RMAN复制数据库(六)

在相同主机上创建复制数据库
当在与目标数据库相同主机上创建复制数据库就与在远程主机上使用不同目录结构复制数据库一样。可以在目标数据库的Oracle Home目录中创建复制数据库,但数据库名必须不同于目标数据库。

1.创建辅助实例的密码文件(这里辅助实例名为aux)

[oracle@oracle11g dbs]$ orapwd file=/u01/app/oracle/product/10.2.0/db/dbs/orapwaux password=oracle entries=10;
[oracle@oracle11g dbs]$ ls -lrt
-rw-r----- 1 oracle oinstall    2560 Mar 24 14:47 orapwdup

2.创建辅助实例网络连接,修改监听文件,使用静态监听来监听辅助实例

[oracle@oracle11g dbs]$ vi listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
     (SID_NAME = aux)
      (ORACLE_HOME =/u01/app/oracle/product/10.2.0/db)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.11)(PORT = 1521))
    )
  )

给辅助实例增加网络服务名

[oracle@oracle11g dbs]$ vi tnsnames.ora
aux =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME =aux)
      (UR=A)
    )
  )

测试网络连接

[oracle@oracle11g dbs]$ export ORACLE_SID=aux
[oracle@oracle11g dbs]$ sqlplus /nolog

SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 14:57:08 2015

Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.

SQL> conn sys/oracle@dup as sysdba
Connected to an idle instance.

3.创建辅助实例的参数文件

[oracle@oracle11g dbs]$ vi initdup.ora

db_name=aux
db_unique_name=aux
control_files= /u01/app/oracle/oradata/aux/control01.ctl
db_file_name_convert=('/u01/app/oracle/oradata/test/','/u01/app/oracle/oradata/aux/')
log_file_name_convert=('/u01/app/oracle/oradata/test/','/u01/app/oracle/oradata/aux/')
remote_login_passwordfile=exclusive
compatible = 10.2.0.5.0
db_block_size=8192
sga_target=160M
sga_max_size=160M
pga_aggregate_target=16M



[oracle@oracle11g dbs]$ export ORACLE_SID=aux
[oracle@oracle11g dbs]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 21:13:44 2015

Connected to an idle instance.

SQL> create spfile from pfile='/u01/app/oracle/product/10.2.0/db/dbs/initaux.ora';

File created.

4.启动辅助实例

[oracle@oracle11g dbs]$ export ORACLE_SID=aux
[oracle@oracle11g dbs]$ sqlplus /nolog

SQL*Plus: Release 10.2.0.5.0 - Production on Tue Mar 24 21:13:44 2015

断开连接

SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

这里一定要断开启动辅助实例的会话否则在执行复制操作时会出现如下错误 :

配置辅助实例的网络服务名

5.加载或打开目标数据库

[oracle@oracle11g ~]$ sqlplus /nolog

6.确保有需要的备份和归档重做日志,对目标数据库(被复制的数据库)进行备份(包含数据文件和归档重做日志)

[oracle@oracle11g admin]$ export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
[oracle@oracle11g admin]$ rman target sys/zzh_2046@test catalog rman/rman@jy

7.执行duplicate命令,如果没有配置自动通道,那么至少手动分配一个辅助实例如果是使用PFILE参数文件启动辅助实例需要指定pfile参数文件,且pfile参数文件必须存储在运行RMAN执行复制的主机上。这里辅助实例使用SPFILE参数文件来启动,并使用自动通道:

[oracle@oracle11g ~]$ export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'
