通过RMAN备份搭建单节点ADG（oracle11g）

1、修改/etc/hosts 建议：生产端和DG端保持一致

生产端：

[root@primary ~]# more /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.186.87 primary

192.168.186.88 standby

DG端：

[root@standby ~]# more /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.186.88 standby

192.168.186.87 primary

2、修改数据库为归档日志模式、强制日志模式

[oracle@primary ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Tue Aug 4 22:15:54 2015

Connected to an idle instance.

SQL> startup mount;

ORACLE instance started.

Total System Global Area 409194496 bytes

Fixed Size 2228864 bytes

Variable Size 276827520 bytes

Database Buffers 125829120 bytes

Redo Buffers 4308992 bytes

SQL> archive log list

Database log mode No Archive Mode

Current log sequence 6

SQL> alter database archivelog;

Database altered.

SQL> select force_logging from v$database;

FOR

---

SQL> alter database force logging;

Database altered.

3、在生产端修改参数文件

SQL> alter system set log_archive_dest_1 = 'LOCATION=/archive/orcl' scope=both;

System altered.

SQL> alter system set log_archive_dest_2 = 'SERVICE=standby arch ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl' scope=both;

System altered.

SQL> alter system set log_archive_dest_state_1 = ENABLE scope=both;

System altered.

SQL> alter system set log_archive_dest_state_2 = ENABLE scope=both;

System altered.

SQL> alter system set db_file_name_convert = '/oradata/orcl/ ','/oradata/orcl_standby ' scope = spfile;

System altered.

SQL> alter system set log_file_name_convert = '/oradata/orcl/ ','/oradata/orcl_standby ' scope = spfile;

System altered.

4、配置生产端和DG端网络服务名tnsnames.ora 建议：保持一致验证：tnsping

生产端：

[oracle@primary admin]$ more tnsnames.ora

# tnsnames.ora Network Configuration File: /u01/app/base/product/11.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

STANDBY =

(DESCRIPTION =

(ADDRESS_LIST =

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

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

ORCL =

(DESCRIPTION =

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

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

DG端：

[oracle@standby admin]$ more tnsnames.ora

# tnsnames.ora Network Configuration File: /u01/app/base/product/11.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

STANDBY =

(DESCRIPTION =

(ADDRESS_LIST =

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

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

ORCL =

(DESCRIPTION =

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

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

Tnsping service_names验证

5、将生产端$ORACLE_HOME/dbs/下的密码文件orapwORACLE_SID传至备机,可以用ssh/ftp

orapwd file=orapworcl password=oracle(建议拷贝，不然报ORA-16191)

6、创建生产端的pfile并传至DG端

生产端：

[oracle@primary ~]$ scp initorcl.ora [email protected]:/u01/app/base/product/11.2.0/db_1/dbs

[email protected]'s password:

initorcl.ora 100% 769 0.8KB/s 00:00

DG端：

[oracle@standby dbs]$ ls -rlt

total 8

-rw-r-----. 1 oracle oinstall 1536 Aug 4 23:53 orapworcl

-rw-r--r--. 1 oracle oinstall 769 Aug 4 23:55 initorcl.ora

7、创建standby控制文件、数据文件、归档日志，并传至DG端的相同路径下

[oracle@primary ~]$ rman target /

Recovery Manager: Release 11.2.0.3.0 - Production on Tue Aug 4 23:26:09 2015

8、在DG端修改pfile，并启动实例到NOMOUNT状态

[oracle@standby dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Wed Aug 5 16:56:13 2015

9、在DG端，通过RMAN连接到生产库和auxiliary数据库，结束后备库自动启到MOUNT状态

[oracle@standby dbs]$ rman target sys/oracle@orcl auxiliary sys/oracle

Recovery Manager: Release 11.2.0.3.0 - Production on Wed Aug 5 16:57:14 2015

connected to target database: ORCL (DBID=1414669689)
