在Oracle 11gR2上使用RMAN实现整库迁移

在Oracle 11gR2上使用RMAN实现整库迁移

在Oracle 11gR2上使用RMAN实现整库迁移

背景：

1. 在Auxiliary 创建pfile 参数文件
 
[oracle@localhost dbs]$ pwd
/u01/oracle11gR2/product/11.2.0/db_1/dbs
[oracle@localhost dbs]$ more initv112.ora
*.DB_NAME=v112
*.control_files='/u01/oracle11gR2/oradata/v112/control01.ctl','/u01/oracle11gR2/flash_recovery_area
/v112/control02.ctl'
*.db_block_size=8192
*.compatible='11.2.0.1'
_compression_compatibility="11.2.0"   注：这个隐含参数可以绕过11.2.0.1的bug
*.db_recovery_file_dest_size=4294967296
*.db_recovery_file_dest='/u01/oracle11gR2/flash_recovery_area'
*.audit_file_dest='/u01/oracle11gR2/admin/v112/adump'
    
2. 在Auxiliary库上创建口令文件
[oracle@localhost dbs]$ pwd
/u01/oracle11gR2/product/11.2.0/db_1/dbs
[oracle@localhost dbs]$ orap
orapipe  orapki   orapwd   orapwdO 
[oracle@localhost dbs]$ orapwd file=orapwv112 password=Your password   
3. 在Auxiliary库创建相关的目录结构
[oracle@localhost dbs]$ mkdir /u01/oracle11gR2/admin/v112/
[oracle@localhost dbs]$ mkdir /u01/oracle11gR2/oradata/v112/ 
注：在duplicate过程中，如果目录不存在，则会报错“ORA-27040: file create error, unable to create file”
 
4. 启动Auxiliary 到nomout 状态
 
SQL> conn / as sysdba;
Connected to an idle instance.
SQL> startup nomount pfile=‘/u01/oracle11gR2/product/11.2.0/db_1/dbs/initv112.ora’
ORACLE instance started.
Total System Global Area  146472960 bytes
Fixed Size                  1335080 bytes
Variable Size              92274904 bytes
Database Buffers           50331648 bytes
Redo Buffers                2531328 bytes
    
5. 在Target 和Auxiliary 都配置Oracle Net（Listener.ora and tnsnames.ora）[可选] 
 
[oracle@localhost admin]$ more tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/oracle11gR2/product/11.2.0/db_1/network/admin/tnsna
mes.ora
# Generated by Oracle configuration tools.

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.133)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = v112)
    )
  )
LISTENER_v112 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.133)(PORT = 1521))
ORCL =
  (DESCRIPTION =

    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID_NAME = orcl
    )
  )
LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.133)(PORT = 1521))
 
[oracle@localhost admin]$ more listener.ora
# listener.ora Network Configuration File: /u01/oracle11gR2/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.133)(PORT = 1521))
    )
  )
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = v112)
      (ORACLE_HOME = /u01/oracle11gR2/product/11.2.0/db_1)
      (SID_NAME = v112)
    )
  )
 
LISTENER2 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.133)(PORT = 1522))
    )
  )
 
SID_LIST_LISTENER2 =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /u01/oracle11gR2/product/11.2.0/db_1)
      (SID_NAME = orcl)
    )
  )
 
ADR_BASE_LISTENER1 = /u01/oracle11gR2
