapworcl 10.131.119.119:/u2/oracle/product/11.2.0/dbhome_1/dbs/orapwstd

oracle@10.131.119.119's password:

stty: standard input: Invalid argument

orapworcl 100% 1536 1.5KB/s 00:00

步骤3：设置主库的监听与TNS

监听：

[oracle@CS-SI-DG01 admin]$ cat listener.ora

# listener.ora Network Configuration File: /u2/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 = orcl)

(ORACLE_HOME = /u2/oracle/product/11.2.0/dbhome_1)

(SID_NAME = orcl)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.118)(PORT = 1521))

)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

ADR_BASE_LISTENER = /u2/oracle

[oracle@CS-SI-DG01 ~]$ lsnrctl reload

TNS：

[oracle@CS-SI-DG01 admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.118)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

std =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.119)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = std)

)

步骤4：修改主库的参数

[oracle@CS-SI-DG01 admin]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jan 27 16:19:40 2016

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> alter system set log_archive_config='dg_config=(orcl,std)';

System altered.

SQL> alter system set log_archive_dest_2='SERVICE=std ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=std';

System altered.

SQL> alter system set log_archive_dest_state_2=enable;

System altered.

SQL> alter system set log_archive_dest_state_1=enable;

System altered.

SQL> alter system set fal_server='std';

System altered.

SQL> alter system set fal_client='orcl';

System altered.

SQL> alter system set standby_file_management='auto';

System altered.

注：修改好参数后重新启动数据库

步骤5：修改备库参数文件

[oracle@CS-SI-DG02 dbs]$ cat initstd.ora

*.audit_file_dest='/u2/oracle/admin/std/adump'

*.audit_trail='db'

*.log_file_name_convert=('/oradata/orcl','/oradata/std')

*.db_file_name_convert=('/oradata/orcl','/oradata/std')

*.db_unique_name='std'

步骤6：在备库创建目录

[oracle@CS-SI-DG02 dbs]$ mkdir -p /u2/oracle/admin/std/adump

[oracle@CS-SI-DG02 dbs]$ mkdir -p /oradata/std/

[oracle@CS-SI-DG02 dbs]$ mkdir -p /oradata/arch/std

步骤7：设置备库的监听与TNS

监听：

[oracle@CS-SI-DG02 admin]$ cat listener.ora

# listener.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

)

ADR_BASE_LISTENER = /u2/oracle

STENER =

)

[oracle@CS-SI-DG02 admin]$ lsnrctl reload

TNS：

[oracle@CS-SI-DG02 admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.118)(PORT = 1521))

)

(CONNECT_DATA =

)

std =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.119)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = std)

)

步骤8：将备库启动到nomount状态

[oracle@CS-SI-DG02 admin]$ export ORACLE_SID=std

[oracle@CS-SI-DG02 admin]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jan 27 16:56:58 2016

步骤9：在备库恢复数据库

[oracle@CS-SI-DG02 admin]$ rman target sys/oracle@orcl auxiliary sys/oracle@std nocatalog
